ios Mengunggah Gambar dan Teks menggunakan HTTP POST

96

Terima kasih sudah membaca.

Saya baru mengenal iOS dan saya mencoba mengunggah Gambar dan teks yang digunakan multi-part form encodingdi iOS.

The curlsetara adalah sesuatu seperti ini:curl -F "param1=value1" -F "[email protected]" "http://some.ip.address:5000/upload"

The curlperintah di atas kembali respon yang benar diharapkanJSON.

Masalah: Saya terus mendapatkan permintaan HTTP 400 yang berarti saya melakukan kesalahan saat membuat Badan HTTP POST.

Apa yang Saya Lakukan: Untuk beberapa referensi, saya mencoba aplikasi Flickr API iOS "Ukuran POST terlalu besar!" dan Tujuan C: Bagaimana cara mengunggah gambar dan teks menggunakan HTTP POST? . Tapi, saya tetap mendapatkan HTTP 400.

Saya mencoba ASIHttpRequesttetapi memiliki masalah yang berbeda di sana (panggilan balik tidak pernah dipanggil). Tapi, saya tidak menyelidiki lebih lanjut sejak saya mendengar pengembang berhenti mendukung perpustakaan: http://allseeing-i.com/[request_release] ;

Bisakah seseorang membantu saya?

Saya menggunakan NSURLConnection. stackoverflow.com/questions/8042360/…
XJones
Terima kasih untuk tautannya. Sebenarnya, itu masih memberi saya kesalahan 400. Saya mencetak badan pos http - dan alih-alih gambar, yang saya lihat hanyalah dua karakter sampah. Jadi, ketika Anda menambahkan imageData, itu adalah tipe NSData - haruskah itu menjadi string berenkode base64? BTW, imageToPost saya adalah tipe UIImage.

Kode itu seperti yang tertulis berfungsi di aplikasi saya untuk memposting gambar ke server web kami (Linux / PHP). Gambar tersebut adalah gambar UII.

Berikut kode dari aplikasi saya untuk memposting gambar ke server web kami:

// Dictionary that holds post parameters. You can set your post parameters that your server accepts or programmed to accept.
NSMutableDictionary* _params = [[NSMutableDictionary alloc] init];
[_params setObject:[NSString stringWithString:@"1.0"] forKey:[NSString stringWithString:@"ver"]];
[_params setObject:[NSString stringWithString:@"en"] forKey:[NSString stringWithString:@"lan"]];
[_params setObject:[NSString stringWithFormat:@"%d", userId] forKey:[NSString stringWithString:@"userId"]];
[_params setObject:[NSString stringWithFormat:@"%@",title] forKey:[NSString stringWithString:@"title"]];

// the boundary string : a random string, that will not repeat in post data, to separate post data fields.
NSString *BoundaryConstant = [NSString stringWithString:@"----------V2ymHFg03ehbqgZCaKO6jy"];

// string constant for the post parameter 'file'. My server uses this name: `file`. Your's may differ 
NSString* FileParamConstant = [NSString stringWithString:@"file"];

// the server url to which the image (or the media) is uploaded. Use your server url here
NSURL* requestURL = [NSURL URLWithString:@""]; 

// create request
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];                                    
[request setCachePolicy:NSURLRequestReloadIgnoringLocalCacheData];
[request setHTTPShouldHandleCookies:NO];
[request setTimeoutInterval:30];
[request setHTTPMethod:@"POST"];

// set Content-Type in HTTP header
NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@", BoundaryConstant];
[request setValue:contentType forHTTPHeaderField: @"Content-Type"];

// post body
NSMutableData *body = [NSMutableData data];

// add params (all params are strings)
for (NSString *param in _params) {
    [body appendData:[[NSString stringWithFormat:@"--%@\r\n", BoundaryConstant] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"%@\"\r\n\r\n", param] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[[NSString stringWithFormat:@"%@\r\n", [_params objectForKey:param]] dataUsingEncoding:NSUTF8StringEncoding]];
}

// add image data
NSData *imageData = UIImageJPEGRepresentation(imageToPost, 1.0);
if (imageData) {
    [body appendData:[[NSString stringWithFormat:@"--%@\r\n", BoundaryConstant] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"%@\"; filename=\"image.jpg\"\r\n", FileParamConstant] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[[NSString stringWithString:@"Content-Type: image/jpeg\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:imageData];
    [body appendData:[[NSString stringWithFormat:@"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
}

[body appendData:[[NSString stringWithFormat:@"--%@--\r\n", BoundaryConstant] dataUsingEncoding:NSUTF8StringEncoding]];

// setting the body of the post to the reqeust
[request setHTTPBody:body];

// set the content-length
NSString *postLength = [NSString stringWithFormat:@"%lu",(unsigned long) [body length]];
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];

// set URL
[request setURL:requestURL];

Untuk orang-orang yang merujuk kode ini: "BoundaryConstant" pada dasarnya adalah variabel "batas" yang pada dasarnya adalah acak (NSString *), "FileParamConstant" pada dasarnya adalah "nama file.jpg" Anda.

Saya mencoba kode ini tetapi saya pikir itu meleset dari instruksi untuk benar-benar meluncurkan permintaan. Bisakah seseorang memberi tahu saya apa dalam kasus ini?

@Gannicus, jangan menyeretnya terlalu banyak, itu akan menjadi seperti ini: [NSURLConnection sendAsynchronousRequest: antrian permintaan: [NSOperationQueue mainQueue] completeHandler: ^ (NSURLResponse * response, NSData * data, NSError * connectionError) {}];

Jawaban XJones bekerja seperti pesona.

Tapi dia tidak menyebutkan / mendeklarasikan variabel _params, BoundaryConstantdan requestURL. Jadi, saya berpikir untuk memposting bagian itu sebagai add-on pada postingannya, sehingga dapat membantu orang lain di masa depan.

// Dictionary that holds post parameters. You can set your post parameters that your server accepts or programmed to accept.
NSMutableDictionary* _params = [[NSMutableDictionary alloc] init];
[_params setObject:[NSString stringWithString:@"1.0"] forKey:[NSString stringWithString:@"ver"]];
[_params setObject:[NSString stringWithString:@"en"] forKey:[NSString stringWithString:@"lan"]];
[_params setObject:[NSString stringWithFormat:@"%d", userId] forKey:[NSString stringWithString:@"userId"]];
[_params setObject:[NSString stringWithFormat:@"%@",title] forKey:[NSString stringWithString:@"title"]];

// the boundary string : a random string, that will not repeat in post data, to separate post data fields.
NSString *BoundaryConstant = [NSString stringWithString:@"----------V2ymHFg03ehbqgZCaKO6jy"];

// string constant for the post parameter 'file'. My server uses this name: `file`. Your's may differ 
NSString* FileParamConstant = [NSString stringWithString:@"file"];

// the server url to which the image (or the media) is uploaded. Use your server url here
NSURL* requestURL = [NSURL URLWithString:@""]; 

Seperti yang saya sebutkan sebelumnya, ini bukan jawaban dengan sendirinya, hanya tambahan untuk posting XJones .

saya mencoba ini tetapi saya (nsmutabledata) menjadi null pada akhir waktu setHTTPBody. apakah saya melewatkan sesuatu?

Gunakan AFNetworking; Letakkan parameter lain di kamus parameter dan tambahkan data gambar ke data formulir.

//Upload Image Using AFNetworking

-(BOOL)uploadImageAFNetworkingWithURL:(NSString *)path andImage:(UIImage *)image andImageNameWithExtension:(NSString *)strImageName andParamDict:(NSDictionary *)dictParam andKeyForUploadingImage:(NSString *)keyUplaodImg{

    NSData *imageData = UIImageJPEGRepresentation(image, 0.5);
    NSString *strError = EMPTY_STRING;

    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
     manager.requestSerializer = [AFJSONRequestSerializer serializer];
    [manager POST:path parameters:dictParam constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {

        [formData appendPartWithFileData:imageData name:keyUplaodImg fileName:strImageName mimeType:@"image/jpeg"];

    } success:^(AFHTTPRequestOperation *operation, id responseObject) {
        NSLog(@"success = %@", responseObject);
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        NSLog(@"error = %@", error);
        NSLog(@"Response = %@", operation);
        [strError stringByAppendingString:STR_ERR_MESSAGE];
    }];
    if(strError.length>0){
        return NO;
    }else{
        return YES;
    }

Berikut adalah pustaka kit jaringan saya yang serupa untuk mengunggah file sebagai bentuk multi bagian:

WebRequest *request = [[WebRequest alloc] initWithPath:@"...documents/create.json"];

// optional attributes
request.delegate = delegate;
request.notificationName = @"NotificationDocumentUploaded";
request.queue = myQueue;

NSMutableData *body = [NSMutableData data];
NSString *boundary = @"TeslaSchoolProjectFormBoundary";

[body appendPartName:@"document[name]" value:@"Test" boundary:boundary];
[body appendPartName:@"document[description]" value:@"This is a description" boundary:boundary];
[body appendPartName:@"document[category]" value:@"Drama" boundary:boundary];
...
[body appendPartName:@"commit" value:@"Save" boundary:boundary];
NSData *fileData = [[NSData alloc] initWithContentsOfURL:someFileURL];
[body appendPartFile:fileName name:@"document[file]" data:fileData mimeType:mimeType boundary:boundary];
[body appendData:[[NSString stringWithFormat:@"--%@--\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];

[request setHTTPBody:body];

NSString *bodyLength = [NSString stringWithFormat:@"%lu",(unsigned long)[body length]];
[request addValue:bodyLength forHTTPHeaderField:@"Content-Length"];
[request setValue:[NSString stringWithFormat:@"multipart/form-data; charset=utf-8; boundary=%@", boundary] forHTTPHeaderField:@"Content-Type"];


// optional values
[request addValue:@"gzip,deflate,sdch" forHTTPHeaderField:@"Accept-Encoding"];
[request addValue:@"max-age=0" forHTTPHeaderField:@"Cache-Control"];
[request addValue:@"text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8" forHTTPHeaderField:@"Accept"];
[request addValue:@"en-US,en;q=0.8,hr;q=0.6,it;q=0.4,sk;q=0.2,sl;q=0.2,sr;q=0.2" forHTTPHeaderField:@"Accept-Language"];


[request setHTTPMethod:@"POST"];
[WebRequestProcessor process:request];

Gunakan delegasi untuk memberi tahu tentang kemajuan pengunggahan.

Gunakan notificationName untuk memberi tahu ketika permintaan telah selesai.

Gunakan antrian untuk menambahkan permintaan ini ke dalam antrian operasi Anda sehingga akan diproses pada waktu yang tepat.

Ini adalah versi Swift. Perhatikan bahwa jika Anda tidak ingin mengirim data formulir, tetap penting untuk mengirim batas formulir yang kosong. Flask secara khusus mengharapkan data formulir diikuti oleh data file dan tidak akan terisi request.filestanpa batas pertama.

  let composedData = NSMutableData()

  // Set content type header
  let BoundaryConstant = "--------------------------3d74a90a3bfb8696"
  let contentType = "multipart/form-data; boundary=\(BoundaryConstant)"
  request.setValue(contentType, forHTTPHeaderField: "Content-Type")

  // Empty form boundary
  composedData.appendData("--\(BoundaryConstant)\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)

  // Build multipart form to send image
  composedData.appendData("--\(BoundaryConstant)\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
  composedData.appendData("Content-Disposition: form-data; name=\"file\"; filename=\"image.jpg\"\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
  composedData.appendData("Content-Type: image/jpeg\r\n\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
  composedData.appendData(rawData!)
  composedData.appendData("\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
  composedData.appendData("--\(BoundaryConstant)--\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)

  request.HTTPBody = composedData

  // Get content length
  let length = "\(composedData.length)"
  request.setValue(length, forHTTPHeaderField: "Content-Length")

Unggah gambar dengan data formulir menggunakan kelas NSURLConnection di Swift 2.2 :

    func uploadImage(){
        let imageData = UIImagePNGRepresentation(UIImage(named: "dexter.jpg")!)

        if imageData != nil{
            let str = "https://staging.mywebsite.com/V2.9/uploadfile"
            let request = NSMutableURLRequest(URL: NSURL(string:str)!)
            request.HTTPMethod = "POST"

            let boundary = NSString(format: "---------------------------14737809831466499882746641449")

            let contentType = NSString(format: "multipart/form-data; boundary=%@",boundary)
            request.addValue(contentType as String, forHTTPHeaderField: "Content-Type")

            let body = NSMutableData()

            // append image data to body
            body.appendData(NSString(format: "\r\n--%@\r\n", boundary).dataUsingEncoding(NSUTF8StringEncoding)!)
            body.appendData(NSString(format:"Content-Disposition: form-data; name=\"file\"; filename=\"img.jpg\"\\r\n").dataUsingEncoding(NSUTF8StringEncoding)!)
            body.appendData(NSString(format: "Content-Type: application/octet-stream\r\n\r\n").dataUsingEncoding(NSUTF8StringEncoding)!)
            body.appendData(imageData!)
            body.appendData(NSString(format: "\r\n--%@\r\n", boundary).dataUsingEncoding(NSUTF8StringEncoding)!)

            request.HTTPBody = body

            do {
                let returnData = try NSURLConnection.sendSynchronousRequest(request, returningResponse: nil)
                let returnString = NSString(data: returnData, encoding: NSUTF8StringEncoding)
                print("returnString = \(returnString!)")
            }
            catch let  error as NSError {
                print(error.description)
            }
        }
    }

Catatan: Selalu gunakan sendAsynchronousRequestmetode alih-alih sendSynchronousRequestuntuk mengunggah / mengunduh data untuk menghindari pemblokiran utas utama. Di sini saya menggunakan sendSynchronousRequest untuk tujuan pengujian saja.

Saya dapat menunjukkan kepada Anda contoh mengunggah file .txt ke server dengan NSMutableURLRequestdan NSURLSessionUploadTaskdengan bantuan skrip php .

-(void)uploadFileToServer : (NSString *) filePath
{
NSMutableURLRequest* request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"http://YourURL.com/YourphpScript.php"]];
[request setHTTPMethod:@"POST"]; 
[request addValue:@"File Name" forHTTPHeaderField:@"FileName"];
NSURLSessionConfiguration *defaultConfigObject = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURLSession *defaultSession = [NSURLSession sessionWithConfiguration:defaultConfigObject];

NSURLSessionUploadTask* uploadTask = [defaultSession uploadTaskWithRequest:request fromFile:[NSURL URLWithString:filePath] completionHandler:^(NSData *data, NSURLResponse *response, NSError *error)
                                      {
                                          NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse *) response;
                                          if (error || [httpResponse statusCode]!=202)
                                          {

                                              //Error
                                          }
                                          else
                                          {
                                             //Success
                                          }
                                          [defaultSession invalidateAndCancel];
                                      }];
