Wie ein Bild, Audiodaten zusammen mit einigen Parameter iOS veröffentlichen?

Question

Ich möchte Daten auf server mit einzigen URL, die Stimme data enthält, Bild und einige Textparameter mit NSMutableURLRequest und NSURLConnectiondelegate.

Vielen Dank im Voraus.

NSString *dvcToken = [[NSUserDefaults standardUserDefaults] valueForKey:@"deviceToken"]; 
NSMutableDictionary* _params = [[NSMutableDictionary alloc] init]; 
// parameters to send 
[_params setObject:@"842" forKey:@"office"]; 
[_params setObject:@"8442" forKey:@"client"]; 
[_params setObject:@"0" forKey:@"sub"]; 
[_params setObject:ofcrName forKey:@"name"]; 
[_params setObject:ofcrNo forKey:@"number"];// cin_out_datetime 
[_params setObject:curntDateTime forKey:@"cin_out_datetime"]; 
if(logIn){ 
    [_params setObject:@"I" forKey:@"process_type"]; 
    logIn = false; 
}else 
    [_params setObject:@"0" forKey:@"process_type"]; 
[_params setObject:dvcToken forKey:@"device_imei"]; 
[_params setObject:[[UIDevice currentDevice] name] forKey:@"device_name"]; 
//[_params setObject:audioData forKey:@"voice"]; 


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

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

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

// 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(officerImage, 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:[@"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]]; 

// my audio to post 
NSString *audioUrl = [NSString stringWithContentsOfURL:player.url]; 
NSData *audiodata; 
audiodata = [[NSData alloc] initWithContentsOfFile:audioUrl]; 
// add it to body 
[body appendData:audiodata]; 
[body appendData:[@"\r\n" dataUsingEncoding:NSUTF8StringEncoding]]; 

// final boundary 
[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:@"%d", [body length]]; 
[request setValue:postLength forHTTPHeaderField:@"Content-Length"]; 

// set URL 
[request setURL:requestURL];

können Sie diese Methode verwenden

-(NSMutableURLRequest *)setSingleFileMultipartRequestForUserID:(NSString *)userID serverUrl:(NSString *)url fileData:(NSData *)fileData fileName:(NSString *)fileName MIMEType:(NSString *)mimeType 
    { 
     NSMutableURLRequest *serverRequest = nil; 

     if(userID != nil || ![[NSString stringWithFormat:@"%@",userID] isEqualToString:@""] || url != nil || ![url isEqualToString:@""] || fileData.length >4) 
     { 
      NSURL *URL       = [NSURL URLWithString:url]; 
      NSString * lineEnd = @"\r\n"; 
      NSString * twoHyphens = @"--"; 
      NSString * boundary = [[NSUUID UUID] UUIDString]; 
      NSData *voiceData = nil; 
      voiceData = fileData; 
      if(voiceData != nil) 
      { 
       serverRequest = [[NSMutableURLRequest alloc] init]; 
       [serverRequest setTimeoutInterval:50]; 
       [serverRequest setURL:URL]; 
       [serverRequest setHTTPMethod:@"POST"]; 
       [serverRequest addValue:[NSString stringWithFormat:@"%@",userID] forHTTPHeaderField:@"user_id"]; 
       [serverRequest addValue:mimeType forHTTPHeaderField:@"mime-Type"]; 
       [serverRequest addValue:[NSString stringWithFormat:@"multipart/form-data; boundary=%@", boundary] forHTTPHeaderField:@"Content-Type"]; 
       NSMutableData *bodyData = [[NSMutableData alloc] init]; 
       [bodyData appendData:[[NSString stringWithFormat:@"%@%@%@",twoHyphens, boundary,lineEnd] dataUsingEncoding:NSUTF8StringEncoding]]; 
       [bodyData appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"uploaded_file\"; filename=%@ %@",[fileName stringByReplacingOccurrencesOfString:@" " withString:@"_"],lineEnd] dataUsingEncoding:NSUTF8StringEncoding]]; 
       [bodyData appendData:[[NSString stringWithFormat:@"%@", lineEnd] dataUsingEncoding:NSUTF8StringEncoding]]; 

       [bodyData appendData:voiceData]; 

       [bodyData appendData:[[NSString stringWithFormat:@"%@", lineEnd] dataUsingEncoding:NSUTF8StringEncoding]]; 
       [bodyData appendData:[[NSString stringWithFormat:@"%@%@%@%@",twoHyphens, boundary,twoHyphens, lineEnd] dataUsingEncoding:NSUTF8StringEncoding]]; 
       [serverRequest setHTTPBody:bodyData]; 
      } 
     } 
     return serverRequest; 
    } 

kehrt NSMutableURLRequest Objekt

dann für die Anforderung dieses Objekt verwenden

NSURLRequest * urlRequest2 = NSMutableURLRequest //requset get by above method 
    NSURLResponse * response2 = nil; 
      NSError * error2 = nil; 



    NSData * data2 = [NSURLConnection sendSynchronousRequest:urlRequest2 
                 returningResponse:&response2 
                    error:&error2]; 

if (error2 == nil) 
      { 

       NSDictionary *dict = [NSJSONSerialization JSONObjectWithData:data2 options:NSJSONReadingMutableContainers error:nil]; 
}
