multipart/Iphone中混合应用

Question

我目前正在尝试在iphone应用程序中发送多部分/混合请求，但服务始终返回http状态代码500.我无权访问web服务的源代码。在Android的注册服务被称为像：

HttpPost httpost = new HttpPost(PlayerUrl.REGISTER_URL); 
    httpost.setHeader("Content-Type", "multipart/mixed"); 
    MultipartEntity entity = new MultipartEntity(); 

    String jsonData = "{\"firstName\":\"abc\",\"lastName\":\"xyz\",\"email\":\"abc@xyz.com\",\"password\":\"abc\",\"inviteType\":\"1\"}"; 

    StringBody jsonBean = new StringBody(jsonData, "application/json", null); 

    entity.addPart("user", jsonBean); 
    entity.addPart("image", new FileBody(new File(
    "/data/face.png"), "face.png", 
    "application/octet-stream", null)); 

    httpost.setEntity(entity); 

    HttpResponse response = client.execute(httpost); 
    System.out.println(response); 

但是，如何做到这一点在iphone我不知道。我搜索了整整一天，无法实现任何目标。目前，我有以下代码：

request = [[NSMutableURLRequest alloc] init]; 
    [request setURL:[NSURL URLWithString:url]]; 
    [request setHTTPMethod:method]; 

    //build body   
    NSMutableData *bodyForRequest = [NSMutableData data]; 

    //NSString *jsonData = [NSString stringWithFormat:@"%@", dataForJson]; 

    [request setHTTPMethod:@"POST"]; 
    NSString *boundary = @"91473780983146649988274664144"; 
    NSString *contentType = [NSString stringWithFormat:@"multipart/mixed; boundary=%@",boundary]; 
    [request addValue:contentType forHTTPHeaderField: @"Content-Type"]; 
    [request addValue:@"1.0" forHTTPHeaderField: @"MIME-Version"]; 

    [bodyForRequest appendData:[[NSString stringWithFormat:@"If you can see this MIME than your client doesn't accept MIME types!\r\n--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 



    [bodyForRequest appendData:[@"Content-Type: application/json;name = \"user\"\r\n" dataUsingEncoding:NSUTF8StringEncoding]]; 
    [bodyForRequest appendData:[@"Content-Transfer-Encoding: 7bit\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]]; 
    //[bodyForRequest appendData:[@"Content-ID: user\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]]; 
    //[bodyForRequest appendData:[[NSString stringWithFormat:@"Content-Disposition: name=\"user\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; 



    [bodyForRequest appendData:dataForJson]; 

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


    [bodyForRequest appendData:[@"Content-Type: image/jpg; name=\"image\"\r\n" dataUsingEncoding:NSUTF8StringEncoding]]; 
    [bodyForRequest appendData:[@"Content-Transfer-Encoding: base64\r\n" dataUsingEncoding:NSUTF8StringEncoding]]; 
    //[bodyForRequest appendData:[@"Content-ID: image\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]]; 
    NSString *str=[NSString stringWithFormat:@"Content-Disposition: attachment ;file=\"image.jpg\";\r\n\r\n"]; 

    [bodyForRequest appendData:[[NSString stringWithString:str] dataUsingEncoding:NSUTF8StringEncoding]]; 

    [bodyForRequest appendData:[NSData dataWithData:dataForImage]]; 


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


     [request setHTTPBody:bodyForRequest]; 

    // save request start time 
    requestStartTime = [CNUtility currentTimeInMilliseconds]; 

    // _connection the request now 
    NSLog(@"%@...request...%@",self,request); 
    _connection = [[NSURLConnection alloc] initWithRequest:request delegate:self]; 
    [_connection start]; 

我的要求是与个人资料图片一起发送JSON数据到服务器，请帮我出或请不要认为我的东西，可以帮助我。

此外，我不允许使用ASI，所以如果有其他事情请告诉我。

尝试使用AFNetworking，使您的生活更轻松，你的代码会看起来像与你有关的为你大胆

AFHTTPClient *httpClient  = [AFHTTPClient clientWithBaseURL:[NSURL URLWithString:[NSString stringWithFormat:@"%@", kUrl]]]; 

重要组成部分，这个重要的部分 - 启动

NSMutableURLRequest *afRequest = [httpClient multipartFormRequestWithMethod:@"POST" 
                     path:[NSString stringWithFormat:@"link?access_token=%@", kAPIToken] 
            parameters:nil constructingBodyWithBlock:^(id <AFMultipartFormData>formData) 
            { 
             [formData appendPartWithFileData:videoData name:@"link[data]" fileName:@"filename.mov" mimeType:@"video/quicktime"]; 

             NSString *tagStr = @"#partytrain"; 
             NSData *tagData = [tagStr dataUsingEncoding:NSUTF8StringEncoding]; 
             [formData appendPartWithFormData:tagData name:@"link[text]"]; 
            }]; 

AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:afRequest]; 

[operation setUploadProgressBlock:^(NSUInteger bytesWritten,long long totalBytesWritten,long long totalBytesExpectedToWrite) 
{ 
    //use a progress indicator here 
    NSLog(@"Sent %lld of %lld bytes", totalBytesWritten, totalBytesExpectedToWrite); 
}]; 

[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) { 
    NSLog(@"Success"); 
    [picker dismissViewControllerAnimated:YES completion:nil]; 
} 
            failure:^(AFHTTPRequestOperation *operation, NSError *error) {NSLog(@"error: %@", operation.responseString);}]; 

[operation start];
