Question

其实我有json参数

[dictionary setObject:_dateOfBirth.text  forKey:@"birth_date"];
    [dictionary setObject:_tfCountry.text  forKey:@"country"];
    [dictionary setObject:_tfEmail.text  forKey:@"email"];
    [dictionary setObject:@""  forKey:@"fromLogin"];
    [dictionary setObject:@1  forKey:@"gender"];
    [dictionary setObject:@"signup"  forKey:@"methodName"];
    [dictionary setObject:_tfContact.text  forKey:@"mobile"];
    [dictionary setObject:_tfName.text  forKey:@"name"];
    [dictionary setObject:_tfNickName.text  forKey:@"nickname"];
    [dictionary setObject:_tfPassword.text  forKey:@"password"];
    [dictionary setObject:_tfPinCode.text  forKey:@"pincode"];

还有一个Image，我必须将profile_pic设置为Key。现在我已将所有参数转换为数据，并将数据转换为此

NSData *jsonData = [NSJSONSerialization dataWithJSONObject:dictionary options:kNilOptions error:nil];

    // this is your service request url

    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"http://proteen2.inexture.com/webservice"]];

    // set the content as format

    [request setHTTPMethod:@"POST"];

    [request setHTTPBody: jsonData];

    // this is your response type

    [request setValue:@"application/json;charset=UTF-8" forHTTPHeaderField:@"content-type"];

    NSError *err;
    NSURLResponse *response;

    // send the synchronous connection

    NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&err];

    // here add your server response NSJSONSerialization

    NSArray *jsonArray = [NSJSONSerialization JSONObjectWithData:responseData options: NSJSONReadingMutableContainers error: &err];

它适用于Text，现在如何将Image附加到该参数，我只知道Multi Part但没有得到那个Point。请帮忙

你需要在这里管理很多东西，比如设置boundry追加图像数据等等。

您应该使用AFNetworking制作非常简单。从github下载并将库拖放到您的项目中并在您的课程中导入AFNetworking.h然后您可以执行类似的操作，

   NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer]multipartFormRequestWithMethod:@"POST" URLString:@"urlstring" parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData>  _Nonnull formData) {

    //Append image here for example;

    UIImage *img = tempImageView.image;
    NSData *imgData = UIImageJPEGRepresentation(img, 0.5);

    [formData appendPartWithFileData:imgData name:@"imagename/serversideparameter" fileName:@"imagename" mimeType:@"image/jpeg"];


} error:nil];

//Send this request to server. Something like,

NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];

AFURLSessionManager *manager = [[AFURLSessionManager alloc]initWithSessionConfiguration:configuration];

[[manager dataTaskWithRequest:request completionHandler:^(NSURLResponse * _Nonnull response, id  _Nullable responseObject, NSError * _Nullable error) {

    if (!error) {

        NSLog(@"success!!");

        NSLog(@"here is the response : %@",responseObject);
    }
    else{

        NSLog(@"Error Occured : %@",error.localizedDescription);
    }

}]resume];

您不应该使用NSUrlConnection，因为它现在已被弃用。最好使用NSUrlSession我通过AFNetworking回答过我。

如果您不想使用AFNetworking，请参阅this stackoverflow post。它在答案中一步一步地有很好的解释。

使用multiPart到URL发布图像
