Question

我必须将包括图像在内的一些数据添加到服务器，并提供以下详细信息：

方法：POST 服务器网址：http://dev.aaaa.com/register

接头：关键价值观 App_id xxxxx App_key yyyyy enctype multipart / form-data

体：

关键值 data {“code”：“21187”，“fname”：“Manish”，“lname”：“Sharma”} image mypic.jpeg

朋友们请帮我在AFNetworking下用身体和标题形成请求。

感谢大家考虑这个问题并协助我

Answer 1

UIImage *image = //Your Image.

NSDictionary *params =@{@"data": @{@"code" : @"21187",
                                   @"fname" : @"Manish",
                                   @"lname" : @"lname"
                                  }
                        };


static AFHTTPRequestOperationManager *afPostManager = nil;

afPostManager = [[AFHTTPRequestOperationManager alloc] initWithBaseURL: [NSURL URLWithString:@"http://dev.aaaa.com"]];
[afPostManager.responseSerializer setAcceptableContentTypes:[NSSet setWithObject:@"application/json"]];

[afPostManager.requestSerializer setValue:@"xxxx" forHTTPHeaderField:@"app-id"];
[afPostManager.requestSerializer setValue:@"xxxx" forHTTPHeaderField:@"app-key"];
[afPostManager.requestSerializer setValue:@"multipart/form-data" forHTTPHeaderField:@"enctype"];

afPostManager.responseSerializer = [AFJSONResponseSerializer
                                    serializerWithReadingOptions:NSJSONReadingAllowFragments];


[afPostManager POST:@"register" parameters:params constructingBodyWithBlock:^(id<AFMultipartFormData>  _Nonnull formData) {

    NSData *imageData = UIImageJPEGRepresentation(image, 0.5);

    [formData appendPartWithFileData:imageData name:title fileName:@"mypic.jpg" mimeType:@"image/jpeg"];

} success:^(AFHTTPRequestOperation * _Nonnull operation, id  _Nonnull responseObject) {
    NSLog(@"success : %@",responseObject);

} failure:^(AFHTTPRequestOperation * _Nullable operation, NSError * _Nonnull error) {
    NSLog(@"failed : %@",error.localizedDescription);

}];

试试这个

NSDictionary *dataDict = <data to send>;
NSError *error = nil;

NSData *jsonData = [NSJSONSerialization dataWithJSONObject:dataDict options:NSJSONWritingPrettyPrinted error:&error];
NSString *jsonString = [NSString stringWithFormat:@"%@", [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding]];
NSLog(@“json = %@", jsonData);

NSURLSessionConfiguration *config = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURL *baseURL = [NSURL URLWithString:@“http://dev.aaaa.com/”];
NSLog(@“base URL = %@", baseURL);

AFHTTPSessionManager *sessionManager = [[AFHTTPSessionManager alloc] initWithBaseURL:baseURL sessionConfiguration:config];
[sessionManager.requestSerializer setTimeoutInterval:500.0];
sessionManager.requestSerializer = [AFJSONRequestSerializer serializer];

AFJSONResponseSerializer *responseSerializer = [AFJSONResponseSerializer serializerWithReadingOptions:NSJSONReadingAllowFragments];
sessionManager.responseSerializer = responseSerializer;

sessionManager.responseSerializer.acceptableContentTypes = [sessionManager.responseSerializer.acceptableContentTypes setByAddingObject:@"text/html"];

NSData *imageData = UIImageJPEGRepresentation(image, 0.5);

[sessionManager POST:@“register” parameters:dataDict constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {

    //-------- here append images as form data -------------------------

    [formData appendPartWithFileData:imageData name:@“image” fileName:@“myimage.jpg" mimeType:@"image/jpeg"];

} progress:^(NSProgress * _Nonnull uploadProgress) {

    progressBlock(uploadProgress);

} success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {

    successBlock(task, responseObject);

} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {

    faliureBlock(task, error);
}];

使用此功能可能会对您有所帮助。

我想通过AFNetworking将多部分数据添加到服务器
