Question

我想进行一个包含URL参数和JSON正文的POST调用：

URL http://example.com/register?apikey=mykey
JSON { "field" : "value"}

如何在AFNNetworking的同时使用两个不同的序列化程序？这是我的代码，缺少URL参数：

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer = [AFJSONResponseSerializer serializer];
[manager POST:@"http://example.com/register" parameters:json success:^(AFHTTPRequestOperation *operation, id   responseObject) {

我制作了一个帖子方法

       protected void onActivityResult(int requestCode, int resultCode,  
       Intent data) {
        if (requestCode == 2) {


        Uri selectedImageUri = data.getData();
         FilePath=selectedImageUri.toString();



        FilePath=selectedImageUri.toString();
       //    uploadFile();
        if (resultCode == RESULT_OK){
            File imagefile = new File(FilePath);
            Log.e("FilePath",FilePath);
            String byteArrayStr = "";
            FileInputStream fis = null;
            try {
                fis = new FileInputStream(imagefile);

            } catch (FileNotFoundException e) {
                e.printStackTrace();
                Log.e("FIle Not found" +FilePath, "");
            }

            Bitmap bm = BitmapFactory.decodeStream(fis);
            ByteArrayOutputStream baos = new ByteArrayOutputStream();
            bm.compress(Bitmap.CompressFormat.PNG, 75, baos);

            byte[] data1 = baos.toByteArray();
            totalSize = data1.length;

            String strBase64 = Base64.encodeToString(data1, 
            0).toString();
            try {
                SoapObject request = new SoapObject(NAMESPACE, 
              "InsertFile");
                SoapSerializationEnvelope envelope = new
             SoapSerializationEnvelope(SoapEnvelope.VER11);              
                MarshalBase64 marshal = new MarshalBase64();
                marshal.register(envelope);
                envelope.dotNet = true;
                envelope.setOutputSoapObject(request);
                request.addProperty("FromUsername", 
                   LoginActivity.username.toString());
                request.addProperty("ToUsername",name[1]);
                request.addProperty("filetype", ".png");
                request.addProperty("f", data1);
                HttpTransportSE AndroidHttpTransportSE = new 
             HttpTransportSE(URL);
                try {
                    AndroidHttpTransportSE.call(NAMESPACE + 
                    "InsertFile",envelope);
                    // http://scm.org/UserDetails
                } catch (XmlPullParserException e) {
                    e.printStackTrace();
                }
                SoapPrimitive result = (SoapPrimitive) 
                     envelope.getResponse();

            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }else if(resultCode == RESULT_CANCELED){

            Toast.makeText(getApplicationContext(),"No file 
           }}}

+ (void)getDataWithObject:(NSDictionary *)object onAPI:(NSString *)apiName withController:(UIViewController*)controller
                         :(void(^)(BOOL success,id response,NSError *error))compilationHandler {


    controller = controller;
    [UIApplication sharedApplication].networkActivityIndicatorVisible = YES;

    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];

我相信没有自动的方法。但是，有一种简单的方法可以手动实现它：

- (NSMutableURLRequest *)someRequestWithBaseURL:(NSString *)baseUrl
                                          method:(NSString *)method
                                            path:(NSString *)path
                                      uriParameters:(NSDictionary *)uriParameters
                                  bodyParameters:(NSDictionary *)bodyParameters

NSURL *url = [NSURL URLWithString:path relativeToURL:[NSURL URLWithString:baseUrl]];

AFHTTPRequestSerializer *httpRequestSerializer = [AFJSONRequestSerializer serializerWithWritingOptions:0]

NSMutableDictionary *parameters = [NSMutableDictionary dictionaryWithDictionary:bodyParameters];

if ([httpRequestSerializer.HTTPMethodsEncodingParametersInURI containsObject:method]) {
    [parameters addEntriesFromDictionary:uriParameters];
} else {
    NSURLComponents *urlComponents = [NSURLComponents componentsWithURL:url resolvingAgainstBaseURL:YES];
    // For urlEncodedString, check http://stackoverflow.com/a/718480/856549
    urlComponents.percentEncodedQuery = [uriParameters urlEncodedString];
    url = [urlComponents URL];
}

NSError *error;
NSURLRequest *request = [httpRequestSerializer requestWithMethod:method
                                                       URLString:[url absoluteString]
                                                      parameters:parameters
                                                           error:&error];

在AFNetworking中使用URL参数和JSON主体进行POST
