afn怎麼發送請求時能夠將參數放在body裏面嗎////

- (AFHTTPRequestOperation *)POST:(NSString *)URLString

                      parameters:(id)parameters

                         success:(void (^)(AFHTTPRequestOperation *operation, id responseObject))success

                         failure:(void (^)(AFHTTPRequestOperation *operation, NSError *error))failure;

這個parameters是一個NSDictionary

NSMutableDictionary *dict = xxx;
dict setObject:參數1 forKey:參數1的名稱

最後直接post:urlString parameters:dict success:xxx failure:xxx

這個就直接是放在body裏面了

追問

我是這樣寫得,可是參數一直放不進去,請問

user={"password":"698d51a19d8a121ce581499d7b701668","email":"g@g.g","logintype":"1"}

 具體該怎麼放? 

參數不管是放dict,仍是str,  都返回同樣得結果 參數爲空.  

後臺說必須將參數放在body裏面!  

將參數放在parameters:  不是直接拼接到url後面嗎

manager.responseSerializer = [AFJSONResponseSerializer serializer];manager.responseSerializer.acceptableContentTypes = [manager.responseSerializer.acceptableContentTypes setByAddingObject:@"text/html"];    _requestManager.responseSerializer.acceptableContentTypes = [manager.responseSerializer.acceptableContentTypes setByAddingObject:@"text/xml"];初始化manager之後, 寫上這些東西
