afn怎么发送请求时可以将参数放在body里面吗////

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

                      parameters:(id)parameters

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

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

这个parameters是一个NSDictionary

NSMutableDictionary *dict = xxx;
dict setObject:参数1 forKey:参数1的名称

最后直接post:urlString parameters:dict success:xxx failure:xxx

这个就直接是放在body里面了

追问

我是这样写得,但是参数一直放不进去,请问

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

 具体该怎么放? 

参数不论是放dict,还是str,  都返回一样得结果 参数为空.  

后台说必须将参数放在body里面!  

将参数放在parameters:  不是直接拼接到url后面吗

追答

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以后, 写上这些东西
