ios开发-afn怎么发送请求时可以将参数放在body里面吗？

-(AFHTTPRequestOperation*)POST:(NSString*)URLStringparameters:(id)parameterssuccess:(void(^)(AFHTTPRequestOperation*operation,idresponseObject))successfailure:(void(^)(AFHTTPRequestOperation*operation,NSError*error))failure;这个parameters是一个NSDictionaryNSMutableDictionary*dict=xxx;dictsetObject:参数1forKey:参数1的名称最后直接post:urlStringparameters:dictsuccess:xxxfailure:xxx这个就直接是放在body里面了
