ios – obj-c AFNetworking 2.0 POST请求不起作用

希望通过使用AFNetworking 2.0将一些数据(字符串和文件)发送到服务器.不知何故,POST请求的数据(对于一个forumlar)是不正确的,它看起来像是请求上的编码/序列化丢失.由于服务器无法使用我上传的数据.

如何将编码/序列化设置为请求？

我假设URL格式参数编码,必须设置.文档说明

[[AFHTTPRequestSerializer serializer] requestWithMethod:@"POST" URLString:URLString parameters:parameters];

我试图这样做,但我不知道如何做到正确.通过以下Xcode通过警告：

manager.requestSerializer = [[AFHTTPRequestSerializer serializer] requestWithMethod:@"POST" URLString:URLString parameters:parameters];
