AFN3.0设置请求头Header

默认的请求头是这样的

{      "Content-Length" = 1301;      "Content-Type" = "text/html;charset=UTF-8";      Date = "Mon, 24 July 2017 10:53:06 GMT";      Server = "Apache-Coyote/1.1";}

还可以使用花瓶Charles抓包看一下请求头

设置请求头如下：

//设置请求内容的类型[manager.requestSerializer setValue:@"application/json;charset=utf-8" forHTTPHeaderField:@"Content-Type"];//设置请求内容的长度[manager.requestSerializer setValue:[NSString stringWithFormat:@"%ld", (unsigned long)[jsonStr length]] forHTTPHeaderField:@"Content-Length"];//设置请求的编码类型[manager.requestSerializer setValue:@"gzip" forHTTPHeaderField:@"Content-Encoding"];
