swift开发网络篇 - post 请求
/**
所有网络请求,统一使用异步请求!
在今后的开发中,如果使用简单的get/head请求,可以用NSURLConnction异步方法
GET查/POST增/PUT改/DELETE删/HEAD
GET
1> URL
2> NSURLRequest
3> NSURLConnction 异步
POST
1> URL
2> NSMutableURLRequest
.httpMethod = @"POST";
str 从 firebug直接粘贴,或者自己写
变量名1=数值1&变量名2=数值2
.httpData = [str dataUsingEncoding:NSUTF8StringEncoding];
3> NSURLConnction 异步
