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
