【Go HTTPClient包坑】
// An error is returned if there were too many redirects or if there 
// was an HTTP protocol error. A non-2xx response doesn't cause an 
// error. Any returned error will be of type *url.Error. The url.Error 
// value's Timeout method will report true if request timed out or was 
// canceled.
非200状态码并不会抛出Error，需要手动显示处理
