代号一-NetworManager

Question

每次调用请求时，我都会收到一个错误。当我用请求评论这行时。setPost（false），我从服务器得到一些响应。请解释出现此错误的原因。

线程"Thread-6"中的异常java.lang.IllegalStateException： Request方法（post/get）不能修改一个参数

必须在添加任何参数之前调用setPost。在所有addArgument调用之前调用它。实际错误是：

"Request method (post/get) can't be modified once arguments have been assigned to the request"

在目前的版本中，有一个拼写错误，它说的是一次而不是一次。
