<div style="color:rgb(70,70,70); font-family:simsun; font-size:14px; line-height:21px; background-color:rgb(188,211,229)">
  于是,开始各种Debug,绕了一大圈才发现是file_get_contents()函数的问题,由于不同的php版本对其的支持不同。

<div style="color:rgb(70,70,70); font-family:simsun; font-size:14px; line-height:21px; background-color:rgb(188,211,229)">
  没问题的php版本是5.4.7,

<div style="color:rgb(70,70,70); font-family:simsun; font-size:14px; line-height:21px; background-color:rgb(188,211,229)">
  直接返回相应的结果
