网上找到一个方法：

大概就是，chrome安全策略的原因，chrome 禁止跨域策略(CORS policy) 

新建一个 禁止cors跨域相关的策略的 chrome，

1.桌面新建一个快捷方式：

"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --disable-web-security --disable-gpu --user-data-dir=~/chromeTemp

C:\Program Files (x86)\Google\Chrome\Application\chrome.exe ，为chrome的路径。

2.创建完成，使用该chrome访问即可。
