如何在chrome扩展和Node服务器之间启用跨源AJAX请求？
[英]How can I enable cross-origin AJAX requests between my chrome extension and my Node server?
问题描述
In my background.js script, I'm making vanilla AJAX GET request using the XMLHttpRequest() object to my Node server (currently hosted on localhost ). 
在我的background.js脚本中，我正在使用XMLHttpRequest()对象向我的节点服务器（当前托管在localhost ）发出vanilla AJAX GET请求。 The Node server is using the npm package express to handle the GET request. Node服务器使用npm package express来处理GET请求。 However, background.js just returns the error: 但是， background.js只返回错误：
Access to XMLHttpRequest at 'localhost:80' from origin 'chrome-extension://jhccmehanjenpnjalilnihdmeignbcpn' has been blocked by CORS policy: Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, https.
Is it a permission I need to include in the manifest.json or something? 这是我需要包含在manifest.json的权限吗？ Thanks! 谢谢！
