Remove this:
删除这个：
headers: {
"Access-Control-Allow-Headers": "X-Requested-With",
"X-Requested-With": "XMLHttpRequest"
},
Access-Control-Allow-Headersis a responseheader, not a request header.
Access-Control-Allow-Headers是响应头，而不是请求头。
The server you are making the request to does not allow X-Requested-With.
您向其发出请求的服务器不允许X-Requested-With。
