javascript - vue uses native jsonp, how to make the jsonp returned in the background call the callback function?

Question

It’s like this, I use the native jsonp in vue, and then the jsonp returned in the background cannot always be called when calling callback! The following is part of my source code.

Answer 1

window.getData=function (data){
xxx logic
}

Answer 2

Obviously Vue has its own namespace, if you don’t use it explicitly

window.yourCallbackFunction=function(data){
//处理 data
}

Defining the global function in this way, jsonp obviously cannot successfully call the callback function.

To handle cross-domain requests, you can use webpack to configure the proxy to forward the request or use the node proxy service to forward the request
