如何使用 JavaScript 获得 url json 响应的特定行

Question

I don't know about JavaScript, but I need to use just a little part of it. I have a url "http://my-url/api/auth/v1" that generates me the following json response:

{
    "token": {
        "token": "token-result-here",
        "result": null,
        "resultCode": "0",
        "requestId": "xx"
    },

I need a script that returns me just the result of "token". For example, when I call "token", it returns: "token-result-here". Could anyone help me with this code?

Answer 1

If

var response = {
"token": {
    "token": "token-result-here",
    "result": null,
    "resultCode": "0",
    "requestId": "xx"
}};

then use response.token.token to access "token-result-here"

Answer 2

You can save the request to the api to a variable let's say "apiResponse" and you can do this:

//parse the JSON
JSON.parse(apiResponse);
//access the JSON
let token = apiResponse.token.token;
