javascript - 将响应 Request.post token 保存在变量中

Question

我只需要获取 API 中返回的 token 即可完成 URL。我需要获取response.body并保存在一个变量中以便之后使用。

我正在使用 Protractor 进行自动化测试，并打开一个 URL，我正在使用返回 token 的 API，以用作 URL 中的参数

describe('TEste API', function(){
    var Request = require('request');
    it("api Testing in protractor", async function (callback) {
        let tokenReturn = "empty";

        tokenReturn = Request.post({
            "headers": { "content-type": "application/x-www-form-urlencoded" }, 
            "url": "https://corpqa.sts.ford.com/adfs/oauth2/token",
            "form": {
                "grant_type":'client_credentials',
                "client_id":'ad9cdf61-e863-4606-a90a-cf7b7141234',
                "client_secret":'QmjeT5UZ0N1M0jOEcggrxgFzw-vrZY2UphAy21d5',
                "resource":'urn:age:pcf:sss:dev',
            }
        }, (error, response, body) => {
            if (error) {
                return console.dir(error); 
            }
            resp = JSON.parse(response.body);
            console.log("inside: " + resp.access_token);

            callback();
        });
        console.log("outside: www.example.com/?token=" + tokenReturn);
    });                                                                     
});//------------------------- end describe

在控制台中告诉我。

外部:

www.example.com/?token=[object Object]

内部:

我只是希望外部结果等于带有 token 的内部结果。 我做了一些更改，但结果更改为 UNDEFINED 而不是 OBJECT。

也许使用 promise ？

示例:

 function requestToServer(){
    return new Promise((resovle, reject) => {
        Request.post({
                "headers": { "content-type": "application/x-www-form-urlencoded" }, 
                "url": "https://corpqa.sts.ford.com/adfs/oauth2/token",
                "form": {
                    "grant_type":'client_credentials',
                    "client_id":'ad9cdf61-e863-4606-a90a-cf7b7141234',
                    "client_secret":'QmjeT5UZ0N1M0jOEcggrxgFzw-vrZY2UphAy21d5',
                    "resource":'urn:age:pcf:sss:dev',
                }
            }, (error, response, body) => {
            if (error) {
                return console.dir(error); 
            }
            resp = JSON.parse(response.body);
            console.log("inside: " + resp.access_token);
            resovle(resp.access_token);
            callback();
        });
    });
 }

 describe('TEste API', function(){
        var Request = require('request');
        it("api Testing in protractor", async function (callback) {

            let tokenReturn = await requestToServer();
            console.log("outside: www.example.com/?token=" + tokenReturn);
        });                                                                     
    });//------------------------- end describe
