使用 `request` 请求成功但使用 `axios` 失败

我有这个微软图形身份验证代码，使用

axios

request

const axios = require('axios')
const request = require("request");
const FormData = require('form-data');

const data = FormData()
data.append('client_id', XXXXXXXXXXX),
data.append('client_secret', XXXXXXXXX),
data.append('scope', "/.default"),
data.append('grant_type', 'client_credentials')

const requestParams = {
    client_id: logins.activedirectory.clientID,
    client_secret: logins.activedirectory.clientSecret,
    scope: "/.default",
    grant_type: "client_credentials",
};

const endpoint = "/" + XXXXXXXX + "/oauth2/v2.0/token";

///////// AXIOS //////////
axios({
    method: 'post',
    url: endpoint,
    data: data,
    headers: {'Content-Type': 'application/x-www-form-urlencoded' }
})
.then(function (response) {
    console.log(response);
})
.catch(function (response) {
    console.log(response);
});

///////// REQUEST /////////
request.post({ url:endpoint, form: requestParams }, function (err, response, body) {
    if (err) {
        console.log(err);
    } else {
        console.log(body);
    }
});

这是一个老问题，但我最近遇到了类似的问题，经过一番研究后解决了。客户端凭据 API 需要一个 url_encoded 正文。 这记录在这里：https://learn.microsoft/en-us/graph/auth-v2-service。

form-data

const postData = {
  tenant: "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
  client_id: "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
  scope: "https://graph.microsoft/.default",
  client_secret: "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
  grant_type: "client_credentials",
};

和 stringifed 和 urlencoded

tenant=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
&client_id=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
&scope=https%3A%2F%2Fgraph.microsoft%2F.default
&client_secret=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
&grant_type=client_credentials

qs 包很容易做到这一点。参考这篇文章https://askfiqri/how-to-get-an-access-token-for-microsoft-graph-api-using-node-js-258723f29cc6

完整的解决方案是：

    const axios = require("axios");
    const qs = require("qs");
    
    const postData = {
      tenant: "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
      client_id: "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
      scope: "https://graph.microsoft/.default",
      client_secret: "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
      grant_type: "client_credentials",
    };
    
   const OAUTH_URL = `https://login.microsoftonline/${postData.tenant}/oauth2/v2.0/token`;
   let response = await axios({
        method: "post",
        url: OAUTH_URL,
        data: qs.stringify(postData),
        headers: { "Content-Type": "application/x-www-form-urlencoded" },
   });

注意：此 api 调用必须从服务器或通过代理完成（在我的例子中是通过 APIGateway 的 AWS Lambda）。由于 CORS 错误，axios 调用将无法从浏览器运行，这显然无法规避。
