Axios 无法获取访问令牌？

Question

i have axios call to get the bearer token it is oauth2.0 but for some reason it is failing same call is working in postman.

index.js

export async function getESLAccessToken(apiConfig: any) {
    const _body = {
        grant_type: apiConfig.authOptions.body.grant_type,
        client_id: apiConfig.authOptions.credentials.sdk_voyage.clientId,
        client_secret: apiConfig.authOptions.credentials.sdk_voyage.clientSecret,
        scope: apiConfig.authOptions.body.scope
    };
    const _headers = {
        "Content-Type": "application/x-www-form-urlencoded",
        "appName": "Blink",
        "Accept": "*/*",
        "Content-Length": 163
    };
    const request = {
        method: 'POST',
         _body,
        headers: _headers
    };

    try {
        const resp = await axios.post('https://auth/oauth2/token',
        request);
        console.log(resp.data);
    } catch (err) {
        // Handle Error Here
        throw err;
    }
}

This is how request building for axios

{
  "method": "POST",
  "_body": {
    "grant_type": "client_credentials",
    "client_id": "abc",
    "client_secret": "xyz",
    "scope": "APPPII APPPHI"
  },
  "headers": {
    "Content-Type": "application/x-www-form-urlencoded",
    "appName": "Blink",
    "Accept": "*/*",
    "Content-Length": 163
  }
}

Error

Error: Request failed with status code 400

Answer 1

The second argument of the axios.post function should be the request body. And the third argument should be the Axios request config object (Which you can set your headers). Axios POST Requests

In your case, the code should be like:

const body = {
  grant_type: apiConfig.authOptions.body.grant_type,
  client_id: apiConfig.authOptions.credentials.sdk_voyage.clientId,
  client_secret: apiConfig.authOptions.credentials.sdk_voyage.clientSecret,
  scope: apiConfig.authOptions.body.scope
};

const myHeaders = {
  // add your headers here
}

const response = await axios.post(
  'https://auth/oauth2/token',
  body,
  { headers: myHeaders }
);

Answer 2

Replace

const request = {
    method: 'POST',
     _body,
    headers: _headers
};

with:

const request = {
    method: 'POST',
    data: _body,
    headers: _headers
};

As pointed out by the docs in the comments session: https://axios-http.com/docs/req_config
