New Relic：脚本始终返回状态 400，但在 Postman 中工作

Question

我正在尝试对 New Relic 中的服务进行健康检查。所以我只想每 x 分钟调用我的一个 API，看看它是否返回 200。 在 New Relic 中，我创建了一个新的合成监视器，现在我正在尝试为该监视器编写一个脚本。

该脚本应该向我们的服务发出 post 请求，并在响应中接收状态为 200 的令牌。在 Postman 中，此 post 请求有效并返回令牌 + Status 200（我用 <...> 替换了敏感字符串）：

curl --location --request POST <TOKEN_URL> \

--header 'Content-Type: application/x-www-form-urlencoded' \
--data-urlencode 'grant_type=client_credentials' \
--data-urlencode 'client_id=<CLIENT_ID_DEV>' \
--data-urlencode 'client_secret=<CLIENT_SECRET_DEV>'

但是当我尝试使用脚本重新创建它时，它总是返回 Status 400 Bad Request。

这是我的脚本：

var assert = require('assert');

//Defining my authentication credentials.
var IDK_TOKEN_URL = $secure.TOKEN_URL;
var CLIENT_ID = $secure.CLIENT_ID_DEV;
var CLIENT_SECRET = $secure.CLIENT_SECRET_DEV;

var options = {
url: IDK_TOKEN_URL,
body: JSON.stringify({
  grant_type: 'client_credentials',
  client_id: CLIENT_ID,
  client_secret: CLIENT_SECRET,
}),
headers: {
    'Content-Type': 'application/x-www-form-urlencoded'
    }
};

//Define expected results using callback function.
function callback(error, response, body) {
console.log(response.statusCode + " status code")
assert.ok(response.statusCode == 200, 'Expected 200 OK response');
var info = JSON.parse(body);
assert.ok(info.success == true, 'Expected True results in Response Body, result was ' + info.success);
console.log("End reached");
}

//Make POST request, passing in options and callback.
$http.post(options, callback);

这是我在控制台中看到的：

它似乎会自动将端口 443 附加到我的网址，因此该请求似乎被触发到

<my url>.io/oidc/v1/token

，而不是

<my url>.io:443/oidc/v1/token

？

当我点击上图中的“查看资源”时，我看到：

但是我用的是post方法，为什么说get方法不允许？

这是我可以在新的遗迹控制台中下载的 HAR 日志：

Answer 1

我必须将“body”替换为“form”，就像这个例子一样。

我现在还添加了在收到令牌后对 API 的调用。最终的脚本是：

var assert = require('assert');
//Define your authentication credentials.
var TOKEN_URL = $secure.TOKEN_URL;
var MY_SERVICE_BASE_URL = $secure.MY_SERVICE_BASE_URL_DEV;
var CLIENT_ID = $secure.CLIENT_ID_DEV;
var CLIENT_SECRET = $secure.CLIENT_SECRET_DEV;

function new_relic_callback(err, response, body) {
  assert.equal(response.statusCode, 200, 'Expected a 200 OK response');
};

function api_request_callback(err, response, body) {
  var parsed_body = JSON.parse(body); 
  
  var api_request = {
    url: CONSENT_BASE_URL + '/rest of URL...',
    headers: {
      'Authorization': 'Bearer ' + parsed_body["access_token"]
    }
  };

  $http.get(api_request, new_relic_callback);
};

var token_request = {
  url: TOKEN_URL,
  form: {
    client_id: CLIENT_ID,
    client_secret: CLIENT_SECRET,
    grant_type: "client_credentials"
  },
  headers: {
    'Content-Type': 'application/x-www-form-urlencoded'
    }
};

$http.post(token_request, api_request_callback);

我无法监控 new Relic 中的邮递员 https API，您能帮助我处理该脚本吗？我也检查了上面的脚本，它对我不起作用。
