新遗物：脚本总是 returns 状态 400 但在 Postman 中有效
New Relic: Script always returns Status 400 but works in Postman
我正在尝试对我在 New Relic 中的服务进行健康检查。所以我只想每隔 x 分钟调用一次我的 API，看看它是否 returns 200。
在 New Relic 中，我创建了一个新的 synthetic monitor，现在我正在尝试为该监视器编写一个 script。
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 请求有效并且 returns 令牌+ 状态 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>'
但是当我尝试用脚本重新创建它时，它总是 returns 状态 400 错误请求。
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：
它似乎自动将端口 443 附加到我的 url，所以请求似乎被触发到 <my url>.io:443/oidc/v1/token?
而不是 <my url>.io/oidc/v1/token
当我点击上图中的“查看资源”时，我看到：
但我使用的是 post 方法，为什么它说不允许使用 get 方法？
