Google App 脚本中的 API Post 请求不起作用

Question

我设法通过 Postman 执行 API POST 请求，但一旦针对 Google App Script 进行修改，它就不起作用了。我认为这可能与格式有关body，我无法复制new URLSearchParams()GAS 中的对象（我相信我正在发送 JSON）。

谢谢。

邮递员（工作）-JavaScript 获取

var myHeaders = new Headers();
myHeaders.append("Content-Type", "application/x-www-form-urlencoded");

var urlencoded = new URLSearchParams();
urlencoded.append("client_id", "XXXX");
urlencoded.append("client_secret", "XXXX");
urlencoded.append("grant_type", "client_credentials");

var requestOptions = {
  method: 'POST',
  headers: myHeaders,
  body: urlencoded,
  redirect: 'follow'
};

fetch("https://apigateway.criteo.com/oauth2/token", requestOptions)
  .then(response => response.text())
  .then(result => console.log(result))
  .catch(error => console.log('error', error));

卷曲

curl --location --request POST 'https://apigateway.criteo.com/oauth2/token' \
--header 'Content-Type: application/x-www-form-urlencoded' \
--data-urlencode 'client_id=XXXX' \
--data-urlencode 'client_secret=XXXX' \
--data-urlencode 'grant_type=client_credentials'

我的 GAS 版本有问题:(

function getCostAU() {
  
  var myHeaders = {"Accept": "application/json",
                   "Content-Type": "application/x-www-form-urlencoded"};
  
  var myPayload = {"client_id" : "XXXX",
                   "client_secret" : "XXXX",
                   "grant_type" : "client_credentials"};
  
  var requestOptions = {
    method: 'POST',
    headers: myHeaders,
    body: myPayload,
    redirect: 'follow',
  };
    
  var url = "https://apigateway.criteo.com/oauth2/token";
  var result = JSON.parse(UrlFetchApp.fetch(url, requestOptions).getContentText());
  var access_token = result.access_token;
};

问题：

• body不是argument中的有效键options。你应该改用payload。

• redirect不是 options参数中的有效键

• 目前，URLSearchParams应用程序脚本不支持。

解决方案：

• 改成body​payload

• 重新创建该payload对象作为查询字符串。例如，payload:{x:1,y:2}应改为x=1&y=2.

片段：

• 用于查询参数的有效负载对象：

function objectToQueryParams(obj) {
  return (
    Object.entries(obj)
      .map(([k, v]) => `${encodeURIComponent(k)}=${encodeURIComponent(v)}`)
      .join('&')
  );
}

const myPayload = {"client_id" : "XXXX",
               "client_secret" : "XXXX",
               "grant_type" : "client_credentials"};
  
console.log(objectToQueryParams(myPayload));

• 有效的requestOption：

  const requestOptions = {
    /**@see https://developers.google.com/apps-script/reference/url-fetch/url-fetch-app#fetch(String,Object)*/
    method: 'POST',
    headers: myHeaders,
    payload: objectToQueryParams(myPayload),//modified
    //or just payload: myPayload will work as mentioned in the comments below
    //redirect: 'follow',//removed 
    followRedirects: true
  };

• 完整脚本：

  const requestOptions = {
    /**@see https://developers.google.com/apps-script/reference/url-fetch/url-fetch-app#fetch(String,Object)*/
    method: 'POST',
    headers: myHeaders,
    payload: objectToQueryParams(myPayload),//modified
    //or just payload: myPayload will work as mentioned in the comments below
    //redirect: 'follow',//removed 
    followRedirects: true
  };
