我正在尝试使用Google Apps脚本中的OAuth访问StackExchange API。我正在使用this library

当我拨打以下电话时,我一开始没有访问权限(这是预期的)。我登录的授权URL是:

https://stackoverflow.com/oauth?client_id=14205&response_type=code&redirect_uri={URI}&state={STATE}&scope=read_inbox 

将autorizationURL粘贴到浏览器中,我得到的页面显示为:

"Error: Token response not valid JSON: SyntaxError: Unexpected token: a (line 532, file "Service", project "OAuth2")"

我从Apps脚本运行的内容:

function getMentions() {
   var service = getStackExchangeService_();
   Logger.log(service.hasAccess());
   if (service.hasAccess()) {

     //get token and call API
   }
   else {
   Logger.log("App has no access yet.");

   // open this url to gain authorization from Stack Exchange
   var authorizationUrl = service.getAuthorizationUrl();

   Logger.log("Open the following URL and re-run the script: %s",
     authorizationUrl);
   }
 }

我的Oauth.gs页面:

function getStackExchangeService_() {
  var CLIENT_ID = PropertiesService.getScriptProperties().getProperty('SE_CLIENT_ID');
  var CLIENT_SECRET = PropertiesService.getScriptProperties().getProperty('SE_CLIENT_SECRET');

  return OAuth2.createService('StackExchange')
  .setAuthorizationBaseUrl('https://stackoverflow.com/oauth')
  .setTokenUrl('https://stackoverflow.com/oauth/access_token')
  .setClientId(CLIENT_ID)
  .setClientSecret(CLIENT_SECRET)
  .setCallbackFunction('authCallbackSE')
  .setPropertyStore(PropertiesService.getUserProperties())
  .setRedirectUri('https://script.google.com/macros/d/{SCRIPT ID}/usercallback')
  .setScope('read_inbox');
}

function authCallbackSE(request) {
  var SEService = getStackExchangeService_();
  var isAuthorized = SEService.handleCallback(request);
  if (isAuthorized) {
    return HtmlService.createHtmlOutput('Success! You can close this tab.');
  } else {
    return HtmlService.createHtmlOutput('Denied. You can close this tab');
  }
}

不清楚我要去哪里,但是我认为当我输入authorizationURL时,应该将我重定向到授权页面。谢谢!

答案 0 :(得分:1)

问题:

Stackexchange API,默认情况下以application/x-www-form-urlencoded的形式发送访问令牌,默认情况下,OAuth2库的tokenFormat需要JSON。

解决方案:

  • 通过将tokenUrl设置为https://stackoverflow.com/oauth/access_token/json

  • 显式请求JSON的api
  • 在OAuth2库中明确设置tokenFormat以形成使用setTokenFormat(TOKEN_FORMAT.FORM_URL_ENCODED)

  • 编码的网址
