问题描述
我正在尝试访问Bing Ads API以获取我帐户的每日报告数据。
I am attempting to access the Bing Ads API to get daily report data for my accounts.
我有在此处概述的流程之后取得了部分成功：
I have had partial success following the process as outlined here:
https://msdn.microsoft.com/en-us/library/bing-ads-user-authentication-oauth-guide （v = msads.90）.aspx
https://msdn.microsoft.com/en-US/library/dn632721.aspx
使用Index.php，ClientCredentials.php，get_data.php和OAuth2Callback.php我能够运行，登录然后获取访问代码。该邮件连同代码为：
实施代码以使用访问令牌检索数据：
EwBwAn .... 。
我可以使用此代码发出请求并下载报告，但它的到期时间很短，我希望请求refresh_token，所以我不必每次都登录。
我通过curl使用client_id，grant_type = aurthorization_code，redirect_uri，client_secret和来自的代码发出请求前一步。然而，响应是通用的"服务器错误"。如果我尝试更改param的名称，例如我得到更多
有用的错误，例如{" error"：" invalid_request"，" error_description"："提供的请求必须包含'代码'输入参数。"}。
$
请求这个更长寿命的令牌时，我还需要注意一些其他元素吗？

Using Index.php, ClientCredentials.php, get_data.php and OAuth2Callback.php I am able to run, login and then get an access code. The message along with codes is:
Implement code to retrieve data with access token:
EwBwAn.....
I can use this code to make a request and download a report for example but it has a short expiration time and I wish to request the refresh_token so I do not have to login each time.
I make a request via curl with client_id, grant_type=aurthorization_code, redirect_uri, client_secret and code from previous step. However the response is a generic "server error". If I attempt to change the name of a param for example I get a more helpful error such as {"error":"invalid_request","error_description":"The provided request must include a 'code' input parameter."}.
Is there some other element I need to be aware of when requesting this longer life token?
推荐答案
// If the response contains an access_token element, it was successful.
// If not, an error occurred and the description will be displayed below
