无法检索访问令牌linkedin api

Question

我在申请connect with linkedin.我正在按照分步指南进行操作.为了验证用户身份,我把帮助从这个.

当用户单击该connect with linkedin按钮时,用户将进入linkedin登录页面.用户授予帐户访问权限后,用户将被重定向到:

https://www.linkedin.com/uas/oauth2/authorization?response_type=code&client_id=1ba8ogpm9e05&scope=r_basicprofile%20r_emailaddress&state=STATE&redirect_uri=http://127.0.0.1:8088/sandbox/linkedin/test.php

通过这个,我得到了授权码.并将其传递给以下网址

https://www.linkedin.com/uas/oauth2/accessToken?grant_type=authorization_code&code=AUTHORIZATION_CODE&redirect_uri=http://127.0.0.1:8088/sandbox/linkedin/final.php&client_id=1ba8ogpm9e05&client_secret=n7GN09I3F2L3IJD1

在这里,错误来了,即

"error":"invalid_request","error_description":"missing required parameters, includes an invalid parameter value, parameter more then once. : Unable to retrieve access token : appId or redirect uri does not match authorization code or authorization code expired"

我哪里错了？我仔细检查了我的api密钥和密钥.

https://www.linkedin.com/uas/oauth2/accessToken?grant_type=authorization_code&code=AUTHORIZATION_CODE&redirect_uri=http://127.0.0.1:8088/sandbox/linkedin/final.php&client_id=1ba8ogpm9e05&client_secret=n7GN09I3F2L3IJD1
https://www.linkedin.com/uas/oauth2/authorization?response_type=code&client_id=1ba8ogpm9e05&scope=r_basicprofile%20r_emailaddress&state=STATE&redirect_uri=http://127.0.0.1:8088/sandbox/linkedin/test.php

redirect_uri根据LinkedIn身份验证指南,这两者应该包含相同的内容:

参数: redirect_uri
说明:必需.与redirect_uri您在上一步中传递的相同.
可能的错误:

• 与redirect_uri授权代码生成期间使用的不同
• 传递了无效值
• 传递空值或空值
• 缺少参数
