小编use*_*343的帖子

我有一个返回JSON对象的URL,如下所示:

{
    "expires_in":5180976,
    "access_token":"AQXzQgKTpTSjs-qiBh30aMgm3_Kb53oIf-VA733BpAogVE5jpz3jujU65WJ1XXSvVm1xr2LslGLLCWTNV5Kd_8J1YUx26axkt1E-vsOdvUAgMFH1VJwtclAXdaxRxk5UtmCWeISB6rx6NtvDt7yohnaarpBJjHWMsWYtpNn6nD87n0syud0"
} 

我想得到access_token价值.那我怎么能通过PHP检索呢？

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.
