Question

我一直试图让PHP应用程序连接到Instapaper的Xauth服务，但是对于我来说，我无法让它运行起来。我一直得到一个＆＃34; 403：无效的签名。＆＃34;错误。

错误说我的签名基本字符串不是它所期望的，但是当我将我构建的签名基本字符串与他们所期望的内容进行比较时，它们完全相同（删除了敏感信息）：
我的签名基本字符串：

POST＆安培; HTTPS％3A％2F％2Fwww.instapaper.com％2Fapi％2F1％2Foauth％2Faccess_token＆安培; oauth_callback％3DMy_URL％26oauth_consumer_key％3DCONSUMER_KEY％26oauth_nonce％3Dfe379af261aca07d890d2cfaa0f19ce0％26oauth_signature_method％3DHMAC-SHA1％26oauth_timestamp％3D1461898452％26oauth_version％3D1 0.0％26x_auth_mode％3Dclient_auth％26x_auth_password％3DPASSWORD％26x_auth_username％3DEXAMPLE％2540gmail.com

错误预期：

POST＆安培; HTTPS％3A％2F％2Fwww.instapaper.com％2Fapi％2F1％2Foauth％2Faccess_token＆安培; oauth_callback％3DMy_URL％26oauth_consumer_key％3DCONSUMER_KEY％26oauth_nonce％3Dfe379af261aca07d890d2cfaa0f19ce0％26oauth_signature_method％3DHMAC-SHA1％26oauth_timestamp％3D1461898452％26oauth_version％3D1 0.0％26x_auth_mode％3Dclient_auth％26x_auth_password％3DPASSWORD％26x_auth_username％3DEXAMPLE％2540gmail.com

我从https://github.com/mheap/Instapaper-XAuth-PHP取出了我的php库，但它已经过时了，所以我尝试修改它以使用当前的Instapaper API。我相信我正确生成了签名字符串，并遵循此处的说明：https://dev.twitter.com/oauth/overview/creating-signatures并在此处：http://oauthbible.com/

我不知道代码有什么问题，有人可以帮忙吗？
