问题是我每次尝试检索access_token时都会收到401：Unauthorized：无效签名. (向下滚动代码,用注释缩进问题)

现在我的服务器被设置为三脚OAuth应用程序(as described fully here).这意味着将有3个端点：

1. / request_token(这个有效)

请求(GET参数)：

oauth_version : ...
oauth_nonce: ....
oauth_timestamp: ...
oauth_consumer_key: ...
oauth_signature_method: ...
oauth_signature: ...

响应：

oauth_token: .... (temporary)
oauth_token_secret: ....

2. / authorize(这个也有效 – >打开浏览器进行身份验证)

请求(GET参数)：

oauth_token: ....
oauth_callback: ....

响应

oauth_token: ....
oauth_verifier: ...

3. / access_token(这个不起作用)

请求(GET参数)

oauth_token: ....
oauth_verifier: ....
oauth_version : ...
oauth_nonce: ....
oauth_timestamp: ...
oauth_consumer_key: ...
oauth_signature_method: ...
oauth_signature: ...

响应：

oauth_token: .... (permanent)
oauth_secret: ....

尽管我以相同的方式设置了signatureBaseString并设置了密钥according to the guide,但最后一个不起作用

完整代码,包括其他2个电话(凌乱,我知道)

make it work,make it better,make it fast
