Hello gentlemans, I'm working on a client twitter that uses HTTP proxy in Java. I struggling with the OAuth request_token that returns me HTTP 401 Unauthorized.
Consumer key="3P1dah6urSdAo9voKDJDA" Consumer secret="kMYprvWb0UQ0L8oAin2dQJArUQfMcjuVSjOjyHzTv8E&" <-- I already added the "&" in the end of it twitterURL=[https://api.twitter.com/oauth/request_token] authorizationData=[OAuth realm="api.twitter.com", oauth_callback="oob", oauth_consumer_key="3P1dah6urSdAo9voKDJDA", oauth_nonce="901dc12600ac1cdbc082d57d4aef7bfc", oauth_signature_method="HMAC-SHA1", oaut h_timestamp="1276235403668", oauth_version="1.0", oauth_signature="5t6Fw%2BSs1JgkaaHjfOtGFpotWMw%3D"] basedata=[POST&https%3A%2F%2Fapi.twitter.com%2Foauth%2Frequest_token&oauth_callback%3Doob%26oauth_consumer_key%3D3P1dah6urSdAo9voKDJDA%26oauth_nonce%3D901dc12600ac1cdbc082d57d4aef7bfc%26oauth_signature_me thod%3DHMAC-SHA1%26oauth_timestamp%3D1276235403668%26oauth_version%3D1.0] And it returns the error: errorStream=[Failed to validate oauth signature and token] In order to check what I'm sending, I create a HttpListener and redirected the "api.twitter.com" to localhost:8000 and here is the header. Any suggestion is very welcome. POST /oauth/request_token HTTP/1.1 Authorization: OAuth realm="api.twitter.com", oauth_callback="oob", oauth_consumer_key="3P1dah6urSdAo9voKDJDA", oauth_nonce="2c449ca3c5a8637a8a9152d896c6d8bd", oauth_signature_method="HMAC-SHA1", oauth_timestamp="1276236145594", oauth_version="1.0", oauth_signature="y%2BstT1OQgJBRKLZ%2BR4K15TM4fGw%3D" User-Agent: Java/1.6.0_20 Host: localhost:8000 Accept: text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2 Connection: keep-alive Content-type: application/x-www-form-urlencoded Content-Length: 266 POST&http%3A%2F%2Flocalhost%3A8000%2Foauth%2Frequest_token&oauth_callback%3Doob%26oauth_consumer_key%3D3P1dah6urSdAo9voKDJDA%26oauth_nonce%3D2c449ca3c5a8637a8a9152d896c6d8bd%26oauth_signature_method%3DHMAC-SHA1%26oauth_timestamp%3D1276236145594%26oau th_version%3D1.0.
