我在使用＆＃34; https://api.twitter.com/1/statuses/update.json?status=Test＆＃34;
时遇到以下错误遵循的步骤：
现在我想使用＆＃34; https://api.twitter.com/1/statuses/update.json?status=Test＆＃34;从salesforce发送推特到推特，但收到以下错误：
response - System.HttpResponse[Status=Authorization Required, StatusCode=401]
response.getBody() - {"errors":[{"code":32,"message":"Could not authenticate you."}]}
OauthString = OAuth oauth_consumer_key="ILFzs0lcUiHwJsbpuWU4tTdk3",oauth_nonce="RElxMGNiWFJMOGp2V2VRcHB5aU96REhqYnVnbHZXc2o",oauth_signature="2aWbL3JASeSgNRaDQ%2BgLNXpH8dA%3D",oauth_signature_method="HMAC-SHA1",oauth_timestamp="1466659830",oauth_token="743383838253002753-L4gdS3UCxKZVGTtQ0SHxSMlVtJREIBk",oauth_version="1.0"
