Twitter API集成-遠程服務器返回錯誤：（401）未經授權

Question

我已經嘗試集成twitter API集成，但是沒有運氣，會出現錯誤

“遠程服務器返回錯誤：（401）未經授權。”

您能盡快幫助我嗎？

我的Twitter應用程序詳細信息如下

Access level    Read-only 
About the application permission model

Consumer key    <Consumer Key>
Consumer secret <Consumer Secret>
Request token URL   https://api.twitter.com/oauth/request_token
Authorize URL   https://api.twitter.com/oauth/authorize
Access token URL    https://api.twitter.com/oauth/access_token
Callback URL    http://www.opalevents.org/register
Sign in with Twitter    Yes

我的以下代碼

首先，您的資源網址錯誤，應該是： https : //stream.twitter.com/1.1/statuses/filter.json

注意，有一個新的版本1.1。 您也可以嘗試轉到OAuth工具標簽並重新生成一個新請求，如下所示：

有時我必須重新生成我的憑據，因為它會將我趕出場
