發送請求到Dropbox的

我面對上執行我的tomacat的servlet這個錯誤....發送請求到Dropbox的

代碼...用於發送數據...

String result= URLEncoder.encode(oauth_token , "UTF-8")+"&";  





     PostMethod get = new PostMethod("https://api.dropbox.com/1/oauth/request_token"); 
     get.addParameter("oauth_consumer_key", "fm5qq8panuw0rnm"); 
     get.addParameter("oauth_nonce",String.valueOf(nonce)); 
     get.addParameter("oauth_signature_method", "PLAINTEXT"); 
     get.addParameter("oauth_signature", result); 
     get.addParameter("oauth_timestamp",String.valueOf(timestamp.getTime()/1000)); 
     get.addParameter("oauth_token", "z3d00yk6qwh2eui"); 


     int status= client.executeMethod(get);

AI正試圖發送POST請求dropbox來獲得request_tok但在執行我的servlet時，我得到這樣的錯誤..通過consle main（）函數執行相同的代碼...我得到正確的結果，但不是從servlet中得到相同的結果

該堆棧軌跡中的哪一行表示您發佈的源代碼中的一行？ –

PostMethod ... – behinddwalls

我沒有看到任何你的代碼在堆棧跟蹤。我希望在某處看到堆棧跟蹤中的「executeMethod」。這個堆棧跟蹤看起來好像與上面提供的代碼無關。 –

您正在請求令牌的PostMethod（「https://api.dropbox.com/1/oauth/request_token」）;

但還傳遞一個令牌作爲參數？

get.addParameter（「oauth_token」，「z3d00yk6qwh2eui」）;
