HTTP请求状态400

Question

我想向Android上的Web服务发送请求，并返回状态400我知道状态400意味着不好的请求，但我不能看到任何错误。我怎样才能解决这个问题？

这是我的请求的代码：

HttpClient httpclient = new DefaultHttpClient(); 
HttpPost httppost = new HttpPost("http://10.0.2.2:1455/Android/Android.svc/GetCompanyBusinessAreas2"); 

try { 
    List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(); 
    nameValuePairs.add(new BasicNameValuePair("company", companhiaIdS)); 

    httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs)); 
    //httppost.g 
    //httppost.setEntity(new StringEntity(companhiaIdS)); 
    Log.i("Enviando:", nameValuePairs.toString()); 

    // Execute HTTP Post Request 
    HttpResponse response = httpclient.execute(httppost); 
    Log.i("Resposta:", response.getEntity().toString()); 
    Log.i("status","" + response.getStatusLine().getStatusCode()); 
    HttpEntity responseEntity = response.getEntity(); 

    char[] buffer = new char[(int) responseEntity.getContentLength()]; 
    Log.i("buffer:","" + responseEntity.getContentLength()); 

    try { 
     InputStream stream = responseEntity.getContent(); 
     InputStreamReader reader = new InputStreamReader(stream); 
     reader.read(buffer); 
     stream.close(); 
     reader.close(); 
    } catch (IOException e) { 
     e.printStackTrace(); 
     Log.i("EXCEPTION", e.getMessage()); 
    } 

    //FIM DA LIGACAO WCF 
    String reply2 = new String(buffer); 
    Log.i("teste", reply2); 


} catch (UnsupportedEncodingException e) { 
    // TODO Auto-generated catch block 
    e.printStackTrace(); 
} catch (ClientProtocolException e) { 
    // TODO Auto-generated catch block 
    e.printStackTrace(); 
} catch (IOException e) { 
    // TODO Auto-generated catch block 
    e.printStackTrace(); 
} 

可变companhiaIdS是一个字符串。

是的，这确实意味着不好的要求。这可能意味着后端无法处理请求
