Question

当我使用Postman访问URL时，它工作正常，但通过Android我收到401错误：

04-07 03:53:26.920 850-1142/system_process I/ActivityManager: START u0 {cmp=vems.visioneering.com.vems/.utils.ProfileActivity} from uid 10061 on display 0

04-07 03:53:26.963 26244-26244/vems.visioneering.com.vems D/AndroidRuntime: Shutting down VM

我的代码是：

try {
    DefaultHttpClient client = new DefaultHttpClient();
    client.getParams().setParameter(ClientPNames.ALLOW_CIRCULAR_REDIRECTS, true);
    HttpPost httpPost = new HttpPost(params[1]);
    httpPost.setHeader("Accept", "application/json");
    httpPost.setHeader("Content-type", "application/json");

    StringEntity entity = new StringEntity(params[0]);
    httpPost.setEntity(entity);

    HttpResponse httpResponse = client.execute(httpPost);
    Log.v("httpResponse ",httpResponse.toString());

    int statusCode = httpResponse.getStatusLine().getStatusCode();
    Log.v("Status code", String.valueOf(statusCode));
    if (statusCode == HttpURLConnection.HTTP_OK ||
        statusCode == HttpURLConnection.HTTP_CREATED) {

        HttpEntity httpEntity = httpResponse.getEntity();
        response=EntityUtils.toString(httpEntity);
        Log.v("RESPONSE SERVER COMM : ",response);
        return response;
    }
} catch (Exception e){
// ...
}

我该如何解决这个问题？
