当我使用以下代码时,我可以获得数据:
private static String getHttpPostContent(String address, String token) {
try {
HttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost(address);
List<NameValuePair> pairs = new ArrayList<NameValuePair>();
pairs.add(new BasicNameValuePair("token", token));
post.setEntity(new UrlEncodedFormEntity(pairs));
HttpResponse httpResponse = client.execute(post);
HttpEntity entity = httpResponse.getEntity();
String serverResponse = EntityUtils.toString(entity);
return serverResponse;
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
根据我的文档,如果发生错误,则服务器发送错误 418 告诉我发生了错误。我不知道如何抓住它?
当我使用 HTTP GET 方法时,有一种方法可以检查响应代码,如下所示:
int responseCode = conn.getResponseCode();
if (responseCode == HttpURLConnection.HTTP_OK)
...
HTTP POST 方法中是否有类似的方法?
