Reading HttpPost response
提问by Espen
I'm using this code to post a request to a http server:
我正在使用此代码向 http 服务器发布请求：
HttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost( "http://192.168.0.1/test.php" );
HttpResponse response = null;
try {
List< NameValuePair > nameValuePairs = new ArrayList< NameValuePair >( 1 );
nameValuePairs.add( new BasicNameValuePair( "num", "2" ) );
post.setEntity( new UrlEncodedFormEntity( nameValuePairs ) );
response = client.execute( post );
}
catch( ClientProtocolException e ) {
...
}
catch( IOException e ) {
...
}
The response is nothing more than a simple String. How can I read this response as a String? It doesn't seem like HttpResponse have a method for doing this directly.
回应无非是一个简单的String. 我怎么能把这个回复读成一个String？HttpResponse 似乎没有直接执行此操作的方法。

I have created this helper method for sending data and special headers by POST method in Android (headers HashMap could be empty if you do not have any custom headers):
我创建了这个辅助方法，用于在 Android 中通过 POST 方法发送数据和特殊标头（如果您没有任何自定义标头，标头 HashMap 可能为空）：
public static String getStringContent(String uri, String postData,
HashMap<String, String> headers) throws Exception {
HttpClient client = new DefaultHttpClient();
HttpPost request = new HttpPost();
request.setURI(new URI(uri));
request.setEntity(new StringEntity(postData));
for(Entry<String, String> s : headers.entrySet())
{
request.setHeader(s.getKey(), s.getValue());
}
HttpResponse response = client.execute(request);
InputStream ips = response.getEntity().getContent();
BufferedReader buf = new BufferedReader(new InputStreamReader(ips,"UTF-8"));
if(response.getStatusLine().getStatusCode()!=HttpStatus.SC_OK)
{
throw new Exception(response.getStatusLine().getReasonPhrase());
}
StringBuilder sb = new StringBuilder();
String s;
while(true )
{
s = buf.readLine();
if(s==null || s.length()==0)
break;
sb.append(s);
}
buf.close();
ips.close();
return sb.toString();
}

response.getStatusLine();// For reading status line
response.getStatusLine();// 用于读取状态行
org.apache.http.util.EntityUtils.toString(response.getEntity());
