我想从 HttpReponse 中获取这个 Response 并将其打印出来。我该怎么做呢？
I tried response.getEntity().toString()but it just seems to print out the address in memory.
我试过了，response.getEntity().toString()但它似乎只是打印出内存中的地址。

Use ResponseHandler. One line of code. See hereand herefor sample Android projects using it.
使用ResponseHandler. 一行代码。有关使用它的示例 Android 项目，请参见此处和此处。
public void postData() {
// Create a new HttpClient and Post Header
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://www.yoursite.com/user");
try {
// Add your data
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
nameValuePairs.add(new BasicNameValuePair("id", "12345"));
nameValuePairs.add(new BasicNameValuePair("stringdata", "AndDev is Cool!"));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
// Execute HTTP Post Request
ResponseHandler<String> responseHandler=new BasicResponseHandler();
String responseBody = httpclient.execute(httppost, responseHandler);
JSONObject response=new JSONObject(responseBody);
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
} catch (IOException e) {
// TODO Auto-generated catch block
}
}
add combination of this post and complete HttpClient at - http://www.androidsnippets.org/snippets/36/
添加这篇文章的组合并在 - http://www.androidsnippets.org/snippets/36/完成 HttpClient

I would just do it the old way. It's a more bulletproof than ResponseHandler, in case you get different content types in the response.
我只会用旧的方式来做。它比 ResponseHandler 更防弹，以防您在响应中获得不同的内容类型。
ByteArrayOutputStream outstream = new ByteArrayOutputStream();
response.getEntity().writeTo(outstream);
byte [] responseBody = outstream.toByteArray();

This code will return the entire response message in respondas a String, and status code in rsp, as an int.
此代码将在返回整个响应消息响应一个String，和状态码在RSP，作为一个int。
respond = response.getStatusLine().getReasonPhrase();
rsp = response.getStatusLine().getStatusCode();`

I used the following code
我使用了以下代码
BufferedReader r = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
StringBuilder total = new StringBuilder();
String line = null;
while ((line = r.readLine()) != null) {
total.append(line);
}
r.close();
return total.toString();

The simplest approach is probably using org.apache.http.util.EntityUtils:
最简单的方法可能是使用org.apache.http.util.EntityUtils：
String message = EntityUtils.toString(response.getEntity());
It reads the contents of an entity and returns it as a String. The content is converted using the character set from the entity (if any), failing that, "ISO-8859-1" is used.
它读取实体的内容并将其作为字符串返回。使用来自实体（如果有）的字符集转换内容，否则使用“ISO-8859-1”。
If necessary, you can pass a default character set explicitly - e.g.
如有必要，您可以显式传递默认字符集 - 例如
String message = EntityUtils.toString(response.getEntity(). "UTF-8");
It gets the entity content as a String, using the provided default character set if none is found in the entity. If the passed default character set is null, the default "ISO-8859-1" is used.
如果在实体中找不到任何内容，则使用提供的默认字符集获取实体内容作为字符串。如果传递的默认字符集为空，则使用默认的“ISO-8859-1”。
