HTTP正在执行。我的意思是，响应来自服务器，但我无法获取JSON数据。我尝试使用
System.out.print Log.e("response","response get"+response.toString());
HttpResponse response = client.execute(httpGet);
StatusLine statusLine = response.getStatusLine();
int statusCode = statusLine.getStatusCode();
if (statusCode == 200) {
HttpEntity entity = response.getEntity();
InputStream content = entity.getContent();
BufferedReader reader = new BufferedReader(new InputStreamReader(content));
String line;
while ((line = reader.readLine()) != null) {
builder.append(line);
}
} else {
Log.e(ParseJSON.class.toString(), "Failed to download file");
}
我相信响应代码可能不同，这就是为什么你看不到json响应的原因响应代码通常是3位代码，我不确定你为什么会得到5位代码。你可以下载一个名为fiddler的工具，分析从android emulator到服务器的所有流量。即使是这个工具也能帮助你找到确切的问题。还有其他解决方案吗？我会努力找出确切的问题。你有关于这个问题的例子吗？下面是你问题的答案（我在问题中写道）org.apache.http.message。BasicHttpResponse@405722d0Are你确定回复代码是什么？您是否在catch块中放置了一些日志，以确保没有异常，以确保我们没有错过。
