java - BufferedReader 由 HTTPClient 终止

Question

这个问题已经有答案了:

After HTTP GET request, the resulting string is cut-off - content has been consumed (4 个回答)

已关闭 10 年前。

所以我有一个服务器和一个客户端。

服务器发送如下

public void doGet(HttpServletRequest req, HttpServletResponse resp) throws IOException        
   StringBuilder builder = new StringBuilder();
   resp.setContentType("text/plain");

      DO A LOT OF THINGS AND WRITE IT INTO ONE JSONARRAY

   builder.append(JsonArray.toString());
   resp.getWriter().println(builder);
}

客户端收到如下:

 private class GetXMLTask extends AsyncTask<String, Void, String> {
    @Override
    protected String doInBackground(String... urls) {
        String output = null;
        for (String url : urls) {
            output = getOutputFromUrl(url);
        }
        return output;
    }

    private String getOutputFromUrl(String url) {
        String output = null;
        try {
            DefaultHttpClient httpClient = new DefaultHttpClient();
            HttpGet httpGet = new HttpGet(url);

            HttpResponse httpResponse = httpClient.execute(httpGet);
            HttpEntity httpEntity = httpResponse.getEntity();

            InputStream in = httpEntity.getContent();
            BufferedReader reader = new BufferedReader(new InputStreamReader(in));

            String line = "";
            StringBuilder builder = new StringBuilder();

            while ((line = reader.readLine()) != null) {
                builder.append(line + "\n");
            }
            Log.i("Test", builder.toString());
            in.close();

            httpClient.getConnectionManager().shutdown();
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        } catch (ClientProtocolException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
        return output;
    }

客户端从异步任务获取数据。

问题是客户端没有收到服务器发送的全部内容。我尝试制作一个 reader.read()，但也存在同样的问题。

如果我尝试通过浏览器获取代码，我会从服务器接收所有数据，但在我的 java 应用程序中却不会。所以服务器是完全正确的，也许我可以更改 jsonarray 并在每个 jsonobject 之后添加一个\n 。

logcat 是否有问题，因为它的字符串有问题，因为字符串太长？

感谢您的帮助。

Answer 1

在方法“getOutputFromUrl”中，没有任何内容分配给“output”
