Question

我使用commons-httpclient 3.1来读取html页面源代码。除了内容编码为gzip的页面之外，它可以正常工作。我的页面来源不完整。

对于此页面，firefox将内容编码显示为gzip。

以下是详情

我的阅读回复代码：

HttpClient httpclient = new HttpClient();
            httpclient.getParams().setParameter("http.connection.timeout",
                    new Integer(50000000));
            httpclient.getParams().setParameter("http.socket.timeout",
                    new Integer(50000000));


        // Create a method instance.
        GetMethod method = new GetMethod(url);



        // Provide custom retry handler is necessary
        method.getParams().setParameter(HttpMethodParams.RETRY_HANDLER,
                new DefaultHttpMethodRetryHandler(3, false));
        BufferedReader reader = null;
            // Execute the method.
            int statusCode = httpclient.executeMethod(method);

            if (statusCode != HttpStatus.SC_OK) {
                System.err.println("Method failed: "
                        + method.getStatusLine());
                strHtmlContent = null;
            } else {


                InputStream is = method.getResponseBodyAsStream();
                reader = new BufferedReader(new InputStreamReader(is,"ISO8859_8"));
                String line = null;
                StringBuffer sbResponseBody = new StringBuffer();
                while ((line = reader.readLine()) != null) {
                    sbResponseBody.append(line).append("\n");
                }
                strHtmlContent = sbResponseBody.toString();

升级到httpclient 4.1。它应该无缝地支持压缩。

Answer 2

我刚刚在这个问题上招致了这个问题，我解决了以下问题：

    URL url = new URL("http://www.megadevs.com");
    HttpURLConnection conn = (HttpURLConnection) url.openConnection();

    GZIPInputStream gzip = new GZIPInputStream(conn.getInputStream());
    int value = -1;
    String page = "";

    while ((value = gzip.read()) != -1) {
        char c = (char) value;
        page += c;
    }
    gzip.close();

希望这有帮助。
