我已经迫不及待地想得到这篇文章的内容了

尝试从web浏览器访问此页面时不需要身份验证，但当我尝试从web应用程序获取内容时，会得到sso文件作为响应。我使用的代码如下：

HttpClient httpClient = new DefaultHttpClient();
HttpGet httpGet = new HttpGet("http://search.lib.monash.edu/primo_library/libweb/action/search.do?dscnt=1&frbg=&tab=default_tab&srt=rank&ct=search&mode=Basic&dum=true&tb=&indx=1&vl%28freeText0%29=java&fn=search&vid=MON");
HttpResponse httpResponse = httpClient.execute(httpGet);
HttpEntity responseEntity = httpResponse.getEntity();


BufferedReader in = new BufferedReader(
            new InputStreamReader(responseEntity.getContent()));
    String inputLine;
    StringBuffer response = new StringBuffer();


    while ((inputLine = in.readLine()) != null) {
        response.append(inputLine);
    }
    in.close();

    System.out.println(response.toString());

作为响应，我得到的sso文件如下所示：

HttpClient httpClient = new DefaultHttpClient();
HttpGet httpGet = new HttpGet("http://search.lib.monash.edu/primo_library/libweb/action/search.do?dscnt=1&frbg=&tab=default_tab&srt=rank&ct=search&mode=Basic&dum=true&tb=&indx=1&vl%28freeText0%29=java&fn=search&vid=MON");
HttpResponse httpResponse = httpClient.execute(httpGet);
HttpEntity responseEntity = httpResponse.getEntity();


BufferedReader in = new BufferedReader(
            new InputStreamReader(responseEntity.getContent()));
    String inputLine;
    StringBuffer response = new StringBuffer();


    while ((inputLine = in.readLine()) != null) {
        response.append(inputLine);
    }
    in.close();

    System.out.println(response.toString());

请帮助。

这不是因为任何身份验证问题

返回的页面有一个与

正文相关联的onload
事件。因此，当您在浏览器客户端中打开引用的URL时
它首先接收您在response
绳子
然后它尝试渲染和显示它
但是，同时，onload事件触发并加载URL作为
由location='/goto/..
定义
并且，在显示当前页面之前，会收到新页面
并显示在浏览器上
根据您收到的回复，请注意以下事项：

在JAVA代码中，您只是从指定的URL读取内容。

并且您不会将其传递给任何内容解析器来呈现和显示。除非如此，否则它将被视为静态文本
因此，与web浏览器相比，您在JAVA代码中看不到响应
其他建议：

当您读取一行并将其附加到缓冲区时，最好也将CRLF附加到该行
更改：
    response.append(inputLine);

致：
它使响应文本多行且更具可读性。
感谢您的解释，我真的不明白发生了什么！在我的应用程序中，我只想将搜索结果作为静态文本进行某种处理。如果我转到“go to”URL，那么我会转到正确的页面，但它只涉及java代码，而不涉及呈现的结果。我现在想知道如何获得搜索结果。非常感谢你的帮助！对于搜索结果，您最好依赖该站点提供的任何RSS提要服务（如果可用）。否则，您需要任何第三方工具。系统没有任何类型的API。你推荐什么工具来做这件事吗？谢谢目前我手头没有关于这些工具的任何此类信息。
