android应用程序中的http响应中缺少cookie

Question

我正在尝试使用来自 android 应用程序的 apache HttpClient 向服务器发出请求，但我得到的响应没有标头 Set-Cookies。 我尝试在桌面应用程序上做同样的事情并且它有效，我收到了所有标题。 我究竟做错了什么？帮帮我，请解决这个问题。

HttpClient httpclient1 = new DefaultHttpClient();
        HttpGet req1 = new HttpGet("http://www.example.com");
        req1.addHeader("Accept", "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8");
        req1.addHeader("Accept-Encoding", "gzip,deflate,sdch");
        req1.addHeader("Accept-Language", "ru,en-US;q=0.8,en;q=0.6,uk;q=0.4");
        req1.addHeader("Connection", "keep-alive");
        req1.addHeader("Host", "www.example.com");
        req1.addHeader("User-Agent", "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/34.0.1847.131 Safari/537.36");
        String cookie = "";
        try {
            HttpResponse response1 = httpclient1.execute(req1);
            Header[] headers = response1.getAllHeaders();
            for (int i = 0; i < headers.length; i++) {
                System.out.println(headers[i] + "");
                if (headers[i].toString().startsWith("Set-Cookie: "))
                    cookie = headers[i].toString().substring(12);
            }   

            HttpClient httpclient = new DefaultHttpClient();

            HttpPost postRequest = new HttpPost("http://www.example.com/1.php");
            postRequest.addHeader("Referer", "http://www.example.com/2.php");
            if (cookie.length() > 0) {
                cookie = cookie.replace(" path=/", "");
                postRequest.addHeader("Cookie", cookie);
            }

            List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
            nameValuePairs.add(new BasicNameValuePair("username", "my-username"));
            nameValuePairs.add(new BasicNameValuePair("password", "my-password"));
            postRequest.setEntity(new UrlEncodedFormEntity(nameValuePairs));

            HttpResponse response = httpclient.execute(postRequest);
            Header[] hs = postRequest.getAllHeaders();
            for (int i = 0; i < hs.length; i++) {
                System.out.println(hs[i] + "");
            }
            System.out.println(response.getStatusLine().getStatusCode() + "");
            Header[] hs3 = response.getAllHeaders();
            for (int i = 0; i < hs3.length; i++) {
                System.out.println(hs3[i] + "");
            }
        } catch (ClientProtocolException e) {
            e.printStackTrace();
            System.err.println("ClientProtocolException");
        } catch (IOException e) {
            e.printStackTrace();
            System.err.println("IOException");
        }

这是我使用 android 应用收到的标题：

这是来自桌面应用程序：

Answer 1

您必须能够访问请求中的标头。

比较它们......它们不会是一样的......

请特别注意以下几点：]

MimeType 标头值

帖子正文 - “名称”、“密码”的表单值究竟会发生什么，并且是 android 的帖子正文与 webapp 发送的内容完全相同。

验证 webapp 是 POST 而不是 GET。

HttpPost postRequest = 新的HttpPost

上面的行设置了一组默认的 Post 标头，您的服务器正在处理的标头与 destops 标头集合非常不同。

比较各自的标头，通过在您的 android 应用程序中添加/删除适当的标头来平衡它们，您将从 nginx 获得相同的结果......
