将 curl 命令翻译成 Java/Android

Question

谁能帮我弄清楚如何将以下 curl 命令转换为 Java 语法以在 Android 应用程序中使用？

curl 命令是：

curl -L -c cookie1 网址 curl -L -c cookie2 -b cookie1 -d "loginId=NAME&password=PASSWORD&_eventId_submit=Submit" URL2 curl -L -c cookie3 -b cookie2 -d "_eventId_submit=Submit" URL3

特别是 cookie 的存储和发送。其余的我可以管理，但我不确定如何存储初始 GET 响应的 cookie，然后将其与后续 POST 一起发送，然后将该响应的 cookie 与最终 POST 一起发送。

谢谢

这几乎可以工作...当我通过新意图启动活动时，cookie 会立即被清除。一旦我想出一个更完整的解决方案，我将编辑这个答案，但以下确实会生成所需的身份验证 cookie。

try {

        HttpGet httpget = new HttpGet("url1");
        client.getCookieStore().getCookies();
        HttpResponse response1 = client.execute(httpget);
        HttpEntity entity1 = response1.getEntity();
        if (entity1 != null){
            entity1.consumeContent();
        }
        if (cookies.isEmpty()) {
            System.out.println("None");
        } else {
            for (int i = 0; i < cookies.size(); i++) {
                System.out.println("- " + cookies.get(i).toString());
                cookie = cookies.get(i);
            }
        }


    } catch (ClientProtocolException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    } catch (IOException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    }

    try {
        List<NameValuePair> nvps = new ArrayList<NameValuePair>();
        nvps.add(new BasicNameValuePair("loginId", username.toString()));
        nvps.add(new BasicNameValuePair("password", password.toString()));
        nvps.add(new BasicNameValuePair("_eventId_submit", "Submit"));

        HttpPost httppost = new HttpPost("url2");
        httppost.setEntity(new UrlEncodedFormEntity(nvps, HTTP.UTF_8));
        HttpParams params = httppost.getParams();
        HttpConnectionParams.setConnectionTimeout(params, 45000);
        HttpConnectionParams.setSoTimeout(params, 45000);

        // Perform the HTTP POST request
        HttpResponse response = client.execute(httppost);
        status = response.getStatusLine().toString();
        if (!status.contains("OK")) {
            throw new HttpException(status);
        }

        if (cookies.isEmpty()) {
            System.out.println("None");
        } else {
            for (int i = 0; i < cookies.size(); i++) {
                System.out.println("- " + cookies.get(i).toString());
                cookie = cookies.get(i);
            }
        }


    } catch (UnsupportedEncodingException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (HttpException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (ClientProtocolException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    try {
        List<NameValuePair> nvps2 = new ArrayList<NameValuePair>();

        nvps2.add(new BasicNameValuePair("_eventId_submit", "Submit"));

        HttpPost httppost2 = new HttpPost("url3");
        httppost2.setEntity(new UrlEncodedFormEntity(nvps2, HTTP.UTF_8));
        HttpParams params2 = httppost2.getParams();
        HttpConnectionParams.setConnectionTimeout(params2, 45000);
        HttpConnectionParams.setSoTimeout(params2, 45000);

        // Perform the HTTP POST request
        HttpResponse response2 = client.execute(httppost2);
        if (cookies.isEmpty()) {
            System.out.println("None");
        } else {
            for (int i = 0; i < cookies.size(); i++) {
                System.out.println("- " + cookies.get(i).toString());
                cookie = cookies.get(i);
                settings.setASCookie(cookie);
            }
        }

        } catch (UnsupportedEncodingException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (ClientProtocolException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

编辑：

我创建了一个扩展 Application 的应用程序类，并在那里定义了我的 DefaultHttpClient，然后在我的所有其他活动中，我使用该客户端进行请求。这允许在我的应用程序中的所有活动之间共享 cookie。
