将curl命令转换为Java / Android

Question

有人可以帮我弄清楚如何将以下curl命令转换为Java语法以用于Android应用程序吗？

curl命令为：

curl -L -c cookie1 URL

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，但是我不确定如何存储初始GET响应的cookie，然后在后续的POST中发送它，然后在最终的POST中发送该响应的cookie。

谢谢

这几乎可以正常工作...当我通过新的意图开始活动时，cookie会立即被擦除。 找到更完整的解决方案后，我将编辑此答案，但是以下内容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：

我创建了一个扩展应用程序的应用程序类，并在其中定义了我的DefaultHttpClient，然后在所有其他活动中，我都使用该客户端进行请求。 这允许cookie在我的应用程序中的所有活动之间共享。
