java在维护Cookie的同时发送GET/POST请求

我使用的是ApacheHttpClient 4.2.5，我试图发送GET/POST请求，同时将cookies从一个请求传递到另一个请求（就像真正的浏览器一样）

有什么类似于PHP的cURL功能吗？cURL简单明了，但在谷歌上很难找到一段代码，它可以满足我在Java中的需求

我想要的很简单。让我发邮件，收到请求。同时，传递cookies，让我设置自己的标题。Java中是否有类似的功能？

HttpClient

只要使用相同的

DefaultHttpClient

对象

来自

Curl

world的东西：

curl -b -L -i  -X POST   
-d 'id=105'  
-d 'json={"orderBy":0,"categoryRelevant":false'}  \ http://env-findwifi.wifi.com/lClient/

**评论：

-b :: enable cookies (by default its disabled)
-L :: activate redirect
-i :: show output

但如果你真的想玩Java，这里有一些代码片段：

List<Cookie> mCookies = null;

...

public void redirect(String url){

    StringBuilder buff = new StringBuilder();

    DefaultHttpClient httpclient = null;
    //      boolean success = false;

        HttpConnectionParams.setSoTimeout(params, m_timeout);            // socket timeout

        HttpClientParams.setRedirecting(params, false);


        httpclient = new DefaultHttpClient(params);


        Log.d("test_runner", "URL: " + url);

        HttpGet httpget = new HttpGet(url);




        HttpContext context = new BasicHttpContext(); 
        HttpResponse response = httpclient.execute(httpget, context);



        //HttpResponse response = httpclient.execute(httpget);

        mCookies = httpclient.getCookieStore().getCookies();

        if (mCookies.isEmpty()) {
            Log.d("test_runner", "Cookies: None");
        } else {
            for (int i = 0; i < mCookies.size(); i++) {
                System.out.println("- " + mCookies.get(i).toString());
                Log.d("test_runner", "Cookies: [" + i + "]" + mCookies.get(i).toString());

        int statusCode =  response.getStatusLine().getStatusCode();

            Header[] headers = response.getHeaders("Location");

            if (headers != null && headers.length != 0) {
                String newUrl =  headers[headers.length - 1].getValue();

                redirect(newUrl);                   

            } 
        }   
        else{ // status 200

            HttpHost currentHost = (HttpHost)  context.getAttribute(ExecutionContext.HTTP_TARGET_HOST);

            mHost = currentHost.toURI();

            HttpEntity entity = response.getEntity();

            if (entity != null) {


                InputStream is = entity.getContent();
                InputStreamReader isr = new InputStreamReader(is);
                BufferedReader br = new BufferedReader(isr, 1024 * 4);
                String line = null;
                while ( (line = br.readLine()) != null) {
                    //System.out.println("Data Sender: " +  line);

                    buff.append(line).append("\n");

                }
                is.close();

            } else {

        }
    } catch (Exception e) {

在您可以将cookies用于post后：

        String inputRootName, String onSubmitName, String onSubmitVal) {

    HttpConnectionParams.setStaleCheckingEnabled(params, false);
    HttpConnectionParams.setSocketBufferSize(params, 8192);



    HttpClientParams.setRedirecting(params, false);


     CookieStore cookieStore = new BasicCookieStore(); 



     for(Cookie cook : mCookies){
         cookieStore.addCookie(cook); 
     }

     httpclient = new DefaultHttpClient(params);
     httpclient.setCookieStore(cookieStore);

     if(mHost != null){
         formAction =  mHost + "/www/" + formAction; 
     }
     else{
         formAction =  "http://localhost/www/" + formAction; 
     }




    HttpPost httpost = new HttpPost(formAction);

    List <NameValuePair> nvps = new ArrayList <NameValuePair>();
    nvps.add(new BasicNameValuePair(inputRootName, inputRootValue));
    nvps.add(new BasicNameValuePair(onSubmitName, onSubmitVal));


    httpost.setEntity(new UrlEncodedFormEntity(nvps, HTTP.UTF_8));




    HttpResponse response = httpclient.execute(httpost);

    HttpEntity entity = response.getEntity();

    if (entity != null) {

        StatusLine statusLine = response.getStatusLine();
        int statusCode = statusLine.getStatusCode();

        if(statusCode != 200){

        }

        Log.d("test_runner", "response.getStatusLine: " + response.getStatusLine());

        InputStream is = entity.getContent();
        InputStreamReader isr = new InputStreamReader(is);
        BufferedReader br = new BufferedReader(isr);
        String line = null;
