使用httpclient的Android项目-->http.client (apache), post/get 方法 [英] Android project using httpclient --> http.client (apache), post/get method

问题描述

我正在为一个 android 项目执行 Get 和 Post 方法，我需要将 HttpClient 3.x翻译"到 HttpClient 4.x(由 android 使用).我的问题是我不确定我做了什么，我没有找到某些方法的翻译"......

I'm doing a Get and Post method for an android project and I need to "translate" HttpClient 3.x to HttpClient 4.x (using by android). My problem is that I'm not sure of what I have done and I don't find the "translation" of some methods...

这是我已经完成的 HttpClient 3.x 和 (-->) HttpClient 4.x翻译"，如果我找到了它(只有问我问题的人):

This is the HttpClient 3.x I have done and (-->) the HttpClient 4.x "translation" if I have found it (Only parties who ask me problems) :

HttpState state = new HttpState (); --> ?

HttpMethod method = null; --> HttpUriRequest httpUri = null;

method.abort(); --> httpUri.abort(); //httpUri is a HttpUriRequest

method.releaseConnection(); --> conn.disconnect(); //conn is a HttpURLConnection

state.clearCookies(); --> cookieStore.clear(); //cookieStore is a BasicCookieStore

HttpClient client = new HttpClient(); --> DefaultHttpClient client = new DefaultHttpClient();

client.getHttpConnectionManager().getParams().setConnectionTimeout(SOCKET_TIMEOUT) --> HttpConnectionParams.setConnectionTimeout(param, SOCKET_TIMEOUT);

client.setState(state); --> ?

client.getParams().setCookiePolicy(CookiePolicy.RFC_2109); --> HttpClientParams.setCookiePolicy(param, CookiePolicy.RFC_2109);

PostMethod post = (PostMethod) method; --> ?

post.setRequestHeader(...,...); --> conn.setRequestProperty(...,...);

post.setFollowRedirects(false); --> conn.setFollowRedirects(false);

RequestEntity tmp = null; --> ?

tmp = new StringRequestEntity(...,...,...); --> ?

int statusCode = client.executeMethod(post); --> ?

String ret = method.getResponsBodyAsString(); --> ?

Header locationHeader = method.getResponseHeader(...); --> ?

ret = getPage(...,...); --> ?

不知道对不对.这导致了一些问题，因为包的名称不同，一些方法也是如此.我只需要文档(我还没有找到)和很少的帮助.

I don't know if that is correct. This has caused problems because the packages are not named similarly, and some methods too. I just need documentation (I haven't found) and little help.

推荐答案

回答我的问题最简单的方法是向你展示我制作的课程:

The easiest way to answer my question is to show you the class that I made :

public class HTTPHelp{

    DefaultHttpClient httpClient = new DefaultHttpClient();
    HttpContext localContext = new BasicHttpContext();
    private boolean abort;
    private String ret;

    HttpResponse response = null;
    HttpPost httpPost = null;

    public HTTPHelp(){

    }

    public void clearCookies() {

        httpClient.getCookieStore().clear();

    }

    public void abort() {

        try {
            if(httpClient!=null){
                System.out.println("Abort.");
                httpPost.abort();
                abort = true;
            }
        } catch (Exception e) {
            System.out.println("HTTPHelp : Abort Exception : "+e);
        }
    }

    public String postPage(String url, String data, boolean returnAddr) {

        ret = null;

        httpClient.getParams().setParameter(ClientPNames.COOKIE_POLICY, CookiePolicy.RFC_2109);

        httpPost = new HttpPost(url);
        response = null;

        StringEntity tmp = null;        

        httpPost.setHeader("User-Agent", "Mozilla/5.0 (X11; U; Linux " +
            "i686; en-US; rv:1.8.1.6) Gecko/20061201 Firefox/2.0.0.6 (Ubuntu-feisty)");
        httpPost.setHeader("Accept", "text/html,application/xml," +
            "application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5");
        httpPost.setHeader("Content-Type", "application/x-www-form-urlencoded");

        try {
            tmp = new StringEntity(data,"UTF-8");
        } catch (UnsupportedEncodingException e) {
            System.out.println("HTTPHelp : UnsupportedEncodingException : "+e);
        }

        httpPost.setEntity(tmp);

        try {
            response = httpClient.execute(httpPost,localContext);
        } catch (ClientProtocolException e) {
            System.out.println("HTTPHelp : ClientProtocolException : "+e);
        } catch (IOException e) {
            System.out.println("HTTPHelp : IOException : "+e);
        } 
                ret = response.getStatusLine().toString();

                return ret;
                }
}

我使用本教程来做我的发布方法和那些例子

I used this tutorial to do my post method and thoses examples
