使用httpclient-> http.client（apache）的Android项目

Question

我正在为一个Android项目做一个Get and Post方法，我需要将HttpClient 3.x“翻译”为HttpClient 4.x（由android使用）。我的问题是我不确定自己做了什么，也找不到某些方法的“翻译” ...

这是我已经完成的HttpClient 3.x，如果发现了，则是（->）HttpClient 4.x“翻译”（仅问我问题的各方）：

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(...,...); --> ?

我不知道那是不是正确的。这引起了问题，因为这些软件包的名称和某些方法的名称都不相同。我只需要文档（我还没有找到）和很少的帮助。

回答我的问题的最简单方法是向您展示我的课程：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;                }}
