我需要使用 apache HttpClient 包将发布数据发送到 https url，

发送帖子数据后，我需要检索 html 数据。

我发送的帖子数据是一个 XML 字符串，我收到的帖子数据是一个 XML 字符串。

任何有关该问题的信息将不胜感激。

我用谷歌搜索，我在互联网上找到了使用 DefaultHttpClient 的示例，现在版本 4 中已弃用。所以我想知道如何正确使用新版本的客户端。

谢谢。

更新

public String sendPost(final String request, final String postData) throws ClientProtocolException, IOException  {
    String result = null;
    CloseableHttpClient httpclient = HttpClients.createDefault();
    HttpPost httpPost = new HttpPost(request);
    CloseableHttpResponse response = httpclient.execute(httpPost);
    try {
        HttpEntity entity = response.getEntity();
        result = EntityUtils.toString(entity);
        EntityUtils.consume(entity);
    } finally {
        response.close();
    }
    return result;

}

到目前为止，我想出了这个发送请求并从响应中检索字符串的函数。我认为它应该工作。我缺少的是我对 postData 没有做任何事情。如何通过我的请求发送帖子数据？

public String sendPost(final String request, final String postData) throws ClientProtocolException, IOException, NoSuchAlgorithmException, KeyManagementException  {
    String result = null;
    SSLContext sslContext = SSLContext.getInstance("SSL");

    // set up a TrustManager that trusts everything
    sslContext.init(null, new TrustManager[] { new X509TrustManager() {
                public X509Certificate[] getAcceptedIssuers() {
                        System.out.println("getAcceptedIssuers =============");
                        return null;
                }

                public void checkClientTrusted(X509Certificate[] certs,
                                String authType) {
                        System.out.println("checkClientTrusted =============");

这是使用 Apache 4.5 的另一种方法：

/////////////////
// Create SSL Client
/////////////////

CloseableHttpClient httpclient = null;
HttpHost target = new HttpHost('www.mysite.com', 443, "https");

SSLContext sslcontext = SSLContexts.createSystemDefault();
SSLConnectionSocketFactory sslConnectionSocketFactory = new SSLConnectionSocketFactory(
        sslcontext, new String[] { "TLSv1", "SSLv3" }, null,
        SSLConnectionSocketFactory.getDefaultHostnameVerifier());

Registry<ConnectionSocketFactory> socketFactoryRegistry = RegistryBuilder.<ConnectionSocketFactory>create()
        .register("http", PlainConnectionSocketFactory.INSTANCE)
        .register("https", sslConnectionSocketFactory)
        .build();
PoolingHttpClientConnectionManager cm = new PoolingHttpClientConnectionManager(socketFactoryRegistry);

httpclient = HttpClients.custom()
.setSSLSocketFactory(sslConnectionSocketFactory)
.setConnectionManager(cm)
.build();

/////////////////
// Send POST
/////////////////

HttpPost httppost = new HttpPost('/mypath');
ByteArrayEntity postDataEntity = new ByteArrayEntity(postData.getBytes());
httpPost.setEntity(postDataEntity);
CloseableHttpResponse response = httpclient.execute(target, httpPost);

/////////////////
// Get RESPONSE
/////////////////

try {
        HttpEntity entity = response.getEntity();
        result = EntityUtils.toString(entity);
        EntityUtils.consume(entity);
} finally {
        response.close();
}
