使用apache httpClient客户端将发布数据发送到https而无需ssl证书验证

java

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。

我要发送的帖子数据是XML字符串，而我正在接收的帖子数据是XML字符串。

任何有关此问题的信息将不胜感激。

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

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，我想到了this函数，该函数发送请求并从响应中检索字符串。我认为应该可以。我所缺少的是我对postData不做任何事情。如何发送带有请求的帖子数据？

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 =============");
                }

                public void checkServerTrusted(X509Certificate[] certs,
                                String authType) {
                        System.out.println("checkServerTrusted =============");
                }
    } }, new SecureRandom());

    CloseableHttpClient httpclient = HttpClients.custom().setSSLSocketFactory(new SSLSocketFactory(sslContext)).build();
    HttpPost httpPost = new HttpPost(request);
    ByteArrayEntity postDataEntity = new ByteArrayEntity(postData.getBytes());
    httpPost.setEntity(postDataEntity);
    CloseableHttpResponse response = httpclient.execute(httpPost);
    try {
        HttpEntity entity = response.getEntity();
        result = EntityUtils.toString(entity);
        EntityUtils.consume(entity);
    } finally {
        response.close();
    }
    return result;

}
