java - 在没有使用 apache httpClient 客户端进行 ssl 证书验证的情况下将发布数据发送到 https

Question

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。

我发送的发布数据是一个 XML 字符串，我接收的发布数据是一个 XML 字符串。

如能提供有关此问题的任何信息，我们将不胜感激。

我用谷歌搜索并在互联网上找到了使用 DefaultHttpClient 的示例，现在在版本 4 中已弃用。所以想知道如何正确使用新版客户端。

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，我想出了发送请求并从响应中检索字符串的 this 函数。我认为它应该工作。我缺少的是我没有对 postData 做任何事情。如何随请求发送帖子数据？

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

                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;

}
