JAVA中的HTTPS接口怎么利用HttpClient進行調用？相信很多沒有經驗的人對此束手無策，為此本文總結了問題出現的原因和解決方法，通過這篇文章希望你能解決這個問題。
1.為了避免需要證書，所以用一個類繼承DefaultHttpClient類，忽略校驗過程。
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;
import javax.net.ssl.SSLContext;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;
import org.apache.http.conn.ClientConnectionManager;
import org.apache.http.conn.scheme.Scheme;
import org.apache.http.conn.scheme.SchemeRegistry;
import org.apache.http.conn.ssl.SSLSocketFactory;
import org.apache.http.impl.client.DefaultHttpClient;
/**
* 用于進行Https請求的HttpClient
* @ClassName: SSLClient
* @Description: TODO
* @author Devin <xxx>
* @date 2017年2月7日 下午1:42:07
*
*/
public class SSLClient extends DefaultHttpClient {
public SSLClient() throws Exception{
super();
SSLContext ctx = SSLContext.getInstance("TLS");
X509TrustManager tm = new X509TrustManager() {
@Override
public void checkClientTrusted(X509Certificate[] chain,
String authType) throws CertificateException {
}
@Override
public void checkServerTrusted(X509Certificate[] chain,
String authType) throws CertificateException {
}
@Override
public X509Certificate[] getAcceptedIssuers() {
return null;
}
};
ctx.init(null, new TrustManager[]{tm}, null);
SSLSocketFactory ssf = new SSLSocketFactory(ctx,SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
ClientConnectionManager ccm = this.getConnectionManager();
SchemeRegistry sr = ccm.getSchemeRegistry();
sr.register(new Scheme("https", 443, ssf));
}
}2.創建一個利用HttpClient發送post請求的工具類
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.StatusLine;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.message.BasicHeader;
import org.apache.http.util.EntityUtils;
/**
* 利用HttpClient進行post請求的工具類
* @ClassName: HttpClientUtil
* @Description: TODO
* @author Devin <xxx>
* @date 2017年2月7日 下午1:43:38
*
*/
public class HttpClientUtil {
@SuppressWarnings("resource")
public static String doPost(String url,String jsonstr,String charset){
HttpClient httpClient = null;
HttpPost httpPost = null;
String result = null;
try{
httpClient = new SSLClient();
httpPost = new HttpPost(url);
httpPost.addHeader("Content-Type", "application/json");
StringEntity se = new StringEntity(jsonstr);
se.setContentType("text/json");
se.setContentEncoding(new BasicHeader("Content-Type", "application/json"));
httpPost.setEntity(se);
HttpResponse response = httpClient.execute(httpPost);
if(response != null){
HttpEntity resEntity = response.getEntity();
if(resEntity != null){
result = EntityUtils.toString(resEntity,charset);
}
}
}catch(Exception ex){
ex.printStackTrace();
}
return result;
}
}3.測試代碼
public static void main(String[] args){
String url = "https://192.168.1.101/xxx";
String jsonStr = "{xxx}";
String httpOrgCreateTestRtn = HttpClientUtil.doPost(url, jsonStr, "utf-8");
