JAVA利用HttpClient進(jìn)行POST請求（HTTPS）

目前，要為另一個項目提供接口，接口是用HTTP URL實現(xiàn)的，最初的想法是另一個項目用jQuery post進(jìn)行請求。

但是，很可能另一個項目是部署在別的機(jī)器上，那么就存在跨域問題，而JQuery的post請求是不允許跨域的。

這時，就只能夠用HttpClient包進(jìn)行請求了，同時由于請求的URL是HTTPS的，為了避免需要證書，所以用一個類繼承DefaultHttpClient類，忽略校驗過程。

1.寫一個SSLClient類，繼承至HttpClient

[java] view plain copy

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(jìn)行Https請求的HttpClient
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.寫一個利用HttpClient發(fā)送post請求的類

[java] view plain copy

3.調(diào)用post請求的測試代碼

[java] view plain copy

import java.util.HashMap;
import java.util.Map;
//對接口進(jìn)行測試
public class TestMain {
private String url = "https://192.168.1.101/";
private String charset = "utf-8";
private HttpClientUtil httpClientUtil = null;
public TestMain(){
httpClientUtil = new HttpClientUtil();
}
public void test(){
String httpOrgCreateTest = url + "httpOrg/create";
Map<String,String> createMap = new HashMap<String,String>();
createMap.put("authuser","*****");
createMap.put("authpass","*****");
createMap.put("orgkey","****");
createMap.put("orgname","****");
String httpOrgCreateTestRtn = httpClientUtil.doPost(httpOrgCreateTest,createMap,charset);
System.out.println("result:"+httpOrgCreateTestRtn);
}
public static void main(String[] args){
TestMain main = new TestMain();
main.test();
}
}
