Java发送https请求代码实例

Java发送https请求代码实例

1、前文：通过webService发送https请求，有两种版本，一种是携带证书验证（比较麻烦），另外一种就是直接忽略证书，本文提供的就是第二种（本人已测试过）

2、最简易代码：

import java.io.IOException;

import java.io.InputStream;

import java.io.InputStreamReader;

import java.io.OutputStream;

import java.io.Reader;

import java.net.MalformedURLException;

import java.net.URL;

import java.text.SimpleDateFormat;

import javax.net.ssl.HostnameVerifier;

import javax.net.ssl.HttpsURLConnection;

import javax.net.ssl.SSLSession;

@SuppressWarnings("all")

public class TestAPI_https {

public static void main(String args[]) throws Exception {

new TestAPI_https().TestRiQingAPI_SaleOrder();

}

public static void TestRiQingAPI_SaleOrder() throws Exception {

String postData = getjson();

//String url = "https://*****";

String url = "https://*****";

HttpsURLConnection conn = null;

OutputStream out = null;

String rsp = null;

byte[] byteArray = postData.getBytes("utf-8");

try {

URL uri = new URL(url);

conn = (HttpsURLConnection) uri.openConnection();

//忽略证书验证--Begin

conn.setHostnameVerifier(new TrustAnyHostnameVerifier());

//忽略证书验证--End

jGAtfNRkg conn.setRequestMethod("POST");

conn.setDoInput(true);

conn.setDoOutput(true);

conn.setRequestProperty("Host", uri.getHost());

conn.setRequestProperty("Content-Type", "application/json");

out = conn.getOutputStream();

out.write(byteArray);

out.close();

if(conn.getResponseCode()==200) {

rsp = getStreamAsString(conn.getInputStream(), "utf-8");

}else {

rsp = getStreamAsString(conn.getErrorStream(), "utf-8");

}

System.out.println(rsp);

} catch (Exception e) {

if(null!=out)

out.close();

e.printStackTrace();

}

}

/**

* getJson

*

*/

private static String getJson() {

return "{" + "\"name\"" + ":" + "\"robo_blogs_zh123\"" + "}";

}

private static String getStreamAsString(InputStream stream, String charset) throws IOException {

try {

Reader reader = new InputStreamReader(stream, charset);

StringBuilder response = new StringBuilder();

final char[] buff = new char[1024];

int read = 0;

while ((read = reader.read(buff)) > 0) {

response.append(buff, 0, read);

}

return response.toString();

} finally {

if (stream != null) {

stream.close();

}

}

}

}

//定制Verifier

class TrustAnyHostnameVerifier implements HostnameVerifier {

public boolean verify(String hostname, SSLSession shttp://ession) {

return true;

}

}
