Java发送https请求代码实例

2020-02-13 12:22 621 查看

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
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 session) {
return true;
}
}

以上就是本文的全部内容,希望对大家的学习有所帮助
