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
      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;
  }
}
