基于https，HttpsURLConnection客户端代码调用

2019独角兽企业重金招聘Python工程师标准>>>

今天遇到配置了SSL的服务器，不知道怎么写客户端调用，费了一定时间还是折腾通了，mark下与大家共勉

[java] view plain copy

1. System.setProperty("javax.net.ssl.keyStore","c:\\tomcat.jks");    
2.             System.setProperty("javax.net.ssl.keyStorePassword","12345678");     
3.             System.setProperty("javax.net.ssl.trustStore","c:\\tomcat.jks");     
4.             System.setProperty("javax.net.ssl.trustStorePassword","12345678");     
5.         String urlResouce = "https://localhost:8443/cloud-storeage-boss/cai:images:public/11汉字.jpg"; // create URL  
6.         File localFile = new File("C:\\Users\\Public\\Pictures\\Sample Pictures\\Penguins.jpg");  
7.         try{  
8.               
9.         HttpsURLConnection urlConnection =  
10.         (HttpsURLConnection) (new URL(urlResouce)).openConnection();  
11.         urlConnection.setRequestProperty("Charset", "UTF-8");  
12.         urlConnection.setDoInput(true);  
13.         urlConnection.setDoOutput(true);  
14.         urlConnection.setRequestMethod("PUT");  
15.         OutputStream urlOutputStream = urlConnection.getOutputStream();  
16.         FileInputStream fileInputStream = new FileInputStream(localFile);  
17.         IOUtils.copy(fileInputStream, urlOutputStream);  
18.         fileInputStream.close();  
19.         urlOutputStream.close();  
20.         System.out.println(urlConnection.getResponseCode());  
21.         }  
22.         catch(Exception e)  
23.         {  
24.             e.printStackTrace();  
25.         }  

关键就是系统参数的设置，将证书设置到系统中去，如果已经将安全证书安装到JDK那就很easy了
