nginx中配置wss的websocket报错：PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

背景

笔者最近在项目中使用websocket,通过nginx进行代理，配置如下

 server {
        listen       443 ssl;
        server_name  www.example.com;

        ssl on;
        ssl_certificate      www.example.com+5.pem;
        ssl_certificate_key  www.example.com+5-key.pem;

        ssl_session_cache    shared:SSL:1m;
        ssl_session_timeout  5m;

        ssl_ciphers  HIGH:!aNULL:!MD5;
        ssl_prefer_server_ciphers  on;

        #charset koi8-r;
        access_log logs/aiPlatform/access_log;
        error_log  logs/aiPlatform/error_log   error;
        
    
        
        location /wsapi/asr {
            proxy_pass http://127.0.0.1:81/api/asr;
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade; 
            proxy_set_header Connection "Upgrade"; 
        }
        
        location /wsapi/asrv2 {
            proxy_pass http://127.0.0.1:81/api/asrv2;
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection "Upgrade"; 
        }
        
        location /wsapi/tts {
            proxy_pass http://127.0.0.1:81/wsapi/tts;
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection "Upgrade"; 
        }            
    }

本地Host文件配置如下

172.112.35.5      www.example.com

 

一开始在java中通过SDK方式调用，可以运行的。

关键代码

 public static void main(String[] args) throws URISyntaxException, InterruptedException, IOException {


    String WS_URL = "ws://127.0.0.1:81/api/asrv2";
    WS_URL="wss://www.example.com/wsapi/asrv2";
    URI uri = new URI(WS_URL);

    CountDownLatch connectClose = new CountDownLatch(1);
    TestASRByChunkClient client = new TestASRByChunkClient(uri, connectClose);

    client.sendByStep();
    client.sendEOS();
    connectClose.await();
}

笔者本地调试，使用自签名证书：https本地自签名证书添加到信任证书访问

后来忽然不能运行了。也不知道为什么。后来查找到原因如下：

将cer证书转换成jks证书，并在ssl通信代码之前指定证书密码

转换命令：

jdk1.8.0_181\jre\bin>keytool -importcert -file "D:\develop\nginx-1.14.2\conf\www.example.com+5.pem" -keystore "D:\develop\nginx-1.14.2\conf\www.example.com+5.jks" -alias "example"

输入密码changeit

 

 然后在使用ssl通信代码之前加以下代码

public static void main(String[] args) throws URISyntaxException, InterruptedException, IOException {

    System.setProperty("javax.net.ssl.trustStore","D:\\develop\\nginx-1.14.2\\conf\\www.example.com+5.jks");
    System.setProperty("javax.net.ssl.trustStorePassword", "changeit");

    String WS_URL = "ws://127.0.0.1:81/api/asrv2";
    WS_URL="wss://www.example.com/wsapi/asrv2";
    URI uri = new URI(WS_URL);

    CountDownLatch connectClose = new CountDownLatch(1);
    TestASRByChunkClient client = new TestASRByChunkClient(uri, connectClose);

    client.sendByStep();
    client.sendEOS();
    connectClose.await();
}

随后代码正常工作
