老师请问nginx代理http请求,那websocket请求怎么办呢,我试了试也没成功

lxge commented 4 years ago

点击连接会请求这样一个地址: http://192.168.1.169:8091/socket/sample/info?t=1573545217658 不用代理:{"entropy":793761487,"origins":[":"],"cookie_needed":true,"websocket":true} 用了代理会返回404 是不是websocket不方便用代理啊,那是不是在new SockJS时候带上不代理的IP, websocket部分不用代理.是这样吗

gexiangdong commented 4 years ago

如果是websocket，需要在nginx里配置 proxy_http_version 1.1; proxy_set_header Connection "Upgrade"; proxy_set_header Upgrade $http_upgrade; 这几句

例如：

    location /socket/sample {
        proxy_pass http://127.0.0.1:8082;
        proxy_http_version 1.1;
        proxy_set_header Host                       $host;
        proxy_set_header X-Real-IP                  $remote_addr;
        proxy_set_header X-Forwarded-For      $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto    $scheme;
        proxy_redirect                        off;

        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "Upgrade";
    }

        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "Upgrade";
    }

我配了那个了,报错变成了上面那个404,之前报错是连接不了 `map $http_upgrade $connection_upgrade { default upgrade; '' close; }

server
{
    listen 8091;
    #listen [::]:80 default_server ipv6only=on;
    server_name 192.168.1.169;
    index index.html index.htm;
    root  /home/wwwroot/java;

    location / {
        proxy_pass http://192.168.1.169:8090/;
        proxy_set_header Host      $host;
        proxy_set_header X-Real-IP  $remote_addr;
        #CDN发送的头部 设置IP
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_redirect  off;    
    } 

    location /socket {
        #以下配置添加代理头部：
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection $connection_upgrade;
    }

    access_log  /home/wwwlogs/java/access.log;
}

把location /socket那段改成如下试试：

    location /socket {
        proxy_pass http://192.168.1.169:8090;
        proxy_http_version 1.1;
        proxy_set_header Host      $host;
        proxy_set_header X-Real-IP  $remote_addr;

        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_redirect  off;    

        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "Upgrade";
    }

` 把配置换成下面这个以后还是会报错的

gexiangdong commented 4 years ago

你直接连，不经过nginx能连成功吗？我感觉这个错误信息，显示nginx已经转发给后面的 springboot了

gexiangdong commented 4 years ago

还有，你可以加2行日志，然后看看日志里都记录啥了，以便确认访问是转发给springboot了

location /socket {
        # 加上下面这2行
        access_log /home/wwwroot/socket-access.log;
        error_log  /home/wwwroot/socket-error.log;

        proxy_pass http://192.168.1.169:8090;

gexiangdong commented 4 years ago

要我试试，你得把代码发给我啊

怀疑是你的java部分代码问题，哪里返回403了，可能是有全局的filter，spring security等之类的东西拦截了请求就直接返回403 你试试前端js直接连你的8090端口的springboot项目，不经过nginx，这样是否还出错

代码就是老师那个啊 github里面有的,我以为你也弄过这个讲的内容

gexiangdong commented 4 years ago

我的代码我当然得试过，可以运行才能放到github上，也才能讲，这是最最最低的职业道德。你这话说得太……

把section-09下载下来，在section-09目录下运行 mvn spring-boot:run 启动后在浏览器输入 http://localhost:8080/index.html?000 点连接，然后可以发消息这些都没问题

但是我的例子里用到的url端口都和你配置的http://192.168.1.169:8091/socket/sample/info?t=1573545217658 不同, 例子里没有info这段

lxge commented 4 years ago

在升级成websocket协议的之前一步是访问了一下info 也返回了一些json数据.用代理的情况下会报错了,websocket也会报错的.

lxge commented 4 years ago

我的错,我没发现你就是老师啊(^▽^)

gexiangdong commented 4 years ago

我加了nginx，配置这么写的，

    #这段是为了index.html的访问，也可以把这个index.html拷贝到nginx 的www目录下
    location /index.html {
        proxy_pass http://127.0.0.1:8080;
    }  

  # 这段是转发websocket
    location /socket {

        proxy_pass http://127.0.0.1:8080;
        proxy_http_version 1.1;
        proxy_set_header Host      $host;
        proxy_set_header X-Real-IP  $remote_addr;

        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_redirect  off;    

        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "Upgrade";
    }

之后我访问 http://localhost/index.html?000 我的nginx是80端口，成功和，和不用nignx界面一摸一样

gexiangdong commented 4 years ago

我不知道你之前为啥配置 192.168.1.169:8090 nginx和spring-boot不在同一个机器上吗？spring-boot端口你从例子的8080改成了8090吗？现在我直看到这点区别了，刚刚你的截图是localhost:8080的

lxge commented 4 years ago

恩刚刚我为了方便就用了windows下面的,之前那些是打包到linux下运行的,8080我在其他地方有用到,就改成8090和nginx8091了. 老师这边ExceptionHandler重名会报错的,我看半天还以为要添加一个什么插件呢

lxge commented 4 years ago

会不会是linux下面的特殊要求,socket权限啥的,我没有试这个,不过我把jar目录改成777了,还是有报错

gexiangdong commented 4 years ago

肯定不需要jar改成777；但这涉及到你的jar是怎么运行的，是否正常启动了。如果是自己在linux命令行启动，java -jar xxx.jar这种样子，你看到终端上最后的信息，就知道是否正常启动了如果是用systemctl做为daemon运行的，这种情况可能会有权限问题导致启动不起来，权限问题发生在启动的程序需要读写一些文件/目录（例如配置的日志文件）对那些文件没读写权限，给jar设置777没用，需要给对应的目录/文件设置权限要确认启动起来了没有很简单，浏览器访问下http://192.168.1.169:8090/index.html?000就好了

另外那个excepitonhandler重命名报错，你把具体的错误发给我看看。

lxge commented 4 years ago

老师,这个接口返回正常情况下成功失败都会有code,message,data这些属性,失败的情况是抛出异常,用自定义的excepitonhandler接收吗,那成功的时候呢 if(ts == null) { //404 //return ResponseEntity.status(HttpStatus.NOT_FOUND).body(null); throw new ResourceNotFoundException(); } else if (ts.getTvSeriesCharacters().equals(null)) { //403 return ResponseEntity.status(HttpStatus.FORBIDDEN).body(ts); } else { //200 return myExceptionHandler.handleControllerResponse(ts.toString()); //return ResponseEntity.status(HttpStatus.OK).body(ts); } 成功的时候我在那个handler类里这样写的话,返回的结果json的值就都得是字符串了,Map值可以混着来吗,我刚跟着老师学,具体不太清楚. `public class MyExceptionHandler {

@ExceptionHandler(Throwable.class)
@ResponseBody
public ResponseEntity<Object> handleControllerException(
        Throwable ex, WebRequest request){
    Map<String, String> response = new HashMap<>();
    response.put("code", "404");
    response.put("message", "not found");

启动是启动起来了,数据库缓存那部分都没有问题,就是websocket这边会报错,java都打成jar包了,应该怎么给权限啊,我把jar包所在目录给777没有用

lxge commented 4 years ago

老师怎么没有讲一下对接微信这种接口的使用啊,之前我是用php curl实现的,应该java也有.(^▽^)

gexiangdong commented 4 years ago

没别的特殊权限了；只要启动起来了，一般和权限就没关系了。

浏览器访问下http://192.168.1.169:8090/index.html?000 （不过nginx）正常吗？

ExceptionHandler注解的类和执行成功没关系；只有一个访问执行的程序中跑出异常了，而且这个异常自己的程序也没有处理（没有catch），才会进入到对应的ExceptionHandler类里，运行里面的方法，并把结果返回给客户端。

这个是我的PPT上举例不严谨，例子代码片段写的不好，是不该重名的，重名的话，不能import进来，需要使用的时候连package name一起写

如果那个socket还调试不出来，而且你有啥可以远程访问你的环境的方法，可以让我远程找找问题，其他我暂时想不到可能了

lxge commented 4 years ago

老师是用的linux吗,代理websocket,会不会linux下面socket权限之类问题

lxge commented 4 years ago

老师上传文件怎么弄啊,我想试一下传文件到服务器中,这边用fastdfs,可是我不知道这个multipartfile格式的数据除了表单提交有,自己怎么定义一个,试了半天都没成功... ` public Map<String, String> upload(){ // if (log.isTraceEnabled()) { // log.trace("上传文件:"+ filePath); // } File file = new File(filePath); MultipartEntityBuilder builder = MultipartEntityBuilder.create(); builder.addBinaryBody("file", file); HttpEntity entity = builder.build();

    //fastdfsClientUtil.upload(entity);

    Map<String, String> result = new HashMap<>();
    result.put("message", "上传文件:"+filePath);
    return result;
}`

被调用的方法 ` 上传文件 public String upload(MultipartFile myfile) throws Exception{ //文件名 String originalFilename = myfile.getOriginalFilename().substring(myfile.getOriginalFilename().lastIndexOf(".") + 1); // 文件扩展名 String ext = originalFilename.substring(originalFilename.lastIndexOf(".") + 1, originalFilename.length());

  StorePath storePath = this.storageClient.uploadImageAndCrtThumbImage(myfile.getInputStream(), myfile.getSize(),originalFilename , null);

  String path = storePath.getFullPath();

  return path;

websocket连接第一步会请求这个地址,代理的就会报错,看着已经代理给tomcat了,这种错误比较难找.
