在本地运行web-Socket进行调试 [英] Run web-Socket locally for debug

问题描述

我使用大猩猩网络套接字，我想在本地运行它，我的意思是使用下面的chrome客户端
或其他推荐的工具...当我进入调试模式时，我得到了错误

我使用

 github.com/gorilla/websocket
 
 
 var upgrade = websocket.Upgrader {
 ReadBufferSize：1024，
 WriteBufferSize：1024，
} 
 
 upgrader.CheckOrigin = func（r * http .Request）bool {return true} 
 $ bc，err：= upgrader.Upgrade（w，r，nil）
 if err！= nil {
 log.Print（upgrade ：，err）
 return 
} 
  

当我运行以下url在Chrome或Web套接字客户端中，我收到了错误

websocket：不是websocket握手：在'Connection'标题中找不到'upgrade'标记

  localhost：8081 / mypath 
  

我想运行它
$ b $ pre $ $ $ $ c $ ws：// localhost：8081 / mypath

并为本地模拟提供标记，我该怎么做呢？

要检查它，我使用简单的WebSocket客户端。任何其他客户都会有所帮助

编辑：

chrome控制台我得到了以下错误：

VM42：164拒绝连接到'ws：// localhost：8081 / mypath'，因为它
违反了以下内容安全策略指令：connect-src
'self'uploads.github.com status.github.com collector.githubapp.com
api.github.com www。 google-analytics.com github-cloud.s3.amazonaws.com
github-production-repository-file-5c1aeb.s3.amazonaws.com
github-production-upload-manifest-file-7fdce7.s3 .amazonaws.com
github-production-user-asset-6210df.s3.amazonaws.com
wss：//live.github.com

解决方案

浏览器在获取Web页面时不使用WebSocket协议来显示，从浏览器使用WebSocket端点需要代码。

Gorilla包包含示例，显示如何从浏览器进行连接（ chat and
websocket / blob / b89020ee79b89a7f932c5617d218fc06db382f53 / examples / command / home.html＃L31-L45rel =nofollow noreferrer>命令示例是很好的开始）

您可以使用浏览器控制台连接到WebSocket端点：

 > ws = new WebSocket（ws：// localhost：8080 / mypath）
> ws.onmessage = function（ev）{console.log（ev.data）} 
> ws.send（hello）
  

I’m using gorilla web socket and I want to run it locally , I mean with the following chrome client or other recommended tool …when I run into debug mode I got error

I use

"github.com/gorilla/websocket"


var upgrader = websocket.Upgrader{
    ReadBufferSize:  1024,
    WriteBufferSize: 1024,
}

upgrader.CheckOrigin = func(r *http.Request) bool { return true }

c, err := upgrader.Upgrade(w, r, nil)
if err != nil {
    log.Print("upgrade:", err)
    return
}

When I run the following url in chrome or web socket client I got error

websocket: not a websocket handshake: 'upgrade' token not found in 'Connection' header

localhost:8081/mypath

and I want to run it

ws://localhost:8081/mypath

and provide token for local simulation, how I can do it ?

To check it I use Simple WebSocket Client of chrome. any other client will be helpful

EDIT:

when I try it in the chrome console I got the following error:

VM42:164 Refused to connect to 'ws://localhost:8081/mypath' because it violates the following Content Security Policy directive: "connect-src 'self' uploads.github.com status.github.com collector.githubapp.com api.github.com www.google-analytics.com github-cloud.s3.amazonaws.com github-production-repository-file-5c1aeb.s3.amazonaws.com github-production-upload-manifest-file-7fdce7.s3.amazonaws.com github-production-user-asset-6210df.s3.amazonaws.com wss://live.github.com

解决方案

Browsers do not use the WebSocket protocol when fetching a web page for display. Code is required to use a WebSocket endpoint from a browser.

The Gorilla package includes examples showing how to connect from a browser (the chat and command examples are good places to start).

You can can connect to a WebSocket endpoint using the browser console:

> ws = new WebSocket("ws://localhost:8080/mypath")
> ws.onmessage = function(ev) { console.log(ev.data) }
> ws.send("hello")
