小编Arp*_*dav的帖子

我是 WebSocket (webRTC) 的新手。我创建了一个视频聊天应用程序。它在本地主机上工作。

服务器

    app.listen(process.env.PORT || 8081, function () {  
   console.log("Example app listening at 8081" )
});
app.get('/', function(req, res){
    res.sendfile('index.html');
});
//require our websocket library 
var WebSocketServer = require('ws').Server; 

//creating a websocket server at port 9090 
var wss = new WebSocketServer({server: app}); 

//all connected to the server users 
var users = {};

客户

//connecting to our signaling server
var HOST = location.origin.replace(/^http/, 'ws');
var conn = new WebSocket(HOST);

conn.onopen = function () { 
   console.log("Connected to the signaling server"); …

我的文档有包含多个对象的数组，我需要找到相关的值并推送到同一个数组中。

我用来@aws-sdk/client-kms加密数据。我得到了 base64 字符串作为响应。现在我得到了Uint8Array。

 const encryptedBlob = await kms.encrypt({
    KeyId: kmsKey,
    Plaintext: Buffer.from(JSON.stringify('data to encrypt')),
  });

加密的明文。当您使用 HTTP API 或 AWS CLI 时，该值是 Base64 编码的。否则，它不是 Base64 编码的。AWS文档中提到

有没有办法在nodeJs中获取base64作为响应。

我在 github 上托管了一个 npm 包。在本地机器上工作时工作正常。但它不会在 docker 构建过程中安装。

Dockerfile

FROM node:14-alpine as base
EXPOSE 8080
ARG LIB_GITHUB_TOKEN
ENV NODE_ENV=production \
LIB_GITHUB_TOKEN="${LIB_GITHUB_TOKEN}"
WORKDIR /home/node/app
RUN chown -R node:node /home/node/app
COPY --chown=node:node package.json package-lock*.json tsconfig.json .npmrc ./
RUN npm install --only=development
RUN ls -a **every pkgs installed except gihub pvt pkg** 
RUN cd node_modules/ && ls
RUN npm run build

.npmrc 文件

registry=https://registry.npmjs.org/
@github_user:registry=https://npm.pkg.github.com/
//npm.pkg.github.com/:_authToken=${LIB_GITHUB_TOKEN}

除了我的 GitHub 私有包之外，所有包都已安装。

与 docker-compose 一样可以正常工作。

如果我添加npm ci --only=production到 dockerfile. 它给 -

npm ERR! code E401 …

Nest无法解析AuthService（？）的依赖项。请验证[0]参数在当前上下文中是否可用。

请找到我的项目资料库

巢式验证测试

Error: Nest can't resolve dependencies of the AuthService (?). Please verify whether [0] argument is available in the current context.
