在Node.js中,可以使用mime-types库来判断文件的MIME类型,从而实现只允许上传PDF文件的功能。以下是实现的步骤: 1. 首先,确保已经安装了mime-types库。可以使用以下命令...
如前所述,mime是设定文件类型的,css,html文件的类型归类是"text/",但是视频文件3gp等是"video/",图片文件jpeg是"image/",··· 互联网上还有很多很多的格式,而我们又必须它们一个一个都实现,这才有了统一又方便可重用的mime模块 文末也会贴出近乎所有mime类型 2、使用mime模块设定文件类型 //cnpm install m...

很多图片音频等文件,有时候可能需要读取到数据中或者放到单文件的HTML中时,将它们转换成为base64格式是一个好方法,nodejs可以很方便的把文件转换为base64格式: 需要依赖库“fs”,“path”,“mime-types”,库mime-types可通过npm安装,具体的代码如下:
├── type-is@1.6.1 (media-typer@0.3.0, mime-types@2.0.10) ├── accepts@1.2.5 (negotiator@0.5.1, mime-types@2.0.10) ├── send@0.12.2 (ms@0.7.0, destroy@1.0.3, mime@1.3.4) ├── proxy-addr@1.0.7 (forwarded@0.1.0, ipaddr.js@0.1.9) ...

1) 图片转换成2进制 网上应该有很多的工具 那 我用nodejs 写了一个 var http=require('http'); const fs = require("fs"); const mineType = require("mime-types"); var db = http.createServer(function(request,response) { var path= imgToBase64(__dirname+'\\logo.png') ...
MIME类型支持 像其他服务器一样,支持MIME的话,就得一张映射表。 exports.types = { "css": "text/css", "gif": "image/gif", "html": "text/html", "ico": "image/x-icon", "jpeg": "image/jpeg", "jpg": "image/jpeg", "js": "text/javascript", ...
varcontentType=MIMETYPES[path.extname(pathname)];res.writeHead(200,{"Content-Type":contentType});console.log("Current URI: "+uri+" has content type: "+contentType);fs.createReadStream(pathname).pipe(res);return;});}//POST requests wrapperif(req.method=="POST"){varpostData="";req.on(...
