前jQuery端接收数据
function upAvatar(img){ console.log(img); // data:image/jpeg;base64,/9j/4AAQSkZJRgABAQAAAQABAAD/2wBDAAMCAgICAgMCAgIDAwMD…/7vA+eq/xZAlzs/wBYlP8AtlpRRXcc9h++B/8AVyJRs30UVRkM2e9M8s+tFFSBE6UUUUGp/9k= $.ajax({ url:‘/user/upload‘, type:‘PUT‘, data:{ imgData: img }, success: function (){
botbox.alert(‘上传成功!‘);
}, error: function (){ bootbox.alert(‘上传失败,请稍后再试!‘); } });}
Nodejs(express)后端接收数据
app.put(‘/user/upload‘,function(req,res){ if(req.body.imgData){ var avatar = req.body.imgData.replace(/^data:image\/\w+;base64,/, ‘‘); var fs = require(‘fs‘), newBuff = new Buffer(avatar, ‘base64‘); fs.writeFile(‘./public/img/‘ + req.session.token + ‘.jpg‘, newBuff, ‘binary‘, function (err) { if (err){ return res.sendStatus(500); } res.sendStatus(200); }); }else{ res.sendStatus(400); }});
nodejs 剪切图像在上传,并保存到指定路径下(./public/img/' + req.session.token + '.jpg‘)
