php实现粘贴截图并完成上传功能
今天发现segmentfault的评论留言里面可以粘贴上传图片,于是研究了下怎么实现的!
原理很简单其实就是监控粘贴事件,然后检测是否粘贴的东西里面有图片,有的话直接触发ajax上传
代码可以直接运行,有兴趣你们可以试试

header("Access-Control-Allow-Origin:*"); $url = 'http://'.$_SERVER['HTTP_HOST']; $file = (isset($_POST["file"])) ? $_POST["file"] : ''; if($file) { $data = base64_decode(str_replace('data:image/png;base64,', '', $file)); //截图得到的只能是png格式图片,所以只要处理png就行了 $name = md5(time()) . '.png'; // 这里把文件名做了md5处理 file_put_contents($name, $data); echo"$url/$name"; die; } ?>
<script></script> //查找box元素,检测当粘贴时候, document.querySelector('#box').addEventListener('paste', function(e) {
//判断是否是粘贴图片 if (e.clipboardData && e.clipboardData.items[0].type.indexOf('image') > -1) { var that = this, reader = new FileReader(); file = e.clipboardData.items[0].getAsFile();
//ajax上传图片 reader.onload = function(e) { var xhr = new XMLHttpRequest(), fd = new FormData();
xhr.open('POST', '', true); xhr.onload = function () { var img = new Image(); img.src = xhr.responseText;
// that.innerHTML = ' document.getElementById("img_puth").value = img.src; }
// this.result得到图片的base64 (可以用作即时显示) fd.append('file', this.result); that.innerHTML = ' xhr.send(fd); } reader.readAsDataURL(file); } }, false); |
