laravel 实现阿里云oss文件上传功能的示例

这篇文章主要介绍了laravel 实现阿里云oss文件上传功能，本文通过示例代码给大家介绍的非常详细，具有一定的参考借鉴价值,需要的朋友可以参考下

1、定义路由

// 阿里云文件储存Route::group(['prefix'=>'aliyun'], function(){Route::get('sign', 'AliyunController@sign');}); 

2、编写 controller 层

/** * 返回OSS的签名验证 * @return JSON 签名信息 */public function sign(Request $request){//初始化一下必要的请求数据$id = 'xxx'; //AccessKeyId$key = 'xxx';//AccessKeySecret$host = '//xxx.oss-cn-shenzhen.aliyuncs.com';//OSS库地址$cdn_host = "https://img.*x**xx.com"; //真实的访问地址$dir = 'test/';//上传目录设置$callbackUrl = url('upload/callback');//上传回调的地址//上传回调的参数,callbackUrl地址,callbackBody回调接收的参数,callbackBodyType通过POST调用的回调函数,所以要设置这个头$callback_param = array('callbackUrl' => $callbackUrl,'callbackBody' => 'filename=${object}&size=${size}&mimeType =${mimeType}&height=${imageInfo.height}&width=${imageInfo.width}','callbackBodyType' => "application/x-www-form-urlencoded");$callback_string = json_encode($callback_param);//转换成json格式$base64_callback_body = base64_encode($callback_string); //要返回的回调函数参数信息//设置过期时间$now = time();$expire = 60 * 60 * 2; //设置该policy超时时间是 2小时. 即这个policy过了这个有效时间，将不能访问，这里可以根据自己的token过期时间来设置$end = $now + $expire;$expiration = $this->gmt_iso8601($end);//进行时间格式的转换//处理上传限制条件//最大文件大小.用户可以自己设置$condition = array(0 => 'content-length-range', 1 => 0, 2 => 1048576000);$conditions[] = $condition; //设定文件大小//表示用户上传的数据,必须是以$dir开始, 不然上传会失败,这一步不是必须项,只是为了安全起见,防止用户通过policy上传到别人的目录$start = array(0 => 'starts-with', 1 => '$key', 2 => $dir);$conditions[] = $start;//必须以设定的目录开头,防止上传错误$arr = array('expiration' => $expiration, 'conditions' => $conditions);$policy = json_encode($arr);$base64_policy = base64_encode($policy);//要返回的上传限制参数//签名信息$string_to_sign = $base64_policy;$signature = base64_encode(hash_hmac('sha1', $string_to_sign, $key, true));//要返回的签名信息//设置返回信息$response = array('accessid' => $id,//accessid'host' => $host,//上传地址'cdn_host' => $cdn_host,//真实的访问地址'policy' => $base64_policy,//上传文件限制'signature' => $signature, //签名信息'expire' => $end,//失效时间'callback' => $base64_callback_body,//上传回调参数'dir' => $dir //上传的目录);return response()->json(['code' => 0,'msg' => 'success','data' => $response]);}//格式化时间,格式为2020-07-07T23:48:43Zpublic function gmt_iso8601($time){$dtStr = date("c", $time);$pos = strpos($dtStr, '+');$expiration = substr($dtStr, 0, $pos);return $expiration . "Z";}

3、查看接口返回

4、前端界面及操作编写，这里采用的是 vue

<template><div class="test" style="padding:100px 0px 1000px 0px;"><div><input type="file" id="file" name="file" /><a @click="upload()" href="javascript:;" rel="external nofollow" >上传</a></div></div></template><script>export default {data(){return {}},mounted() {this.getOssToken();},methods: {//获取上传通行证getOssToken(){var _self = this; this.axios.get('/aliyun/sign').then((res)=>{var data = res.data;if(data.code==0){ _self.aliyunOssToken = data.data;}else{_self.$message.warning(data.msg);}});},upload(){var _self = this;var getSuffix = function (fileName) {var pos = fileName.lastIndexOf(".");var suffix = '';if (pos != -1) {suffix = fileName.substring(pos);}return suffix;}var file = $("#file").val();if (file.length == 0) {alert("请选择文件");}var oFileName = file.lastIndexOf('\');var oFileName = file.substr(oFileName+1);var fileName = oFileName.lastIndexOf('.');var fileName = oFileName.substr(0,fileName);console.log(fileName);var filename = new Date().getTime() + getSuffix(file);var formData = new FormData();//注意formData里append添加的键的大小写formData.append('key', _self.aliyunOssToken.dir + filename); //存储在oss的文件路径formData.append('OSSAccessKeyId', _self.aliyunOssToken.accessid); //accessKeyIdformData.append('policy', _self.aliyunOssToken.policy); //policyformData.append('Signature', _self.aliyunOssToken.signature); //签名formData.append("file", $("#file")[0].files[0]);formData.append('success_action_status', 200); //成功后返回的操作码var url = _self.aliyunOssToken.host;var fileUrl = _self.aliyunOssToken.cdn_host +'/'+ _self.aliyunOssToken.dir + filename;$.ajax({url: url,type: 'POST',data: formData,// async: false,cache: false,contentType: false,processData: false,success: function (data) {console.log(fileUrl);console.log(data);},error: function (data) {console.log(data);}});}}}</script>

5、点击上传按钮，浏览器控制台输出链接，访问该链接，即可看到该图片
