在main.js中添加如下代码，前提是引入cos的sdk。

 //--上传到腾讯cos，这段代码写在main.js中var Bucket = 'test-xxxxxxx';var Region = 'ap-shanghai'; /* 存储桶所在地域，必须字段 */let CosAuth = null;let getCosAuth = (callback) => {    $.ajax({       type: "POST",       contentType: "application/json;charset=UTF-8",      headers: {          'Content-Type': 'application/json;charset=utf8',            'Authorization':  localStorage.getItem("token")     },      url: rootUrl + "/api/admin/get-cos-key",        //后端接口返回临时秘钥信息      data: null,     //请求成功，这段是cos代码     success: function(data) {           var credentials = data.data && data.data.credentials;           if (!data || !credentials) return console.error('credentials invalid');         CosAuth = ({                TmpSecretId: credentials.tmpSecretId,               TmpSecretKey: credentials.tmpSecretKey,             XCosSecurityToken: credentials.sessionToken,                // 建议返回服务器时间作为签名的开始时间，避免用户浏览器本地时间偏差过大导致签名错误             StartTime: data.data.start_time, // 时间戳，单位秒，如：1580000000                ExpiredTime: data.data.expiredTime, // 时间戳，单位秒，如：1580000900         });                     callback()      },      //请求失败，包含具体的错误信息        error: function(e) {            console.log(e.status);          console.log(e.responseText);        }   });}  Vue.prototype.uploadOss = fileObj => {    //重点，getAuthorization内部封装函数    let getCosAuth2 = (options, callback) => {       callback(CosAuth)    }      getCosAuth(() => {      var cos = new COS({         getAuthorization: getCosAuth2//重点调用函数       });     let outurl ="我的域名";             var myDate = new Date();        var ossPath = 'files/' + myDate.getFullYear() + "-" + (myDate.getMonth() + 1);      // 获取文件后缀       var pathArr = fileObj.file.name.split('.')      //  随机生成文件名称        var fileRandName = Date.now() + "" + parseInt(Math.random() * 1000)     var fileName = fileRandName + '.' + pathArr[pathArr.length - 1]     // 要提交的key      var fileKey = ossPath + "/" + fileName;     let formdata = {            Bucket: Bucket,             Region: Region,         Key: fileKey,           Body: fileObj.file,         onTaskReady: function(tid) {                            },          onHashProgress: function(progressData) {                            },          onProgress: function(progressData) {                                if(fileObj.onProgress){                 fileObj.onProgress(progressData)                }                           },      }       cos.putObject(formdata, function(err, data) {           if (!err&&fileObj.onSuccess) {              fileName = fileName.toLocaleLowerCase();                //计算图片高度                if (fileName.indexOf(".jpg") > 0 || fileName.indexOf(".jpeg") > 0 || fileName.indexOf(".png") > 0 || fileName                   .indexOf(                       ".gif") > 0 || fileName.indexOf(".bmp") > 0) {                              var reader = new FileReader();                  reader.readAsDataURL(fileObj.file);                 reader.onload = function(theFile) {                     var image = new Image();                        image.src = theFile.target.result;                      image.onload = function() {                         fileObj.onSuccess({                             src: outurl + "/" + fileKey + "?s=" + this.width + "_" + this.height,                               fileName: fileObj.file.name                         })                                  };                  };              } else {                    fileObj.onSuccess({                     src: outurl + "/" + fileKey,                        fileName: fileObj.file.name                 })              }                       }                               }); })  }

vue文件里的upload组件修改，主要修改:http-request="uploadOss" 和 action=""这两个地方

<el-upload action="" :http-request="uploadOss" :multiple="true" :on-success="uploadCoverMore" :show-file-list="false" name="image">       <el-button  size="small" type="primary">批量上传</el-button>      </el-upload>

在 组件的success回调中会获取到返回的url和图片名称信息，如果需要上传进度，在onProgress方法中回调即可
