  • 腾讯云的图片上传与下载

    1、下载cos-js-sdk-v5.js

    下载地址:https://gitee.com/hxnamei/codes/b492wkvnher15p6xyz0q887

    2、引入cos-js-sdk-v5.js文件

    import  COS  from '../../../public/jslib/cos-js-sdk-v5'

    Vue.prototype.COS = COS,

     

     3.配置腾讯云的存储桶

    var COS = Vue.prototype.COS;
    var Bucket = "53-1256586210"; //腾讯云对象储存桶名
    var Region = "ap-shanghai"; //对象储存你所处的地区编号
    var cos = new COS({
      getAuthorization: function(options, callback) {
        var authorization = COS.getAuthorization({
          SecretId: "AKIDujY7RXIWAZqwoSF86pQuJVS9bomUlLQG", // 可传固定密钥或者临时密钥
          SecretKey: "wd5IEuNa7OOSJuFe092hPs63mkTyDBwV", // 可传固定密钥或者临时密钥
          Method: options.Method,
          Pathname: options.Pathname,
          Query: options.Query,
          Headers: options.Headers,
          Expires: 900
        });
        callback({
          Authorization: authorization
          //  XCosSecurityToken: credentials.sessionToken, // 如果使用临时密钥,需要传 XCosSecurityToken
        });
      }
    });
    4、上传和下载的方法
    shangchuan(e) {
          var file = e.target.files[0];
          if (!file) return; // 分片上传文件
          var a = Math.random();
      //上传
          cos.putObject(
            {
              Bucket,
              Region,
              // StorageClass: 'STANDARD',
              Key: file.name,
              Body: file,
              onProgress: function(progressData, callback) {
               
              }
            },
            function(err, data) {
              if(data.statusCode == 200){
                    Vue.prototype.$message({
                        message: '上传成功',
                        type: 'success'
                   })
              }else{
                  Vue.prototype.$message({
                        message: '上传失败',
                        type: 'warning'
                   })
              }
            }
          );
      //得到图片的url
          cos.getObjectUrl(
            {
              Key: file.name,
              Bucket,
              Sign: false,
              Region
            },
            function(err, data) {
              // document.getElementById('imgupload').src=data.Url;
            }
          );
        }
    5、图片展示
    https://20200508-tvweb-1255674295.cos.ap-nanjing.myqcloud.com/+图片名字
    注:https://20200508-tvweb-1255674295.cos.ap-nanjing.myqcloud.com/可以通过  cos.getObjectUrl的document.getElementById('imgupload').src=data.Url;获取
    例子:
     <img :src="`https://20200508-tvweb-1255674295.cos.ap-nanjing.myqcloud.com/${scope.row.background_picture}`">
