【Vue】后端返回文件流，前端预览文件

 

let date;        request({          url: this.$route.query.url,          method: 'get',          responseType: 'blob',        }).then(resp => {          date = resp          this.path = window.URL.createObjectURL(new Blob([resp], {type: "application/pdf"}))        }).catch((e) => {          //旧版本浏览器下的blob创建对象          window.BlobBuilder = window.BlobBuilder ||            window.WebKitBlobBuilder ||            window.MozBlobBuilder ||            window.MSBlobBuilder;          if (e.name == 'TypeError' && window.BlobBuilder) {            if (date) {              BlobBuilder.append(date);              this.path = URL.createObjectURL(new BlobBuilder().getBlob("application/pdf"))            }          } else {            console.log("浏览器版本较低，暂不支持该文件类型预览");          }        }).finally(() => {          window.URL.revokeObjectURL(this.path);        })

responseType必须设置为blob
