vue中服务端返回的流文件预览成pdf```html ``` ```js axios({ url , method: "


<iframe :src='src' frameborder="0" style="width: 100%; height: 100%"></iframe>

axios({
        url ,
        method: "get`",`
        responseType: 'arraybuffer', // 关键，必须要设置响应类型，否则pdf没有内容都是空白页

        const binaryData = [];
        binaryData.push(res.data);       
        this.src = window.URL.createObjectURL(new Blob(binaryData, {type: 'application/pdf'}));
