pdf.js实现数据流展示

1:设置ajax返回类型为blob

// pdf预览
export const wordToPdf=  params => {
    return instance.post(`${baseRoot}/app-tool/uploads/word-to-pdf?fileId=${params}`,{},{responseType:'blob'}
    );  
};

2:创建blob地址

          wordToPdf(fileId){
                 toolApi.uploads.wordToPdf(fileId)
                 .then((res)=>{
                     this.src = window.URL.createObjectURL(res);
                 })
            }

3:使用pdf.js展示
