通常在咱们写项目的时候会遇到上传下载什么的，在上传完文件后会把文件的路径保存到数据库里以便下载，如果想不通过后台直接下载的话，可以把文件路径给a标签的属性href； 点击下载 这样当用户打开浏览器点击链接的时候就会直接下载文件。 url_lst = getUrl (html) os.mkdir ('ldf_download') os.chdir (os.path.join (os.getcwd (), 'ldf_download')) for url in url_lst [:]: url = root_url + url. getFile (url) 上面这个例子是个很好的模板。. 当然，上面的还不适用于我的情况，我的做法是：先把地址写到了html文件中，然后对正则匹配部分做了些修改，我需要匹配的地址都是这样的，http://pm.zjsti.gov.cn/tempublicfiles/G176200001/G176200001.pdf。. 改进后的代码如下：. 下载也挺简单的，代码如下：. pdfDownload(url){ const id = sessionStorage.getItem('idPdf').replace(/"/g, ''); this.$http({ url: `account/registerOpen/$ {url}`, method: 'get', responseType: 'arraybuffer', params: { accountId: id, lang: 'en_US' } }).then(res => { if (url === 'PerPdf/download' || url === 'PerCrsPdf/download' || url === 'PerWbenContractPdf/download') # 构造下载PDF函数体 downloadPDF = function(filename,Lurl,folder,handle){ dir.create(folder,showWarnings = FALSE) url = str_c(Lurl,filename) if(!file.exists(str_c(folder,"/",filename))){ content = getBinaryURL(url,curl = handle) writeBin(content,str_c(folder,"/",filename)) Sys.sleep(1) } } #爬取链接 LINKS=remDr$getPageSource()[[1]]%>%read_html()%>%html_nodes('p a')%>%html_attr('href') #识别pdf相关链接并处理 LINKS1 = LINKS[str_detect(LINKS,".+pdf… Although the ffile:////.exe used to work (for example - some versions of early html 4) it appears html 5 disallows this.
