WeChat AppletWeChat DevelopmentDetailed explanation on uploading word, txt, Excel, PPT and other files to WeChat mini programDetailed explanation on uploading word, txt, Excel, PPT and other files to WeChat mini program
Currently, the mini program does not have an API that can implement this function, so I implement it here by using web-view;
Implementation process:
1. Configure the business domain name in the background of the mini program
2. Write an html on the server to implement the form upload file
3. The back-end php receives the file and saves it to a server folder, and saves the file name to the database for later retrieval
4. Create a page in the WeChat applet and use web-view to upload files;

Detailed implementation:
1. Configure the business domain name in the mini program background
Address: https://mp.weixin.qq.com/wxopen/appdatacount
2. Write an html on the server to implement the form upload file

<!-- 其实我们可以把iframe标签隐藏掉 -->
<script type="text/javascript">
function upload() {
$("#form1").submit();
var t = setInterval(function() {
//获取iframe标签里body元素里的文字。即服务器响应过来的"上传成功"或"上传失败"
var word = $("iframe[name='frame1']").contents().find("body").text();
if(word != "") {
// alert(word); //弹窗提示是否上传成功

}, 1000);
