pdf.js和pdf.worker.js下载

您可以在以下网址下载pdf.js和pdf.worker.js文件：

pdf.js：https://github.com/mozilla/pdf.js/releases

pdf.worker.js：https://github.com/mozilla/pdf.js/blob/main/build/pdf.worker.js

请注意，pdf.worker.js是pdf.js库的一部分，用于处理PDF文件的工作线程。您需要同时下载并引用这两个文件才能正确使用pdf.js库。

Uni-app的小程序项目中对于现有路径下common/js/pdf.js和common/js/pdf.worker.js的2个文件，如何获取所选pdf文件的总页数

在Uni-app的小程序项目中，处理PDF文件通常需要借助第三方库，比如`pdfjs-dist`，其中包括`pdf.js`核心库和`pdf.worker.js`作为Web Worker用于异步加载。如果你想要获取选定PDF文件的总页数，你需要按照以下步骤操作：

1. 引入依赖：首先，在你的项目里安装pdf.js库，例如通过`uni-app`的npm包管理器，你可以添加以下命令：

   uni-npm install pdfjs-dist

2. 加载并初始化：在需要的地方，导入并初始化pdf.js库，同时加载worker:

   import PDFJS from 'pdfjs-dist';
   PDFJS.getDocumentAsync('/path/to/your/pdf/file.pdf').then(pdf => {
     // 在这里pdf对象表示已加载的PDF文档
   });

3. 获取页数：当文档加载完成后，可以调用`getNumberOfPages()`方法获取总页数：

   pdf.then(pdfObj => {
     return pdfObj.getNumberOfPages();
   }).then(pageCount => {
     console.log('PDF总页数:', pageCount);
   });

4. 错误处理：别忘了处理可能出现的错误，例如网络请求失败、PDF解析错误等。

These dependencies were not found: * canvas in ./node_modules/pdfh5/js/pdf.js * dommatrix/dist/dommatrix.js in ./node_modules/pdfh5/js/pdf.js, ./node_modules/pdfh5/js/pdf.worker.js * web-streams-polyfill/dist/ponyfill.js in ./node_modules/pdfh5/js/pdf.js, ./node_modules/pdfh5/js/pdf.worker.js

It seems that some dependencies required by PDFH5 are missing. To resolve these dependencies, you can follow these steps:

1. Install missing dependencies: Run the following command in your project's root folder to install the missing dependencies:

   npm install canvas dommatrix web-streams-polyfill

This will install the required packages (`canvas`, `dommatrix`, and `web-streams-polyfill`) and add them to your project's `node_modules` folder.

2. Import the dependencies: In the file `pdf.js` located in `node_modules/pdfh5/js/`, add the following import statements at the top of the file:

   import 'canvas';
   import 'dommatrix/dist/dommatrix.js';
   import 'web-streams-polyfill/dist/ponyfill.js';

Similarly, in the file `pdf.worker.js` located in `node_modules/pdfh5/js/`, add the same import statements at the top of the file.

3. Save the changes and rebuild: After adding the import statements, save the files and rebuild your project. Depending on your build system (Webpack, Rollup, etc.), you might need to run a command like `npm run build` or `npm run dev` to rebuild your project with the updated dependencies.

By following these steps, you should be able to resolve the missing dependencies for PDFH5.
