PDF.js报错workerSrc修复

在项目中使用PDF.js展示PDF报错

pdf.js:8715 Uncaught (in promise) Error: No "GlobalWorkerOptions.workerSrc" specified.
at getWorkerSrc (pdf.js:8715)
at PDFWorker_initialize [as _initialize] (pdf.js:8798)
at new PDFWorker (pdf.js:8776)
at Object.getDocument (pdf.js:7991)
at s.loadFile (PDF.vue:88)
at mysubinfos.vue:295

解决方法

1、// 必须要指定workerSrc属性.

pdfjsLib.GlobalWorkerOptions.workerSrc = '//mozilla.github.io/pdf.js/build/pdf.worker.js';

2、 修改 api.js 中的 getWorkerSrc() 函数

//默认实现
function getWorkerSrc() {
if (GlobalWorkerOptions.workerSrc) {
return GlobalWorkerOptions.workerSrc;
}
if (typeof workerSrc !== 'undefined') {
return workerSrc;
}
if (typeof PDFJSDev !== 'undefined' &&
PDFJSDev.test('PRODUCTION && !(MOZCENTRAL || FIREFOX)') &&
pdfjsFilePath) {
return pdfjsFilePath.replace(/(\.(?:min\.)?js)(\?.*)?$/i, '.worker$1$2');
}
throw new Error('No "GlobalWorkerOptions.workerSrc" specified.');
}


//修改后
function getWorkerSrc() {
return pdfjsFilePath.replace('pdf.js', 'pdf.worker.js');}
