尝试使用Web Worker时在Karma上显示404 [英] 404 on Karma when trying to use web worker

问题描述

尝试在Web Worker上运行单元测试时出现错误WARN [web-server]: 404: /app/workers/total.js.

I'm getting the error WARN [web-server]: 404: /app/workers/total.js when trying to run a unit test on a web worker.

Karma.conf.js包括以下内容:

...
files: [
        ...
        'app/workers/*.js',
        'unit-tests/mocks/**/*.js',
        'unit-tests/src/**/*.js'
    ],
....

测试如下:

describe('totals', function () {
    var worker;

    beforeEach(function() {
        worker = new Worker('/app/workers/total.js');
    });

    it('should do something', function () {
        ...
    });
});

我尝试了很多网址，但是似乎没有一个

I have tried many urls, but none seem to work

推荐答案

最后，我在

Finally I found the solution on https://github.com/karma-runner/karma/issues/1302, the trick is to include /base as part of the worker URL, being the solution:

describe('totals', function () {
    var worker;

    beforeEach(function() {
        worker = new Worker('/base/app/workers/total.js');
    });

    it('should do something', function () {
        ...
    });
});

注意/base 作为工作人员URL的一部分.

Note /base as part of the worker URL.
