[英]Why am I getting a 404 accessing this file via karma test
MCVE is at this github repo . MCVE 在这个 github repo 。
I'm working on a javascript application that reads a manifest file when loaded.我正在开发一个在加载时读取清单文件的 javascript 应用程序。 I'd like to be able to test that the function works.
我希望能够测试该功能是否有效。 I've got this test function:
我有这个测试功能:
it('We can get a manifest file', function(doneFn) {
manifest=""
console.log(window.location.pathname);
console.log("1")
load_manifest("/Users/joepublic/MCVE/manifest.json");
console.log("2")
console.log(manifest.length)
setTimeout(expect(manifest.length).not.toBeLessThan(1),4000);
console.log(manifest);
doneFn();
});
});
and the function I'm testing looks like this:我正在测试的功能如下所示:
function load_manifest(filename){
//go and get a manifest. We're starting with the one in the root of the template for now.
var req = new XMLHttpRequest();
console.log("a");
req.open("GET", filename);
req.send(null);
req.onload = function() {
if (req.readyState == 4 && req.status == 200) {
console.log("hello");
console.log(req.responseText);
manifest= JSON.parse(req.responseText);
} else {
console.log("Problem reading file");
}
};
console.log("b");
}
The output from karma is:业力的输出是:

I'm getting a 404 - but "ls /Users/joepublic/MCVE/manifest.json" finds the file fine...what's going on?我收到 404 - 但“ls /Users/joepublic/MCVE/manifest.json”发现文件很好......发生了什么?
404: /Users/joepublic/MCVE/manifest.json
The URL http://localhost:9876/Users/joepublic/MCVE/manifest.json
is a 404 error. URL
http://localhost:9876/Users/joepublic/MCVE/manifest.json
是 404 错误。
but "ls /Users/joepublic/MCVE/manifest.json" finds the file fine
但是“ls /Users/joepublic/MCVE/manifest.json”发现文件很好
That is a path on your local file system.这是本地文件系统上的路径。 It is not an HTTP URL served up but the web server that your test running is running.
它不是提供的 HTTP URL,而是运行测试的 Web 服务器。
