axios请求错误:ECONNREFUSED with Heroku

Question

我试图将我的node.js应用程序部署到Heroku，但是当我试图使后端请求时，我得到一个Error: connect ECONNREFUSED 127.0.0.1:80

我相信我已经正确设置了我的端口:

const port = process.env.PORT || 8000;
const server = app.listen(port, () => {
console.log(`App running on port ${port}`);
});

这是我的axios方法:

exports.home = catchAsync(async (req, res, next) => {
const upcoming = await axios({
method: 'GET',
url: '/api/v1/shifts/upcoming',
params: {
limit: 4,
},
});

这是我的日志:

我注意到当前的URL是完全错误的:

_currentUrl: 'http:/api/v1/shifts/upcoming?limit=4',

由于某些原因没有使用我的heroku url。我被困住了，有人能帮帮我吗?

Answer 1

如果你没有在URL参数中传递绝对URL，如-

{
...
url: 'http://example.org/api/v1/shifts/upcoming', 
...
}

必须传递一个baseUrl参数，如-

{
...
baseUrl: 'http://example.org/api/',
url: 'v1/shifts/upcoming',
...
}

您可以参考axios文档- https://www.npmjs.com/package/axios
