axios 请求错误：使用 Heroku ECONNREFUSED

时间：2021-02-10 17:01:32

标签： node.js mongodb heroku deployment axios

我曾尝试将我的 node.js 应用程序部署到 Heroku，但是当我尝试发出后端请求时，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',

出于某种原因，它没有使用我的 heroku 网址。我被困在这个问题上，有人可以帮助我吗？

答案 0 :(得分：1)

如果您没有在 url 参数中传递绝对网址，例如 -

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

你必须传递一个 baseUrl 参数，比如 -

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

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