  go-server:
    image: gobuild

    restart: on-failure

我的 docker 个容器

docker ps --format '{{.Names}}'
chapter11_go-server_1
chapter11_kong_1
chapter11_db_1

我正在尝试向 Kong 管理员提出 POST 请求 API，它在端口 8001 上运行。但它失败了。

{
"name": "myapi",
"hosts": "server1",
"": "http://chapter11_go-server_1:3000",
"uris":["/api/v1"],
"strip_uri": true,
"preserve_host": false
}

输出

kong_1             | 172.21.0.1 - - [29/Apr/2019:10:36:58 +0000] "POST /apis HTTP/1.1" 404 23 "-" "PostmanRuntime/7.6.0"
kong_1             | 172.21.0.1 - - [29/Apr/2019:10:47:30 +0000] "POST /apis HTTP/1.1" 404 23 "-" "PostmanRuntime/7.6.0"

如何查明我的 POST 请求是否有问题？

什么是 upstream_url？

Answer 1

根据 Kong 1.0.0 changelog:

The API entity and related concepts such as the /apis endpoint, are removed (deprecated since 0.13.0, March 2018). Use Routes and Services instead.

自从 Kong 1.0 /apis 端点不再可用。因此，您得到了 404 Not found 响应。

要将 API 添加到 Kong，您必须使用 /services 和 /routes。本教程介绍了如何操作：Configuring a Service
