访问 vi Postman 时 Kong 响应 404

Question

我已经架设了一个API和Kong。我已经成功安装了Kong。事实上，我可以通过 cli 上的 curl 访问我的 APIs。但是，当我使用我一直使用的 Postman 时，我得到了响应

{
  "request_path": "/api/v1/",
  "message": "API not found with these values",
  "request_host": [
    "192.168.33.13"
  ]
}

Ps。我刚接触香港，所以请多多包涵。

当我卷曲 api...

$ curl -i -X GET -H "Host: 192.168.33.10" "http://192.168.33.13:8000/api/v1/"

{"status": 200, "message": 200, "data": "Hello World!", "error": null}

当我尝试使用 Postman 时，我收到了 404 状态响应。有了这个 body

{
  "request_path": "/api/v1/",
  "message": "API not found with these values",
  "request_host": [
    "192.168.33.13"
  ]
}

我是不是漏掉了什么？

免责声明：我使用 Postman 是因为我很懒惰，而且我的客户也大多会使用 Postman。所以不要告诉我改用 curl :)

Answer 1

您需要设置名为 "Host" 的 header 参数，以便 Kong 找到您的 API.

可以看到你的curl命令有这个参数

-H "Host: 192.168.33.10"

Answer 2

刚遇到同样的问题。为了发送到 Kong，您需要添加 Host header，但是 Postman 有一些受限制的 header 被阻止，Host 就是其中之一。您需要下载 Chrome Inspector 发送主机 header。更多细节 - https://www.getpostman.com/docs/requests
