AWS API 网关 returns 403 一些和 200 一些

Question

我有一个 api 网关端点，对我来说 returns 200，但是当它被第三方调用时，他们得到 403。

我通过 curl 请求和 python 请求并获得 200

Bash:

curl -X POST -v --http1.1 https://939pd1ndql.execute-api.us-east-1.amazonaws.com/default/bitbucket-events

Python

requests.post('https://939pd1ndql.execute-api.us-east-1.amazonaws.com/default/bitbucket-events',

每个请求我得到 200 个响应。

但是，当第三方调用端点时，他们会得到

HTTPSConnectionPool(host='939pd1ndql.execute-api.us-east-1.amazonaws.com', port=443): Max retries exceeded with url: /default/bitbucket-events (Caused by ProxyError('Cannot connect to proxy.', error('Tunnel connection failed: 403 Forbidden',)))

第三部分是 bitbucket - 我正在尝试创建 bitbucket 应用程序（实际上只是一个 JSON 有效负载告诉 bitbucket 创建一个 webhook）：

我无法控制 bitbucket 如何执行请求，而且请求非常不透明，但我将其指向 ngrok 并拦截了它发出的请求：

POST /default/bitbucket-events HTTP/1.1
Host: 939pd1ndql.execute-api.us-east-1.amazonaws.com

bitbucket 发送的请求中没有任何内容看起来会导致此问题。

我从 curl 命令得到的响应是：

我现在已经将 api 网关下放为一个模拟端点，returns 200 响应：

并且我已将日志记录设置为非常响亮：

但我只看到日志条目是我发出的 curl 和 python 请求的结果。 bitbucket 请求不会生成日志行。

这是否意味着 bitbucket 请求在我的 api 网关处理请求之前被 AWS 拒绝了？我没有启用 WAF

如你所知，我运行没主意了。

我复制了您的设置，但使用了我自己的 API 网关。虽然我能够安装该应用程序，但强烈怀疑它与您的 API 网关设置有关。

我使用的是完全相同的应用程序描述符，只有 URL 不同。

{
    "key": "codereview.doctor.staging",
    "name": "Code Review Doctor Staging",
    "description": "Target lambdas with 'staging' version alias",
    "vendor": {
        "name": "Code Review Doctor",
        "url": "https://codereview.doctor"
    },
    "baseUrl": "https://fj7987nlx3.execute-api.ap-southeast-1.amazonaws.com",
    "authentication": {
        "type": "jwt"
    },
    "lifecycle": {
        "installed": "/default/bitbucket-events",
        "uninstalled": "/default/bitbucket-events"
    },
    "modules": {
        "webhooks": [
            {
                "event": "pullrequest:created",
                "url": "/default/bitbucket-events"
            },
            {
                "event": "pullrequest:updated",
                "url": "/default/bitbucket-events"
            },
            {
                "event": "pullrequest:fulfilled",
                "url": "/default/bitbucket-events"
            }
        ]
    },
    "scopes": ["account", "repository", "pullrequest"],
    "contexts": ["account"]
}

我的 API GW POST 配置看起来和你的完全一样，所以不同之处可能在其他地方。

请注意，我已经删除了我的 API GW 阶段，因此您暂时无法使用我的进行测试。
