Python requests gives SSL unknown protocol
提问by pyg
I am trying to send a request to an API I have set up on an AWS machine.
我正在尝试向我在 AWS 机器上设置的 API 发送请求。
The code I use is as follows:
我使用的代码如下：
import requests
import json
report_dict = {
"client_name": "Wayne Enterprises",
"client_id": 123,
"report_type": "api_testing",
"timestamp_generated": "2015-07-29T11:00:00Z",
"report_data": {"revenue": 9000.00}
}
report_json = json.dumps(report_dict)
resp = requests.post("https://my-url.com:8080/my-api/reports", data=report_json,verify=False)
Doing this, I get:
这样做，我得到：

raise SSLError(e, request=request)
requests.exceptions.SSLError: [SSL: UNKNOWN_PROTOCOL] unknown protocol (_ssl.c:5

But when I send the request as http instead of https, it (usually) works fine. I've found some evidence that this can have to do with proxy servers, but I am not using one. Are there any other potential reasons for this error? This is a website only available on my company's local network, if that's relevant.
但是当我将请求作为 http 而不是 https 发送时，它（通常）工作正常。我发现了一些证据表明这可能与代理服务器有关，但我没有使用代理服务器。此错误是否还有其他潜在原因？这是一个仅在我公司的本地网络上可用的网站（如果相关）。

My guess is that you are trying the same port 8080 for http and https. But, servers usually listen on a single port either for http or https and not both. This means that if your client is trying to start the TLS handshake needed for https against this port it will get a plain error message back. The client then tries to interpret this error message as TLS and returns some weird error messages, because the response is not TLS at all.
我的猜测是您正在为 http 和 https 尝试相同的端口 8080。但是，服务器通常在单个端口上侦听 http 或 https，而不是同时侦听两者。这意味着，如果您的客户端尝试针对此端口启动 https 所需的 TLS 握手，它将收到一条简单的错误消息。然后客户端尝试将此错误消息解释为 TLS 并返回一些奇怪的错误消息，因为响应根本不是 TLS。
