使用 Python 请求发送多部分/表单数据时遇到问题

Question

我正在尝试将三个字符串发布到 API/表单。如果您熟悉的话，该 Web 服务称为“Nginx 代理管理器”。它实际上没有 API 文档，但它使用 openapi 3.1.0。我正在尝试发布到此部分：

   "/nginx/certificates/{certID}/upload": {
  "post": {
    "operationId": "uploadCertificate",
    "summary": "Uploads a custom Certificate",
    "tags": [
      "Certificates"
    ],
    "security": [

                },
                "certificate_key": {

                "intermediate_certificate": {
                  "type": "string",
                  "minLength": 1
                }
              }
            }
          }
        }
      }
    }
  }
},

这就是我目前拥有的。我尝试了很多其他方法，这似乎是节省空间最正确的方法：

url = "https://api.example.com/api/nginx/certificates/1/upload"

# This header has been working in other calls.
headers = {
  "Authorization": f"Bearer " + api_key
}

# public, private, and chain are all strings
# I've tried tuples with  None and actual text like "chain.pem"
# I've tried a straight dict without the tuple
files = {
  "certificate": (None, public),
  "certificate_key": (None, private),
  "intermediate_certificate": (None, chain)
}

response = requests.post(url, headers=headers, files=files)
print(print(json.dumps(response.json(), indent=2)))

{
  "error": "No files were uploaded"
}
