我正在使用一个API，它接收一个PDF文件并进行一些分析，但我总是收到响应500
最初使用Postman进行了测试，请求通过，接收到带有相应JSON信息的响应200。应该关闭SSL安全性。
然而，当我尝试通过Python执行请求时，我总是得到响应500
我写的Python代码：

import requests

url = "https://{{BASE_URL}}/api/v1/documents"
fin = open('/home/train/aab2wieuqcnvn3g6syadumik4bsg5.0062.pdf', 'rb')
files = {'file': fin}
r = requests.post(url, files=files, verify=False)
print (r)
#r.text is empty

Python代码，由Postman制作：

import requests

url = "https://{{BASE_URL}}/api/v1/documents"

payload = "------WebKitFormBoundary7MA4YWxkTrZu0gW\r\nContent-Disposition: form-data; name=\"file\"; filename=\"aab2wieuqcnvn3g6syadumik4bsg5.0062.pdf\"\r\nContent-Type: application/pdf\r\n\r\n\r\n------WebKitFormBoundary7MA4YWxkTrZu0gW--"
headers = {
    'content-type': "multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW",
    'Content-Type': "application/x-www-form-urlencoded",
    'cache-control': "no-cache",
    'Postman-Token': "65f888e2-c1e6-4108-ad76-f698aaf2b542"
    }

response = requests.request("POST", url, data=payload, headers=headers)

print(response.text)

由于保密性，已将API链接屏蔽为{{BASE_URL}}
Postman回复：

{
    "id": "5e69058e2690d5b0e519cf4006dfdbfeeb5261b935094a2173b2e79a58e80ab5",
    "name": "aab2wieuqcnvn3g6syadumik4bsg5.0062.pdf",
    "fileIds": {
        "original": "5e69058e2690d5b0e519cf4006dfdbfeeb5261b935094a2173b2e79a58e80ab5.pdf"
    },
    "creationDate": "2019-06-20T09:41:59.5930472+00:00"
}

Python的回应：

Response<500>

更新：

尝试了GET请求-工作正常，因为我从它那里收到了JSON响应。我想问题是在发布PDF文件。关于如何将文件发布到API，是否有其他选项？
Postman 回复RAW：

正确的请求

因此，最终-正确的代码如下：

import requests

files = {
    'file': open('/home/train/aab2wieuqcnvn3g6syadumik4bsg5.0062.pdf', 'rb'),
}
response = requests.post('{{BASE_URL}}/api/v1/documents', files=files, verify=False)
print (response.text)
