我正在使用一个 API,它接收 pdf 文件并进行一些分析,但我总是收到 Response 500
最初使用 Postman 进行测试,请求通过,收到带有相应 JSON 信息的响应 200。应关闭 SSL 安全性。
但是,当我尝试通过 Python 发出请求时,我总是得到 Response 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 生成:
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)
出于保密原因,已将 API 链接屏蔽为 {{BASE_URL}}
邮递员的回复:

},
"creationDate": "2019-06-20T09:41:59.5930472+00:00"
}
Python 的响应:
Response<500>
UPDATE:
尝试了 GET 请求 - 工作正常,因为我收到了来自它的 JSON 响应。我猜问题出在发布pdf文件上。关于如何将文件发布到 API 是否还有其他选项?

正确的要求
所以,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)
