为什么通过python请求调用rest api时出现500 Internal Server Error? [英] Why am I getting 500 Internal Server Error when calling post rest api via python request?
问题描述
我正在尝试使用python请求库调用post rest API.当我请求使用邮递员时，我能够得到适当的答复.当我尝试使用python请求库调用它时，出现内部服务器错误.
I'm trying to call a post rest API using python requests library. I'm able to get a proper response when I request using postman. When I tried to call it using python request library I get an internal server error.
import requests
url = "http://192.188.9.146:9886/getcontext/"
payload = "------WebKitFormBoundary7MA4YWxkTrZu0gW\r\nContent-Disposition: form-data; name=\"project\"\r\n\r\ndaynight\r\n------WebKitFormBoundary7MA4YWxkTrZu0gW\r\nContent-Disposition: form-data; name=\"file\"; filename=\"D:\\Downloads\\GTA.Imaging.Services\\GTA.Imaging.Services.Wrapper.TestApp\\PatternMatchingdata\\Go_To_Setting_Screen.jpg\"\r\nContent-Type: image/jpeg\r\n\r\n\r\n------WebKitFormBoundary7MA4YWxkTrZu0gW--"
headers = {
'content-type': "multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW",
'cache-control': "no-cache",
'Postman-Token': "79668e4b-305b-404e-904f-92fc71a12f9f"
}
response = requests.request("POST", url, data=payload, headers=headers)
print(response.text)
这给我以下错误
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN">
<title>500 Internal Server Error</title>
<h1>Internal Server Error</h1>
<p>The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.</p>
当我使用邮递员客户端应用程序时，得到的输出具有预期的响应 邮递员客户端 我究竟做错了什么? 任何指导将非常有帮助，谢谢.
When I use the postman client app I get output with the expected response Postman client what am I doing wrong? Any guidance will be very helpful thanks.
推荐答案
删除payload参数并添加files.请参阅请求文档解释了request.request函数的此选项.
Remove the payload parameter and add files. Refer to requests documentation which explains this option of requests.request function.
import requests
url = "http://192.188.9.146:9886/getcontext/"
files = {'file': open('PATH_TO_FILE\Go_To_Setting_Screen.jpg','rb')}
data = {'project': 'daynight'}
response = requests.request("POST", url, files = files, data = data)
print(response.text)
