I am having some issues dealing with the requests library. I am debugging api calls through postman, and was able to get the following request to work there, but could not reproduce a successful request call in python. I was also able to get it to work in curl. I posted the relevant bits

Can anyone explain why

This curl request works

curl --request GET 'https://stats.nba.com/stats/playerdashboardbygeneralsplits?PlayerID=1628369&TeamID=0&MeasureType=Base&PerMode=PerGame&PlusMinus=N&PaceAdjust=N&Rank=N&LeagueID=00&Season=2020-21&SeasonType=Regular+Season&PORound=0&Outcome=&Location=&Month=0&SeasonSegment=&DateFrom=&DateTo=&OpponentTeamID=0&VsConference=&VsDivision=&GameSegment=&Period=0&ShotClockRange=&LastNGames=0%0A' --header 'Host:  stats.nba.com' --header 'User-Agent:  Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:61.0) Gecko/20100101 Firefox/61.0' --header 'Accept:  application/json text/plain */*' --header 'Accept-Language:  en-USen;q=0.5' --header 'Referer:  https://stats.nba.com/' --header 'Accept-Encoding:  gzip deflate br' --header 'Connection:  keep-alive' --header 'x-nba-stats-origin:  stats' --header 'x-nba-stats-token:  true'

But this identical request in python does not

import requests

url = "https://stats.nba.com/stats/playerdashboardbygeneralsplits?PlayerID=1628369&TeamID=0&MeasureType=Base&PerMode=PerGame&PlusMinus=N&PaceAdjust=N&Rank=N&LeagueID=00&Season=2020-21&SeasonType=Regular+Season&PORound=0&Outcome=&Location=&Month=0&SeasonSegment=&DateFrom=&DateTo=&OpponentTeamID=0&VsConference=&VsDivision=&GameSegment=&Period=0&ShotClockRange=&LastNGames=0"

headers = {
    'Host': 'stats.nba.com',
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:61.0) Gecko/20100101 Firefox/61.0',
    'Accept': 'application/json text/plain */*',
    'Accept-Language': 'en-USen;q=0.5',
    'Referer': 'https://stats.nba.com/',
    'Accept-Encoding': 'gzip deflate br',
    'Connection': 'keep-alive',
    'x-nba-stats-origin': 'stats',
    'x-nba-stats-token': 'true'
}

response = requests.get(url, headers=headers)

results in

I have seen similar issues posted here before, but I couldn't find any that seemed applicable to my problem. Does anyone see a difference between the requests or could explain why these (seemingly) identical requests would fail?

  • Your Accept* headers look wrong to me. Shouldn't they be comma-separated lists?

  • @Rup the curl one has the same Accept headers, and I also tried making it into a comma-separated list with no luck

  • not sure if this is the case, but some websites (Linkedin is one of them) are using order of headers to detect scraping.

  • OK, fair enough. Can you verify that your Python code is using TLS 1.2+? If that's not it, I'd try making both requests in as verbose a mode as you possibly can, to try and see what exactly both clients are sending.

I debugged it. This is a good question. Apparently, changing the 'Accept': 'application/json text/plain */*' to 'Accept': 'application/json' did the trick.

I ran the script changing it.

import requests

url = "https://stats.nba.com/stats/playerdashboardbygeneralsplits?PlayerID=1628369&TeamID=0&MeasureType=Base&PerMode=PerGame&PlusMinus=N&PaceAdjust=N&Rank=N&LeagueID=00&Season=2020-21&SeasonType=Regular+Season&PORound=0&Outcome=&Location=&Month=0&SeasonSegment=&DateFrom=&DateTo=&OpponentTeamID=0&VsConference=&VsDivision=&GameSegment=&Period=0&ShotClockRange=&LastNGames=0%0A"

headers = {
    'Host': 'stats.nba.com',
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:61.0) Gecko/20100101 Firefox/61.0',
    'Accept': 'application/json',
    'Accept-Language': 'en-USen;q=0.5',
    'Referer': 'https://stats.nba.com/',
    'Accept-Encoding': 'gzip,deflate br',
    'Connection': 'keep-alive',
    'x-nba-stats-origin': 'stats',
    'x-nba-stats-token': 'true'
}

response = requests.get(url, headers=headers)
print(response.status_code)
print(response.json())

Output:

  • Interesting. Do you have an explanation to why this worked?

  • Probably the server is accepting only application/json. I assume the server is doing an equality check.
