Yahoo梦幻足球API的Start参数对返回结果无影响的问题求助

我现在的核心需求是通过Yahoo梦幻足球API拉取所有球员的数据。我知道Yahoo限制单次请求最多返回25个球员，之前了解到可以通过修改Start参数然后循环请求的方式来获取完整数据集，但实际测试下来发现这个方法行不通——不管我把Start设为0、25还是2500，返回的球员数据完全一模一样。

我构造请求URL的代码是这样的：

url = f"{self.base_url}/league/{self.league_id}/players;status=A;start={start},count=25"

以下是我的完整脚本，麻烦帮我排查下问题所在：

import os
import requests
from requests_oauthlib import OAuth2Session
import webbrowser
import xml.etree.ElementTree as ET
import csv
import json

class YahooFantasyAPI:

    def __init__(self):
        self.client_id = os.getenv('API_KEY')
        self.client_secret = os.getenv('API_SECRET')
        self.redirect_uri = 'https://localhost/'
        self.league_id = os.getenv('league_id')
        self.base_url = 'https://fantasysports.yahooapis.com/fantasy/v2'
        self.token = None
        self.oauth = OAuth2Session(self.client_id, redirect_uri=self.redirect_uri, scope='openid')
        self.state = None
        self.item_dict = {}

    def authenticate(self):
        # Step 1: Get authorization URL and state
        authorization_url, self.state = self.oauth.authorization_url(
            'https://api.login.yahoo.com/oauth2/request_auth'
        )
        print(f"Please go to this URL and authorize access: {authorization_url}")
        webbrowser.open(authorization_url)

        # Step 2: User pastes the redirected URL with the code
        redirect_response = input("Paste the full redirect URL here: ")
        print(f"Redirect URL: {redirect_response}")

        # Step 3: Verify that the state parameter from the response matches the one in the request
        if self.state not in redirect_response:
            raise ValueError(f"State in the response does not match the original state. Response state: {redirect_response}")

        print(f"State during token request: {self.state}")

        # Step 4: Fetch the token, ensuring that the state is passed correctly
        self.token = self.oauth.fetch_token(
            'https://api.login.yahoo.com/oauth2/get_token',
            authorization_response=redirect_response,
            client_secret=self.client_secret,
            state=self.state  # Explicitly pass the state value
        )
        print("Authentication successful!")

    def get_players(self):
        item_dict = {}
        if not self.token:
            raise ValueError("Authenticate first by calling the authenticate() method.")

        done = False
        start = 1
        while(not done) :
            # Define the endpoint URL to get league players
            url = f"{self.base_url}/league/{self.league_id}/players;status=A;start={start},count=25"    

            print(url)

            headers = {
                'Authorization': f"Bearer {self.token['access_token']}",
                'Accept': 'application/xml'  # Expect XML response
            }

            response = self.oauth.get(url, params={'format': 'json'})

            # Print the status code and response content to debug
            print(f"Response Status Code: {response.status_code}")
            print(f"Content-Type: {response.headers.get('Content-Type')}")
            # print(response.content)

            with open('all.json', 'a') as csvfile:
                csvfile.write(response.text)
                csvfile.close()

            item_dict = json.loads(response.text)

            numPlayersInResp=len(item_dict['fantasy_content']['league'][1]['players'])   
            # print(item_dict)
            print(numPlayersInResp)

            start += 25

            if numPlayersInResp < 25:
                done = True
