APIエンドポイントを指定してログインしてトークンを取得するにはどうすればよいですか？

Question

import requests,json 

payload = { 
    'username': 'employee', 
    'userpassword': 'abc123' 
} 

login_route = '/eNextWebAPI/login' 
url = 'https://lb-clus-08-01.mycompany.local/myinstance' 


with requests.Session() as s: 
    p = s.post(url, data=payload) 
    print(p.text)

あなたのエンドポイントが信頼できないSSL証明書を使用しているので、理由があります。 これをテスト目的で使用している場合は、メソッドをポストするための引数を追加することで、すぐに回避することができます。

with requests.Session() as s: 
    p = s.post(url, data=payload, verify=False) 
    print(p.text) 

しかし、理想的には有効な証明書を取得する必要があります。グーグルで質問するか、この回答を確認してください。Where could I buy a valid SSL certificate?
