登录接口有统一认证，访问该登录接口时会跳转到认证界面输入用户名密码
url = "https://auth.xxxxx.com/auth/realms/xxxoa-with-os/protocol/openid-connect/auth?response_type=code&client_id=tests&scope=openid&redirect_uri=https://xxxnew.xxxxx.net"
response = requests.get(url)
if response.status_code == 200:# 从接口的响应中获取重定向的登录接口urlnew_url = re.findall(r'action="(.*?)" method=', response.text)[0]该接口返回内容如下
<div id="kc-form-wrapper" ><form id="kc-form-login" onsubmit="login.disabled = true; return true;" action="https://auth.xxxx.com/auth/realms/xxx-with-os/login-actions/authenticate?session_code=9k3MqNnprJeoM41ugw4B_JvuspNABjCQvzSK-0jXwvg&execution=dfd7b3b2-6595-47d4-b96d-655ff493677e&client_id=test&tab_id=vxRO5NTwtLE" method="post"><div class="form-group"><label for="username" class="control-label">账号</label><input tabindex="1" id="username" placeholder="请输入域账号" class="form-control user-input" name="username" value="" type="text" autofocus autocomplete="off" /></div><div class="form-group"><label for="password" class="control-label">密码</label><input tabindex="2" id="password" class="form-control user-input" placeholder="请输入登录密码" name="password" type="password" autocomplete="off" /></div><div class="form-group login-pf-settings"><div id="kc-form-options"></div><div class=""></div></div>获取到的new_url如下：
https://auth.igwfmc.com/auth/realms/igwoa-with-os/login-actions/authenticate?session_code=ed1wdMv8YR_XHCRRIM3Ua8JNz-pDUAuz6-qIRWuFIfM&execution=dfd7b3b2-6595-47d4-b96d-655ff493677e&client_id=devops&tab_id=jet144uKtaI
返回的url中存在 & 是 HTML 中用于表示字符 & 的转义实体。在处理包含这种 HTML 实体的字符串时，要使用 Python 的 html 模块中的 unescape 函数将其转换回普通字符：
new_url = html.unescape(re.findall(r'action="(.*?)" method=', response.text)[0])对该接口进行请求，获取后续接口需要的内容
