1.非自研系统

通过接口，获取第三方系统token，存redis缓存，设计跳转配置，根据获取的配置路由等用户信息来访问第三方系统免登录。（登入校验在第三方系统实现）

/// <summary>
/// 获取OA登录Token
/// </summary>
/// <returns></returns>
public async Task<string> PostOaAcessTokenAsync(string loginid)
{string resToken = "";var formData = new Dictionary<string, string>{{ "appid", "*************************" },{ "loginid", loginid }};var content = new FormUrlEncodedContent(formData);// 发送POST请求HttpResponseMessage response = await HttpHelper.Client.PostAsync("http://127.0.0.1:8888/ssologin/getToken", content);// 处理响应if (response.IsSuccessStatusCode){// 对成功的响应进行操作var responseContent = await response.Content.ReadAsStringAsync();resToken = responseContent;if (resToken.Contains("has no account:")){throw new UserFriendlyException(UserConst.OA_User_No_Exist);}return resToken;// 域登陆成功}else{// 处理错误throw new UserFriendlyException(UserConst.Login_Error);}}

1.自研系统（OOS机制-单点登录）

通过调整自研系统登入接口参数，添加token字段，由门户创建token，这边按照token值来判断是否不走正常账号密码登入，直接通过token值调用门户接口校验，如果校验成功则质检进入自研系统。

public async Task SSOLoginValidationAsync(string token, Action<UserEntity> userAction = null)
{var user = new UserEntity();// 发送POST请求HttpResponseMessage response = await HttpHelper.Client.PostAsync("http://127.0.0.1/prod-api/auth/get-token/" + token, null);// 处理响应if (response.IsSuccessStatusCode){// 对成功的响应进行操作var responseContent = await response.Content.ReadAsStringAsync();var jObject = JObject.Parse(responseContent);var bo = jObject["succeeded"].Value<bool>();if (bo){string UserCode = jObject["data"].Value<string>();// 工号if (await ExistAsync(UserCode, o => user = o)){if (userAction is not null){userAction.Invoke(user);return;// 域登陆成功}}throw new UserFriendlyException(UserConst.Login_User_No_Exist);}else{// 处理域登陆失败throw new UserFriendlyException(UserConst.Auth_User_Token_Invalid);}}else{// 处理错误throw new UserFriendlyException(UserConst.SSO_Token_Err);}
}
