Method and system for sending session tokens through passive clients and storage medium

A session token can be requested to be sent to a first computing service from a second computing service, and a first computing service can receive the requested session token from the second computing service. The first computing service can send a message that includes the session token through a passive client to the second computing service. The second computing service can receive the messagethat includes the session token from the passive client, and the second computing service can verify that the message is valid. This verification of the validity of the message can include verifyingthat the session token received back from the passive client matches the session token the second computing service sent to the first computing service. 会话令牌可被请求从第二计算服务发送到第一计算服务，并且第一计算服务可接收来自第二计算服务的所请求的会话令牌。第一计算服务可通过被动客户端向第二计算服务发送包括该会话令牌的消息。第二计算服务可接收包括来自被动客户端的会话令牌的消息，并且第二计算服务可验证该消息是有效的。这个对该消息的有效性的验证可包括验证从被动客户端接收回的会话令牌匹配第二计算服务发送到第一计算服务的会话令牌。
