Java 屏幕签名文档未出现，且事件=ttl\u已过期

您好，我尝试使用DocuSign的嵌入式签名功能对文档进行签名，但当我发送请求时，屏幕签名文档不会出现，它会将我重定向到URL参数为event=ttl\u expired的页面

---

我知道，对于URL令牌，ttl（生存时间）=5分钟，有人能帮我吗？

URL令牌仅在5分钟内有效。如果您被重新定向到URL参数为event=ttl_expired的屏幕，则表示您正试图从过期的URL令牌访问签名工作流

当URL令牌过期时，您需要生成一个新的令牌。你看过DocuSign的API演练吗？DocuSign的restapi有9个常见用例，其中一个用于嵌入式签名。每个演练都有代码，向您展示如何用6种不同的语言（PHP、JavaScript、Java、C#、Objective-C、Python）完成该任务

有关漫游，请参见此处：

例如，由于PHP很容易从命令行运行，因此这里有一个完整的PHP程序，用于生成用于签名的有效URL令牌，该程序取自嵌入式签名API演练。只需从您的帐户输入您的凭据和有效的模板Id，这将适用于您：

<?php

// Input your info:
$integratorKey = '...';
$email = '...@....com';
$password = '...';
$name = "John Doe";

// copy the templateId of an existing template here
$templateId = "C9D9D181-CE57-.....................";

// construct the authentication header:
$header = "<DocuSignCredentials><Username>" . $email . "</Username><Password>" . $password . "</Password><IntegratorKey>" . $integratorKey . "</IntegratorKey></DocuSignCredentials>";

您可能需要对您的问题进行一些改进。很难理解您想要修复的内容和问题所在。您提到Java，但没有显示任何与正在发生或应该发生的事情相关的代码。我理解并重新表述了他们的问题。。。
