Question

我在Java中使用REST API用于DocuSign。我尝试使用文档嵌入签名（最终进入我的页面中的iframe），而不是像API演练中那样嵌入模板。通过这里看，我读到这可以通过合并来自embeddedSigning和requestSigning API演练的代码来完成，但我很难做到这一点。现在我觉得我已经接近了，但却发现了一个我不知道它在说什么的错误。

    url = baseURL + "/envelopes";   // append "/envelopes" to baseUrl for signature request call

我收到了这个错误：

步骤3：为嵌入式签名生成URL令牌... API调用失败，返回的状态为：411 [致命错误]：1：50：publicId和systemId之间需要空格。

我对这一切都很陌生，所以任何有关我应该如何嵌入文件签名的帮助都将非常感激。错误：＆＃39; publicId和systemId之间需要空格。＆＃39;

Answer 1

根据RFC 2616标准，HTTP错误411表示缺少Content-Length标头。尝试将Content-Length标头添加到请求中，并将其设置为您正在构建的请求正文的大小。
