我有一个复合模板，用于发送以下内容：
我收到此错误：执行网络请求时出错。 { ＆＃34; errorCode＆＃34;：＆＃34; UNSPECIFIED_ERROR＆＃34;， ＆＃34; message＆＃34;：＆＃34; Base-64字符数组或字符串的长度无效。＆＃34;我已经确认Base64是4的倍数。我认为问题在于我没有正确的内容类型。我正在使用Nintex和SharePoint将Rest API发送给DocuSign。

答案 0 :(得分：0)
在查看您发布的请求时，我发现了一些事情：
首先，您错误地将指定 documentid = 2 的部分的边界分隔符指定为“ - MY_BOUNDARY - ”
--MY_BOUNDARY--
Content-Type: application/pdf
Content-Disposition: file; filename="{WorkflowVariable:varExhibitAName}"; documentid="2"
通过在此边界字符串的末尾包含 - ，您指示多部分消息的结束，因此DocuSign很可能没有读取任何请求内容这个字符串。我建议将其更改为“ - MY_BOUNDARY”
其次，您为两个文档（documentid = 1和documentid = 2）多次指定文档字节 - 一次作为文档对象的一部分（使用 documentbase64 属性）在每个复合模板中，并再次在多部分请求的其他部分中。我建议从每个Composite Template对象的 document 对象中删除 documentbase64 属性 - 如果你在multipart的其他部分指定文档字节，则不需要它消息。
接下来，如果 CCare_Pledge.pdf 是您正在使用的模板中包含的第一个文档，那么您应该从该复合模板中删除文档属性（对象）对象：
"document": {
"documentId": 4,
"name": "CCare_Pledge.pdf"
}
并删除请求的最后部分：
--MY_BOUNDARY--
Content-Type: application/pdf
Content-Disposition: file; filename="CCare_Pledge.pdf"; documentid="4"
这不是必需的，因为文档来自模板本身，因此您无需在请求中指定文档信息。
最后，确保您的请求以正确的边界终止符字符串结束：
--MY_BOUNDARY--
（这个other post的答案显示了关于边界分隔符的整体请求结构的一个很好的例子。）
一旦实施了这些建议的更改，您的请求结构应如下所示：
--MY_BOUNDARY
