通过 DocuSign Rest API 创建 DocuSign 信封时出错（包含多个文档和多个收件人）

Question

我正在尝试使用 DocuSign REST API 在包含多个文档的 DocuSign 中创建一个信封，我正在使用多部分/表单数据请求，我使用 JSON 来定义信封的属性，我检查了我的 JSON，然后我认为没关系。在此之下，我定义了一个多部分/混合部分，在其中设置文档的标题和 PDF 字节。我收到一个错误的请求错误代码，上面写着“NO_DOCUMENT_RECEIVED”，并有消息“文档元素不包含编码的文档，或者编码有问题。”。我在下面发布了 fiddler 的请求结果：

Answer 1

您不应该需要这些定义第二个边界的行（或对该第二个边界的任何后续引用）：

Content-Disposition: form-data
Content-Type: multipart/mixed; boundary=e8bc9555e9634110bba63547b2552460

尝试删除它（以及所有后续对边界 e8bc9555e9634110bba63547b2552460 的引用），以便您的请求如下所示：
