标题中显示的边界似乎不是您实际使用的边界标记。@Iridium是的，它很旧……我的错误……我编辑了它……仍然没有work@Iridium+每个部分标题不应有任何空白/空行，除非（准确地）在其末尾有一行，并且主要内容类型标题应全部为一行（首选）或者连续行（无空行/空行），每一行以空格开头。这些是基本的MIME，与SMIME或CBSA没有任何关系；请参阅RFCs或维基百科。此外，您的签名部分明显错误；没有二进制签名（不推荐使用，这里使用base64更好）恰好是EDI文本——尽管这会/将给出一个完全不同的错误。@dave_thompson_085实际上我已经尝试过你提到的不同缩进和间距，但仍然不起作用。尽管我一直在编码签名部分。你说得对，我必须对签名使用二进制编码。您能建议任何Java库这样做吗（我已经试过Base64了）。我还需要将EDI字符串编码为7位。你能指出任何一个Java库都可以做到这两种功能吗？“尝试不同”是非常模糊的，但是当网站回答“无法解析[作为]多部分”时，你所做的一切都是错误的。rfc3851 3.4.3.3所示格式正确。EDI（通常）是ISO 646，它已经是一个7位代码了，您的示例肯定是这样的。Base64内置于8以上的所有java（se）版本中；请参阅IDE中java.util.Base64的javadoc。但是签名的问题不仅仅是编码问题；正如我所说的，该值显然是错误的（顺便说一句，即使是错误的大小；PKCS7/CMS分离签名也不会是128字节）。
