c# - MTOM - 在 VS 2010 中读取时遇到无效的 MIME 内容类型 header

Question

我在磁盘上有一个 MTOM 响应，我正在尝试加载和解析该响应。 在创建 MTOM 阅读器时，我不断收到错误消息。

Invalid MIME content-type header encountered on read.

这是一个错误还是内容类型的 header 真的意味着 Visual Studio 无法理解内容类型？

MIME-Version: 1.0
Content-Type: Multipart/Related;boundary=DeltaSync91ABCB4AF5D24B8F988B77ED7A19733D?MTOM;
    type="application/xop+xml";
    start="<DeltaSyncMTOMFetchResponse@mail.services.live.com>";

    --DeltaSync91ABCB4AF5D24B8F988B77ED7A19733D?MTOM
    content-transfer-encoding: binary
    content-type: application/xop+xml; charset=utf-8; type="application/xop+xml"

这是创建 MTOM 阅读器的简单代码。

XmlDictionaryReader mtomReader = XmlDictionaryReader.CreateMtomReader
            (
             fStream,
             Encoding.UTF8,
             XmlDictionaryReaderQuotas.Max
            );

Answer 1

你的数据有几个问题:

• 您需要在 Content-Type header 中对边界字符串进行编码，因为它包含 ? 字符。
• 第 5 行到末尾是缩进的 - 您需要删除前导空格
• 您缺少结尾的边界字符串

这是对我有用的修改后的内容:

MIME-Version: 1.0
Content-Type: Multipart/Related;boundary="DeltaSync91ABCB4AF5D24B8F988B77ED7A19733D?MTOM"";
    type="application/xop+xml"";
    start="<DeltaSyncMTOMFetchResponse@mail.services.live.com>"";
