Question

我收到错误：收到的文件没有收到 docFile = CrystalReport1.pdf 代码是vb.net

本准则：

      Dim requestBodyStart As String = asciCR + asciLN + asciCR + asciLN + "--BOUNDARY" + asciCR + asciLN + _
            "Content-Type: application/xml" + asciCR + asciLN + _
            "Content-Disposition: form-data" + asciCR + asciLN + _
            asciCR + asciLN + _
            xmlBody + asciCR + asciLN + asciCR + asciLN + "--BOUNDARY" + asciCR + asciLN + _
            "Content-Type: application/pdf" + asciCR + asciLN + _
            "Content-Disposition: file; filename=" + docFile + " \  documentId=1" + asciCR + asciLN + _
            asciCR + asciLN
        Dim requestBodyEnd As String = asciCR + asciLN + "--BOUNDARY--" + asciCR + asciLN + asciCR + asciLN

制作此请求：

   --BOUNDARY
Content-Type: application/xml
Content-Disposition: form-data

感谢您的帮助！

我不确定这只是你的帖子的间距问题，但你的开放边界之前有额外的前导空格不应该存在：

   --BOUNDARY
Content-Type: application/xml
Content-Disposition: form-data

我看到的下一个更有可能导致错误的问题是你在Content-Disposition标题中指定filename - 你有转义字符（\）但是缺少实际的转义序列，这意味着你正在转义文件名的第一个字符。

Content-Disposition: file; filename=\CrystalReport1.pdf \  documentId=1

相反，你需要这样的东西：

Content-Disposition: file; filename=\"CrystalReport1.pdf\"; documentid=1

没有收到文件错误
