Multipart mixed

Any multipart subtypes that an implementation does not recognize should be treated as being of subtype mixed. All parts of a mixed -replace message have the same semantic meaning. Based on the Mixed Subtype definition that is mentioned in section 5. Any multipart subtypes that an implementation does not recognize must be treated as being of mixed subtype. Mixed Subtype The mixed subtype of multipart is intended for use when the body parts are independent and need to be bundled in a particular order.

Creates a multipart - mixed MIME message with the 1st part containing plain-text, and the 2nd part containing a GIF image. Hi, Can someone please explain the difference between these two mime types? Each body part is delineated by a boundary. The boundary parameter is a text string used to delineate one part of the message body from another. Multipart provides methods to retrieve and set its subparts.

What is the expected behavior? The default multipart subtype is mixed. The use of a Content-Type of multipart in a body part within another multipart entity is explicitly allowed. In such cases, for obvious reasons, care must be taken to ensure that each nested multipart entity must use a different boundary delimiter. See Appendix C for an example of nested multipart entities.

In particular, each of the parts is an alternative version of the same information. Systems should recognize that the content of the various parts are interchangeable. The mail contains an HTML body and an attachment. The get_NumParts() method returns but the getBodyDecoded() returns an empty string.

Below is an example of the mail I am trying to parse. Within a single operating environment the links are often file names, such links may be represented within a MIME message using content-IDs or the value of some other Content- headers. I am sending the below SMTP message through curl to recipients. On mail it display as the text followed inline with the html. On Outlook Version the HTML is send as an attachment, not inline.

This form contains a text input control and a file input control. A multipart message is different from the other five. Each part can have its own content type. This provider helps with the creation of multipart HTTP messages.

You typically use these requests for file uploads and for transferring data of several types in a single request (for example, a file along with a JSON object). Any inline attachments referenced from the body. The subpart is delimited by the boundary defined in the Content-Type header.

Used on the body itself, Content-Disposition has no effect. This is the peace of code could probably be improve. This header is neede otherwise the request will fail. A subclass of MIMEBase , this is an intermediate base class for MIME messages that are multipart.

Optional _subtype defaults to mixed , but can be used to specify the subtype of the message. The multipart mime format is used to pass lists of content bodies. Multiple content bodies are embedded in one message. HTML Form documents and is generally used to upload files. Since this should be used with a larger number of users, my idea is to make a REST web service with Web API and serve an MJPEG stream to every user.

The MIME parser assumes that a Content-Type value with type = multipart introduces a multipart MIME document, and rejects such a value if it does not contain a valid boundary parameter. The value of the boundary parameter defines the separator between message parts in a multipart message. The part containing this multipart , if known.
