InboundMultiPart

InboundMultiPart

The InboundMultiPart handler is used to send and receive MIME multipart content.

Refer to 5.1.6 Web Browser Content.

Command Keyword Value Developer notes for Command/Keyword/Value RECEIVE HANDLER   InboundMultiPart FILE value Conditional. Name of INPUT tag. FIELD value Conditional. Name of INPUT tag. FILENAME value Conditional. Name of INPUT tag. #JSMMSG field is set to the uploaded filename. ENCODING   Optional. See ENCODING. Used to convert field values. NUMBERFORMAT   Optional. See NUMBERFORMAT. TO value Conditional. File path to receive content. APPEND *YES Optional. Append content to existing file. *NO Default.

A web browser can send content using the multipart/form-data format.

 

<FORM METHOD="POST" ACTION="http://lansa01/cgi-bin/jsmdirect?upload" ENCTYPE="multipart/form-data">
<INPUT NAME="COMPANY" TYPE="TEXT" SIZE ="30"/>
<INPUT NAME="FILE1" TYPE="FILE" SIZE ="60"/>
<INPUT NAME="FILE2" TYPE="FILE" SIZE ="60"/>
<INPUT NAME="FILE3" TYPE="FILE" SIZE ="60"/>
<INPUT TYPE="SUBMIT" VALUE="Send order"/>
</FORM>

 

If the specified FILE, FIELD or FILENAME component does not exist then a command status of NOT_EXIST is returned.

If the FILE component does exist but has not been used then NOT_EXIST is also returned.

Example

Receive content from a Web browser post.

 

RECEIVE HANDLER(InboundMultiPart) FIELD(COMPANY)

 

RECEIVE HANDLER(InboundMultiPart) FIELD(COMPANY) ENCODING(MS932)

 

In the following example the file selected as FILE2 is uploaded to the location and new name given in TO parameter.

 

RECEIVE HANDLER(InboundMultiPart) FILE(FILE2) TO(/image-upload/photo.jpeg)

 

In this example it is the name of the FILE2 (i.e. C:\images\holiday.jpeg) selected in the browser that is passed to the LANSA function (i.e. holiday.jpeg).

 

RECEIVE HANDLER(InboundMultiPart) FILENAME(FILE2)

 

When the SEND command of this content handler is executed the following steps occur:

Use the working list argument to create a MIME MultiPart response.

The name value pair data and the file data are passed using a list argument.

The first field of the list contains the component's content type of FIELD or FILE.

The second field contains the component's name.

The third field contains the component value or the component file path.

An optional fourth field controls how the file contents are MIME encoded. Possible values are 8bit or base64. The default MIME encoding is 8bit. The MIME body part Content-Type is determined by the file extension using the Java Activation Framework.

The field value encoding is determined by the ENCODING keyword.
