com.HttpPart.setHeader

Sets a named HTTP multipart header using a string value.

Syntax

setHeader(
   name STRING,
   value STRING )
  1. name specifies the multipart header name.
  2. value specifies the multipart header value (such as HTTP headers).

Usage

Use this method to set HTTP multipart headers.

For instance, when you send a multipart image, it is recommended that you specify the image mime type with this header method. If the image is a png, you have to do part.setHeader("Content-Type","image/png"), which allows the peer to know the format of the attached file it has to process.

Note: In case of related multipart (i.e., the part is multipart/related and set via the com.HttpRequest.setMultipartType("related",NULL,NULL)), it is mandatory to set a unique Content-ID header. To set up a unique Content-ID header, use the security.RandomGenerator.CreateUUIDString method.

In case of error, the method throws an exception and sets the STATUS variable. Depending on the error, a human-readable description of the problem is available in the SQLCA.SQLERRM register. See Error handling in GWS calls (STATUS).

Example

CALL req.setHeader("MyClientHeader","Hello")
