# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

mime = chilkat.CkMime()

# The contents of this MIME file are shown below, 
# and is also available at https://www.chilkatsoft.com/sampleMime.txt
success = mime.LoadMimeFile("qa_data/mime/sampleMime.txt")
if (success == False):
    print(mime.lastErrorText())
    sys.exit()

# The MIME used in this example has the following nested structure
# 
# multipart/alternative
#     text/plain
#     multipart/related
#         text/html
#         image/jpeg
# 

# Getting the content of a top-level MIME header is easy.
# MIME header fields are case insensitive.
print("Subject = " + mime.getHeaderField("subject"))
print("MIME-Version = " + mime.getHeaderField("mime-version"))

# To get a MIME header in a sub-part, first navigate to it..
