# This example assumes Chilkat HTTP to have been previously unlocked.
# See Global Unlock Sample for sample code.

http = chilkat2.Http()

req = chilkat2.HttpRequest()
req.HttpVerb = "POST"
req.ContentType = "multipart/form-data"
req.Path = "/v2.7/me/photos"

# Use the previously obtained access token.
# Note: The publish_actions scope is required to upload a photo.
req.AddHeader("Authorization","Bearer FACEBOOK-ACCESS-TOKEN")

# Send an "Expect: 100-continue" header in the request.
# This causes the HTTP server to end a 100-continue response
# immediately after receiving the HTTP header.  The client
# (Chilkat) will receive this intermediate response, and if
# it's not an error response, it knows that the HTTP server will
# accept the data that is forthcoming.
# The alternative is to get an error response after trying to upload
# the entire contents of the files.
req.AddHeader("Expect","100-continue")

# Set a photo caption.
req.AddParam("caption","Here are some penguins!")

# Additional parameters can be added to the request by 
# calling AddParam once per parameter.  
# See https://developers.facebook.com/docs/graph-api/reference/user/photos
# for more information about other optional parameters.

# Indicate the local file to be uploaded.
success = req.AddFileForUpload("source","qa_data/jpg/penguins2.jpg")
if (success != True):
    print(req.LastErrorText)
    sys.exit()

# Upload the image file..
# resp is a CkHttpResponse
resp = http.SynchronousRequest("graph.facebook.com",443,True,req)
if (http.LastMethodSuccess != True):

    sys.exit()

# Examine the response body:
responseJson = resp.BodyStr
print(responseJson)

# The response contains JSON, such as this:
# {"id":"10210224963435862","post_id":"10224048320139890_10210224963435862"}
