REST URL Encode Path Parts and Query Params

See more REST Examples

When passing a path to a Chilkat REST function, the path parts and query params should be URL encoded. This example explains.. Chilkat2-Python

import sys
import chilkat2

success = False

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

# This example demonstrates how to URL encode the path passed to a REST function.
# It is demonstrated with an Amazon SP API GET request to get details about a listings item for a selling partner.
# See https://developer-docs.amazon.com/sp-api/docs/listings-items-api-v2021-08-01-reference#getlistingsitem

rest = chilkat2.Rest()

# Connect to the REST server.
bTls = True
port = 443
bAutoReconnect = True
success = rest.Connect("sellingpartnerapi-eu.amazon.com",port,bTls,bAutoReconnect)

rest.ClearAllQueryParams()
rest.AddQueryParam("marketplaceids","XYZABC123")
rest.AddQueryParam("includedData","offers")

rest.AddHeader("x-amz-access-token","YOUR_ACCESS_TOKEN")

authAws = chilkat2.AuthAws()
authAws.AccessKey = "YOUR_AWS_APP_ID"
authAws.SecretKey = "YOUR_AWS_APP_SECRET_KEY"
authAws.Region = "eu-west-1"
authAws.ServiceName = "execute-api"
rest.SetAuthAws(authAws)

# The path that is passed to FullRequestNobBody

# Here's a sample path that is not yet URL encoded.
path = "/listings/2022-07-01/items/ABCDEFGHIJ/100x100_28g_LANCETS(BOXED)"

# The path passed to FullRequestNoBody needs to have the parts URL-encoded.
# The "/" chars are not URL encoded, but the individual path parts should be URL encoded.
# For example:  /listings/2022-07-01/items/ABCDEFGHIJ/100x100_28g_LANCETS%28BOXED%29

# In this case, we'll prepare the path like this:
sbPath = chilkat2.StringBuilder()
sbPath.Append("100x100_28g_LANCETS(BOXED)")
# URL encode the contents of the sbPath.
sbPath.Encode("url","utf-8")
# Prepend the remaining which does not need to be URL encoded.
sbPath.Prepend("/listings/2022-07-01/items/ABCDEFGHIJ/")

print("URL encoded path: " + sbPath.GetAsString())

responseJson = rest.FullRequestNoBody("GET",sbPath.GetAsString())
if (rest.LastMethodSuccess != True):
    print(rest.LastErrorText)
    sys.exit()

print(responseJson)
print("----")
