Demonstrates how to add query params for a REST request. Chilkat2-Python

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

# Let's say we want to send a GET request to 
# https://example.com/search?query=hello%20world&category=books&sortBy=price&filterBy=inStock

# Notice that the query parameter values must be URL encoded.

# Let's also explain the parts of the above URL:

#     Scheme: https
#         The scheme specifies the protocol used to access the resource. 
#         In this case, it is "https," which indicates that the resource is accessed using the Hypertext Transfer Protocol Secure (HTTPS).
# 
#     Host: example.com
#         The host part of the URL identifies the domain name or IP address of the server hosting the resource. In this case, "example.com" is the host.
# 
#     Path: /search
#         The path is the specific location or resource on the server that the client wants to access. 
#         In this URL, the path is "/search," indicating that the client is requesting the "search" resource on the server.
# 
#     Query Parameters:
#         Query parameters are used to send additional data to the server as key-value pairs. 
#         They are separated from the path by a question mark ? and each parameter is separated by an ampersand &.
# 
#         The above URL has four query parameters:
#             query=hello%20world: The "query" parameter with the value "hello world". The %20 represents the URL-encoded space character in the value.
#             category=books: The "category" parameter with the value "books".
#             sortBy=price: The "sortBy" parameter with the value "price".
#             filterBy=inStock: The "filterBy" parameter with the value "inStock".

rest = chilkat2.Rest()

# Connect to the REST server.

# The Host part of the URL is passed in the 1st argument.
# The Scheme part of the URL ("https") is indicated by the 2nd and 3rd arguments (port and bTls).
bTls = True
port = 443
bAutoReconnect = True
success = rest.Connect("example.com",port,bTls,bAutoReconnect)

# There are 3 ways to send the above GET request.

# 1) Send the request with path and query params pre-built, where the query param values are URL encoded.
responseJson = rest.FullRequestNoBody("GET","/search?query=hello%20world&category=books&sortBy=price&filterBy=inStock")
if (rest.LastMethodSuccess != True):
    print(rest.LastErrorText)
    sys.exit()

# 2) Pass only the Path part of the URL, and specify the query params separately by calling AddQueryParams beforehand.
#    Again, the query params must be already URL encoded when passed to AddQueryParams
rest.ClearAllQueryParams()
rest.AddQueryParams("query=hello%20world&category=books&sortBy=price&filterBy=inStock")
responseJson = rest.FullRequestNoBody("GET","/search")
# ...
# ...

# 3) Pass each query parameter separately by calling AddQueryParam.  In this case, the query param value should be passed without URL encoding.
#    (ClearAllQueryParams ensures any params set for previous request are cleared.)
rest.ClearAllQueryParams()
rest.AddQueryParam("query","hello world")
rest.AddQueryParam("category","books")
rest.AddQueryParam("sortBy","price")
rest.AddQueryParam("filterBy","inStock")
responseJson = rest.FullRequestNoBody("GET","/search")
# ...
