Question

I’m learning Python and trying to test some rest web_service applications. From the below code what I’m trying to do is to post something and to get the result. When I launch this the console gives me this:

Traceback (most recent call last):
  File "D:\workspaces_branch1\csse120\TestPythonProject\src\UTF-Rest-Client.py", line 9, in <module>
    import restful_lib
ImportError: No module named restful_lib

I think it’s because I don’t have this restful_lib module. where can I get it and how can I install it?
also, I want to know if the launch is good how can I get the returned data?

import argparse

#additional lib, need installation (see README)
import restful_lib

testQueueId = 0

# FUNCTIONS

#generate POST content

def postContent():

        xmlData = "<testQueueRequestByNewnancy>"+ \
        "<nancy>"+ \
        "<nancyTargetId>" + args.nancyTargetID + "</nancyTargetId>"+ \
        "<nancyUrl>" + args.nancyUrl + "</nancyUrl>"+ \
        "<nancyVersion>" + args.nancyVersion + "</nancyVersion>"+ \
        "<projectId>" + args.projectID + "</projectId>"+ \
        "<MumID>" + args.MumID + "</MumID>"+ \
        "</nancy>"+ \
            "<user>"+ \
                "<id>" + args.userID + "</id>"+ \
             "</user>"+ \
         "</testQueueRequestByNewnancy>"   

        printVerbose('xmlData =' + xmlData)
        return xmlData

#this function will print text only if verbose is on

def printVerbose(text):
    if args.verbose:
        print(text)


#this function will instruct scheduler through REST API call to do new tests

def callRestApi(content):
    printVerbose('calling REST scheduler API...')

    #recreate complete URL
    base_url = 'http://localhost:8080/test'
    #ensure http:// is at the beginning
    if (base_url[0:7].lower() != 'http://'):
        base_url = 'http://' + base_url
        printVerbose('url is ' + base_url)
        conn = restful_lib.Connection(base_url, username=args.login, password=args.password)
        headers = {'content-type':'text/json', 'accept':'text/json'}
        conn.request_post("/bynewnancy", args={'q': 'Test'}, headers=headers)
        #conn.request_get("/bynewnancy", args=content, returns=conn.ret, headers={'Accept': 'text/json'})

    args = parser.parse_args()


    postContent = postContent()

    print('----==============================---- ')

Answer 1

The restful_lib comes from http://code.google.com/p/python-rest-client, but its last change is 4 years ago, so I wouldn’t suggest using this package.

I would strongly recommend the requests library for such a task. A POST request with XML data would simply look like this:

requests.post(url, data=my_xml_string)
