Using requests in Python to process GET request - python

I posted another question but made a bit of a mess of it in the comments section. Basically, I am trying to use the requests library in Python in order to accomplish what I normally would by using CURL in order to process a GET request to an API. From what I have learned from a very helpful person here, I can process the request, as well as the authorisation header by doing the following:
Original CURL Command that I would normally use:
curl -X GET -H 'Authorization: exapi:111:58d351234e1a:LA2' 'http://api.example.com/v1.14/user?id=1234'
This is the Python code I am using for my script:
import requests
import json
url = "http://api.example.com/v1.14/user?id=1234"
headers = {"Authorization": "exapi:111:58d351234e1a:LA2"}
response = requests.get(url, headers=headers)
print response.json
However, when I run my code, I receive bound method response.json of <response [200]> instead of data that I was expecting from the GET. Can someone help me figure out what I am doing wrong here? I am guessing that I am doing something wrong with my header but I am not sure.

As #juanpa.arrivilaga has already mentioned and as the printed message clearly says, you need to call the bound json method. The source of confusion is likely from content, which is an attribute.
response.json() # method
response.content # attribute

How about using json module explicitly:
data = json.loads(response.text)
print data

Curl works but python requests doesn't

When I do curl, I get a response:
root#3d7044bac92f:/home/app/tmp# curl -H "Content-type: application/json" -X GET https://github.com/timeline.json -k
{"message":"Hello there, wayfaring stranger. If you\u2019re reading this then you probably didn\u2019t see our blog post a couple of years back announcing that this API would go away: http://git.io/17AROg Fear not, you should be able to get what you need from the shiny new Events API instead.","documentation_url":"https://developer.github.com/v3/activity/events/#list-public-events"}
However, when I do python requests to the same URL I get a status 410.
import requests
headers = {
'Content-type': 'application/json',
}
r = requests.get('https://github.com/timeline.json')
print r.json
root#3d7044bac92f:/home/app/tmp# python rest.py
<bound method Response.json of <Response [410]>>
What gives?
The host is a standard Ubuntu docker image and only installed Curl and some python modules. Python -V is 2.7
Note: I looked at this question but I can't telnet into above server so that solution doesn't apply to me:
Curl works but not Python requests
You've made at least two errors in your program.
1) You haven't specified the data= or headers parameters to the requests.get() call. Try this:
r = requests.get('https://github.com/timeline.json', data=data, headers=headers)
2) .json is a method, not a data attribute of the response object. As a method, it must be called in order to be effective. Try this:
print r.json()

Trouble getting data from REST http service using requests package

This works fine, I can get data returned:
r = urllib2.Request("http://myServer.com:12345/myAction")
data = json.dumps(q) #q is a python dict
r.add_data(data)
r=urllib2.urlopen(r)
But doing the same with requests package fails:
r=requests.get("http://myServer.com:12345/myAction", data=q)
r.text #This will return a message that says method is not allowed.
It works if I make it a post request: r=requests.post("http://myServer.com:12345/myAction", data=json.dumps(q))
But why?
According to the urllib2.urlopen documentation:
the HTTP request will be a POST instead of a GET when the data parameter is provided.
This way, r=urllib2.urlopen(r) is also making a POST request. That is why your requests.get does not work, but requests.post does.
Set up a session
import session
session = requests.Session()
r = session.get("http://myServer.com:12345/myAction", data=q)
print r.content (<- or could us r.raw)

Converting url encode data from curl to json object in python using requests

What is the best way to convert the below curl post into python request using the requests module:
curl -X POST https://api.google.com/gmail --data-urlencode json='{"user": [{"message":"abc123", "subject":"helloworld"}]}'
I tried using python requests as below, but it didn't work:
payload = {"user": [{"message":"abc123", "subject":"helloworld"}]}
url = https://api.google.com/gmail
requests.post(url, data=json.dumps(payload),auth=(user, password))
Can anybody help.
As the comment mentioned, you should put your url variable string in quotes "" first.
Otherwise, your question is not clear. What errors are being thrown and/or behavior is happening?

Executing URLs in Python similar to curl in Linux - JenkinsAPI

I am trying to trigger some builds using a shell script by doing the following :
export url='http://test.com';
export job_name='MY_JOB_NAME';
jso="{\"parameter\": [{\"name\":\"BRANCH\",\"value\":\"master\"}, {\"name\":\"GITURL\",\"value\":\"https://github.test.com/test/test.git\"}]}";
curl $url/job/$job_name/build --data-urlencode json="$jso";
This works fine, but when I try to convert it to a python equivalent, it doesn't seem to trigger the URL:
import requests
import json
url='http://test.com/job/MY_JOB_NAME/build'
params={'name':'release_1.5', 'GITURL':'https://github.test.com/test/test.git'}
payload = json.dumps(params)
resp = requests.get(url=url, data=payload)
This executes without any error, but it does not trigger a build on my CI machine.
There are quite a few things you're doing wrong here. The first thing which I hope is apparent is that the JSON data you're sending is completely different.
Beyond that, the primary issue you're having here is that your curl is doing a POST with urlencoded data in the BODY, and your python request is doing a GET with urlencoded data as separate parameters in the url. Change your .get to a .post, and the params= to data= and you should be a whole lot closer to your intended goal.
resp = requests.post(url=url, data={'json':payload})
Also note, I embedded your payload into a key as json, as that's what is happening in your curl. I'm not fully aware of your implementation details, but I hope that this helped put you on the right track.
Add the content-type to the header of the request, i.e.:
headers = {'content-type': 'application/json'}
...
resp = requests.get(url=url, params=payload, headers=headers)

sending data parameters to rest api using python-requests

I am trying to call rest api by sending json data. The curl command is pretty straight forward but only problem that I am facing is with "--data" parameter.
For curl, the data is sent as follows:
curl -X POST -H <headers> --data 'params={...}' <url>
I am not able to figure out how to send the --data parameter with the name 'params='attached to it using python-requests.
Also while making GET requests, there are a lot of options which I have to send along with the curl requests(-O ,-J, -v, -G,-L).
I wanted to know how to supply these additional parameters using python-requests.
Thanks.
curl is a very rich library that has gone far way after a lot of developments in last decades. Compare to the curl, python's requests library is still a baby. So you can not expect all the functionalities of curl in requests. You'll only get the major functionalities of curl in your requests.
Now come to your question. If you want to send the json data through a variable, then the basic POST operation(content-type application/x-www-form-urlencoded) will do.
payload = {'params': json_string}
r = requests.post("http://url/post", data=payload)
But if you want to POST the data as json object with header content-type as json, then you have to use this
headers = {'content-type': 'application/json'}
r = requests.post(url, data=json_string, headers=headers)
In Curl the param -L means for following the redirection. You can achieve it with allow_redirects=True parameter:
r = requests.post(url, data=json_string, headers=headers, allow_redirects=True)
Help yourself to find your needs from the requests document.
