Python codes to get API content and send POST

request.py

import requests
import json

# an example url, which actually returns JSON
url = "https://crawler.goodfind.com.tw/d/E0pvWZk1"

# this is how to do HTTP GET
r = requests.get(url)

# print returned content
print(r.text)

# if the returned content is in JSON format
j = json.loads(r.text)

# now 'j' object is in JSON format, you can retrieve data in hash way
len(j["items"])  # get size
j["items"][0]


# this is how to send a form POST with values and files
files = {'upload_file': open('README.md','rb')}
values = {'field_name_1': 'value_1', 'field_name_2': 'value_2'}

# change url to some address you want to send HTTP POST
url = "http://somesite.com/post_here"
r = requests.post(url, files=files, data=values)



# suppose we want to send data asynchronously
import grequests
urls = [
    'http://www.heroku.com',
    'http://python-tablib.org',
    'http://httpbin.org',
    'http://python-requests.org',
    'http://fakedomain/',
    'http://kennethreitz.com'
]
rs = (grequests.post(url, files=files, data=values) for url in urls)
ret = grequests.map(rs)
print(ret)
