Request module in Python Learn "in the middle"

Installation:

PIP Install requests

Use:

Import requests

HTTP requests: GET, POST, PUT, DELETE, HEAD, OPTIONS

1) Get

res = Requests.get ("Https://github.com/timeline.json")

2) Post

res = Requests.post ("Http://httpbin.org/post");

3) put

res = Requests.put ("Http://httpbin.org/put");

4) Delete

res = Requests.delete ("Http://httpbin.org/delete");

5) Head

res = Requests.head ("Http://httpbin.org/get");

6) Options

res = requests.options ("Http://httpbin.org/get")

Passing parameters for URLs

The requests module provides parameters in the form of a dictionary using the params keyword parameter.

>>> payload = {' Key1 ': ' Value ', ' key2 ': ' value2 '}
>>> res = requests.get ("Http://httpbin.org/get", Params=payload)
>>> Res.url
U ' http://httpbin.org/get?key2=value2&key1=value '

View response Content

>>> res = requests.get ("Http://github.org/timeline.json")
>>> Res.text
U ' {"message": "Hello there, Wayfaring stranger. If You\u2019re Reading this and you probably didn\u2019t see we blog post a couple of years back announcing that this AP I would go Away:http://git.io/17arog fear not, you should is able to get what is need from the shiny new Events API Inst EAD. "," Documentation_url ":" Https://developer.github.com/v3/activity/events/#list-public-events "} '

The requests module automatically decodes the content from the server, You can use Res.encoding to view the encoding, and, if you need to, request can also use a custom encoding and register with the codes module, so that you can easily use the name of the decoder as the res.encoding value

>>> res.encoding
' Utf-8 '
>>> res.encoding = "gbk2312"

Get the contents of a response in JSON format

>>> res = requests.get ("Http://github.org/timeline.json")
>>> Res.json ()
{u ' documentation_url ': U ' https://developer.github.com/v3/activity/events/#list-public-events ', u ' message ': U ' Hello there, Wayfaring stranger. If You\u2019re Reading this and you probably didn\u2019t see we blog post a couple of years back announcing that this AP I would go Away:http://git.io/17arog fear not, you should is able to get what is need from the shiny new Events API Inst EAD. '}

The original should be content

>>> res = requests.get ("Http://github.org/timeline.json")
>>> Res.raw
<requests.packages.urllib3.response.httpresponse Object at 0x0000000002f31550>
>>> Res.raw.read (10)
‘‘

Custom Request Headers

>>> Import JSON
>>> url = ' Https://api.github.com/some/endpoint '
>>> payload = {' Some ': ' Data '}
>>> headers = {' Content-type ': ' Application/json '}

The POST request parameter is this:

>>> payload = {' Key1 ': ' value1 ', ' key2 ': ' value2 '}
>>> url = "Http://httpbin.org/post"
>>> Res =requests.post (url,data=payload)
>>> Res.text
U ' {\ n ' args ': {}, \ n "Data": "", \ n "files": {}, \ n "form": {\ n "key1": "value1", \ n "key2": "value2" \ n}, \ n "Headers": {\ n "Accept": "*/*", \ n "accept-encoding": "gzip, deflate", \ n "content-length": "All", \ n "content- Type ":" "application/x-www-form-urlencoded", \ n "Host": "httpbin.org", \ n "user-agent": "python-requests/2.10.0" \ n} , \ n "JSON": null, \ n "origin": "218.240.129.20", \ n "url": "Http://httpbin.org/post" \n}\n "
>>> Print Res.text
{
"args": {},
"Data": "",
"Files": {},
"Form": {
"Key1": "Value1",
"Key2": "value2"
},
"Headers": {
"Accept": "*/*",
"Accept-encoding": "gzip, deflate",
"Content-length": "23",
"Content-type": "application/x-www-form-urlencoded",
"Host": "httpbin.org",
"User-agent": "python-requests/2.10.0"
},
"JSON": null,
"Origin": "218.240.129.20",
"url": "Http://httpbin.org/post"
}

Response status Code and response header:

>>> res = requests.get ("Http://httpbin.org/get")

>>> Res.status_code
200
>>> Res.status_code = = Requests.codes.ok
True
>>> res.headers
{' content-length ': ' 239 ', ' Server ': ' Nginx ', ' Connection ': ' keep-alive ', ' access-control-allow-credentials ': ' True ', ' Date ': ' Sun, 09:24:10 GMT ', ' access-control-allow-origin ': ' * ', ' content-type ': ' Application/json '}
>>> Print Res.headers
{' content-length ': ' 239 ', ' Server ': ' Nginx ', ' Connection ': ' keep-alive ', ' access-control-allow-credentials ': ' True ', ' Date ': ' Sun, 09:24:10 GMT ', ' access-control-allow-origin ': ' * ', ' content-type ': ' Application/json '}
>>> res.headers[' Content-type ']
' Application/json '
>>> res.headers.get (' Content-type ')
' Application/json '
>>> res.headers.get (' Connection ')
' Keep-alive '
>>>

Cookies:

Access to Cookies

>>> url = ' Http://example.com/some/cookie/setting/url '
>>> r = requests.get (URL)

>>> r.cookies[' Example_cookie_name ']

Set cookies

>>> url = ' http://httpbin.org/cookies '
>>> cookies = dict (cookies_are= ' working ')

>>> r = requests.get (URL, cookies=cookies)
>>> R.text

' {' "cookies": {"Cookies_are": "Working"}} '
