Python Interface Automation 2-send a POST request

Objective

Send POST Request Reference example is very simple, the actual situation is very complex, the first post request must be logged in, but login is the most difficult to handle. The login problem is solved, and it's easy to follow.

First, view official documents

1. Learn a new module, in fact, do not go to Baidu or anything, directly with the help function can see the relevant comments and case content.

>>import Requests

>>help (requests)

2. See the case of Python sending get and post requests

>>> Import Requests
>>> r = requests.get (' https://www.python.org ')
>>> R.status_code
200
>>> ' Python is a programming language ' in R.content
True

... or POST:

>>> payload = dict (key1= ' value1 ', key2= ' value2 ')
>>> r = requests.post (' http://httpbin.org/post ', data=payload)
>>> Print (R.text)
{
...
"Form": {
"Key2": "value2",
"Key1": "Value1"
},
...
}

Second, send the POST request

1. Use the above case, make a simple change, send a POST request

The 2.payload parameter is a dictionary type, which is passed into the form

Third, JSON

The body of 1.post is a JSON type and can also be passed in with JSON parameters.

2. First import the JSON module and use the Dumps method to convert to JSON format.

3. Return the result and upload it to data

Iv. headers

1. Take the Zen Road login as an example, simulate landing, here to add the request head headers, can be used fiddler grab bag

2. Write the request header in a dictionary format

headers = {"User-agent": "mozilla/5.0 (Windows NT 10.0; WOW64; rv:44.0) gecko/20100101 firefox/44.0 ",
"Accept": "Application/json, Text/javascript, */*; q=0.01 ",
"Accept-language": "zh-cn,zh;q=0.8,en-us;q=0.5,en;q=0.3",
"Accept-encoding": "gzip, deflate, BR",
"Content-type": "Application/json; Charset=utf-8 ",
"X-requested-with": "XMLHttpRequest",
"Cookie": "XXX ...", # here the cookie is omitted.
"Connection": "Keep-alive"
}

Five, Zen Road login Reference Code
