Tutorial 17 – Parse json and Post API Request using Playwright Python
What you will Learn in this blog:
Read/parse json data
Post request
POST Request (Register successful)
Code snippets
Read/parse json data
Go to https://reqres.in/api/users/
Notice that 6 users are listed on this page
To parse the json, we can simply use json method
Execute the command, notice that we get the output data in json format, showing the same 6 user ids
Let us comment line#7.
Let us say we want to fetch the json output of a specifc user id, we can do that by asking user a question and than fetching the details
When we execute, notice below that we get the details of respective user id
Post request
Launch https://reqres.in/
Notice below that we need to pass some body as part of POST request (unlike a GET request)
Let us now see how to construct a ‘Post’ request using Playwright python.
During runtime, we will be asking user the new ‘name’ he wants to post into the server (line#15) and will then catch this name in ‘user’ variable (line#16)
Next, in line#19, we are creating a standard ‘headers’ tag and this would mean that “we would be posting a json request”
In line#20 (see above), we are actually creating a post request by posting the json data that we creared in line#16.
Finally, in line#21, we are printng the content
Let us execute.
Notice that the new user gets posted and created in the server and a unique ‘id’ is assigned to this new user at runtime
Let us also print the status code(line#22)
Execute and notice below that status code 201 (successful post) is returned from the server side
Let us comment line#16 and add lines#17 and 18. So basically, this time, we are posting the user’s ‘job’ as well
Execute
POST Request (Register successful)
Let us now see another example of a POST request.
Below we can see that, in the response, we get a token
Let us change the end point and post the data as shown below. We have used the same email id and password seen above
Save and run.
Observe below that token gets generated (that means user registration was successful) and our test passes
Code snippet (post data)
import requests
from playwright.sync_api import Playwright, sync_playwright, expect
def run(playwright: Playwright) -> None:
#resp = requests.get("https://reqres.in/api/users/")
#id = input("Which user id should i get for you? ")
#resp = requests.get(f"https://reqres.in/api/users/{id}")
#print(resp.json())
#Post
name = input("What should be the name of new user? ")
#user = {"name": name}
job = input("What should be the job of new user? ")
user = {"name": name, "job": job}
headers = {"Content-type": "application/json"}
resp = requests.post("https://reqres.in/api/users", json=user, headers=headers)
print(resp.content)
print(resp.status_code)
with sync_playwright() as playwright:
run(playwright)
Code snippet (Register successful)
import requests
from playwright.sync_api import Playwright, sync_playwright, expect
def run(playwright: Playwright) -> None:
#resp = requests.get("https://reqres.in/api/users/")
#id = input("Which user id should i get for you? ")
#resp = requests.get(f"https://reqres.in/api/users/{id}")
#print(resp.json())
#Post
email = "eve.holt@reqres.in"
password = "cityslicka"
user = {"email": email, "password": password}
headers = {"Content-type": "application/json"}
resp = requests.post("https://reqres.in/api/login", json=user, headers=headers)
print(resp.content)
print(resp.status_code)
with sync_playwright() as playwright:
run(playwright)
