Create a Post Request using playwright<\/strong><\/p>\n
In this section, we will explore the process of making an API request using Playwright through the POST method.<\/p>\n
Go to https:\/\/reqres.in\/<\/a>\u00a0<\/p>\n
Please note that for the POST request, it is necessary to provide a body as part of the request, see below\u00a0<\/p>\n<\/div>\n
$\"\"$ <\/span><\/div>\n
$\"\"$ <\/span><\/div>\n
\n
Let us explore the process of creating a new user ID using Playwright Java.<\/p>\n
To begin with, create an object of \u2018APIRequestContext<\/em>\u2019<\/p>\n<\/div>\n
$\"\"$ <\/span><\/div>\n
\n
\u00a0Using Map create body of POST request.\u00a0<\/p>\n
The data that we intend to send as part of the POST request will be included in the body<\/p>\n<\/div>\n
$\"\"$ <\/span><\/div>\n
\n
\u00a0After that, we will obtain the text response and assign it to a string variable.\u00a0<\/p>\n
The post() method provided below takes in two parameters: the first parameter represents the uri where we intend to post our data, while the second parameter represents the data itself, which we have previously created<\/p>\n<\/div>\n
$\"\"$ <\/span><\/div>\n
\n
\u00a0At the end, we will print the response in the console\u00a0<\/p>\n<\/div>\n
$\"\"$ <\/span><\/div>\n
\n
\u00a0Execute.<\/p>\n
POST request passes. New user \u2018id\u2019 is created and printed<\/p>\n<\/div>\n
$\"\"$ <\/span><\/div>\n
\n
\u00a0Learn how to parse json<\/strong><\/p>\n
json parser \u2018gson\u2019 can be used to parse json https:\/\/mvnrepository.com\/artifact\/com.google.code.gson\/gson\/2.10.1<\/p>\n<\/div>\n
$\"\"$ <\/span><\/div>\n
\n
\u00a0 Add dependency in xml<\/p>\n<\/div>\n
$\"\"$ <\/span><\/div>\n
\n
\u00a0Save pom.xml<\/p>\n
An instance of Gson is created and the response is passed as an argument to the fromJson()<\/em> method<\/p>\n<\/div>\n
$\"\"$ <\/span><\/div>\n
\n
\u00a0So let us parse id, name, job<\/p>\n<\/div>\n
$\"\"$ <\/span><\/div>\n
\n
\u00a0Code so far is as below<\/p>\n<\/div>\n
$\"\"$ <\/span><\/div>\n
\n
\u00a0Execute the code.\u00a0<\/p>\n
id, name, job gets printed<\/p>\n<\/div>\n
$\"\"$ <\/span><\/div>\n
\n
\u00a0Sample Post Request (Register successful, 200)<\/strong><\/p>\n
Next, we will explore another example of a POST request.\u00a0<\/p>\n
It can be observed in the response below that a token is received<\/p>\n<\/div>\n
$\"\"$ <\/span><\/div>\n
$\"\"$ <\/span><\/div>\n
\n
\u00a0Modify the endpoint and post the data in the following manner. We have utilized the identical email id and password as mentioned above<\/p>\n<\/div>\n
$\"\"$ <\/span><\/div>\n
\n
\u00a0Execute.<\/p>\n
The generation of a token indicates that the user registration process was successful. Also the \u2018id\u2019 gets generated, see below<\/p>\n<\/div>\n
$\"\"$ <\/span><\/div>\n
\n
\u00a0Sample Post Request (Login unsuccessful, 400)<\/strong><\/p>\n
Now, let’s analyze the last scenario<\/p>\n<\/div>\n
$\"\"$ <\/span><\/div>\n
\n
\u00a0Change uri plus other details<\/p>\n<\/div>\n
$\"\"$ <\/span><\/div>\n
\n
\u00a0Execute.<\/p>\n
The console prints error<\/p>\n<\/div>\n
$\"\"$ <\/span><\/div>\n
\n
\u00a0You can try out POST requests in a similar fashion using playwright java.\u00a0<\/p>\n
