APIRequestContext

This API is used for the Web API testing. You can use it to trigger API endpoints, configure micro-services, prepare environment or the service to your e2e test.

Each Playwright browser context has associated with it APIRequestContext instance which shares cookie storage with the browser context and can be accessed via BrowserContext#request or Page#request. It is also possible to create a new APIRequestContext instance manually by calling APIRequest#new_context.

Cookie management

APIRequestContext returned by BrowserContext#request and Page#request shares cookie storage with the corresponding BrowserContext. Each API request will have Cookie header populated with the values from the browser context. If the API response contains Set-Cookie header it will automatically update BrowserContext cookies and requests made from the page will pick them up. This means that if you log in using this API, your e2e test will be logged in and vice versa.

If you want API requests to not interfere with the browser cookies you should create a new APIRequestContext by calling APIRequest#new_context. Such APIRequestContext object will have its own isolated cookie storage.

playwright.chromium.launch do |browser|
  # This will launch a new browser, create a context and page. When making HTTP
  # requests with the internal APIRequestContext (e.g. `context.request` or `page.request`)
  # it will automatically set the cookies to the browser page and vise versa.
  context = browser.new_context(base_url: 'https://api.github,com')
  api_request_context = context.request


  # Create a repository.
  response = api_request_context.post(
    "/user/repos",
    headers: {
      "Accept": "application/vnd.github.v3+json",
      "Authorization": "Bearer #{API_TOKEN}",
    },
    data: { name: 'test-repo-1' },
  )
  response.ok? # => true
  response.json['name'] # => "test-repo-1"

  # Delete a repository.
  response = api_request_context.delete(
    "/repos/YourName/test-repo-1",
    headers: {
      "Accept": "application/vnd.github.v3+json",
      "Authorization": "Bearer #{API_TOKEN}",
    },
  )
  response.ok? # => true
end

delete​

def delete(
      url,
      data: nil,
      failOnStatusCode: nil,
      form: nil,
      headers: nil,
      ignoreHTTPSErrors: nil,
      maxRedirects: nil,
      multipart: nil,
      params: nil,
      timeout: nil)

Sends HTTP(S) DELETE request and returns its response. The method will populate request cookies from the context and update context cookies from the response. The method will automatically follow redirects.

dispose​

def dispose

All responses returned by APIRequestContext#get and similar methods are stored in the memory, so that you can later call APIResponse#body. This method discards all stored responses, and makes APIResponse#body throw "Response disposed" error.

fetch​

def fetch(
      urlOrRequest,
      data: nil,
      failOnStatusCode: nil,
      form: nil,
      headers: nil,
      ignoreHTTPSErrors: nil,
      maxRedirects: nil,
      method: nil,
      multipart: nil,
      params: nil,
      timeout: nil)

Sends HTTP(S) request and returns its response. The method will populate request cookies from the context and update context cookies from the response. The method will automatically follow redirects. JSON objects can be passed directly to the request.

Usage

data = {
  title: "Book Title",
  body: "John Doe",
}
api_request_context.fetch("https://example.com/api/create_book", method: 'post', data: data)

The common way to send file(s) in the body of a request is to encode it as form fields with multipart/form-data encoding. You can achieve that with Playwright API like this:

api_request_context.fetch(
  "https://example.com/api/upload_script",
  method: 'post',
  multipart: {
    fileField: {
      name: "f.js",
      mimeType: "text/javascript",
      buffer: "console.log(2022);",
    },
  },
)

get​

def get(
      url,
      data: nil,
      failOnStatusCode: nil,
      form: nil,
      headers: nil,
      ignoreHTTPSErrors: nil,
      maxRedirects: nil,
      multipart: nil,
      params: nil,
      timeout: nil)

Sends HTTP(S) GET request and returns its response. The method will populate request cookies from the context and update context cookies from the response. The method will automatically follow redirects.

Usage

Request parameters can be configured with params option, they will be serialized into the URL search parameters:

query_params = {
  isbn: "1234",
  page: "23"
}
api_request_context.get("https://example.com/api/get_text", params: query_params)
def head(
      url,
      data: nil,
      failOnStatusCode: nil,
      form: nil,
      headers: nil,
      ignoreHTTPSErrors: nil,
      maxRedirects: nil,
      multipart: nil,
      params: nil,
      timeout: nil)

Sends HTTP(S) HEAD request and returns its response. The method will populate request cookies from the context and update context cookies from the response. The method will automatically follow redirects.

patch​

def patch(
      url,
      data: nil,
      failOnStatusCode: nil,
      form: nil,
      headers: nil,
      ignoreHTTPSErrors: nil,
      maxRedirects: nil,
      multipart: nil,
      params: nil,
      timeout: nil)

Sends HTTP(S) PATCH request and returns its response. The method will populate request cookies from the context and update context cookies from the response. The method will automatically follow redirects.

post​

def post(
      url,
      data: nil,
      failOnStatusCode: nil,
      form: nil,
      headers: nil,
      ignoreHTTPSErrors: nil,
      maxRedirects: nil,
      multipart: nil,
      params: nil,
      timeout: nil)

Sends HTTP(S) POST request and returns its response. The method will populate request cookies from the context and update context cookies from the response. The method will automatically follow redirects.

Usage

JSON objects can be passed directly to the request:

data = {
  title: "Book Title",
  body: "John Doe",
}
api_request_context.post("https://example.com/api/create_book", data: data)

To send form data to the server use form option. Its value will be encoded into the request body with application/x-www-form-urlencoded encoding (see below how to use multipart/form-data form encoding to send files):

form_data = {
  title: "Book Title",
  body: "John Doe",
}
api_request_context.post("https://example.com/api/find_book", form: form_data)

The common way to send file(s) in the body of a request is to upload them as form fields with multipart/form-data encoding. You can achieve that with Playwright API like this:

api_request_context.post(
  "https://example.com/api/upload_script",
  multipart: {
    fileField: {
      name: "f.js",
      mimeType: "text/javascript",
      buffer: "console.log(2022);",
    },
  },
)

put​

def put(
      url,
      data: nil,
      failOnStatusCode: nil,
      form: nil,
      headers: nil,
      ignoreHTTPSErrors: nil,
      maxRedirects: nil,
      multipart: nil,
      params: nil,
      timeout: nil)

Sends HTTP(S) PUT request and returns its response. The method will populate request cookies from the context and update context cookies from the response. The method will automatically follow redirects.
