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.newContext().

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.newContext(). Such APIRequestContext object will have its own isolated cookie storage.

      Whether to ignore HTTPS errors when sending network requests. Defaults to false.

    • maxRedirects number (optional) Added in: v1.26#

      Maximum number of request redirects that will be followed automatically. An error will be thrown if the number is exceeded. Defaults to 20. Pass 0 to not follow redirects.

dispose​

Added in: v1.16 apiRequestContext.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 its resources, calling any method on disposed APIRequestContext will throw an exception.

使用方式

await apiRequestContext.dispose();
await apiRequestContext.dispose(options);

參數

form.set('name', 'John');
form.append('name', 'Doe');
// Send two file fields with the same name.
form.append('file', new File(['console.log(2024);'], 'f1.js', { type: 'text/javascript' }));
