Playwright接口测试_发起接口请求

playwright是可以做接口测试的，这个是playwright的优势之一。要做接口自动化测试主要过程就是发起接口请求，接收接口响应，断言。本文我们就来看一下playwright如何发起接口请求。

Playwright下发起接口请求有三种方法，可以通过browser_context.request或page.request发起请求，也可以通过调用api_request.new_context（）手动创建一个新的APIRequest上下文实例发起请求。前两种属于通过浏览器发起请求，需要驱动浏览器。如果不想驱动浏览器直接发起接口请求可以使用第三种。

另外每个Playwright浏览器上下文都有与其关联的APIRequestContext实例，该实例与浏览器上下文共享cookie存储，所以在接口与接口之间不需要手动管理cookie，这一点就跟requests库下的session类的作用一样。

接下来我们以修改密码接口为例来看一下三种接口请求的使用。如下图fiddler的抓包截图，密码修改成功后接口响应为success。

browser_context.request发起请求

api_request_context = context.request # context对象创建接口请求实例
