    response: Partial<ResponseForRequest>,
    priority?: number,
  ): Promise<void>;
}

参数

🌐 Parameters

范围 🌐 Parameter	类型 🌐 Type	描述 🌐 Description
response	Partial<ResponseForRequest>	满足请求的响应。 🌐 the response to fulfill the request with.
priority	number	（可选） 如果提供，则使用合作处理规则解决拦截。否则，拦截会立即解决。 🌐 (Optional) If provided, intercept is resolved using cooperative handling rules. Otherwise, intercept is resolved immediately.

返回:

Promise<void>

附注

🌐 Remarks

要使用此功能，应通过 Page.setRequestInterception() 启用请求拦截。

🌐 To use this, request interception should be enabled with Page.setRequestInterception().

如果未启用请求拦截，则立即抛出异常。

🌐 Exception is immediately thrown if the request interception is not enabled.

示例

🌐 Example

使用 404 响应满足所有请求的示例：

🌐 An example of fulfilling all requests with 404 responses:

await page.setRequestInterception(true);
page.on('request', request => {
  request.respond({
    status: 404,
    contentType: 'text/plain',
    body: 'Not Found!',
  });
});

注意：不支持对 dataURL 请求模拟响应。对 dataURL 请求调用 request.respond 将不会执行任何操作。

🌐 NOTE: Mocking responses for dataURL requests is not supported. Calling request.respond for a dataURL request is a noop.
