Selenium IDE 中的 API 测试

Question

如何利用Selenium IDE进行API测试。即，将请求推送到服务器并获取响应。

Answer 1

这可以使用 Javascript - XMLHttpRequest 方法来完成。

创建请求，设置标头和其他参数，然后使用正文命中服务器。

命令：

Execute Script

目标：

var req = new XMLHttpRequest();
var url = '<URL of PAI to test>';
var method = Method to test (GET/POST/PUT/DELETE)>';
req.setRequestHeader('Content-type', 'application/json');
req.open(method, url, false);
req.send(<{REQUEST BODY}>);

价值：

<Any variable name to store response>

Answer 2

这是使用 HTTPClient 库的 Get 调用请求。
