Required request parameter 'id' for method parameter type String is not present

This error message indicates that a required parameter named 'id' is missing in the request being sent to the server.

To resolve this error, you need to check the request being sent and ensure that it includes the 'id' parameter with a valid value. If the 'id' parameter is optional, you may need to modify the server code to handle requests without this parameter.

Required request parameter 'requestUrl' for method parameter type String is not present

根据提供的引用内容，当使用@RequestParam注解接收请求参数时，必须确保请求中包含了对应的参数。如果请求中没有提供该参数，就会出现"Required request parameter 'requestUrl' for method parameter type String is not present"的错误。

以下是一个示例，演示了如何使用@RequestParam接收请求参数，并处理可能出现的缺少参数的情况：

@GetMapping("/example")
public String exampleMethod(@RequestParam("requestUrl") String requestUrl) {
    // 处理请求参数
    // ...
    return "success";
}

在上述示例中，`@RequestParam("requestUrl")`指定了请求参数的名称为"requestUrl"，并将其绑定到方法参数`requestUrl`上。如果请求中没有提供"requestUrl"参数，就会抛出"Required request parameter 'requestUrl' for method parameter type String is not present"的错误。

如果你想要避免出现该错误，可以使用`required`属性来设置参数是否为必需的。例如，将`@RequestParam`注解修改为`@RequestParam(value = "requestUrl", required = false)`，这样即使请求中没有提供"requestUrl"参数，也不会抛出错误。

Required request parameter 'test' for method parameter type String is not present

This error message is often encountered when a web application or API endpoint expects a request parameter called "test" to be provided as part of a request, but the parameter is missing.

To resolve this error, you need to make sure that the request being sent includes a parameter named "test" with a value. Depending on the specific application or API, this may involve updating the request URL or the request body to include the missing parameter.

If you are unsure of how to provide the required parameter, you may need to consult the documentation or support resources for the application or API you are working with.
