Question

我是春天新手。只想知道我们可以验证请求参数密钥。我已经使用了RequestParam，因为例如@RequestParam(value= "sourceType")此处value = "sourceType"是我的密钥，因此如果用户输入的sourcety与给定的密钥不匹配，则会400 404 1}}错误，url中缺少sourceType。而不是给出@Scope("request") @RestController public class GetOperatorSeries{ @RequestMapping(value = "test", method = RequestMethod.GET) public String getOperatorSeries(HttpServletResponse response, @RequestParam(value = "mobno") long mobno, @RequestParam(value = "sourceType") String sourceType, @RequestParam(value = "responseType") String responseType) { }错误，我希望它只在url或无效的sourceType中丢失sourceType？这是我的控制器，

这是我的弹簧配置文件

$.post( "check.php", { user: $("#username").val() }, function (data){
  if(data=='1'){
   //do 1
  }
  elseif(data=='0'){
    //do 0
  }
});

您可以将请求参数声明为可选。然后您可以手动检查它是否存在。根据它，您可以显示自定义错误消息。例如 -

@Scope("request")
@RestController
public class GetOperatorSeries{
@RequestMapping(value = "test", method = RequestMethod.GET)
    public String getOperatorSeries(HttpServletResponse response, @RequestParam(value = "mobno") long mobno,
            @RequestParam(value = "sourceType", required=false) String sourceType,
            @RequestParam(value = "responseType") String responseType, Model model)
{

    if (sourceType == null) {
     model.addAttribute("errorMessage", "Source Type is missing");
     return "viewName"; // Now show the error message in view. You can also add this error as flash attribute. You can also show a new error page.


    }

}
