使用jquery从ajax响应获取Http状态代码
在我当前的spring项目中,当我向服务器提交表单时,响应由以下方法处理:使用jquery从ajax响应获取Http状态代码,jquery,ajax,spring,spring-mvc,http-status-codes,Jquery,Ajax,Spring,Spring Mvc,Http Status Codes,在我当前的spring项目中,当我向服务器提交表单时,响应由以下方法处理: $('form.form').each(function () { var form = this; $(form).ajaxForm(function (data) { form.reset(); $(".alert-info").find("#alert").html(data); $(".alert-in
$('form.form').each(function () {
var form = this;
$(form).ajaxForm(function (data) {
form.reset();
$(".alert-info").find("#alert").html(data);
$(".alert-info").show();
});
});
在我的控制器中,提交由以下方法处理:
@RequestMapping(value="cadastra", method=RequestMethod.POST)
@ResponseBody
@ResponseStatus(HttpStatus.CREATED)
public void cadastra(@ModelAttribute("object") E object, BindingResult result, @RequestParam(value="file", required=false) MultipartFile file, @RequestParam(value="icone", required=false) MultipartFile icone, @RequestParam(value="screenshot", required=false) MultipartFile screenshot[]) throws IllegalAccessException, IllegalArgumentException, InvocationTargetException, IOException {
serv.cadastra(object);
serv.upload_picture(object, file, "picture");
serv.upload_picture(object, icone, "icone");
}
$(form).ajaxForm(function (data, statusText, xhr) {
alert(xhr.status);
来自控制器的方法的错误响应由此ControllerAdvice类处理:
@ControllerAdvice
@PropertySource({"classpath:error.properties"})
public class GlobalDefaultExceptionHandler {
@Autowired
private Environment env;
@ExceptionHandler(value = Exception.class)
public ModelAndView defaultErrorHandler(HttpServletRequest req, Exception e) throws Exception {
// If the exception is annotated with @ResponseStatus rethrow it and let
// the framework handle it - like the OrderNotFoundException example
// at the start of this post.
// AnnotationUtils is a Spring Framework utility class.
if (AnnotationUtils.findAnnotation(e.getClass(), ResponseStatus.class) != null)
throw e;
// Otherwise setup and send the user to a default error-view.
ModelAndView mav = new ModelAndView();
mav.addObject("exception", e);
mav.addObject("url", req.getRequestURL());
mav.addObject("msg", e.getLocalizedMessage());
mav.setViewName("erro");
return mav;
}
}
我正在寻找一种方法,从jquery代码中的响应(可以是1xx、2xx、3xx、4xx或5xx)读取http状态代码,并根据此代码显示相关消息
在浏览器的网络监视器中,我可以看到一个成功的响应已经有了方法中实现的代码HTTP201;发生错误时,响应的代码应为4xx或5xx,具体取决于触发的异常
通过这种方式,我想知道是否有人可以提示如何修改我的jquery代码和COntrollerAdvice来实现这一点。如下:
$.ajax({
type: "post", url: "/SomeController/SomeAction",
success: function (data, text) {
//...
},
error: function (request, status, error) {
alert(request.responseText);
}
});
e、 g
xhr是XmlHttpRequest的缩写
readyState:值为1:loading、2:loaded、3:interactive、4:complete
状态:HTTP状态号,如404未找到,500内部服务器错误,200:ok(警告:特殊IE问题值:0已取消)
responseText:来自服务器的响应-这可能是您的自定义状态文本(确保状态代码不是OK)
如果要在成功时检查状态,请始终使用:
var jqxhr = $.ajax( "example.php" )
.done(function (data) { alert(data); })
.fail(function (jqXHR, textStatus, errorThrown) { someErrorFunction(); })
.always(function() { alert("complete"); });
另外,请参阅这篇关于成功-错误-完成与失败-总是失败的帖子如果要在页面上设置全局错误处理,请使用ajaxSetup:
看起来您正在使用。如果是这样,回调函数的第三个参数是
xhr
对象,您可以获得如下HTTP状态:
@RequestMapping(value="cadastra", method=RequestMethod.POST)
@ResponseBody
@ResponseStatus(HttpStatus.CREATED)
public void cadastra(@ModelAttribute("object") E object, BindingResult result, @RequestParam(value="file", required=false) MultipartFile file, @RequestParam(value="icone", required=false) MultipartFile icone, @RequestParam(value="screenshot", required=false) MultipartFile screenshot[]) throws IllegalAccessException, IllegalArgumentException, InvocationTargetException, IOException {
serv.cadastra(object);
serv.upload_picture(object, file, "picture");
serv.upload_picture(object, icone, "icone");
}
$(form).ajaxForm(function (data, statusText, xhr) {
alert(xhr.status);
要获取响应中的标题和状态:
$.ajax({
dataType: "json",
url: url,
data: data
}).done(function(rs, textStatus, xhr) {
console.log(xhr.getResponseHeader('X-CUSTOM-HEADER'));
console.log(xhr.status);
});
