如何将错误呈现给客户端？AngularJS / WebApi模型状态

呼叫服务器时，请根据对

$http

然后在您的控制器中，我建议在处理显示的错误时将对错误数组的响应展平，如下面的小提琴示例所示：

for (var key in resp.ModelState) {    for (var i = 0; i < resp.ModelState[key].length; i++) {        errors.push(resp.ModelState[key][i]);    }}

放在一起：

// Post the data to the web api/service$http.post(url, data)    .success(successHandler)    .error(function (response) {        // when there's an error, parse the error        // and set it to the scope (for binding)        $scope.errors = parseErrors(response);    });//separate method for parsing errors into a single flat arrayfunction parseErrors(response) {    var errors = [];    for (var key in response.ModelState) {        for (var i = 0; i < response.ModelState[key].length; i++) { errors.push(response.ModelState[key][i]);        }    }    return errors;}
