Javascript AngularJSON未到达php

我遇到了以下问题，我有一个发出http请求的服务，当我尝试获取响应时会抛出一个解析器错误，这是因为响应在尝试解析响应时没有准备好

这是密码

simpafAPIservice.getSimulacao($stateParams.id).success(function(response){
         console.log(JSON.stringify(response[0].info));
         $scope.simuladorInfo.cliente = response[0].cliente;
         $scope.simuladorInfo.info = JSON.parse(response[0].info);
         console.log(JSON.stringify(response[0].info));
         setTimeout(function(){
             for(var i=0;i<$scope.simuladorInfo.info.simuladores.length;i++){
                 $scope.addDataGraphic(i);
             }
         },100);
     });
}

正如您所看到的，当我回显$info时，它不会返回任何内容，一个空字符串，但在data.config.params中，我得到了所有参数。有人知道为什么会发生这种情况吗？

根据，$http.success在第一个参数中返回数据，只有当活动transformResponse能够检测到适当的格式时，数据才会转换为JSON：

角度变换提供以下默认变换：

响应转换 $httpProvider.defaults.transformResponse和 $http.defaults.transformResponse：

如果检测到XSRF前缀，请参阅安全注意事项 下一节。如果检测到JSON响应，则使用 JSON解析器

如果您的服务器响应的是空字符串，这里就是这种情况 然后它将不会被检测为JSON对象，并将保持为空字符串

检查您的服务器响应，它可能在没有正文和错误状态的情况下响应。如果您从不同的域请求数据，即使它最终是同一台服务器，也要注意一件事。

您的代码看起来正常，这就是从成功的代码中获得承诺并执行代码。我认为不应该使用setTimeout，而应该使用$timeout，它将在超时完成时运行$digest cycle

代码

A可能就是你要找的。谢谢，那个链接帮了大忙。我会试试这个。最后的问题是另一个，我将JSON存储在数据库中，但当JSON包含非常多的信息时，它不会到达php，有人知道为什么吗？但这只发生在在线上，当我在本地主机上工作时，它工作正常。您的状态如何？500?
