Javascript 为什么我的json响应被解析为空数组？

所以这很难向我解释，但我使用httpclient从后端检索信息。我从他们那里得到了这个json响应

现在，问题是路径roomTypes=>rooms被解析为一个空数组[]

因此，我试着用相应的模型做

post

，但没有成功

现在，我尝试获取文本响应，然后使用javascript解析它。这最终导致了混乱，因为如果i console.log它直接工作，但如果我使用变量它将不工作：

            const reserv = JSON.parse(reservations);
            console.log(JSON.parse(reservations));
            console.log(reserv);

产出：

最糟糕的是，我无法从浏览器在控制台中复制它。因为它能完美地解析

如果您能给我提些建议，我将不胜感激

谢谢

调用类：

constructor(private http: HttpClient, private configuration: Configuration) {
}        
    this.service.DoNonCachedSearch(requProv).toPromise().then(function (reservations: any)  {
                const reserv = JSON.parse(reservations);
                console.log(JSON.parse(reservations));
                console.log(reserv);
            });

在职期间：

                DoNonCachedSearch(request) {
    return this.http
               .post(
                   this.configuration.apiUrlBase +
                   'DoNonCachedSearch'
                   request, {responseType: 'text'},
               );

}

输出： 你试过了吗

 DoNonCachedSearch(request) {
    return this.http
               .post(
                   this.configuration.apiUrlBase +
                   'DoNonCachedSearch'
                   request, {responseType: 'text'},
               ).then(res => res.json());

}

对我来说，这似乎是一个编码问题。您的字符串似乎包含Unicode字符。如果它们被解释为ASCII，解析器可能会被它绊倒。

所以我似乎在访问另一个正在修改的组件中的变量

谢谢大家的帮助

尝试执行HttpPost调用。从Angular 2和更高版本来看，它很好用 可见的。无需转换为承诺并继续进一步的逻辑

在您的服务中，请使用以下代码

 public DoNonCachedSearch(request: any): Observable<any> {
    const url = `${this.configuration.apiUrlBase}DoNonCachedSearch`;
    return this.http.post(url, request,{responseType: 'text'});
  }

angular将自动处理JSON的解析

希望这能解决您的问题。

HttpClient

默认情况下将数据解析为JSON。您不需要在其上使用

JSON.parse（）

。要消除一些混乱，控制台日志将显示“实时数据”，因为在解析您记录的变量时，它将发生变化。它不一定会告诉你在那个特定的时间点上var是什么。请参阅中的“记录对象”部分，您可以展示有关如何设置“保留”变量的更多代码吗？或者您的http请求代码？当然，将更新问题http.post是可观察的。我不能用它。如果我尝试post（）.toPromise（），然后（res=>res.json（））我会得到错误“String.json（）不是有效的方法”，这是真的对不起

  this.service.DoNonCachedSearch(requProv)    
    .subscribe(data =>
        {
            let responseData= data;
            console.log(responseData);
        });
