seems to work fine Technically you can pass x:Object as constructor argument. x:Object corresponds to System.Object which does have default constructor. So if you have

code :

 public class MyClass {
     public MyClass(object arg) {

     }
 }

<my:MyClass>
  <x:Arguments>
    <x:Object />
  </x:Arguments>
</my:MyClass>

new MyClass(new object());

<my:MyClass>
  <x:Arguments>
    <x:String>string</x:String>
  </x:Arguments>
</my:MyClass>

new MyClass("string");

hope this fix your issue In your service, you are returning an object with only one property data, which is still an object, not an array.
Try returning res.data:

code :

getProducts(): Observable<Products[]> {
  return this.http.get('http://localhost:8000/api/products')
  .map(res => {
      return res.data;
  })

around this issue Try something like this where you create the object in your response
component.ts

code :

export class MatchComponent implements OnInit {
_postArrayMatch: match[];
newArr: Array<Object> = [];

 constructor(public router:Router, private matchService: MatchService, 
 private route: ActivatedRoute) {}

 ngOnInit(){
   this.getMatchId();
 }

 getMatchId() :void {
  this.route.params.forEach((params: Params)=> {
  let id = +params['id'];



  this.matchService.getMatch(id).subscribe(
    resultArray => {
      this._postArrayMatch = resultArray;
      const keys = Object.keys(this._postArrayMatch) // new stuff starts here
      for(let i = 0; i < keys.length; i++) { 
        newArr.push(this._postArrayMatch[keys[i]]);
        newArr[i]['team'] = keys[i];
      }
    },
    error => console.log("Error ::" + error))
  })
 }

 <div *ngFor="let post of newArr">
  <p> {{post.team}}: {{post.name}}</p>
 </div>

wish help you to fix your issue This is because the response you get from the Weather API is an object an not an Array. Therefore it is not iterable.
Updated

code :

<button (click)="getWeather()">clcik me</button>
<h2 *ngFor="let data of Data | keyvalue">{{data.key}}: {{data.value}}</h2>

<button (click)="getWeather()">clcik me</button>
<h2>Current temperature: {{Data.main.temp}}</h2>
<h2>Wind speed: {{Data.wind.speed}}</h2>

it fixes the issue The problem is that you assign the result of the subscribe call to the teams property:

code :

this.teams = this.playersService.fetchTeams(this.year).subscribe(...);

this.playersService.fetchTeams(this.year).subscribe(data => {
  this.teams = data;
});

will be helpful for those in need I don't have a solution but I can try to explain what the problem is, or at least why it isn't working in your case. Although there's couple of solutions at the end that may or may not work..
