this.strategyService.getAllstrategys（...）。subscribeは関数ではありません

Question

私は角テストのテストを行ったときにこのエラーを検出しました。フォローは私のコードの一部です。 失敗しました：。this.strategyService.getAllstrategys（...）購読するには、機能 TypeError例外ではありません：。this.strategyService.getAllstrategys（...）購読されていない機能

//In strategyTables.component.ts 
 
getStrategys():void{ 
 
    this.strategyService.getAllstrategys(this.strategyname,this.isuseragent,this.iscookie,this.currentpage,this.itemsPerPage,this.sorts).subscribe(data=>{ 
 
     this.totalItems=data.json().totalElements; 
 
     this.currentPage=data.json().number+1; 
 
     this.strategys=data.json().content; 
 
     for(var i=0;i<data.json().totalPages;i++){ 
 
      this.totalnumbers[i]=i+1; 
 
     } 
 
     }, 
 
     error => console.log(error),()=>console.log("获取到所有的urlmng")); 
 
    }

getAllstrategysのあなたのモック実装は0の代わりにプレーンなオブジェクトを返します。。あなた簡単にObservable.ofを使用してObservableにプレーンなオブジェクトを変換することができます

import { Observable } from "rxjs/Rx"; 
// ... 

getAllstrategys(strategyname: string, isuseragent: string, iscookie: string, page: number, 
    size: number, sorts: string) { 
    var mockData = { 
     "content": [{ 
      "id": 11, 
      "strategyname": "strategy11", 
      "isuseragent": "是", 
      "depth": 2, 
      "downloadDelay": 3, 
      "iscookie": "yes", 
      "agent": null, 
      "starttime": "" 
     }, 
     // ...  
     ], 
     "last": false, 
     "totalPages": 2, 
     "totalElements": 8, 
     "size": 5, 
     "number": 0, 
     "sort": [{ 
      "direction": "DESC", 
      "property": "id", 
      "ignoreCase": false, 
      "nullHandling": "NATIVE", 
      "ascending": false 
     }], 
     "first": true, 
     "numberOfElements": 5 
    } 
    return Observable.of({ 
     json:() => mockData 
    }); 
}
