有时候会遇到这种情况,在a函数调用完之后再调用b函数接口,这时候就要用到angular http同步请求,下面是一种案例:
//getDetails public async getLocationDetails(): Promise<any>{ let customBody = { "appID" : APP_CONFIG['appID'], "apiVersion" : 2, "eventID" : atob(sessionStorage.getItem('lyc_event_id')), } const locationDetailsRes=await this.httpService.callEMP(environment.API.getEventInfo,customBody).toPromise() if(locationDetailsRes["status"] == '0'){ /** * 0 is mean success. other status value is mean error **/ sessionStorage.setItem('currentLocationName',locationDetailsRes['event']['eventName']) }else{ this.snackBar.open(this.translateService.instant('General.Error.something_went_wrong_text'), '×', { panelClass: 'error', verticalPosition: 'top', duration: 5000 }); } }
public async onLoginFormSubmit() { await this.getLocationDetails(); }
await会阻断后面函数的执行,直到当前函数执行完毕
