Question

我正在使用提供程序从api获取数据。我需要知道如何将某些数据通过组件传递给提供程序。

在组件中

   constructor(    private activatedRoute: ActivatedRoute, private modalService: NgbModal, private api:ApiService, public httpClient: HttpClient, private spinner: NgxSpinnerService) { 

    this.activatedRoute.params.subscribe(
      params=> {const company_id = params['company_id'];
      console.log(company_id);
      this.company_id = company_id;
      console.log(this.company_id);
    });



if(this.company_id){

  this.api.getSamad(this.company_id);
  this.company = false;

}

else{
   this.company = true;
   this.api.getClaims();
   }


  }

  ngOnInit(){
  console.log(this.company_id);

}

提供者

 constructor(    private activatedRoute: ActivatedRoute, private 
 modalService: NgbModal, public httpClient: HttpClient, private spinner: 
 NgxSpinnerService) { }

getSamad(){

console.log(this.company_id);

this.url = 'http://url.php?offset=0&limit=10&company_id='+this.company_id;

      this.clientData = this.httpClient.get<any>(this.url).
         subscribe(data => {
         console.log(data);
         this.spinner.hide();

         this.data1 = data.records;
         this.data1.forEach(d => this.policy_id.add(d.policy_id));
         console.log(this.userFilter.policy_id);

我需要在提供商控制台中显示this.company_id。

在提供程序中，您是否正在使用this.company_id？然后它将查找提供程序类中定义的company_id局部变量。

在组件中

    private companyId = 1001;
....
    if(this.companyId){
      this.api.getSamad(this.companyId);  
    }

您的提供商类别

constructor(    private activatedRoute: ActivatedRoute, private 
 modalService: NgbModal, public httpClient: HttpClient, private spinner: 
 NgxSpinnerService) { }

public getSamad(company_id: any){

console.log(company_id);
// you cannot type this.company_id as "this" refers to the provider class 
// object not the component.

this.url = 'http://url.php?offset=0&limit=10&company_id='+this.company_id;

      this.clientData = this.httpClient.get<any>(this.url).
         subscribe(data => {
         console.log(data);
         this.spinner.hide();

         this.data1 = data.records;
         this.data1.forEach(d => this.policy_id.add(d.policy_id));
         console.log(this.userFilter.policy_id);

建议点-在声明变量或方法或创建类时，请遵循适当的标准。在此示例中-company_id-> companyId 有关更多信息-https://angular.io/guide/styleguide
