angular postman不同的body type需要什么样的请求格式

1. postman的body请求格式为 raw (application/json), 则angular请求方式

      const  headers = new  HttpHeaders().set("Content-Type", "application/json; charset=UTF-8").set("Accept", "*/*" );


let body1 = {
            "access_token"      : environment.token

          }


this.httpClient.post(environment.baseUrl + "ResourceV3/getCategoryList.mvc",body1,{headers})
        .subscribe( (data:any)  => {
          this.spinner.hide();
          if(data["statusCode"] == '0'){
          }else{
            this.snackBar.open('Something went wrong. Please try again later.', '×', { panelClass: 'error', verticalPosition: 'top', duration: 5000 });
          }
        },
        error  => {
          this.spinner.hide();
          this.snackBar.open('Something went wrong. Please try again later.', '×', { panelClass: 'error', verticalPosition: 'top', duration: 5000 });
        });

2. postman的body的请求格式为application/x-www-form-urlencoded，则angular的请求方式为

      const  headers = new  HttpHeaders().set("Content-Type", "application/x-www-form-urlencoded; charset=UTF-8").set("Accept", "*/*" );


  let body1 = new HttpParams({
      fromObject : {
        "access_token"      : environment.TOKEN
      }
    });


    this.httpClient.post(environment.baseUrl + environment.API.getCategoryList,body1,{headers})
    .subscribe( (data:any)  => {
      this.spinner.hide();
      if(data["statusCode"] == '0'){
        this.categoryList=data["returnData"]["datas"]
        this.categoryList   = this.categoryList.sort((a:any, b:any)=>a.name.localeCompare(b.name));
      }else{
        this.snackBar.open('Something went wrong. Please try again later.', '×', { panelClass: 'error', verticalPosition: 'top', duration: 5000 });
      }
    },
    error  => {
      this.spinner.hide();
      this.snackBar.open('Something went wrong. Please try again later.', '×', { panelClass: 'error', verticalPosition: 'top', duration: 5000 });
    });
