Question

这是我在angular2项目中的服务，我想在服务中使用create方法来调用我的控制器。

 create(maillingId: string, name: string, phone: string): Observable<void> {      
    var rp = new RecipientDto(maillingId, name, phone);

    console.log(JSON.stringify(rp));
    console.log(this.apiUrl);
    console.log(this.headers); 

    return this.http.post(this.apiUrl, JSON.stringify(rp), { headers: this.headers })
        .do(null,
        () => {
        })
        .map<any>(response => { });

}

这是我打印出来的这是我可行的邮递员电话最后是我的控制器代码

 [HttpPost]
    public IActionResult Post([FromBody]RecipientDto recipientDto)
    {
        MailingList ml = _repository.Get<MailingList>(recipientDto.MaillingId);

        if (ml != null)
        {               
            var rp = new Recipient(Guid.NewGuid());             
            rp.IsActivated = true;
            rp.Name = recipientDto.Name;
            rp.PhoneNumber = recipientDto.Phone;
            ml.Recipients.Add(rp);        
            return Ok();
        }
        return HttpNotFound();          
    }

有一点需要注意的是，当调用我的前端创建方法时，没有fiddler记录。

同样的删除问题（也不要调用api），但getAll（）是可行的

 getAll(id:string): Observable<Recipient[]> {       

    return this.http.get(`${this.apiUrl+'/'+id}`)
        .map<any>(res => <any>res.json())
        .map(a=> <Recipient[]>a);;

}

和我的控制器获取

 [HttpGet("{mlId}")]
    public IEnumerable<Recipient> Get(string mlId)
    {         
        List<Recipient> list = _repository.Get<MailingList>(mlId).Recipients;

        return list;
    }

我在这里有一个工作岗位样本：

override func viewDidLoad() {
    super.viewDidLoad()

    self.getAPI1()
    self.getAPI2()
    self.getAPI3()
}

func getAPI1() {
    do {
         // try ... Get API Process
    } catch {
         let alertView = UIAlertView(title: "ERROR", message: "There is an error on getAPI1()", delegate: nil, cancelButtonTitle: "OK")
         alertView.show()
    }
}

func getAPI2() {
    do {
         // try ... Get API Process
    } catch {
         let alertView = UIAlertView(title: "ERROR", message: "There is an error on getAPI2()", delegate: nil, cancelButtonTitle: "OK")
         alertView.show()
    }
}

func getAPI3() {
    do {
         // try ... Get API Process
    } catch {
         let alertView = UIAlertView(title: "ERROR", message: "There is an error on getAPI3()", delegate: nil, cancelButtonTitle: "OK")
         alertView.show()
    }
}

为什么http.post没有以角度2调用我的控制器
