Question

有人能告诉我为什么在Fiddler的请求正文中看到引号而我的服务栈请求字段中没有？

POST http://10.255.1.180:8087/testvariables/new/ HTTP/1.1

{"Field":{"Id":67,"Name":"Brightness Reversion","Header":"Brightness Reversion.","Format":"#0.0","Uom":"%","Precision":0,"MapId":8083,"IsMappedToCustomer":false}}

从Typescript / Angular2调用

let body = JSON.stringify(certField);    
let headers = new Headers({ 'Content-Type': 'application/json;charset=utf-8' });

let requestoptions: RequestOptions = new RequestOptions({
            method: RequestMethod.Post,
            url: this._certFieldsUrl + 'new/',
            headers: headers,
            body: '{"Field":'+body+'}'
        })
return this._http.request(new Request(requestoptions))
            .toPromise()
            .then(function (response) {
                return response.json() as CertFieldSaveResponse;
            })
            .catch(this.handleError);

请求类

public class CertFieldUpdateRequest : IReturn<TestVariableResponse>
    {
        public string Field { get; set; }

    }

POST方法

    public object Post(CertFieldUpdateRequest request)
    {
                log.Debug(request.Field);
       ....
    }

在服务内部，在POST方法中，request.Field的值为：

    {Id:67,Name:Brightness Reversion,Header:Brightness Reversion.,Format:#0.0,Uom:%,Precision:0,MapId:8083,IsMappedToCustomer:false}

因为你的身体实际上是一个完整的json对象而不是json对象中的字符串。所以：

   let requestoptions: RequestOptions = new RequestOptions({
        method: RequestMethod.Post,
        url: this._certFieldsUrl + 'new/',
        headers: headers,
        body: {Field : JSON.stringify(body)}
    })

或者让您的代码类具有属性：

   public class CertFieldUpdateRequest : IReturn<TestVariableResponse>
   {
    public Field Field { get; set; }

   }

   public class Field
    {
        public int Id { get; set; }
        public string Name { get; set; }
        public string Header { get; set; }
        public string Format { get; set; }
        ///etc...
    }
