Question

我正在尝试将动态参数传递给JSON Post请求，但是当我调试时，我在响应中收到BadRequest格式错误。似乎我无法以正确的样式来格式化“产品”列表，并且输出不像样本格式

我的JSON请求必须类似于以下示例：

    {
     "token": "[access Token]",
     "userid": "[phone number]",
     "transactionid": "a integer number",
     "products": {
     "1221": "100", //product id:product price
     "1575": "200"  //product id:product price
                }
   }

这是我的代码：

      internal void cashback( Order order,string Atoken)
        {
        var client = new RestClient(@"link");
        RestRequest req = new RestRequest();
        var dic = new Dictionary<string, string>();
        foreach (var orderitem in order.OrderItems)
        {
            var product = orderitem.Product;
            var score = product.price;
            var id = product.id.ToString();
           dic.Add(id,score.ToString());

        }

        req.AddHeader("Content-Type", @"application/json");
        req.AddHeader("Accept", @"application/json");
        req.RequestFormat = DataFormat.Json;
        req.Method = Method.POST;
        req.AddParameter("token" , Atoken);
        req.AddParameter("userid", "123456");
        req.AddParameter("transactionid", "123456");
        req.AddParameter("products",x);
        var response = client.Execute(req);
        string restostr = response.Content.ToString();
        }

和订单类包含订单和订单项的详细信息：

    public Guid orderGuid { get; set; }

      public virtual ICollection<OrderItem> OrderItems
    {
        get { return _orderItems ?? (_orderItems = new List<OrderItem>()); }
        protected set { _orderItems = value; }
    }

和订单项：

    public decimal price{ get; set; }

    public int id{ get; set; }

和错误：状态码

BadRequest  System.Net.HttpStatusCode

Answer 1

似乎您有错字：

您在这里写的产品没有't'

{
    "token": "[access Token]",
    "userid": "[phone number]",
    "transactionid": "a integer number",
    "producs": {  // <<=== producs without t
       "1221": "100",
       "1575": "200"
    }
}

您在这里用't'书写产品

req.AddHeader("Content-Type", @"application/json");
req.AddHeader("Accept", @"application/json");
req.RequestFormat = DataFormat.Json;
req.Method = Method.POST;
req.AddParameter("token" , "token code");
req.AddParameter("userid", "123456");
req.AddParameter("transactionid", "123456");
req.AddParameter("products",x);  // <<<=== products with 't'
var response = client.Execute(req);
string restostr = response.Content.ToString();

我们需要知道什么是“订单”类型来帮助您，但是假设像“ dic”变量那样的2型字典可能以这种方式编写可以帮助您解决问题：

List<Object> me = new List<Object>();
foreach (var x in dic)
{
    object product = new object{x.Key, x.Value};
    me.Add(product);
}

[...]

req.AddParameter("products",me);

我最终找到了解决方案。基于样本请求格式：

   {
   "token": "[access Token]",
   "userid": "[phone number]",
   "transactionid": "a integer number",
   "products": {
   "1221": "100", //product id:product price
   "1575": "200"  //product id:product price
            }

我必须像打击一样将参数添加到jsonbody中：

     var dict = new Dictionary<string, string>();
        foreach (var x in order.OrderItems)
        {
            var price= (x.price);
            var id = x.id.ToString();   
            dict.Add(id,price.ToString("F"));
        }
        req.AddHeader("Content-Type", @"application/json");
        req.AddHeader("Accept", @"application/json");
        req.RequestFormat = DataFormat.Json;
        req.Method = Method.POST;
        req.AddJsonBody(new
        {
            token = Atoken,
            userid = "123456",
            transactionid = "123456",
            productlist=dict
        });
