如何正确传递和接收json对象？(How to properly pass and receive a json object?)

从客户端，我想将一组json节点： [{key, value},{key, value}]传递给WebAPI端点。 我的api端点param类型应该是什么？ 列表<>（）或其他什么？

这将是使用C＃。

我需要遍历集合中传递的每个端点。

From the client, I would like to pass a collection of json nodes: [{key, value},{key, value}] to a WebAPI endpoint. what should my api endpoint param type be? a List<>() or something else?

This would be using C#.

I need to iterate over each endpoint that is passed in the collection.

通常，最好创建一个将JSON反序列化的模型。 如果您的JSON采用格式，请回答您的问题

[{key1: value1},{key2: value2}]

你可以用一个

List<Dictionary<string,object>>()

如果您确定您的值始终是字符串值，那么您可以这样做

List<Dictionary<string,string>>()

由于JSON值可以是字符串（用引号括起来），整数（没有引号）或null。

所以你的Web API控制器可能是这样的：

[HttpPost] public IHttpActionResult ReceiveJSON([FromBody]List<Dictionary<string,string>> in_json) { // And then one way to iterate over each 'json node' passed foreach(var dict in in_json) { // Do something with dictionary object } return Ok(in_sjon); }

您将使用什么版本的ASP.Net Web API？

In general, it is good practice to create a model that your JSON will be deserialized into. To answer your question though if your JSON was in the format

[{key1: value1},{key2: value2}]

you would be able to use a

List<Dictionary<string,object>>()

If you were sure that your values were always string values you could do

List<Dictionary<string,string>>()

As JSON values can be strings (wrapped in quotes), integers (no quotes) or null.

So your Web API controller could be something like this:

[HttpPost] public IHttpActionResult ReceiveJSON([FromBody]List<Dictionary<string,string>> in_json) { // And then one way to iterate over each 'json node' passed foreach(var dict in in_json) { // Do something with dictionary object } return Ok(in_sjon); }

What version of ASP.Net Web API will you be using?
