从Javascript传递KeyValuePair或IDictionary的清单对Web API控制器 [英] Passing List of KeyValuePair or IDictionary to Web Api Controller from Javascript

问题描述

我有一个Web API控制器，​​而我想后两个参数。一个是平坦INT的ID，而另一个是一个IDictionary或类似等效

I have a web api controller to which I would like to post two parameters. One is a flat int ID, and the other is an IDictionary or similar equivalent.

[HttpPost]
public void DoStuff(int id, [FromBody]IDictionary<int, int> things)
{
}

var things = new Array();
things.push({ 1: 10 }); // tried things.push({ Key: 1, Value: 10 })
things.push({ 2: 11 });
$.ajax({
    url: '/api/DoStuff?id=' + id,
    data: '=' + JSON.stringify(things), // tried what seems like 100 different things here
    type: 'POST',
    dataType: 'json'
});

不管是什么我尝试在数据参数（数据：事情，数据：'='+事情 ），字典不通过走到API控制器。它是null或有一个假的条目（{0，0}）。

No matter what I try in the data param (data: things, data: '=' + things), the Dictionary does not come through to the api controller. It is either null or has one bogus entry ({0, 0}).

我也试图发送词典在乌里 - 不走

I have also tried to send the Dictionary in the Uri - no go.

我如何发送词典或键值对的API控制器？

How can I send the dictionary or key value pair to the api controller?

推荐答案

您不需要一个数组 - 你需要一个简单的JS对象（映射到一个字典）。这code应该工作：

You don't need an array - you need a simple JS object (which maps to a dictionary). This code should work:

var things = {};
things['1'] = 10;
things['2'] = 11;
$.ajax({
    url: '/api/DoStuff?id=' + id,
    data: JSON.stringify(things),
    contentType: 'application/json'
    type: 'POST',
    dataType: 'json'
});
