Passing an JSON array to MVC Web API via GET
提问by Remy
I know there are tons of answers for this topic, but couldn't find the solution to my issue. I have an ASP.NET MVC Web API that looks like this:
我知道这个话题有很多答案，但找不到我的问题的解决方案。我有一个 ASP.NET MVC Web API，如下所示：
[HttpGet]
public IList<Country> GetCountryList(List<long> idList)
And I've tried calling it like this:
我试过这样称呼它：
$.ajax({
dataType: "json",
data: JSON.stringify({idList: listOfIds}),
type: "GET",
url: "api/v1/util/CountryList",
success: function (result) {
alert(result);
}
});
The URL then looks like this:
该 URL 如下所示：
https://localhost/supertext/api/v1/util/CountryList?{%22idList%22:[46,14,62,83,120]}
Alternative:
选择：
$.ajax({
dataType: "json",
data: {
idList: JSON.stringify(listOfIds),
}
type: "GET",
url: "api/v1/util/CountryList",
success: function (result) {
alert(result);
}
});
URL:
网址：
https://localhost/supertext/api/v1/util/CountryList?idList=%5B46%2C14%2C62%2C83%2C120%5D
Both methods don't work.
两种方法都行不通。
Do I really have to send and receive it as a string or use POST?
我真的必须以字符串形式发送和接收它或使用 POST 吗？

No, don't try to be sending JSON in a GET request. Use JSON with other verbs which have body, such as POST and PUT.
不，不要尝试在 GET 请求中发送 JSON。将 JSON 与其他具有正文的动词一起使用，例如 POST 和 PUT。
Do it the standard way, by decorating your action parameter with the [FromUri]attribute:
通过使用[FromUri]属性装饰您的操作参数，以标准方式执行此操作：
public IList<Country> GetCountryList([FromUri] List<long> idList)
{
...
}
and then just trigger the AJAX request:
然后触发 AJAX 请求：
$.ajax({
url: 'api/v1/util/CountryList',
type: 'GET',
data: { idList: [1, 2, 3] },
traditional: true,
success: function (result) {
console.log(JSON.stringify(result));
}
});

[HttpGet]
