我正在尝试在AngularJS中调用ProcessCriteria方法，但出于某种原因，我不断收到错误消息：
VM18010：1 POST http://example.com/api/TalentPool/ProcessCriteria 404 （未找到）
以下是我的来电代码：
var param = { 'Item': item.Key, 'SolrLabel': SolrLabel };
$http({
method: 'POST',
url: '/api/TalentPool/ProcessCriteria',
data: param
//headers: {
// 'Content-Type': 'application/x-www-form-urlencoded'
//}
}).then(function (response) {
// success
console.log('Facet Data Posted');
return response;
},
function (response) { // optional
// failed
console.log('facet post error occured!');
});
我的服务器端方法：
[System.Web.Http.HttpPost]
public IHttpActionResult ProcessCriteria(string Item, string SolrLabel)
{
var itm = Item;
var solr = SolrLabel;
return Ok();
}
有什么建议吗？

ASP.net无法与Route Table中的请求匹配，因为您的操作中有2个参数，路由器无法理解。
它期望一个数据对象，你的参数会变形。
首先，制作一个类似的模型：
public class Criteria
{
public string Item { get; set; }
public string SolrLabel { get; set; }
}
然后改变你的行动：
[System.Web.Http.HttpPost]
public IHttpActionResult ProcessCriteria(Criteria criteria)
{
var itm = criteria.Item;
var solr = criteria.SolrLabel;
return Ok();
}
并使用JSON.stringify更新您的javaScript部分：
var param = { 'Item': item.Key, 'SolrLabel': SolrLabel };
$http({
method: 'POST',
url: '/api/TalentPool/ProcessCriteria',
data: JSON.stringify(param)
//headers: {
// 'Content-Type': 'application/x-www-form-urlencoded'
//}
}).then(function (response) {
// success
console.log('Facet Data Posted');
return response;
},
function (response) { // optional
// failed
console.log('facet post error occured!');
});

你可以按照上面的答案创建一个类，你可以像http这样在
中传递数据 var obj = {
url: url,
async: true,
method: 'POST',
headers: {
"content-type": "application/json; charset=utf-8",
}
};
if (typeof data != 'undefined' || typeof data != null) {
obj.data = data;
}
$http(obj).then(function(response){
},function(error){
});
