AngularJS使用$resource将数据发布到WebAPI

Question

好吧，我相信我已经接近完成这项工作了，但似乎无法识别我的WebAPI控制器，除非我在URI中传递参数。

我有。。。Angular像这样使用$resource

var savePromise = myService.common.SaveData.save({},{ ID: saveObj.ID, Year: saveObj.Year, typeID: saveObj.TypeID, ObjectList: JSON.stringify(saveCollection) }).$promise;

收集URL并通过调用WebAPI传递此数据的服务

SaveData:$resource(myURL，｛｝(

WebAPI控制器

public class ObjectsSaveController : ApiController
{
[System.Web.Http.HttpPost]
public HttpResponseMessage POST([FromBody] int ID, int Year, 
int typeID, string ObjectList) {

如果我不在查询字符串中传递值，那么就找不到ApiController。

感谢您的帮助！！

好的，我已经成功地使用POST在AngularJS中发送数据。。。我是怎么做到的…

获取我传递的参数，并将它们放在一个javascript对象中

var objData = {
Var1: Var1Value,
Var2: Var2Value,
Var3: Var3Value,
Var4: Var4Value 
}

在"保存"请求中传递该对象

var savePromise = myService.common.SavePostData.save({}, objData).$promise;

我在一个服务中拥有资源，该服务构建调用并执行(函数(角度，未定义({"严格使用"；

angular.module('mynamespace.myservice', [
// Angular
'ngResource'
])
.factory('myservice', ['$resource', function ($resource) {
return {
common: {
SavePostData: $resource(myURL, {})
}
};
}]);

}(有角度的((；

好吧！！现在是最重要的部分在WebApi方面，您必须创建POST映射到的数据模型。。。~注意变量的"case"必须匹配！

using System.Collections.ObjectModel;
namespace myNamespace {
public class DataModelThatMatchesRequest {
public int Var1 {
get;
set;
}
public int Var2 {
get;
set;
}
public int Var3 {
get;
set;
}
public Var4  {
get;
set;
}
}

}

现在创建一个使用您的数据模型的ApiController~注意你必须有装饰器"[HttpPost]"和操作装饰器"[FromBody]">

public class SaveObjectController : ApiController {
[HttpPost]        
public Objects POST([FromBody] DataModelThatMatchesRequest saveRequest) 
{
Do some stuff with "saveRequest"
}

我希望这对你有帮助！！
