Question

我从AngularJS调用C＃操作方法（Mvc.Controller），并且该操作中的param为null。为什么呢？

以下是Angular电话：

return $http.get(
                "AdvancedSearch/SearchUsers",
                {
                    params: {
                        search: {
                            SearchTerms: searchTerms,
                            Markets: markets,
                            Roles: roles,
                            Capabilities: capabilities,
                            Groups: groups,
                            Industries: experience,
                            Skills: skills,
                            Technologies: technologies,
                            Certifications: certification
                        }
                    }
                }
            );

这是C＃视图模型：

public class SearchViewModel
{
    public string SearchTerms { get; set; }
    public List<string> Markets { get; set; }
    public List<int> Roles { get; set; }
    public List<string> Capabilities { get; set; }
    public List<string> Groups { get; set; }
    public List<int> Industries { get; set; }
    public List<int> Skills { get; set; }
    public List<int> Technologies { get; set; }
    public List<string> Certifications { get; set; }
}

这里是行动方法签名：

[HttpGet]
public JsonResult SearchUsers(SearchViewModel search) // <- this is null

这是请求网址，已解码：

https://localhost:44300/AdvancedSearch/SearchUsers?search={"SearchTerms":"","Markets":["Boise"],"Roles":[],"Capabilities":[],"Groups":[],"Industries":[],"Skills":[],"Technologies":[],"Certifications":[]}

在我使用单独的参数转换为使用单一视图模型之前，调用工作正常。

更新：尝试传递为单个字符串参数。

以下是Angular电话：

return $http.get(
                "AdvancedSearch/SearchUsers",
                {
                    params: JSON.stringify({
                        jsonSearchData: {
                            SearchTerms: searchTerms,
                            Markets: markets,
                            Roles: roles,
                            Capabilities: capabilities,
                            Groups: groups,
                            Industries: experience,
                            Skills: skills,
                            Technologies: technologies,
                            Certifications: certifications
                        }
                    })
                }
            );

这是新的C＃方法签名：

public JsonResult SearchUsers(string jsonSearchData) // still coming over null
