Question

我正在尝试使用mongoDB创建一个web api。

这是我的model

public class Entity
    {
        [BsonId]
        public int Id { get; set; }
        public string Name { get; set; }

        public string Gender { get; set; }
    }

这个Post方法

public void Post(Entity entity)
        {
            var client = new MongoClient("mongodb://localhost:27017");
            var server = client.GetServer();
            var db = server.GetDatabase("Test");
            var collection = db.GetCollection<Entity>("Entities");
            collection.Save(entity);
        }

当我尝试使用单个数据时，它可以正常工作。

jQuery.ajax({
            type: "POST",
            datatype: "json",
            url: "http://localhost:10746/api/values",
            data: { "ID": 1, "Gender": "Male", "Name": "John" },
            success: function (data) {
                alert(data);
            }
        });

但是当我尝试这个时它没有用。

var entities = [
                    { "ID": 1, "Gender": "Male", "Name": "John" },
                    { "ID": 2, "Gender": "Male", "Name": "Mark" },
                    { "ID": 3, "Gender": "Male", "Name": "Tim" },
                    { "ID": 4, "Gender": "Male", "Name": "Tom" },
                    { "ID": 5, "Gender": "Female", "Name": "Julia" },
                    { "ID": 6, "Gender": "Female", "Name": "Joss" }
                ]


        jQuery.ajax({
            type: "POST",
            datatype: "json",
            url: "http://localhost:10746/api/values",
            data: entities,
            success: function (data) {
                alert(data);
            }
        });

我只想知道在调用Ajax时如何传递数组。

编辑：发布Javascript代码。

这是因为您的Post方法接受单个Entity对象而不是Entity实例的列表或数组。您可以按如下方式更改方法。

public void Post(List<Entity> entities)
{
    var client = new MongoClient("mongodb://localhost:27017");
    var server = client.GetServer();
    var db = server.GetDatabase("Test");
    foreach(var entity in entities)
    {
        var collection = db.GetCollection<Entity>("Entities");
        collection.Save(entity);
    }
}

Javascript代码：

var entities = [
                    { "ID": 1, "Gender": "Male", "Name": "John" },
                    { "ID": 2, "Gender": "Male", "Name": "Mark" },
                    { "ID": 3, "Gender": "Male", "Name": "Tim" },
                    { "ID": 4, "Gender": "Male", "Name": "Tom" },
                    { "ID": 5, "Gender": "Female", "Name": "Julia" },
                    { "ID": 6, "Gender": "Female", "Name": "Joss" }
                ];

var postString = JSON.stringify(entities);


        jQuery.ajax({
            type: "POST",
            datatype: "json",
            contentType: 'application/json',
            url: "http://localhost:10746/api/values",
            data: postString,
            success: function (data) {
                alert(data);
            }
        });

Ajax POST调用不起作用
