unity通过WebAPI调用MongoDB

1.unity模块-调用WebAPI：

using UnityEngine;
using System.Collections;
using System.IO;
using System.Collections.Generic;
using System.Linq;
using System.Net; 
 
public class LoadMongoDB : MonoBehaviour
{ 
    public string url;
    void Start()
    {    
         if (string.IsNullOrEmpty(url))
         {
              url = "http://localhost:23544/ActionApi/UserInfo/CreatMongoDB?MongoClient_DB_Name=mongodb://ip(mongodb库的连接ip和端口),MyMongoDB,BsonDocumentName";
         }
    }
    void Update()
    { 
        if (Input.GetKeyDown(KeyCode.P))
        {  
            string str = HttpPost(url, "");
            Debug.Log(str);
        }
    }
    public static string HttpPost(string url, string body)
    {  
        HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
        request.Method = "POST"; 

        byte[] buffer = System.Text.Encoding.UTF8.GetBytes(body);
        request.ContentLength = buffer.Length;
        request.GetRequestStream().Write(buffer, 0, buffer.Length);
        HttpWebResponse response = (HttpWebResponse)request.GetResponse();
        using (StreamReader reader = new StreamReader(response.GetResponseStream(), System.Text.Encoding.UTF8))
        {
            return reader.ReadToEnd();
        }
    }
}    

2.WebAPI模块-Web API 路由定义：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net.Http;
using System.Web.Http;
using Microsoft.Owin.Security.OAuth;
using Newtonsoft.Json.Serialization;

namespace WebAPI_Mongo
{
    public static class WebApiConfig
    {
        public static void Register(HttpConfiguration config)
        {
            // Web API 配置和服务
            // 将 Web API 配置为仅使用不记名令牌身份验证。
            config.SuppressDefaultHostAuthentication();
            config.Filters.Add(new HostAuthenticationFilter(OAuthDefaults.AuthenticationType));

            // Web API 路由
            config.MapHttpAttributeRoutes();

            //自定义路由：匹配到action
            config.Routes.MapHttpRoute(
                name: "ActionApi",
                routeTemplate: "actionapi/{controller}/{action}/{id}",
                defaults: new { id = RouteParameter.Optional }
            );
        }
    }
}

3.WebAPI模块-调用MongoDB：

using System.Linq;
using System.Net.Http;
using System.Text.RegularExpressions;
using System.Web.Http;
using MongoDB.Bson;
using MongoDB.Driver; 

namespace WebAPI_Mongo.Controllers
{
    public class UserInfoController : ApiController
    {  
        private ApiTools tool = new ApiTools(); 

        MongoClient client;
        IMongoDatabase database;
        IMongoCollection<BsonDocument> collection; 
        [HttpPost]
        public HttpResponseMessage CreatMongoDB(string MongoClient_DB_Name)
        {
            //Connection_MongoDB();
            //增加
            client = new MongoClient(MongoClient_DB_Name.Split(',')[0]);
            database = client.GetDatabase(MongoClient_DB_Name.Split(',')[1]);
            collection = database.GetCollection<BsonDocument>(MongoClient_DB_Name.Split(',')[2]);

            BsonDocument ls_BsonDocument = new BsonDocument { { "Name", "_萧朗" } };
            collection.InsertOne(ls_BsonDocument); 

            return tool.MsgFormat(ResponseCode.成功, "已建立" + MongoClient_DB_Name.Split(',')[2], "true");
        } 
    }
    public class ApiTools
    {
        private string msgModel = "{{"code":{0},"message":"{1}","result":{2}}}"; 

        public HttpResponseMessage MsgFormat(ResponseCode code, string explanation, string result)
        {
            string r = @"^(-|+)?d+(.d+)?$";
            string json = string.Empty;
            if (Regex.IsMatch(result, r) || result.ToLower() == "true" || result.ToLower() == "false" || result == "[]" || result.Contains('{'))
            {
                json = string.Format(msgModel, (int)code, explanation, result);
            }
            else
            {
                if (result.Contains('"'))
                {
                    json = string.Format(msgModel, (int)code, explanation, result);
                }
                else
                {
                    json = string.Format(msgModel, (int)code, explanation, """ + result + """);
                }
            }
            return new HttpResponseMessage { Content = new StringContent(json, System.Text.Encoding.UTF8, "application/json") };
        }
    }
    public enum ResponseCode
    {
        失败 = 00000,
        成功 = 10200,
    }
}
