C# WPF从RIOT API获取数据(RIOT代表作品《英雄联盟》)

1. 本文背景

RIOT(拳头)是一家美国网游开发商，成立于2006年，代表作品《英雄联盟》。

本文重点要讲解两个知识点：

1. C# 使用 HttpClient 访问 RIOT 提供的 API 接口，获取召唤者概况信息；
2. C# WPF界面展示召唤者信息搜索、概况信息两个界面。

2. 代码实现

站长使用 .Net CORE 3.1 创建名为 “LoLGoal” 的WPF解决方案，并添加3个Nuget包，配置如下：

<?xml version="1.0" encoding="utf-8"?>
<packages>
  <package id="MaterialDesignColors" version="1.1.1" targetFramework="net45" />
  <package id="MaterialDesignThemes" version="2.5.0.1205" targetFramework="net45" />
  <package id="Newtonsoft.Json" version="12.0.1" targetFramework="net45" />
</packages>

界面使用的MD控件，本站曾有介绍：介绍 。

本文只简单说明部分代码，整体解决方案目录结构如下，源码文末会给出：

2.1 引入MD控件样式

文件【App.xaml】

<Application x:Class="LoLGoal.App"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             StartupUri="View/MainWindow.xaml">
    <Application.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Light.xaml" />
                <ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Defaults.xaml" />
                <ResourceDictionary Source="pack://application:,,,/MaterialDesignColors;component/Themes/Recommended/Primary/MaterialDesignColor.Purple.xaml" />
                <ResourceDictionary Source="pack://application:,,,/MaterialDesignColors;component/Themes/Recommended/Accent/MaterialDesignColor.Blue.xaml" />
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Application.Resources>
</Application>

2.2 召唤者概况搜索界面

文件【MainWindow.xaml】代码，界面布局简单，给人的感觉整体简洁大方：

概况信息展示界面

2.4 简单的API接口调用封装

直接上代码看，Key.txt是存储的RIOT开发者Key：

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Net.Http;
using System.Text;
using System.Threading.Tasks;

namespace LoLGoal.API
{
    public class Api
    {
        private string Key { get; set; }
        private string Region { get; set; }

        public Api(string region)
        {
            Region = region;
            Key = GetKey("API/Key.txt");
        }

        protected HttpResponseMessage GET(string URL)
        {
            using (HttpClient client = new HttpClient())
            {
                var result = client.GetAsync(URL);
                result.Wait();

                return result.Result;
            }
        }

        protected string GetURI(string path)
        {
            return "https://" + Region + ".api.riotgames.com/lol/" + path + "?api_key=" + Key;
        }

        public string GetKey(string path)
        {
            StreamReader sr = new StreamReader(path);
            return sr.ReadToEnd();
        }
    }
}

2.5 其他代码

查看源码：get_profile_data

2.6 以下是站长方便演示、截图，修改的部分文件

可参考源码对比：

文件【API/League_V4.cs】

using LoLGoal.Model;
using System;
using System.Collections.Generic;

namespace LoLGoal.API
{
    public class League_V4 : Api
    {
        public League_V4(string region) : base(region)
        {
        }

        public List<PositionDTO> GetPositions(string summonerId)
        {
            //1、这是正常的API访问
            //string path = "league/v4/positions/by-summoner/" + summonerId;

            //var response = GET(GetURI(path));
            //string content = response.Content.ReadAsStringAsync().Result;

            //if (response.StatusCode == System.Net.HttpStatusCode.OK)
            //{
            //    return JsonConvert.DeserializeObject<List<PositionDTO>>(content);
            //}
            //else
            //{
            //    return null;
            //}

            //2、这是模拟数据，正常访问LOL服务器，需要注册Key
            string[] tiers = { "Bronze", "Challenger", "Diamond", "Gold", "Grandmaster", "Iron", "Master", "Platinum", "Silver" };
            var rd = new Random(DateTime.Now.Millisecond);
            var lst = new List<PositionDTO>();
            for (int i = 0; i < rd.Next(5, 20); i++)
            {
                lst.Add(new PositionDTO
                {
                    Tier = tiers[rd.Next(0, tiers.Length)],
                    Rank = "IV",
                    Wins = rd.Next(2, 100),
                    Losses = rd.Next(2, 100),
                    QueueType = "RANKED_SOLO_5x5"
                });
            }
            return lst;
        }
    }
}

文件【API/Summoner_V4.cs】

using LoLGoal.Model;
using System;

namespace LoLGoal.API
{
    public class Summoner_V4 : Api
    {
        public Summoner_V4(string region) : base(region)
        {
        }

        public SummonerDTO GetSummonerByName(string SummonerName)
        {
            //1、这是正常的API访问
            //string path = "summoner/v4/summoners/by-name/" + SummonerName;

            //var response = GET(GetURI(path));
            //string content = response.Content.ReadAsStringAsync().Result;

            //if(response.StatusCode == System.Net.HttpStatusCode.OK)
            //{
            //    return JsonConvert.DeserializeObject<SummonerDTO>(content);
            //}
            //else
            //{
            //    return null;
            //}

            //2、这是模拟数据，正常访问LOL服务器，需要注册Key
            return new SummonerDTO
            {
                ProfileIconId = DateTime.Now.Second,
                Name = SummonerName,
                SummonerLevel = new Random(DateTime.Now.Millisecond).Next(50, 200),
                Id = DateTime.Now.Second.ToString()
            };
        }
    }
}

3.参考

1. 视频一：C# WPF Design UI – #1 – Login，配套源码：LoLGoal。
2. 视频二：C# WPF Design UI – #2 (1/2) – REST API Access，配套源码：get_summoner_data。
3. 视频三：C# WPF Design UI – #2 (2/2) – REST API Access，配套源码：get_summoner_data。
4. 视频四：C# WPF Design UI – #3 – Profile，配套源码：summoner_profile。
5. 视频五：C# WPF Design UI – #4 (1/2) – Get Data From RIOT API，配套源码：get_profile_data。
6. 视频六：C# WPF Design UI – #4 (2/2)- Get Data From RIOT API，配套源码：get_profile_data。

最终源码：本文代码几乎和源码一致（第五和第六个视频配套Github源码 【get_profile_data】），站长未注册RIOT开发者Key，所以代码中采用模拟返回数据的方式，只展示了界面效果，并将部分英文改为中文，便于向大家展示此工程。
