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：
- C# 使用 HttpClient 访问 RIOT 提供的 API 接口，获取召唤者概况信息；
- 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：
<Window x:Class="LoLGoal.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:materialDesign="http://materialdesigninxaml.net/winfx/xaml/themes"

<Button x:Name="ButtonSignUp" Margin="15 50" Content="搜索" Click="ButtonSignUp_Click"/>
</StackPanel>
</StackPanel>
</Border>
</StackPanel>
</Grid>
</Window>
召唤者概况搜索界面
2.3 召唤者概况信息展示界面
文件【WindowProfile.xaml】，布局代码也不多，清爽：
<Window x:Class="LoLGoal.View.WindowProfile"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:materialDesign="http://materialdesigninxaml.net/winfx/xaml/themes"

</StackPanel>
</StackPanel>
</Grid>
</Window>
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
- 视频一：C# WPF Design UI - #1 - Login，配套源码：LoLGoal。
- 视频二：C# WPF Design UI - #2 (1/2) - REST API Access，配套源码：get_summoner_data。
- 视频三：C# WPF Design UI - #2 (2/2) - REST API Access，配套源码：get_summoner_data。
- 视频四：C# WPF Design UI - #3 - Profile，配套源码：summoner_profile。
- 视频五：C# WPF Design UI - #4 (1/2) - Get Data From RIOT API，配套源码：get_profile_data。
- 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。
