C# WPF從RIOT API獲取資料(RIOT代表作品《英雄聯盟》)

閱讀導航

本文背景程式碼實現本文參考1. 本文背景

RIOT(拳頭)是一家美國網遊開發商，成立於2006年，代表作品《英雄聯盟》。

本文重點要講解兩個知識點：

2. 程式碼實現

站長使用 .Net CORE 3.1 建立名為 “LoLGoal” 的WPF解決方案，並新增3個Nuget包，配置如下：

&lt;?xml version=&#34;1.0&#34; encoding=&#34;utf-8&#34;?&gt;&lt;packages&gt;  &lt;package id=&#34;MaterialDesignColors&#34; version=&#34;1.1.1&#34; targetFramework=&#34;net45&#34; /&gt;  &lt;package id=&#34;MaterialDesignThemes&#34; version=&#34;2.5.0.1205&#34; targetFramework=&#34;net45&#34; /&gt;  &lt;package id=&#34;Newtonsoft.Json&#34; version=&#34;12.0.1&#34; targetFramework=&#34;net45&#34; /&gt;&lt;/packages&gt;

介面使用的MD控制元件，本站曾有介紹：介紹。

本文只簡單說明部分程式碼，整體解決方案目錄結構如下，原始碼文末會給出：

2.1 引入MD控制元件樣式

檔案【App.xaml】

&lt;Application x:Class=&#34;LoLGoal.App&#34;             xmlns=&#34;/file/2020/01/13/20200113185401_24316.jpg.aspx             xmlns:x=&#34;/file/2020/01/13/20200113185401_24317.jpg.aspx             StartupUri=&#34;View/MainWindow.xaml&#34;&gt;    &lt;Application.Resources&gt;        &lt;ResourceDictionary&gt;            &lt;ResourceDictionary.MergedDictionaries&gt;                &lt;ResourceDictionary Source=&#34;pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Light.xaml&#34; /&gt;                &lt;ResourceDictionary Source=&#34;pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Defaults.xaml&#34; /&gt;                &lt;ResourceDictionary Source=&#34;pack://application:,,,/MaterialDesignColors;component/Themes/Recommended/Primary/MaterialDesignColor.Purple.xaml&#34; /&gt;                &lt;ResourceDictionary Source=&#34;pack://application:,,,/MaterialDesignColors;component/Themes/Recommended/Accent/MaterialDesignColor.Blue.xaml&#34; /&gt;            &lt;/ResourceDictionary.MergedDictionaries&gt;        &lt;/ResourceDictionary&gt;    &lt;/Application.Resources&gt;&lt;/Application&gt;

2.2 召喚者概況搜尋介面

檔案【MainWindow.xaml】程式碼，介面佈局簡單，給人的感覺整體簡潔大方：

&lt;Window x:Class=&#34;LoLGoal.MainWindow&#34;        xmlns=&#34;/file/2020/01/13/20200113185401_24316.jpg.aspx        xmlns:materialDesign=&#34;/file/2020/01/13/20200113185402_24318.jpg        xmlns:d=&#34;/file/2020/01/13/20200113185403_24319.jpg.aspx        xmlns:x=&#34;/file/2020/01/13/20200113185401_24317.jpg.aspx        xmlns:mc=&#34;http://schemas.openxmlformats.org/markup-compatibility/2006&#34;        mc:Ignorable=&#34;d&#34; Height=&#34;600&#34; Width=&#34;400&#34; WindowStartupLocation=&#34;CenterScreen&#34;         MouseLeftButtonDown=&#34;Window_MouseLeftButtonDown&#34;        ResizeMode=&#34;NoResize&#34; WindowStyle=&#34;None&#34; Background=&#34;#FF410A66&#34;&gt;    &lt;Grid&gt;        &lt;StackPanel Margin=&#34;50&#34;&gt;            &lt;Image Source=&#34;/Assets/logo2.png&#34; Width=&#34;96&#34; Height=&#34;96&#34;/&gt;            &lt;Border Background=&#34;White&#34; Margin=&#34;10 20&#34; CornerRadius=&#34;5&#34;&gt;                &lt;StackPanel Margin=&#34;25&#34;&gt;                    &lt;ComboBox Margin=&#34;15&#34; Style=&#34;{StaticResource MaterialDesignFloatingHintComboBox}&#34; materialDesign:HintAssist.Hint=&#34;地區&#34; Text=&#34;{Binding Region}&#34;&gt;                        &lt;ComboBoxItem Content=&#34;RU&#34;/&gt;                        &lt;ComboBoxItem Content=&#34;KR&#34;/&gt;                        &lt;ComboBoxItem Content=&#34;BR1&#34;/&gt;                        &lt;ComboBoxItem Content=&#34;OC1&#34;/&gt;                        &lt;ComboBoxItem Content=&#34;JP1&#34;/&gt;                        &lt;ComboBoxItem Content=&#34;NA1&#34;/&gt;                        &lt;ComboBoxItem Content=&#34;EUN1&#34;/&gt;                        &lt;ComboBoxItem Content=&#34;EUW1&#34;/&gt;                        &lt;ComboBoxItem Content=&#34;TR1&#34;/&gt;                        &lt;ComboBoxItem Content=&#34;LA1&#34;/&gt;                        &lt;ComboBoxItem Content=&#34;LA2&#34;/&gt;                    &lt;/ComboBox&gt;                    &lt;TextBox Text=&#34;{Binding SummonerName}&#34; Margin=&#34;15&#34; Style=&#34;{StaticResource MaterialDesignFloatingHintTextBox}&#34; materialDesign:HintAssist.Hint=&#34;召喚者&#34;/&gt;                    &lt;StackPanel Orientation=&#34;Horizontal&#34; HorizontalAlignment=&#34;Center&#34;&gt;                        &lt;Button Margin=&#34;15 50&#34; Content=&#34;取消&#34;/&gt;                        &lt;Button x:Name=&#34;ButtonSignUp&#34; Margin=&#34;15 50&#34; Content=&#34;搜尋&#34; Click=&#34;ButtonSignUp_Click&#34;/&gt;                    &lt;/StackPanel&gt;                &lt;/StackPanel&gt;            &lt;/Border&gt;        &lt;/StackPanel&gt;    &lt;/Grid&gt;&lt;/Window&gt;

召喚者概況搜尋介面

2.3 召喚者概況資訊展示介面

檔案【WindowProfile.xaml】，佈局程式碼也不多，清爽：

概況資訊展示介面

2.4 簡單的API介面呼叫封裝

直接上程式碼看，Key.txt是儲存的RIOT開發者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(&#34;API/Key.txt&#34;);        }        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 &#34;https://&#34; + Region + &#34;.api.riotgames.com/lol/&#34; + path + &#34;?api_key=&#34; + Key;        }        public string GetKey(string path)        {            StreamReader sr = new StreamReader(path);            return sr.ReadToEnd();        }    }}

2.5 其他程式碼

檢視原始碼：get_profile_data

2.6 以下是站長方便演示、截圖，修改的部分檔案

可參考原始碼對比：

檔案【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&lt;PositionDTO&gt; GetPositions(string summonerId)        {            //1、這是正常的API訪問            //string path = &#34;league/v4/positions/by-summoner/&#34; + summonerId;            //var response = GET(GetURI(path));            //string content = response.Content.ReadAsStringAsync().Result;            //if (response.StatusCode == System.Net.HttpStatusCode.OK)            //{            //    return JsonConvert.DeserializeObject&lt;List&lt;PositionDTO&gt;&gt;(content);            //}            //else            //{            //    return null;            //}            //2、這是模擬資料，正常訪問LOL伺服器，需要註冊Key            string[] tiers = { &#34;Bronze&#34;, &#34;Challenger&#34;, &#34;Diamond&#34;, &#34;Gold&#34;, &#34;Grandmaster&#34;, &#34;Iron&#34;, &#34;Master&#34;, &#34;Platinum&#34;, &#34;Silver&#34; };            var rd = new Random(DateTime.Now.Millisecond);            var lst = new List&lt;PositionDTO&gt;();            for (int i = 0; i &lt; rd.Next(5, 20); i++)            {                lst.Add(new PositionDTO                {                    Tier = tiers[rd.Next(0, tiers.Length)],                    Rank = &#34;IV&#34;,                    Wins = rd.Next(2, 100),                    Losses = rd.Next(2, 100),                    QueueType = &#34;RANKED_SOLO_5x5&#34;                });            }            return lst;        }    }}

檔案【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、這是正常的API訪問            //string path = &#34;summoner/v4/summoners/by-name/&#34; + SummonerName;            //var response = GET(GetURI(path));            //string content = response.Content.ReadAsStringAsync().Result;            //if(response.StatusCode == System.Net.HttpStatusCode.OK)            //{            //    return JsonConvert.DeserializeObject&lt;SummonerDTO&gt;(content);            //}            //else            //{            //    return null;            //}            //2、這是模擬資料，正常訪問LOL伺服器，需要註冊Key            return new SummonerDTO            {                ProfileIconId = DateTime.Now.Second,                Name = SummonerName,                SummonerLevel = new Random(DateTime.Now.Millisecond).Next(50, 200),                Id = DateTime.Now.Second.ToString()            };        }    }}

3.參考視訊一：C# WPF Design UI - #1 - Login，配套原始碼：LoLGoal。視訊二：C# WPF Design UI - #2 (1/2) - REST API Access，配套原始碼：get_summoner_data。視訊三：C# WPF Design UI - #2 (2/2) - REST API Access，配套原始碼：get_summoner_data。視訊四：C# WPF Design UI - #3 - Profile，配套原始碼：summoner_profile。視訊五：C# WPF Design UI - #4 (1/2) - Get Data From RIOT API，配套原始碼：get_profile_data。視訊六：C# WPF Design UI - #4 (2/2)- Get Data From RIOT API，配套原始碼：get_profile_data。

最終原始碼：本文程式碼幾乎和原始碼一致（第五和第六個視訊配套Github原始碼【get_profile_data】），站長未註冊RIOT開發者Key，所以程式碼中採用模擬返回資料的方式，只展示了介面效果，並將部分英文改為中文，便於向大家展示此工程。
