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：

&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;

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】

&lt;Application x:Class=&#34;LoLGoal.App&#34;             xmlns=&#34;http://schemas.microsoft.com/winfx/2006/xaml/presentation&#34;             xmlns:x=&#34;http://schemas.microsoft.com/winfx/2006/xaml&#34;             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：

&lt;Window x:Class=&#34;LoLGoal.MainWindow&#34;        xmlns=&#34;http://schemas.microsoft.com/winfx/2006/xaml/presentation&#34;        xmlns:materialDesign=&#34;http://materialdesigninxaml.net/winfx/xaml/themes&#34;        xmlns:d=&#34;http://schemas.microsoft.com/expression/blend/2008&#34;        xmlns:x=&#34;http://schemas.microsoft.com/winfx/2006/xaml&#34;        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;地区&#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;召唤者&#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;搜索&#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：

&lt;Window x:Class=&#34;LoLGoal.View.WindowProfile&#34;        xmlns=&#34;http://schemas.microsoft.com/winfx/2006/xaml/presentation&#34;        xmlns:materialDesign=&#34;http://materialdesigninxaml.net/winfx/xaml/themes&#34;        xmlns:d=&#34;http://schemas.microsoft.com/expression/blend/2008&#34;        xmlns:x=&#34;http://schemas.microsoft.com/winfx/2006/xaml&#34;        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; ResizeMode=&#34;NoResize&#34;         WindowStyle=&#34;None&#34; Background=&#34;#FF410A66&#34;&gt;    &lt;Grid&gt;        &lt;Border Background=&#34;White&#34; Margin=&#34;20 100 20 20&#34; CornerRadius=&#34;15&#34;&gt;            &lt;StackPanel VerticalAlignment=&#34;Top&#34; HorizontalAlignment=&#34;Stretch&#34;&gt;                &lt;Border Width=&#34;100&#34; Height=&#34;100&#34; Margin=&#34;20 20 0 10&#34; BorderBrush=&#34;Gray&#34; HorizontalAlignment=&#34;Left&#34; BorderThickness=&#34;1&#34; CornerRadius=&#34;15&#34;&gt;                    &lt;Border.Background&gt;                        &lt;ImageBrush ImageSource=&#34;{Binding Path=Icon}&#34;/&gt;                    &lt;/Border.Background&gt;                &lt;/Border&gt;                &lt;TextBlock Margin=&#34;20 15&#34; FontSize=&#34;30&#34; Text=&#34;{Binding Path=SummonerName}&#34; Foreground=&#34;DarkGray&#34;/&gt;                &lt;StackPanel Orientation=&#34;Horizontal&#34; Margin=&#34;20 0&#34;&gt;                    &lt;StackPanel Margin=&#34;5&#34;&gt;                        &lt;TextBlock Text=&#34;胜&#34; FontSize=&#34;15&#34; FontWeight=&#34;Bold&#34; Foreground=&#34;Green&#34;/&gt;                        &lt;TextBlock Text=&#34;{Binding Path=Wins}&#34; FontSize=&#34;18&#34; Foreground=&#34;Gray&#34; HorizontalAlignment=&#34;Center&#34;/&gt;                    &lt;/StackPanel&gt;                    &lt;StackPanel Margin=&#34;5&#34;&gt;                        &lt;TextBlock Text=&#34;输&#34; FontSize=&#34;15&#34; FontWeight=&#34;Bold&#34; Foreground=&#34;DarkRed&#34;/&gt;                        &lt;TextBlock Text=&#34;{Binding Path=Losses}&#34; FontSize=&#34;18&#34; Foreground=&#34;Gray&#34; HorizontalAlignment=&#34;Center&#34;/&gt;                    &lt;/StackPanel&gt;                &lt;/StackPanel&gt;                &lt;StackPanel Margin=&#34;30 20&#34;&gt;                    &lt;TextBlock Text=&#34;水平&#34; FontSize=&#34;15&#34; Foreground=&#34;LightGray&#34;/&gt;                    &lt;TextBlock Text=&#34;{Binding Path=Level}&#34; HorizontalAlignment=&#34;Center&#34; FontSize=&#34;80&#34; Foreground=&#34;Gray&#34;/&gt;                &lt;/StackPanel&gt;                &lt;Grid Margin=&#34;20 10&#34;&gt;                    &lt;Button x:Name=&#34;ButtonSearch&#34; HorizontalAlignment=&#34;Left&#34; Style=&#34;{StaticResource MaterialDesignFlatButton}&#34; Width=&#34;100&#34; Click=&#34;ButtonSearch_Click&#34;&gt;                        &lt;materialDesign:PackIcon Kind=&#34;Search&#34; Width=&#34;24&#34; Height=&#34;24&#34;/&gt;                    &lt;/Button&gt;                    &lt;Button HorizontalAlignment=&#34;Right&#34; Width=&#34;100&#34; Content=&#34;登录&#34;/&gt;                &lt;/Grid&gt;            &lt;/StackPanel&gt;        &lt;/Border&gt;        &lt;StackPanel HorizontalAlignment=&#34;Right&#34; Margin=&#34;30 10&#34;&gt;            &lt;Image Source=&#34;{Binding Path=Emblem}&#34; Width=&#34;200&#34; Height=&#34;200&#34;&gt;                &lt;Image.Effect&gt;                    &lt;DropShadowEffect BlurRadius=&#34;40&#34; ShadowDepth=&#34;1&#34;/&gt;                &lt;/Image.Effect&gt;            &lt;/Image&gt;            &lt;StackPanel Orientation=&#34;Horizontal&#34; HorizontalAlignment=&#34;Center&#34; Margin=&#34;5&#34;&gt;                &lt;TextBlock FontSize=&#34;18&#34; Foreground=&#34;Gray&#34; Text=&#34;{Binding Path=Tier}&#34; Margin=&#34;5&#34; VerticalAlignment=&#34;Center&#34;/&gt;                &lt;TextBlock FontSize=&#34;20&#34; Foreground=&#34;Gray&#34; Text=&#34;{Binding Path=Rank}&#34; Margin=&#34;5&#34;/&gt;            &lt;/StackPanel&gt;        &lt;/StackPanel&gt;    &lt;/Grid&gt;&lt;/Window&gt;

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(&#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 其他代码

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：

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。
