建立连网请求功能测试 Unity专案

接下来实作连网功能测试

先创建一个测试连线的版本

开啓 Unity Hub使用 Unity 2021.3.7f1 开一个新专案建立 一般 UI 或 GUI 择一即可，测试建议使用GUI较方便

---

- 使用一般 UI

滑鼠右键 "Hierachy" > "UI" > "Canvas" （Create Canvas）滑鼠左键 点Canvas in "Hierachy"> "Inspector" > "Canvas Scaler">
"UI Scale Mode" Change to "Scale With Screen Size">
"Reference Resolution" Set to X"1920" Y"1080"滑鼠左键 点Canvas in "Hierachy"（Select "Canvas"）>
滑鼠右键 "Canvas">"UI">"Legacy">"Text"（Create Text）>"txt_Result"（Name it）滑鼠左键 点Project>Asset>滑鼠右键"Create">"Folder">"Scripts"（Name it）左键双击"Scripts"Folder>滑鼠右键"Create"> C# Script>Type "GetTest"（得到 GetTest.cs）左键双击GetTest.cs打开IDE（Visual Studio）
以下是 GetTest.cs 的代码：

using System.Collections;using UnityEngine;using UnityEngine.Networking;using UnityEngine.UI;public class GetTest : MonoBehaviour{    public Text text;    void Start()    {        StartCoroutine(GetTesting());    }    IEnumerator GetTesting()     {        UnityWebRequest webRequest = UnityWebRequest.Get("https://google.com");        yield return webRequest.SendWebRequest();        text.text = webRequest.downloadHandler.text;    }}

9.滑鼠右键 "Hierachy" > "Create Empty" >
type "NetWorkManager"（得到名爲NetWorkManager的GameObject）
"Inspector">"Add Component">type"GetTest">附加GetTest.cs到"NetWorkManager"GameObject上>
拖曳"txt_Result"（txt_Result.text in "Hierachy"）到"GetTest（Script）">Text > None（Text）>
绑定成功
10.按下播放键测试> 如果 txt_Result.text 显示 "< !d octype html><html" 意味着成功连网.

使用 GUI

3.建立名爲NetWorkManager的GameObject,附加GetTest.cs
以下是 GetTest.cs 的代码：

using System.Collections;using UnityEngine;using UnityEngine.Networking;public class GetTest : MonoBehaviour{    private string downloadedText = "";    private Vector2 scrollPosition = Vector2.zero;    void Start()    {        StartCoroutine(GetTesting());    }    IEnumerator GetTesting()    {        UnityWebRequest webRequest = UnityWebRequest.Get("https://google.com");        yield return webRequest.SendWebRequest();        downloadedText = webRequest.downloadHandler.text;    }    private void OnGUI()    {        // Set the background box position and size        Rect backgroundRect = new Rect(Screen.width / 2 - 250,                                      Screen.height / 2 - 250, 500, 500);        // Draw the black background box        GUI.Box(backgroundRect, "", GUI.skin.box);        // Set the scroll view position and size        Rect scrollViewRect = new Rect(Screen.width / 2 - 240,                                       Screen.height / 2 - 240, 480, 480);        // Begin the scroll view        scrollPosition = GUI.BeginScrollView(scrollViewRect, scrollPosition,                                             new Rect(0, 0, 460, 1000));        // Draw the label with downloaded text        GUI.Label(new Rect(0, 0, 460, 1000), downloadedText);        // End the scroll view        GUI.EndScrollView();    }}

4.按下播放键测试> 如果GUI显示 "< !d octype html><html..." ,可滑动scrollbar看全文，意味着成功连网.

这样就成功创建了一个测试连网请求功能的测试 Unity专案。
