Php 为什么UnityWebRequest发送空字段？

我现在面临着一个令人沮丧的问题，我看不出这有什么理由不起作用，因为这是纯粹的Unity developer复制粘贴代码

我无法将数据从Unity发送到网站。每个Unity sent参数都被视为空

这就是我的

[Web.cs]

的样子：

using System.Collections;
using System.Collections.Generic;
using System.Linq;
using UnityEngine;
using UnityEngine.Networking;

public class Web : MonoBehaviour
{
    public IEnumerator Login(string Username, string Password)
    {
        Debug.Log(Username);
        Debug.Log(Password);

        WWWForm Form = new WWWForm();
        Form.AddField("loginUser", Username);
        Form.AddField("loginPass", Password);

        UnityWebRequest www = UnityWebRequest.Post("http://localhost/Login.php", Form);
        yield return www.SendWebRequest();

        if (www.isNetworkError || www.isHttpError)
            Debug.Log(www.error);
        else
        {
            Debug.Log("Form upload complete!");
            Debug.Log(www.downloadHandler.text);
        }
    }
}

<?php
    $UserName = $_GET["loginUser"];
    $Password = $_GET["loginPass"];
    
    $myfile = fopen("testfile.txt", "a");
    fwrite($myfile, "Username: $UserName\nPassowrd: $Password\n\n");
?>

我通过

Login.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class Login : MonoBehaviour
{
    public InputField UserName;
    public InputField Password;
    public Button myButton;

    private void Start()
    {
        myButton.onClick.AddListener(() =>
        {
            StartCoroutine(Main.Instance.Web.Login(UserName.text, Password.text));
        });
    }

}

php

代码如下所示：

using System.Collections;
using System.Collections.Generic;
using System.Linq;
using UnityEngine;
using UnityEngine.Networking;

public class Web : MonoBehaviour
{
    public IEnumerator Login(string Username, string Password)
    {
        Debug.Log(Username);
        Debug.Log(Password);

        WWWForm Form = new WWWForm();
        Form.AddField("loginUser", Username);
        Form.AddField("loginPass", Password);

        UnityWebRequest www = UnityWebRequest.Post("http://localhost/Login.php", Form);
        yield return www.SendWebRequest();

        if (www.isNetworkError || www.isHttpError)
            Debug.Log(www.error);
        else
        {
            Debug.Log("Form upload complete!");
            Debug.Log(www.downloadHandler.text);
        }
    }
}

<?php
    $UserName = $_GET["loginUser"];
    $Password = $_GET["loginPass"];
    
    $myfile = fopen("testfile.txt", "a");
    fwrite($myfile, "Username: $UserName\nPassowrd: $Password\n\n");
?>

看起来您正在向GET请求发送POST请求

---

Try:UnityWebRequest.Get（…）

您似乎正在向Get请求发送POST请求

试试：UnityWebRequest.Get（…）

@Kale，谢谢，我还是不明白post和Get方法的区别：-

对于未来的搜索者，我就是这样设法解决这个问题的：

public class Web : MonoBehaviour
{
    public IEnumerator Login(string Username, string Password)
    {
        WWWForm Form = new WWWForm();
        string Link = "http://localhost/Login.php?loginUser=" + Username + "&loginPass=" + Password;

        UnityWebRequest www = UnityWebRequest.Get(Link);
        yield return www.SendWebRequest();

        if (www.isNetworkError || www.isHttpError)
            Debug.Log(www.error);
        else
        {
            Debug.Log("Form upload complete!");
            Debug.Log(www.downloadHandler.text);
        }
    }
}

基本上，GET请求通过URL发送信息——更好地用于导航，post或多或少地在“幕后”发送信息——更好地用于登录信息。更多信息：基本上，GET请求通过URL发送信息-更好地用于导航，post或多或少地在“幕后”发送信息-更好地用于登录信息。更多信息：
