一般我们与后端对接的时候会用到UnityWebRequest
这里简单使用这个与后端进行交互
这个是总类
using UnityEngine;
using System.Collections;
using System.Collections.Generic;
using System;
using UnityEngine.Networking;
public enum EOPERATION
{
LOGIN = 0,//登录
REGISTER,//注册
COLLEGELIST, //学院
MAJORLIST, //专业
CLASSLIST,//班级
EXISTMAIL,//邮箱重复验证
EXISTNUMBER, //学号重复验证
GETPASSWORD,//忘记密码
ADDSCORE,//添加成绩
DownLoad,
}
public class CallBackUser
{
public bool success;
public string msg;
public User obj;
}
public class WebWork : MonoBehaviour
{
Dictionary<EOPERATION, Action<string, DownloadHandler>> _handers = new Dictionary<EOPERATION, Action<string, DownloadHandler>>();
private string filepath;
bool isStartDownload;
UnityWebRequest request;
//根据协议号获取地址后缀
Dictionary<EOPERATION, string> mURLs = new Dictionary<EOPERATION, string>{
{ EOPERATION.LOGIN,"webapi/login" },
{ EOPERATION.REGISTER,"webapi/register"},
{ EOPERATION.COLLEGELIST,"user/college/list_combo"},
{ EOPERATION.MAJORLIST,"user/major/list_combo"},
{ EOPERATION.CLASSLIST,"user/class/list_combo"},
{ EOPERATION.EXISTMAIL,"webapi/existemail"},
{ EOPERATION.EXISTNUMBER,"webapi/existnumber"},
{EOPERATION.GETPASSWORD, "webapi/forget_pass"},
{EOPERATION.ADDSCORE,"webapi/add_score"},
{EOPERATION.DownLoad,"" }
};
private string ipAddress = "http://192.168.40.153:8000/";
AccountHander accountHander = new AccountHander();
public object JsonConvert { get; private set; }
//在这里注册消息返回后分发处理
public void Init()
{
accountHander.RegisterMsg(_handers);
DontDestroyOnLoad(this);
}
///
/// 传输数据
///
///
///
public void SendPost(EOPERATION op, Dictionary<string, string> dic)
{
//根据协议号获取完整路径
string url = ipAddress + mURLs[op];
StartCoroutine(Post(url, dic, op));
}
///
/// 获取数据
///
///
public void SendGet(EOPERATION op, string name = "")
{
string url = ipAddress + mURLs[op] + "/" + name;
StartCoroutine(Get(url, op, name));
}
///
/// 获取下载进度
///
///
public float GetProgress()
{
if (request == null || !isStartDownload)
return 0;
return request.downloadProgress;
}
private IEnumerator Get(string url, EOPERATION op, string name)
{
if (!string.IsNullOrEmpty(url))
{
using (request = UnityWebRequest.Get(url))
{
isStartDownload = true;
//设置超时 链接超时返回 且isNetworkError为true
request.timeout = 30;
yield return request.SendWebRequest();
isStartDownload = false;
//结果回传给具体实现
if (request.isHttpError || request.isNetworkError)
{
Debug.Log(request.error);
}
else
{
_handersop;
}
};
}
}
//private WWW http;
private IEnumerator Post(string url, Dictionary<string, string> dic, EOPERATION op)
{
if (!string.IsNullOrEmpty(url))
{
WWWForm form = new WWWForm();
foreach (var item in dic)
{
form.AddField(item.Key, item.Value);
}
using (request = UnityWebRequest.Post(url, form))
{
yield return request.SendWebRequest();
//结果回传给具体实现
if (request.isHttpError || request.isNetworkError)
{
Debug.Log(request.error);
}
else
{
_handersop;
}
}
}
}
}
工具类
using System.IO;
public class FileTool
{
///
/// 创建文件
///
public static void CreateFile(string filePath,byte[]bytes)
{
using (FileStream fs = new FileStream(filePath,FileMode.Create,FileAccess.Write))
{
fs.Write(bytes, 0, bytes.Length);
}
}
}
消息返回处理类 这只是一个分类
using Newtonsoft.Json;
using System;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.Networking;
public class AccountHander
{
public void RegisterMsg(Dictionary<EOPERATION, Action<string,DownloadHandler>> handers)
{
handers.Add(EOPERATION.LOGIN, OnRspLogin);
handers.Add(EOPERATION.REGISTER, OnRspRegister);
handers.Add(EOPERATION.DownLoad, OnRspDownLoad);
}
private void OnRspLogin(string name,DownloadHandler data)
{
//用Json转化为类内部数据
JsonConvert.DeserializeObject(data.text);
}
private void OnRspRegister(string name,DownloadHandler data)
{
}
private void OnRspDownLoad(string name,DownloadHandler data)
{
//data.data二进制的文件 视频 图片的信息
FileTool.CreateFile(name, data.data);
}
}
public void RegisterMsg(Dictionary<EOPERATION, Action<string,DownloadHandler>> handers)
{
}
如果想添加一个新的就在主类Init里注册 然后新类写一个注册方法就行了 这样会自动根据枚举转到相应的处理函数
然后name的话只是为了区分下载文件起码要改名吧 不然不知道名字 如果只是传数据可以无视name不调用
来用一个demo使用下
