在写这篇的时候提到过一个数据传输工具，但是当时是别人的东西，只写了两个例子，这里稍微整理一下，变成一个静态类工具，可以直接和服务器Get、Post、Delete等请求。
还是先讲使用方法：
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Test : MonoBehaviour
{
void Start()
{
//服务的地址接口
string url = "http://192.168.222.222:8080/api/base/common/login";
//直接Get请求，onError和onSuccess为回调
WebRequests.Get(url, onError, onSuccess);
//如果需要添加header
Dictionary<string, string> headers = new Dictionary<string, string>();
headers.Add("Authentication", "Authentication");
WebRequests.Get(url, onError, onSuccess, headers);
//Post请求案例
WWWForm form = new WWWForm();
form.AddField("phone", "11111111111");
form.AddField("password", "111111");
WebRequests.Post(url, form, onError, onSuccess);
}
void onSuccess(string log)
{
Debug.Log("onSuccess:" + log);
}
void onError(string log)
{
Debug.Log("onError:" + log);
}
}
然后是静态类工具代码：
using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.Networking;
/// <summary>
/// 网络请求类，四种请求方式区别可参考：https://blog.csdn.net/u010305706/article/details/51259649?utm_medium=distribute.pc_relevant.none-task-blog-BlogCommendFromBaidu-4.channel_param&depth_1-utm_source=distribute.pc_relevant.none-task-blog-BlogCommendFromBaidu-4.channel_param
/// 常用的可能就是Get和Post，有时候也会用到Delete
/// </summary>
public static class WebRequests
{
//WebRequests本身不继承MonoBehaviour，但调用IEnumerator协程需要MonoBehaviour
//因此使用WebRequestsMonoBehaviour来调用StartCoroutine
private class WebRequestsMonoBehaviour : MonoBehaviour { }
private static WebRequestsMonoBehaviour webRequestsMonoBehaviour;
//用于调用前防止未生成实例，可以通过统一的单例再优化一下
private static void Init()
{
if (webRequestsMonoBehaviour == null)
{
GameObject gameObject = new GameObject("WebRequests");
webRequestsMonoBehaviour = gameObject.AddComponent<WebRequestsMonoBehaviour>();
}
}
//外部直接调用此处的Get函数，通过委托处理onError和onSuccess事件
public static void Get(string url, Action<string> onError, Action<string> onSuccess, Dictionary<string, string> headers = null)
{
Init();
webRequestsMonoBehaviour.StartCoroutine(IEGet(url, headers, onError, onSuccess));
}
private static IEnumerator IEGet(string url, Dictionary<string, string> headers, Action<string> onError, Action<string> onSuccess)
{
//因为UnityWebRequest继承IDisposable接口，参考https://www.cnblogs.com/wyt007/p/9304564.html
//因此需要使用using关键字来控制资源的释放
//我们在写一些临时变量并且希望用完即释放它的时候也可以去继承IDisposable接口
using (UnityWebRequest unityWebRequest = UnityWebRequest.Get(url))
{
if (headers != null)
{
Debug.Log(headers.Count);
foreach (var header in headers)
{
unityWebRequest.SetRequestHeader(header.Key, header.Value);
}
}
unityWebRequest.method = UnityWebRequest.kHttpVerbGET;
yield return unityWebRequest.SendWebRequest();
if (unityWebRequest.isNetworkError || unityWebRequest.isHttpError)
{
onError(unityWebRequest.error);
}
else
{
onSuccess(unityWebRequest.downloadHandler.text);
}
}
}
public static void Delete(string url, Action<string> onError, Action<string> onSuccess, Dictionary<string, string> headers = null)
{
Init();
webRequestsMonoBehaviour.StartCoroutine(IEDelete(url, headers, onError, onSuccess));
}
private static IEnumerator IEDelete(string url, Dictionary<string, string> headers, Action<string> onError, Action<string> onSuccess)
{
using (UnityWebRequest unityWebRequest = UnityWebRequest.Delete(url))
{
if (headers != null)
{
foreach (var header in headers)
{
unityWebRequest.SetRequestHeader(header.Key, header.Value);
}
}
unityWebRequest.method = UnityWebRequest.kHttpVerbDELETE;
yield return unityWebRequest.SendWebRequest();
if (unityWebRequest.isNetworkError || unityWebRequest.isHttpError)
{
onError(unityWebRequest.error);
}
else
{
onSuccess(unityWebRequest.downloadHandler.text);
}
}
}
public static void Post(string url, WWWForm postData, Action<string> onError, Action<string> onSuccess, Dictionary<string, string> headers = null)
{
Init();
webRequestsMonoBehaviour.StartCoroutine(IEPost(url, postData, headers, onError, onSuccess));
}
private static IEnumerator IEPost(string url, WWWForm postData, Dictionary<string, string> headers, Action<string> onError, Action<string> onSuccess)
{
using (UnityWebRequest unityWebRequest = UnityWebRequest.Post(url, postData))
{
if (headers != null)
{
foreach (var header in headers)
{
unityWebRequest.SetRequestHeader(header.Key, header.Value);
}
foreach (var header in headers)
{
Debug.Log(unityWebRequest.GetRequestHeader(header.Key));
}
}
unityWebRequest.method = UnityWebRequest.kHttpVerbPOST;
yield return unityWebRequest.SendWebRequest();
if (unityWebRequest.isNetworkError || unityWebRequest.isHttpError)
{
onError(unityWebRequest.error);
}
else
{
onSuccess(unityWebRequest.downloadHandler.text);
}
}
}
public static void Put(string url, string putData, Action<string> onError, Action<string> onSuccess, Dictionary<string, string> headers = null)
{
Init();
webRequestsMonoBehaviour.StartCoroutine(IEPut(url, putData, headers, onError, onSuccess));
}
private static IEnumerator IEPut(string url, string putData, Dictionary<string, string> headers, Action<string> onError, Action<string> onSuccess)
{
using (UnityWebRequest unityWebRequest = UnityWebRequest.Put(url, putData))
{
if (headers != null)
{
foreach (var header in headers)
{
unityWebRequest.SetRequestHeader(header.Key, header.Value);
}
}
unityWebRequest.method = UnityWebRequest.kHttpVerbDELETE;
yield return unityWebRequest.SendWebRequest();
if (unityWebRequest.isNetworkError || unityWebRequest.isHttpError)
{
onError(unityWebRequest.error);
}
else
{
onSuccess(unityWebRequest.downloadHandler.text);
}
}
}
}
这里仅写了普通的交互方法，未写一些资源的请求方法，如果有需要的小伙伴，可以自行参考这篇里的内容扩展该工具。
