Post上传操作和Put上传操作

单例模式，封装方法上传文件

{// Start is called before the first frame updatevoid Start(){//高级操作指什么？// 在常用操作中我们使用的是 Unity 为我们封装好的一些方法// 我们可以方便的进行一些指定类型的数据获取// 比如// 下载数据时://1. 文本和二进制//2. 图片//3.AB 包// 如果我们想要获取其它类型的数据应该如何处理呢？// 上传数据时://1. 可以指定参数和值//2. 可以上传文件// 如果想要上传一些基于 HTTP 规则的其它数据应该如何处理呢？// 高级操作就是用来处理 常用操作不能完成的需求的// 它的核心思想就是: UnityWebRequest 中可以将数据处理分离开// 比如常规操作中我们用到的//DownloadHandlerTexture 和 DownloadHandlerAssetBundle 两个类// 就是用来将二进制字节数组转换成对应类型进行处理的// 所以高级操作时指 让你按照规则来实现更多的数据获取、上传等功能//关于UnityWebRequest的更多内容//1.构造函数UnityWebRequest request = new UnityWebRequest();//2.请求地址request.url = "服务器地址";//3.请求类型request.method = UnityWebRequest.kHttpVerbGET;//4.进度相关//request.downloadProgress;//request.uploadProgress//5.超时时间request.timeout = 50000;//6.上传下载字节数//request.uploadedBytes//request.downloadedBytes//7.重定向次数 设置为0标识不进行重定向  可以设置次数//request.redirectLimit = 0;//8.状态码 结果 错误内容//request.result;//request.responseCode;//request.error;//9.下载 上传处理对象//request.downloadHandler;//request.uploadHandler;//自定义获取数据 DownloadHandler 相关类// 关键类://1.DownloadHandlerBuffer 用于简单的数据存储，得到对应的二进制数据。//2.DownloadHandlerFile 用于下载文件并将文件保存到磁盘（内存占用少）。//3.DownloadHandlerTexture 用于下载图像。//4.DownloadHandlerAssetBundle 用于提取 AssetBundle。//5.DownloadHandlerAudioClip 用于下载音频文件。// 以上的这些类，其实就是 Unity 帮助我们实现好的，用于解析下载下来的数据的类// 使用对应的类处理下载数据，他们就会在内部将下载的数据处理为对应的类型，方便我们使用StartCoroutine(DownLoadTex());StartCoroutine(DownLoadAB());StartCoroutine(DownLoadAudioClip());//DownloadHandlerScript 是一个特殊类。就其本身而言，不会执行任何操作。// 但是，此类可由用户定义的类继承。此类接收来自 UnityWebRequest 系统的回调，// 然后可以使用这些回调在数据从网络到达时执行完全自定义的数据处理。StartCoroutine(DownLoadCustomHandler());}IEnumerator DownLoadTex(){UnityWebRequest request = new UnityWebRequest("http://192.168.80.1:8080/httpServer/lesson10.png");request.method= UnityWebRequest.kHttpVerbGET;//1.DownloadHandlerBuffer//DownloadHandlerBuffer handlerBuffer = new DownloadHandlerBuffer();//request.downloadHandler = handlerBuffer;//2.DownloadHandlerFile//DownloadHandlerFile  handlerFile = new DownloadHandlerFile(Application.persistentDataPath+"/downLoadfile.png");//request.downloadHandler = handlerFile;//3.DownloadHandlerTextureDownloadHandlerTexture handlerTexture = new DownloadHandlerTexture();request.downloadHandler = handlerTexture;yield return request.SendWebRequest();if (request.result == UnityWebRequest.Result.Success){//1.DownloadHandlerBuffer//获取字节数组//byte[] bytes = handlerBuffer.data;//3.DownloadHandlerTexture//Texture2D texture = handlerTexture.texture;}else{ }}IEnumerator DownLoadAB(){UnityWebRequest request = new UnityWebRequest("http://192.168.80.1:8080/httpServer/lua");request.method = UnityWebRequest.kHttpVerbGET;//第二个参数需要已知校检码 才能进行比较 检查完整性 如果不知道的话 只能传0 不进行完整性的检查//所有一般 只有进行AB包热更新时，服务器发送了对应的文件列表中包含了验证码才能进行检查DownloadHandlerAssetBundle downloadHandler = new DownloadHandlerAssetBundle(request.url,0);request.downloadHandler = downloadHandler;yield return request.SendWebRequest();if (request.result == UnityWebRequest.Result.Success){AssetBundle ab = downloadHandler.assetBundle;print(ab.name);}else{}}IEnumerator DownLoadAudioClip(){UnityWebRequest req = UnityWebRequestMultimedia.GetAudioClip("音效文件路径",AudioType.MPEG);yield return req.SendWebRequest();if (req.result == UnityWebRequest.Result.Success){AudioClip audioClip = DownloadHandlerAudioClip.GetContent(req);}else{}}IEnumerator DownLoadCustomHandler(){UnityWebRequest request = new UnityWebRequest();request.url = "http://192.168.80.1:8080/httpServer/xxx.png";request.method = UnityWebRequest.kHttpVerbGET;CustomDownLoadFileHandler customDownLoad = new CustomDownLoadFileHandler(Application.persistentDataPath + "/test.png");request.downloadHandler = customDownLoad;yield return request.SendWebRequest();if (request.result == UnityWebRequest.Result.Success){print("存储成功");}else{}}// Update is called once per framevoid Update(){}
