我需要发送与所有标准的RESTful方法和访问请求的主体的HTTP请求,以便发送/它接收JSON。 我进去看了看,
WebRequest.HttpWebRequest
这工作几乎完美,但有些情况下,例如,如果服务器停机功能的GetResponse可能需要几秒钟到return-,因为它是一个同步的方法 - 冷冻该期间的应用案例。 这种方法,BeginGetResponse的异步版本,似乎并没有异步工作(在Unity反正),因为它仍然冻结该期间的应用。
UnityEngine.WWW#
仅支持POST和GET一些reason-请求,但我还需要PUT和DELETE(标准的RESTful方法),所以我没有打扰寻找到它的任何进一步。
的System.Threading
为了不结冰我看着使用线程的应用程序运行WebRequest.HttpWebRequest.GetResponse。 线程似乎在编辑器中工作(但显得格外volatile-如果应用程序退出时它一直在编辑器中运行,甚至永远当你停止它不停止线程),当尽快建成iOS设备崩溃它当我试图启动一个线程(我忘了写下来的错误,我没有访问它现在)。
与桥梁,以统一的应用程序运行在原生iOS应用线程
可笑,甚至没有去尝试这个。
UniWeb
这个。 我想知道他们是怎么做的。
这里是WebRequest.BeginGetResponse方法,我想的一个例子,
// The RequestState class passes data across async calls.
public class RequestState
{
const int BufferSize = 1024;
public StringBuilder RequestData;
public byte[] BufferRead;
public WebRequest Request;
public Stream ResponseStream;
// Create Decoder for appropriate enconding type.
public Decoder StreamDecode = Encoding.UTF8.GetDecoder();
public RequestState()
{
BufferRead = new byte[BufferSize];
RequestData = new StringBuilder(String.Empty);
Request = null;
ResponseStream = null;
}
}
public class WebRequester
{
private void ExecuteRequest()
{
RequestState requestState = new RequestState();
WebRequest request = WebRequest.Create("mysite");
request.BeginGetResponse(new AsyncCallback(Callback), requestState);
}
private void Callback(IAsyncResult ar)
{
// Get the RequestState object from the async result.
RequestState rs = (RequestState) ar.AsyncState;
// Get the WebRequest from RequestState.
WebRequest req = rs.Request;
// Call EndGetResponse, which produces the WebResponse object
// that came from the request issued above.
WebResponse resp = req.EndGetResponse(ar);
}
}

好吧,我终于写我自己的解决方案 。 基本上,我们需要一个RequestState, 回调方法和超时线程 。 在这里我就复制什么在UnifyCommunity做 (现在叫unity3d维基)。 这是过时的代码,但比那里的东西,这样比较方便在这里显示更小的东西。 现在我已经删除(在unit3d维基) System.Action
和static
的性能和简单:
用法
static public ThisClass Instance;
void Awake () {
Instance = GetComponent<ThisClass>();
}
static private IEnumerator CheckAvailabilityNow () {
bool foundURL;
string checkThisURL = "http://www.example.com/index.html";
yield return Instance.StartCoroutine(
WebAsync.CheckForMissingURL(checkThisURL, value => foundURL = !value)
);
Debug.Log("Does "+ checkThisURL +" exist? "+ foundURL);
}

我线程对iOS-工作,我相信这是崩溃,由于鬼线什么的。 重新启动设备似乎有固定的崩溃,所以我就用WebRequest.HttpWebRequest与线程。
有异步这样做的方式,不使用的IEnumerator和收益回报的东西。 退房eDriven框架。
HttpConnector类: https://github.com/dkozar/eDriven/blob/master/eDriven.Networking/Rpc/Core/HttpConnector.cs
我在这个Web播放演示使用了与JsonFX所有HttpConnector的时间,例如: http://edrivenunity.com/load-images
没有PUT和DELETE是不是一个大问题,因为这一切可以使用GET和POST来完成。 举例来说,我成功地使用Drupal的CMS的REST服务进行通信。
// javascript in the web player not ios, android or desktop you could just run the following code:
var jscall:String;
jscall="var reqScript = document.createElement('script');";
jscall+="reqScript.src = 'synchmanager_secure2.jsp?userid="+uid+"&token="+access_token+"&rnd='+Math.random()*777;";
jscall+="document.body.appendChild(reqScript);";
Application.ExternalEval(jscall);
// cs
string jscall;
jscall="var reqScript = document.createElement('script');";
jscall+="reqScript.src = 'synchmanager_secure2.jsp?userid="+uid+"&token="+access_token+"&rnd='+Math.random()*777;";
jscall+="document.body.appendChild(reqScript);";
Application.ExternalEval(jscall);
// then update your object using the your return in a function like this
// json return object always asynch
function sendMyReturn(args){
var unity=getUnity();
unity.SendMessage("object", "function", args );
}
sendMyReturn(args);
或者你可以用这个通过AJAX功能发送预先编写自定义标题为安全起见,你需要签署头和签名的请求从服务器返回我喜欢MD5签名比较他们没有那么大
