简单来说,就是在UWP中做一个支持GET请求简单的Web Server,本实例UWP(server) 与 Winform(client) 在同一机子将无法通讯,但UWP(server)写client代码可调用调试。

注意,Package.appxmanifest 选项“功能”卡中的Internet配置。

Below is some code for a simple HTTP server for Metro/Modern-style Windows 8 apps. This code supports GET requests for a resource located at the root-level (e.g. http://localhost:8000/foo.txt) and looks for the corresponding file in the Data directory of the app package. This might be useful for unit testing, among other things.

public class HttpServer : IDisposable {
private const uint BufferSize = ;
private static readonly StorageFolder LocalFolder
= Windows.ApplicationModel.Package.Current.InstalledLocation; private readonly StreamSocketListener listener; public HttpServer(int port) {
this.listener = new StreamSocketListener();
this.listener.ConnectionReceived += (s, e) => ProcessRequestAsync(e.Socket);
this.listener.BindServiceNameAsync(port.ToString());
} public void Dispose() {
this.listener.Dispose();
} private async void ProcessRequestAsync(StreamSocket socket) {
// this works for text only
StringBuilder request = new StringBuilder();
using(IInputStream input = socket.InputStream) {
byte[] data = new byte[BufferSize];
IBuffer buffer = data.AsBuffer();
uint dataRead = BufferSize;
while (dataRead == BufferSize) {
await input.ReadAsync(buffer, BufferSize, InputStreamOptions.Partial);
request.Append(Encoding.UTF8.GetString(data, , data.Length));
dataRead = buffer.Length;
}
} using (IOutputStream output = socket.OutputStream) {
string requestMethod = request.ToString().Split('\n')[];
string[] requestParts = requestMethod.Split(' '); if (requestParts[] == "GET")
await WriteResponseAsync(requestParts[], output);
else
throw new InvalidDataException("HTTP method not supported: "
+ requestParts[]);
}
} private async Task WriteResponseAsync(string path, IOutputStream os) {
using (Stream resp = os.AsStreamForWrite()) {
bool exists = true;
try {
// Look in the Data subdirectory of the app package
string filePath = "Data" + path.Replace('/', '\\');
using (Stream fs = await LocalFolder.OpenStreamForReadAsync(filePath)) {
string header = String.Format("HTTP/1.1 200 OK\r\n" +
"Content-Length: {0}\r\n" +
"Connection: close\r\n\r\n",
fs.Length);
byte[] headerArray = Encoding.UTF8.GetBytes(header);
await resp.WriteAsync(headerArray, , headerArray.Length);
await fs.CopyToAsync(resp);
}
}
catch (FileNotFoundException) {
exists = false;
} if (!exists) {
byte[] headerArray = Encoding.UTF8.GetBytes(
"HTTP/1.1 404 Not Found\r\n" +
"Content-Length:0\r\n" +
"Connection: close\r\n\r\n");
await resp.WriteAsync(headerArray, , headerArray.Length);
} await resp.FlushAsync();
}
}
}

Usage:

const int port = ;
using (HttpServer server = new HttpServer(port)) {
using (HttpClient client = new HttpClient()) {
try {
byte[] data = await client.GetByteArrayAsync(
"http://localhost:" + port + "/foo.txt");
// do something with
}
catch (HttpRequestException) {
// possibly a 404
}
}
}

Notes:

  • The app manifest needs to declare the "Internet (Client & Server)" and/or the "Private Networks (Client & Server)" capability.
  • Due to the Windows 8 security model:
    • A Metro app can access network servers within its own process.
    • A Metro app Foo can access network servers hosted by another Metro app Bar iff Foo has a loopback exemption. You can use CheckNetIsolation.exe to do this. This is useful for debugging only, as it must be done manually.
    • A Desktop app cannot access network servers hosted by a Metro app. The BackgroundDownloader appears to fall into this category even though that is an API available to Metro apps.
