java - sun.net.httpserver太多字节无法写入流

我使用com.sun.net.httpserver.HttpServer编写了自己的小型http服务器

public void handle(HttpExchange t) throws IOException {
    OutputStream os = t.getResponseBody();
    os.write(generateResponse(t).getBytes());
    os.close();
}

如果我尝试写入输出流并且响应较大，则1024会出现以下异常:

java.io.IOException: insufficient bytes written to stream

最佳答案

这对我有用。

try {
    byte[] bs = responseString.getBytes("UTF-8");
    httpExchange.sendResponseHeaders(200, bs.length);
    OutputStream os = httpExchange.getResponseBody();
    os.write(bs);
} catch (IOException ex) {
    Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
}
