我从一个客户端向服务器发出两个请求,客户端挂起第二个方法httpclient.execute(httpPost);如果我为每个请求创建新客户端一切正常。如果我向谷歌发帖(例如)一切正常。有什么问题?
服务器:
public static void main(String[] args) throws IOException {
HttpServer server = HttpServer.create(new InetSocketAddress("localhost", 8080),2);
server.setExecutor(Executors.newFixedThreadPool(5));
HttpContext context = server.createContext("/", new GlobalHandler());
context.getFilters().add(new GlobalFilter());
server.createContext("/setup.exe", new GetFileHandler());
server.start();
}
private static class GlobalHandler implements HttpHandler {
@Override
public void handle(HttpExchange t) throws IOException {
Headers headers = t.getRequestHeaders();
System.out.println(headers.entrySet());
System.out.println(t.getHttpContext());
System.out.println(t.getRequestURI());
System.out.println(t.getProtocol());
System.out.println(t.getRequestMethod());
String resp = "Hello";
if (Objects.equals(t.getRequestMethod(), "POST")) {
System.out.println("POST");
Map params = (Map) t.getAttribute("parameters");
resp = params.toString();
System.out.println(params);
}
byte[] bytesToWrite = resp.getBytes("UTF-8");
t.sendResponseHeaders(200, bytesToWrite.length);
OutputStream os = t.getResponseBody();
os.write(bytesToWrite);
}
}
客户端:
RequestConfig requestConfig = RequestConfig.custom().setConnectTimeout(1 * 1000).build();
httpclient = HttpClientBuilder.create().setDefaultRequestConfig(requestConfig).build();
for(int i= 0;i<2;i++) {
HttpPost httpPost = new HttpPost("http://google.com");
httpPost.addHeader("Connection","keep-alive");
List<NameValuePair> nvps = new ArrayList<NameValuePair>();
nvps.add(new BasicNameValuePair("username", "вг"));
nvps.add(new BasicNameValuePair("password", "аб"));
httpPost.setEntity(new UrlEncodedFormEntity(nvps, "UTF-8"));
CloseableHttpResponse response2 = httpclient.execute(httpPost);
try {
System.out.println(response2.getStatusLine());
HttpEntity entity2 = response2.getEntity();
if(entity2.getContentLength() >0) {
byte[] content = new byte[(int) entity2.getContentLength()];
entity2.getContent().read(content);
System.out.println(new String(content, "UTF-8"));
}
EntityUtils.consume(entity2);
} finally {
response2.close();
}
}
httpclient.close();
