Question

我想使用以太网屏蔽从我的Apche服务器（localhost）发送/获取数据。

Ethernet(or Esp8266) ======(request.php by post method)==>>> server 
Ethernet(or Esp8266) <<<=====(respond header and data)==== server

我向服务器发送标头以获取数据。

在我的标题中：
如果我使用 连接：关闭 。这种方式似乎没问题。
但是当我使用 连接时：保持活着 。它无法连接或获取任何数据直到连接超时 这是我的标题以及将数据发送到服务器的方式：

String httpRequest(String data){
   String result="";
   if(client.connect(server, 80)){
    Serial.println("connected");

    client.println("POST /pihome1/getStatus.php HTTP/1.1");
    client.println("Host: localhost");
    client.println("Accept: *" "/" "*");
    client.println("Content-Length: " + String(data.length()));
    client.println("Content-Type: application/x-www-form-urlencoded");
    client.println("Connection: keep-alive");
    client.println();
    client.print(data);
  }
  else {
    //if you didn't get a connection to the server:
    Serial.println("connection failed");
  }
//Reading data
    unsigned long start = millis();
    int timeout = 2000;
    while (millis() - start < timeout){ 
      while (client.available()) {
        char c = client.read();
        result += c;
      }  
    }
  if (!client.connected()) {
    Serial.println();
    Serial.println("disconnecting.");
    client.flush();
    client.stop();
  }
   return result;
}

第一次成功后，直到超时连接才能连接。
