nodeMCU用https怎么连接到新版onenet

Question

https://blog.csdn.net/qq_35653974/article/details/127249660，参考这篇文章，想连接onenet平台，返回是0。修改了WiFi账户密码，指纹和网址，还有哪里需要注意？

//把你需要调用的请求地址用浏览器访问，然后打开调试工具选择“安全”即可看到对应请求的fingerprint，复制到这个地方即可，类似于入网凭证一样

  String url = "/repos/esp8266/Arduino/commits/master/status";

  Serial.println("request sent");
  //等待服务器响应信息
  while (client.connected()) {
    String line = client.readStringUntil('\n'); //获取返回值
    if (line == "\r") {
      Serial.println("headers received");
      break;
    }
  }
  String line = client.readStringUntil('\n');
  if (line.startsWith("{\"state\":\"success\"")) { //判断检测返回的字符串是否包含该内容
    Serial.println("esp8266/Arduino CI successfull!");
  } else {

  }
  Serial.println("reply was:");
