ESP8266 带弹出窗口的强制门户

Question

有没有人成功地获得强制门户以导致重定向内容弹出到 Arduino 或 ESP8266 上的特定登录页面？ 我已经在阳光下尝试了一切，虽然我的 android 会抱怨未连接的互联网和其他东西，但它从来没有真正请求/建议打开浏览器，就像我在一些带有登录页面的开放式 wifi 热点上看到的那样. 我正在尝试实现实际上是非互联网连接设备，用户将在远程位置登录以显示他们已经到达，有点像 geocache 但使用 wifi 登录。我做了 dnsServer glob（所有名称到本地 IP），我做了一些 url 重定向。我尝试输入特定内容（而不是重定向），但没有弹出任何内容。

相关代码：

#include <ESPAsyncWebServer.h>
#include <ESP8266WiFi.h>
#include <DNSServer.h>
#include <ESP8266mDNS.h>


IPAddress apIp ( 10, 10, 10, 10 );
AsyncWebServer asyncWebServer(80);
DNSServer dnsServer;
const char* captiveRedirect = "/index.htm";
String apSSID = "GeoCache";

dnsServer.setErrorReplyCode(DNSReplyCode::NoError);
dnsServer.start ( DNS_PORT, "*", apIp );

DBG_OUTPUT_PORT.println("Initializing MDNS for local hostname on AP");
if (MDNS.begin(apHostname)) {
    MDNS.addService("http", "tcp", 80);
    DBG_OUTPUT_PORT.println("MDNS responder started");
    DBG_OUTPUT_PORT.print("You can now connect to http://");
    DBG_OUTPUT_PORT.print(apHostname);
    DBG_OUTPUT_PORT.println(".local");
}

//Android captive portal. Maybe not needed. Might be handled by notFound handler.
asyncWebServer.addRewrite( new AsyncWebRewrite("/generate_204", captiveRedirect));
//asyncWebServer.on ( "/generate_204", returnOK );
//Microsoft captive portal. Maybe not needed. Might be handled by notFound handler.
asyncWebServer.addRewrite( new AsyncWebRewrite("/fwlink", captiveRedirect));
//asyncWebServer.on ( "/fwlink", returnOK );
//Microsoft windows 10
//asyncWebServer.on ( "/connecttest.txt", returnOK );
asyncWebServer.addRewrite( new AsyncWebRewrite("/connecttest.txt", captiveRedirect));
// apple devices
asyncWebServer.addRewrite( new AsyncWebRewrite("/hotspot-detect.html", captiveRedirect));
//asyncWebServer.on ( "/hotspot-detect.html", returnOK );
asyncWebServer.addRewrite( new AsyncWebRewrite("/library/test/success.html", captiveRedirect));
//asyncWebServer.on ( "/library/test/success.html", returnOK );
// kindle
asyncWebServer.addRewrite( new AsyncWebRewrite("/kindle-wifi/wifistub.html", captiveRedirect));
//asyncWebServer.on ( "/kindle-wifi/wifistub.html", returnOK );

asyncWebServer.on("/delete", HTTP_DELETE, handleDelete);
// upload a file to /upload
asyncWebServer.on("/upload", HTTP_POST, returnOK, handleUpload);
// Catch-All Handlers
asyncWebServer.onFileUpload(handleUpload);
//asyncWebServer.onRequestBody(onBody);

asyncWebServer.on("/signin", HTTP_GET, addLog);

asyncWebServer.onNotFound(handleNotFound);

asyncWebServer.begin();

WiFi.mode(WIFI_AP);
WiFi.softAPConfig ( apIp, apIp, IPAddress ( 255, 255, 255, 0 ) );
WiFi.softAP(apSSID);

在循环（）中，你必须包括：

dnsServer.processNextRequest();

之前

server.handleClient(); //Handling of incoming requests

然后，创建一个未找到的路由器：

server.onNotFound([]() {
    char * msg = "HELLO<br>Default landing page<br>";
    server.send(200, "text/html", msg );
  });
