最开始 我使用的是http://api.ipify.org 提供 的API接口，
因为是http访问，实现非常容易。最近发现这个接口无法访问了，可能官方停止这个接口了。
- void getPublicIP()
- {
- http.begin(client, "http://api.ipify.org");
- Serial.print("[HTTP] GET...\n");
- int httpCode = http.GET();
- if (httpCode > 0) {
- // HTTP header has been send and Server response header has been handled
- Serial.printf("[HTTP] GET... code: %d\n", httpCode);
- // file found at server
- if (httpCode == HTTP_CODE_OK)
- {
- publicIP = http.getString();
- Serial.print("Your public IP address is: ");
- Serial.println(publicIP);
-
- // Optionally, use this IP address for further processing
- // For example, you can use this IP with a geolocation API to get your city name
- }
- }
- else
- {
- Serial.printf("[HTTP] GET... failed, error: %s\n", http.errorToString(httpCode).c_str());
- }
- http.end();
- }
这个地址是https开头的，直接替换无法访问的。
修改如下，解决了访问https问题，我自己做的网络天气日历又可以自动获取地理位置信息了。
- void getPublicIP()
- {
- WiFiClientSecure client_s;
- // 跳过证书验证（仅用于测试，生产环境建议配置根证书）
- client_s.setInsecure();
- // 发起HTTPS请求
- if (http.begin(client_s, "https://iplark.com/ipapi/public/ip"))
- {
- Serial.print("[HTTP] GET...\n");
- int httpCode = http.GET();
- if (httpCode > 0)
- {
- Serial.printf("[HTTP] GET... code: %d\n", httpCode);
- if (httpCode == HTTP_CODE_OK) {
- publicIP = http.getString();
- Serial.print("Your public IP address is: ");
- Serial.println(publicIP);
- }
- } else
- {
- Serial.printf("[HTTP] GET... failed, error: %s\n", http.errorToString(httpCode).c_str());
- }
- http.end();
- } else
- {
- Serial.println("[HTTP] Unable to connect");
- }
- }
