http库中nest_api的https问题如何解决？

问答对人有帮助，内容完整，我也想知道答案 0 我正在尝试使用 http.get() 从我的恒温器获取数据，但我总是收到错误 307（重定向）。我开始认为它与我尝试连接的 https 网址有关。有没有人遇到过类似的问题，或者知道如何解决下面的问题？在此先感谢这是我的代码，在最后一部分中，您可以看到我正在尝试建立的与服务器的连接：代码：全选#include #include #include #include #define USE_SERIAL Serial String accessurl = "https://api.home.nest.com/oauth2/access_token"; MDNSResponder mdns; // My Network cred. const char* ssid = "Blanked out"; const char* password = "Blanked out"; int gpio13Led = 13; int gpio12Relay = 12; void setup(void){ // preparing GPIOs pinMode(gpio13Led, OUTPUT); digitalWrite(gpio13Led, HIGH); pinMode(gpio12Relay, OUTPUT); digitalWrite(gpio12Relay, HIGH); Serial.begin(115200); delay(5000); WiFi.begin(ssid, password); Serial.println(""); // Wait for connection while (WiFi.status() != WL_CONNECTED) { delay(500); Serial.print("."); } Serial.println(""); Serial.print("Connected to "); Serial.println(ssid); Serial.print("IP address: "); Serial.println(WiFi.localIP()); if (mdns.begin("esp8266", WiFi.localIP())) { Serial.println("MDNS responder started"); } } void loop(void){ Serial.println("Wifi Up - Test Start!"); delay(10000); if((WiFi.status() != WL_CONNECTED)) { Serial.println("wifi down"); return; } HTTPClient http; //Here I gave the footprint along with the url. But I'm not sure if it works. http.begin("https://developer-api.nest.com/", "87:CB:F2:E6:44:C0:AA:F2:4C:28:B2:97:85:70:18:92:45:1B:A4:57"); //http.addHeader("Cache-Control", "no-cache", true, true); //http.addHeader("Postman-Token", "419da1fa-6070-3338-c215-8be740891136", true, true); http.addHeader("Authorization", "Bearer c.blanked out", true, true); http.addHeader("Host", "developer-api.nest.com", true, true); http.addHeader("Content-Type", "application/json", false, true); int httpCode = http.GET(); Serial.println("request sent: n"); Serial.println(httpCode); //Doesn't seem to work? I never see any outprint. if (httpCode == HTTP_CODE_OK) { String payload = http.getString(); Serial.printf("[HTTP] GET response: %s", payload.c_str()); } else { String payload = http.getString(); String loc = http.header("Location"); Serial.printf("[HTTP] GE returned %d. kapot, error: %s; response: %s, new location: %sn", httpCode, http.errorToString(httpCode).c_str(), payload.c_str(), loc.c_str()); } http.end(); } 0
