使用arduinoEDK通过esp8266调用nest api

我正在尝试使用 ESP8266 和 Arduino EDK 连接到 Nest_API（恒温器）。但至今还没有结果。

我以前见过有人在这里问过同样的问题。但他的问题的答案对我没有帮助。

这是我的代码：

Code

#include <ESP8266WiFi.h>
#include <WiFiClientSecure.h>

const char* ssid = "xxxxx";
const char* password = "xxxxx";

const char* host = "developer-api.nest.com";
const int httpsPort = 443;
const char* BearerKey = "xxxxxxxuB0QSbgw2nsT85dJEHRpwvR7rSyrLHm2E54QpC9vnSzB5PV8OtGDPm0mAh96wgM0MwApmS";

//declaring GPIO's
int gpio13Led = 13;
int gpio12Relay = 12;

// Use web browser to view and copy
// SHA1 fingerprint of the certificate
const char* fingerprint = "87:CB:F2:E6:44:C0:AA:F2:4C:28:B2:97:85:70:18:92:45:1B:A4:57";

void setup() {
// preparing GPIOs
  pinMode(gpio13Led, OUTPUT);
  digitalWrite(gpio13Led, HIGH);

  pinMode(gpio12Relay, OUTPUT);
  digitalWrite(gpio12Relay, HIGH);

  Serial.begin(115200);
  Serial.println();
  Serial.print("connecting to ");
  Serial.println(ssid);
  WiFi.mode(WIFI_STA);
  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }
  Serial.println("");
  Serial.println("WiFi connected");
  Serial.println("IP address: ");
  Serial.println(WiFi.localIP());

  // Use WiFiClientSecure class to create TLS connection
  WiFiClientSecure client;
  Serial.print("connecting to ");
  Serial.println(host);
  if (!client.connect(host, httpsPort)) {
    Serial.println("connection failed");
    return;
  }

  if (client.verify(fingerprint, host)) {
    Serial.println("certificate matches");
    digitalWrite(gpio13Led, LOW);
  } else {
    Serial.println("certificate doesn't match");
  }

  String url = "/";
  Serial.print("requesting URL: ");
  Serial.println(url);

  client.print(String("GET ") + url + " HTTP/1.1\r\n" +
               "Host: " + host + "\r\n" +
               "Content-Type: application/json\r\n" + 
               "Authorization: Bearer " + BearerKey + "\r\n\r\n"
               );

  Serial.println("request sent");
  while (client.connected()) {
    String line = client.readStringUntil('\n');
    Serial.println(line);
    if (line == "\r") {
      Serial.println("headers received");
      break;
    }
  }

 while (client.available()) {
    String line = client.readStringUntil('\n');
    Serial.println("reply was:");
    Serial.println("==========");
    Serial.println(line);
    Serial.println("==========");
    Serial.println("closing connection");
 }  
}

void loop() {
}   

我从来没有从服务器得到任何结果。但是当我使用邮递员时，它起作用了。所以我想知道。我需要使用“host:” + host + ... 行吗？

有没有办法捕获 WiFiClientSecure.h 库的一些错误。 我也曾经更改过 get 字符串中主机的 url。 然后我从服务器收到一个错误。毕竟有回应我已经很高兴了。

现在我完全陷入困境了。如果有人能进一步帮助我，那就太好了。谢谢

哇。天呐！我有回应了！你的提示使它工作@gre_gor。

我更改了主机名和端口，因为我的回复是这样的。

这是我的最终代码：

奇怪的是，我的指纹不匹配，但它仍然继续向我提供信息。

下一步是阅读此响应并使用我想要的数据。 :-)
