Question

我尝试从here修改基本的Arduino代码，以便将HTTP请求发送到AWS API Gateway。虽然链接中的示例代码有效，但我无法与AWS API Gateway成功建立连接。

我尝试了一些组合，例如从服务器[] 中移除 https：// ，将端口更改为 443 80 ，使用 client.connectSSL 而不是客户端从服务器[] 中删除 / beta .connect ，但到目前为止这些都没有。

该行： int err = client.connect（server，80）; 返回值为0。

AWS API网关没有设置证书，所以我不认为这是一个问题。 Wifi工作得很好。

非常感谢任何帮助！

///////please enter your sensitive data in the Secret tab/arduino_secrets.h
char ssid[] = SECRET_SSID;        // your network SSID (name)

use as key for WEP)
int keyIndex = 0;            // your network key Index number (needed only for WEP)

int status = WL_IDLE_STATUS;
// if you don't want to use DNS (and reduce your sketch size)
// use the numeric IP instead of the name for the server:
char server[] = "https://**********.execute-api.us-west-2.amazonaws.com/beta";    // name address for Google (using DNS)

WiFiClient client;

void setup() {
  //Initialize serial and wait for port to open:
  Serial.begin(9600);
  while (!Serial) {
   ; // wait for serial port to connect. Needed for native USB port only
  }

  // check for the presence of the shield:
  if (WiFi.status() == WL_NO_SHIELD) {
    Serial.println("WiFi shield not present");
    // don't continue:
    while (true);
  }

  // attempt to connect to WiFi network:
  while (status != WL_CONNECTED) {
    Serial.print("Attempting to connect to SSID: ");
    Serial.println(ssid);
    // Connect to WPA/WPA2 network. Change this line if using open or WEP network:
    status = WiFi.begin(ssid, pass);

    // wait 10 seconds for connection:
    delay(10000);
  }
  Serial.println("Connected to wifi");
  printWiFiStatus();

  Serial.println("\nStarting connection to server...");
  // if you get a connection, report back via serial:
  int err = client.connect(server, 80);
  Serial.println(err);
  if (err) {
    Serial.println("connected to server");
    // Make a HTTP request:
    client.println("GET /beta HTTP/1.1");
    client.println("Host: https://**********.execute-api.us-west-2.amazonaws.com");
    client.println("Connection: close");
    client.println();
  }
}

void loop() {
  // if there are incoming bytes available
  // from the server, read them and print them:
  while (client.available()) {
    char c = client.read();
    Serial.write(c);
  }

  // if the server's disconnected, stop the client:
  if (!client.connected()) {
    Serial.println();
    Serial.println("disconnecting from server.");
    client.stop();

    // do nothing forevermore:
    while (true);
  }
}


void printWiFiStatus() {
  // print the SSID of the network you're attached to:
  Serial.print("SSID: ");
  Serial.println(WiFi.SSID());

  // print your WiFi shield's IP address:
  IPAddress ip = WiFi.localIP();
  Serial.print("IP Address: ");
  Serial.println(ip);

  // print the received signal strength:
  long rssi = WiFi.RSSI();
  Serial.print("signal strength (RSSI):");
  Serial.print(rssi);
  Serial.println(" dBm");

提示：

（1）client.connect（fqdn，port）需要第一个参数的FQDN 文档中的示例为client.connect（“ Arduino.cc”，80），这在我的测试中似乎运行良好。文档说“ URL”，但它们表示FQDN。

（2）如果需要SSL，则必须使用固件更新程序加载证书第一。如果您将非标准引脚用于WiFi101板，则必须使用wifi.setPins（）设置引脚，否则固件更新程序将失败。 Adafruit Feather M0 1500的所有者会知道我在这里说什么。

我希望这会有所帮助。
