在Arduino-Uno中GET请求失败
在Arduino-Uno中GET请求失败
提问于 2017-12-28 05:49:51
我正在尝试使用ESP8266和Arduino访问运行在Rpi服务器中的一个简单的网页。
我已经推荐了this similar SO question，但这不是解决我的问题的方法。
以下是我目前的Arduino代码：
#include "WiFiEsp.h"
// Emulate Serial1 on pins 6/7 if not present
#ifndef HAVE_HWSERIAL1
#include "SoftwareSerial.h"
SoftwareSerial Serial1(2,3); // RX, TX
#endif
char ssid[] = "RPi"; // your network SSID (name)
char pass[] = "raspberry"; // your network password
int status = WL_IDLE_STATUS; // the Wifi radio's status
char server[] = "192.168.50.1";
// Initialize the Ethernet client object
WiFiEspClient client;
void setup()
{
// initialize serial for debugging
Serial.begin(9600);
// initialize serial for ESP module
Serial1.begin(9600);
// initialize ESP module
WiFi.init(&Serial1);
// 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 WPA SSID: ");
Serial.println(ssid);
// Connect to WPA/WPA2 network
status = WiFi.begin(ssid, pass);
}
// you're connected now, so print out the data
Serial.println("You're connected to the network");
printWifiStatus();
Serial.println();
Serial.println("Starting connection to server...");
// if you get a connection, report back via serial
if (client.connect(server, 80)) {
Serial.println("Connected to server");
// Make a HTTP request
client.println("GET /simple.html HTTP/1.1");
client.println("Host: 192.168.50.1");
client.println("Connection: close");
client.println();
}
}
void loop()
{
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");
}输出：
Starting connection to server...
[WiFiEsp] Connecting to 192.168.50.1
Connected to server
[WiFiEsp] Data packet send error (2)
[WiFiEsp] Failed to write to socket 3
[WiFiEsp] Disconnecting 3我的simple.html看起来像这样。
<html>
<body>
<p>1</p>
</body>
</html>
}我从web浏览器访问这个页面，它正确地显示了内容。这里少了什么？
提前谢谢。

在代码中尝试这一行
client.print("GET /simple.html HTTP/1.0\r\n\r\n");页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
