[Ethernet]
説明
Returns the number of bytes available for reading (that is, the amount of data that has been written to the client by the server it is connected to).available() inherits from the Stream utility class.
Syntax
EthernetClient client; client.available()
Parameters
none
Returns
The number of bytes available.
Example
#include <Ethernet.h>
byte ip[] = { 10, 0, 0, 177 };
byte server[] = { 64, 233, 187, 99 }; // Google
EthernetClient client;
void setup()
{
Ethernet.begin(NULL, ip);
Serial.begin(9600);
delay(1000);
Serial.println("connecting...");
if (client.connect(server, 80)) {
Serial.println("connected");
client.println("GET /search?q=arduino HTTP/1.0");
client.println();
} else {
Serial.println("connection failed");
}
}
void loop()
{
if (client.available()) {
char c = client.read();
Serial.print(c);
}
if (!client.connected()) {
Serial.println();
Serial.println("disconnecting.");
client.stop();
for(;;)
;
}
