通過這段代碼創建POST

void send_request(){ 
    //client.println("POST /tables/arduino_table HTTP/1.1"); 
    //client.println("Host: tremortest1.azurewebsites.net"); 
    //client.println("Content-Type: application/json"); 
    char value[]="IRTHE"; 
    Serial.print("sending "); 
    Serial.println(value); 

    // POST URI 
    sprintf(buffer, "POST /tables/%s HTTP/1.1", table_name); 
    client.println(buffer); 

    // Host header 
    sprintf(buffer, "Host: %s", server); 
    client.println(buffer); 

    // Azure Mobile Services application key 
    //sprintf(buffer, "ZUMO-API-VERSION: %s", ver); 
    //client.println(buffer); 

    // JSON content type 
    client.println("Content-Type: application/json"); 

    // POST body 
    sprintf(buffer, "{\"value\": %d}", value); 

    // Content length 
    client.print("Content-Length: "); 
    client.println(strlen(buffer)); 
}
