生成唯一地址時如何放置二維碼？塊.io API
大家好，正如標題所說。每當 block_io.php 生成唯一地址時，如何生成二維碼？每當我回顯它時，我似乎在呼叫 $newAddressInfo 或 $newAddressInfo->data->address 時遇到問題。請忽略缺少的字元，因為它可以正常工作。這就是整個腳本。

我剛剛調整了凱爾的腳本。
腳本 ：
require_once ("block_io.php"); $apiKey = "myAPIkey"; <br> $version = 2; // API version <br> $pin = "myPin";<br> $block_io = new BlockIo($apiKey, $pin, $version);<br> if(isset($_POST['submit'])){ $newAddressInfo = $block_io->get_new_address(); $address = $_POST['addr']; $decoded = decodeBase58($address); $d1 = hash("sha256", substr($decoded,0,21), true); $d2 = hash("sha256", $d1, true); if(substr_compare($decoded, $d2, 21, 4)){ $message = "Invalid Bitcoin Address"; } else { $message1 = "Valid Address"; $message2 = "Your Receiving Address : "; } } function decodeBase58($input) { $alphabet = "123456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz"; $out = array_fill(0, 25, 0); for($i=0;$i<strlen($input);$i++){ if(($p=strpos($alphabet, $input[$i]))===false){ throw new \Exception("invalid character found"); } $c = $p; for ($j = 25; $j--; ) { $c += (int)(58 * $out[$j]); $out[$j] = (int)($c % 256); $c /= 256; $c = (int)$c; } if($c != 0){ throw new \Exception("address too long"); } } $result = ""; foreach($out as $val){ $result .= chr($val); } return $result; } </form method="post"> <input style="width: 100%;" name="addr" type="text"> <center><input name="submit" type="submit"><br> if (isset($message)){ echo $message; } <br> if (isset($message2)){ echo " Your Unique Deposit Address: " .$newAddressInfo->data->address."<br>"; } <br> if (isset($message2)) $str = "Your Receiving Address : "; $str ; echo $address = $_POST['addr']; <br> if (isset($message2)){ echo img src='qr/qr_img.php?d=$newAddressInfo->data->address'> ; } <br> </form>

您需要做的就是創建新地址，然後將地址放入二維碼中。您可以使用 Google Charts API
<?php require_once("block_io.php"); $block_io = new BlockIo($apiKey, $pin, $version); $createAddress = $block_io->get_new_address(); $address = $createAddress->data->address; ?> <html> This is your new address: <br> <img src="http://chart.googleapis.com/chart?chs=125x125&cht=qr&chl=<?php echo $address; ?>"> </html>
