PHP示例使用说明

该示例适用于PHP编程语言，可以调用所有OpenAPI接口。示例封装了执行集成的过程，包括添加和验证调用支付网关API的签名。这只是一个例子，我们不保证代码适用于任何编程环境。它只是演示如何调用我们的API。您可以参考此代码来编写自己的程序。

使用条件​

适用于PHP 5.5以上的开发环境。

下载地址​

使用步骤​

1. 添加依赖项，使用“Composer”下载以下包​

{
    "require": {
        "ext-json": "*",
        "ext-openssl": "*",
        "ext-curl": "*"
    }
}

'ext-curlL' is used for packets sent over the HTTP network, 'ext-json' parses and processes JSON packets, and 'ext-openssl' is used for RSA signature calculation packets.

2. 请参阅GitHub示例代码并编写您的程序。以下是关键代码​

    // 1. Global parameter settings
    $appRsaPrivateKeyPem = "<YOUR APP RSA PRIVATE KEY>";
    $gatewayRsaPublicKeyPem = "<YOUR GATEWAY RSA PUBLIC KEY>";
    $gatewayUrl = "<YOUR GATEWAY URL>";
    $appId = "<YOUR APP ID>";

    // 2. Set parameters
        // Common parameters
    $parameters["app_id"] = $appId;
    $parameters["charset"] = "UTF-8";
    $parameters["format"] = "JSON";
    $parameters["sign_type"] = "RSA2";
    $parameters["version"] = "1.0";
    $parameters["timestamp"] = getMillisecond();
    $parameters["method"] = "order.query";
        // API owned parameters
    $parameters["merchant_no"] = "312100000164";
    $parameters["merchant_order_no"] = "TEST_1685946062143";

    // 3. Build a string to be signed
    $stringToBeSigned = buildToBeSignString($parameters);
    echo "StringToBeSigned : " . $stringToBeSigned;
    echo "</br></br>";

    // 4. Calculate signature
    $sign = generateSign($stringToBeSigned, $appRsaPrivateKeyPem);
    $parameters["sign"] = $sign;

    // 5. Send HTTP request
    $jsonString = json_encode($parameters);
    echo "Request to gateway[" . $gatewayUrl . "] send data  -->> " . $jsonString;
    echo "</br></br>";
    $responseStr = json_post($gatewayUrl, $jsonString);
    echo "Response from gateway[" . $gatewayUrl . "] receive data <<-- " . $responseStr;
    echo "</br></br>";

    // 6. Verify the signature of the response message
    $respObject = json_decode($responseStr, true);
    $respStringToBeSigned  = buildToBeSignString($respObject);
    echo "RespStringToBeSigned  : " . $respStringToBeSigned;
    echo "</br></br>";
    $respSignature = $respObject["sign"];
    $verified = verify($respStringToBeSigned, $respSignature, $gatewayRsaPublicKeyPem);

    echo "SignVerifyResult  : " . $verified;
    echo "</br></br>";
