to configure

The application for merchant account service is very troublesome. In order to quickly test, you can use the sandbox beta app, but currently only support Android phones

The service to be tested can only be tested after real name authentication and identity extension. In other words, you can fill in some personal information. It's very simple. I won't introduce it in detail here

Ant gold open platform
Ant gold sandbox beta


private_key private key

private_ The key is the private key of the merchant application. I download the Mac version (the download address of RSA signature tool). The format of generating the secret key should be PKCS1 (not JAVA), but I always fail to generate it here. I don't know if it's because of black apple_ T. So here's how I deal with it:

  1. Select the format of secret key first, pkcs8 (applicable to Java), and click generate secret key
  2. Copy the private key of the merchant application, click the format change and paste in the label column, click transfer to PKCS1 (non JAVA) private key, and the generated content is private in the configuration below_ Value of key

ali_public_key public key

Be careful, ali_public_key is not the public key generated by the RSA signature tool, but the RSA2 (SHA256) key Alipay public key in the background application of Alipay.

Get method:

  1. Click to generate the copied content of the public key file in the format conversion of RSA signature verification tool
  2. Enter the background, set the secret key of RSA2 (SHS256), apply the public key, and paste the content just copied

  1. After you save it, click the Alipay public key to get the Alipay public key.

configuration file

Create a new alipay.php file in the config directory to configure the following

return [
    'pay' => [
        // APPID
        'app_id' => '************',
        // When Alipay pays successfully, it will notify post server's address.
        'notify_url' => '',
        // After Alipay paid successfully, callback page get
        'return_url' => '',
        // The public key (note is Alipay's public key, not the merchant's public key).
        'ali_public_key' => '********',
        // Encryption method: * * RSA2 * * private key merchant application private key
        'private_key' => '********',
        'log' => [ // optional
            'file' => '../storage/logs/alipay.log',
            'level' => 'info', // It is recommended to adjust the production environment level to info and the development environment to debug
            'type' => 'single', // optional, daily
            'max_file' => 30, // optional, valid when the type is daily. The default is 30 days
        'http' => [
            'timeout' => 5.0,
            'connect_timeout' => 5.0,
            // Please refer to [guzzle] for more configuration items( )
        'mode' => 'dev', // optional, set this parameter to enter sandbox mode
