CVC 验证

在处理客户的 CVC 之前对其进行验证。

开始

若要集成验证功能，您必须创建一个 AccessCheckoutCardValidationListener 的实施。在 CvcValidationConfig 中传入安卓 UI 元素，以便使用 AccessCheckoutValidationInitialiser 来初始化验证。

完整示例集成：您可以在此处查看 CVC 验证集成的示例。

实施 AccessCheckoutCvcValidationListener

若要接收您客户的 CVC 验证结果，您必须创建您自己的 AccessCheckoutCvcValidationListener 实施。

package com.worldpay.access.checkout.sample.code

import com.worldpay.access.checkout.client.validation.listener.AccessCheckoutCvcValidationListener

class CvcValidationListener : AccessCheckoutCvcValidationListener {

    override fun onCvcValidated(isValid: Boolean) {
        //TODO: handle the cvc validation result
    }

    override fun onValidationSuccess() {
        //TODO: handle the form when the validation is complete i.e. all fields are valid
    }

}
package com.worldpay.access.checkout.sample.code

import com.worldpay.access.checkout.client.validation.listener.AccessCheckoutCvcValidationListener;

public class CvcValidationListener implements AccessCheckoutCvcValidationListener {

    @Override
    public void onCvcValidated(Boolean isValid) {
        //TODO: handle the cvc validation result
    }

    @Override
    public void onValidationSuccess() {
        //TODO: handle the form when the validation is complete i.e. all fields are valid
    }

}

功能和参数描述

方法描述
onCvcValidated该方法与 CVC 字段的有效性一起调用。 isValid 表示该字段是处于有效还是无效状态。
onValidationSuccess该方法在所有字段都处于有效状态时才调用。通常，您可以用它来启用提交按钮。

初始化 CVC 验证

在实施 AccessCheckoutCvcValidationListener 之后，您必须为视图初始化验证。为此，使用构造器来创建一个 CvcValidationConfig，如下所示。然后用它来初始化验证。

package com.worldpay.access.checkout.sample.code

// android library imports omitted

import com.worldpay.access.checkout.client.validation.AccessCheckoutValidationInitialiser
import com.worldpay.access.checkout.client.validation.config.CvcValidationConfig

class MainActivity : AppCompatActivity() {

    // fields omitted

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)

        val cvc = findViewById<EditText>(R.id.cvc)

        // other view references omitted

        val cvcValidationListener = CvcValidationListener()

        val cvcValidationConfig = CvcValidationConfig.Builder()
                .cvc(cvc)
                .validationListener(cvcValidationListener)
                .lifecycleOwner(this)
                .build()

        AccessCheckoutValidationInitialiser.initialise(cvcValidationConfig)

        //TODO: generate session here
    }

}
package com.worldpay.access.checkout.sample.code

// android library imports omitted

import com.worldpay.access.checkout.client.validation.AccessCheckoutValidationInitialiser;
import com.worldpay.access.checkout.client.validation.config.CvcValidationConfig;
import com.worldpay.access.checkout.client.validation.listener.AccessCheckoutCvcValidationListener;

public class MainActivity extends AppCompatActivity {

    // fields omitted

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        EditText cvc = findViewById<EditText>(R.id.cvc);

        // other view references omitted

        AccessCheckoutCvcValidationListener cvcValidationListener = CvcValidationListener();

        CvcValidationConfig cvcValidationConfig = CvcValidationConfig.Builder()
                .cvc(cvc)
                .validationListener(cardValidationListener)
                .lifecycleOwner(this)
                .build();

        AccessCheckoutValidationInitialiser.initialise(cvcValidationConfig);

        //TODO: generate session here
    }

}
