uniapp implements ios payment

In recent years, the development of mobile Internet has provided a broader space for mobile payment. Mobile payment has become an important part of people's lives, and iOS, as an important platform for mobile payment, has naturally become the focus of developers. This article will introduce how to implement iOS payment through uniapp.

1. Introduction to iOS payment methods

Before implementing iOS payment, we need to understand several methods of iOS payment:

1. Apple in-app purchase payment (IAP)

Apple in-app purchase payment means that when users see a list of in-app purchase items, users can use in-app purchases (IAP) to purchase these applications. This method can verify the identity and purchase information of the application through Apple servers.

2. Third-party payment

Third-party payment refers to other payment methods other than Apple’s in-app purchase payment. Third-party payments can be added to our app by cooperating with other payment institutions.

2. Uniapp implements iOS payment

In uniapp, we can use the uni-app payment plug-in to implement iOS payment. The uni-app payment plug-in supports WeChat payment, Alipay payment, UnionPay payment, Apple in-app purchase payment and other payment methods.

1. Integrate the uni-app payment plug-in

First, we need to integrate the uni-app payment plug-in in the uniapp project. You can open the plug-in manager in HBuilderX, search for "uniapp payment", and then install and introduce the plug-in.

2. Add an application to the Apple Developer Backend

Before adding an application to the Apple Developer Backend, you first need to create a developer account in the Developer Center. After creating a developer account, we can enter the "Certificates, Identifiers and Profiles" page. In this page we need to register the application and create certificates and profiles so that we can pay using Apple In-App Purchase.

3. Set app payment permissions

In iOS, developers need to set relevant payment permissions in the application so that users can pay. During the integration of the uni-app payment plug-in, we need to set the following payment permissions:

1) NSAppleMusicUsageDescription: used to describe the reason why the application accesses the Apple Music Library.

2) NSPhotoLibraryAddUsageDescription: Allows the application to add photos to the album.

3) NSPhotoLibraryUsageDescription: Used to describe the reason why the application accesses the photo album.

4) NSCameraUsageDescription: Used to describe the reason why the application accesses the camera.

The above permissions are necessary for applications to access Apple device resources and do not require special processing.

4. Implementing the payment function

In uniapp, we can implement the payment function through the api interface provided by the uniapp payment plug-in. We need to introduce the uni-app payment plug-in into uniapp and choose different payment methods according to merchant needs. For example, if you need to use Apple Pay, you can implement it through the following code:

import uniPay from '@/plugins/uniPay'

uniPay.pay('iap', {
    transactionId: 'xxxx',
    productId: 'xxxx',
    quantity: '1',
    applicationUsername: 'xxxx',
    receiveReceipt: true,
    sandbox: false
})
.then(res => {
    console.log('支付成功');
    console.log(res);
})
.catch(err => {
    console.log('支付失败');
    console.log(err);
})

By passing parameters into the uniPay.pay method, you can implement the iOS payment function. Among them, transactionId represents the transaction ID, productId represents the product ID, quantity represents the quantity of the product, applicationUsername represents the user name of the application, receiveReceipt represents whether to receive a purchase receipt, and sandbox represents whether to pay in a sandbox environment.

Summary

This article briefly introduces uniapp’s method of implementing iOS payment. When implementing iOS payment, we need to integrate the uniapp payment plug-in, set payment permissions, and then use the API interface to implement the payment function. Through the above methods, developers can quickly implement iOS payment in the uniapp project and add convenient payment methods to the application.
