使用前先创建并引入以下文件:
javascript
// uni iap
const ProviderType = {
IAP: 'iap'
}
const IapTransactionState = {
purchasing: "0", // A transaction that is being processed by the App Store.
purchased: "1", // A successfully processed transaction.
failed: "2", // A failed transaction.
restored: "3", // A transaction that restores content previously purchased by the user.
deferred: "4" // A transaction that is in the queue, but its final status is pending external action such as Ask to Buy.
};
class Iap {
_channel = null;
_channelError = null;
_productIds = [];
_ready = false;
constructor({
products
}) {
this._productIds = products;
}
init() {
return new Promise((resolve, reject) => {
this.getChannels((channel) => {
this._ready = true;
resolve(channel);
}, (err) => {
reject(err);
})
})
}
getProduct(productIds) {
return new Promise((resolve, reject) => {
this._channel.requestProduct(productIds || this._productIds, (res) => {
resolve(res);
}, (err) => {
reject(err);
})
});
}
requestPayment(orderInfo) {
return new Promise((resolve, reject) => {
uni.requestPayment({

orderInfo: orderInfo,
success: (res) => {
resolve(res);
},
fail: (err) => {
reject(err);
}
});
});
}
restoreCompletedTransactions(username) {
return new Promise((resolve, reject) => {
this._channel.restoreCompletedTransactions({
manualFinishTransaction: true,
username
}, (res) => {
resolve(res);
}, (err) => {

});
}
finishTransaction(transaction) {

}

return
}
uni.getProvider({
