我想通过 Saleor 电子商务平台提供的 GraphQL API 创建一个结帐对象。
根据 gql 游乐场,有一个突变可以这样做,它需要一个 CheckoutCreateInput 对象作为它的参数。
这是一个在操场上运行良好的示例突变。
这是我尝试过的当前代码(我在 vuex 操作中执行此操作)
export const actions = {
addToCart({ commit, dispatch }, cartItem) {
const currentCartItems = this.state.cartItems
// Check to see if we already have a checkout object
if (this.state.checkoutId !== '') {
// Create a new checkout ID
console.log('creating new checkout object')
try {
this.app.apolloProvider.defaultClient
.mutate({
mutation: CREATE_CART_MUTATION,
variables: {
checkoutInput: {
lines: { quantity: 10, variantId: 'UHJvZHVjdFZhcmlhbnQ6NQ==' },
email: 'test@test.com'
}
}
})
.then(({ data }) => {
console.log(data)
})
} catch (e) {
console.log(e)
}
} else {
console.log('checkout id already set')
}
// TODO: Check to see if the cart already contains the current Cart Item
commit('ADD_CART_ITEM', cartItem)
}
这是 CREATE_CART_MUTATION:
import gql from 'graphql-tag'
export const CREATE_CART_MUTATION = gql`
mutation($checkoutInput: CheckoutCreateInput!) {
checkoutCreate(input: $checkoutInput) {
checkout {
id
created
lastChange
lines {
id
variant {
id
name
}
quantity
totalPrice {
gross {
localized
}
net {
localized
}
}
}
totalPrice {
gross {
localized
}
net {
localized
}
}
}
}
}
`
在服务器上,这会返回以下错误:
graphql.error.base.GraphQLError: Variable "$checkoutInput" got invalid value {"email": "test@test.com", "lines": {"quantity": 10, "variantId": "UHJvZHVjdFZhcmlhbnQ6NQ=="}}.
In field "lines": In element #0: Expected "CheckoutLineInput", found not an object.
