问题描述
我试图将此https://react-hook-form.com/get-started npm软件包与gatsby中的此软件包https://www.npmjs.com/package/react-google-recaptcha一起使用并做出反应。我想使用不可见的Recaptcha,它看起来像我必须通过创建react ref来执行的Recaptcha一样,但是它说rec.current为null,不引用确定该怎么做。 onSubmit函数是我得到空结果的地方,我假设我可以在此处触发验证码,然后取回验证码值,以后再在我的lambda函数中发送给Google进行验证。
提前谢谢
到目前为止,这是我的代码
import React,{ useState } from "react"
import Layout from "../components/layout"
import Img from "gatsby-image"
import { graphql,Link } from "gatsby"
import { CartItems } from "../components/cart"
import { useForm } from "react-hook-form"
import ReCAPTCHA from "react-google-recaptcha"
const StoreDetails = ({ data }) => {
const { register,handleSubmit,watch,errors } = useForm()
const recaptchaRef = React.createRef()
const onSubmit = data => {
console.log(recaptchaRef)
recaptchaRef.current.execute() //this shows up null
}
function onChange(value) {
console.log("Captcha value:",value)
}
function error(value) {
alert(value)
}
return (
<>
{data.allSanityProducts.edges.map(({ node: product },i) => {
return (
<React.Fragment key={i}>
<Item>
<Img
fluid={product.featureImage && product.featureImage.asset.fluid}
/>
<div>
...
<form onSubmit={handleSubmit(onSubmit)}>
{/* register your input into the hook by invoking the "register" function */}
<input name="example" defaultValue="test" ref={register} />
{/* include validation with required or other standard HTML validation rules */}
<input
name="examplerequired"
ref={register({ required: true })}
/>
{/* errors will return when field validation fails */}
{errors.examplerequired && (
<span>This field is required</span>
)}
<ReCAPTCHA
className="captchaStyle"
sitekey="obsf"
onChange={onChange}
onErrored={error}
badge={"bottomright"}
size={"invisible"}
ref={recaptchaRef}
/>
<input type="submit" />
</form>
</div>
</Item>
</React.Fragment>
)
})}
{close && <CartItems />}
</>
)
}
const WithLayout = Component => {
return props => (
<>
<Layout>
<Component {...props} />
</Layout>
...
</>
)
}
export default WithLayout(StoreDetails)
export const query = graphql`
query StoreDeatailsQuery($slug: String!) {
...
}

解决方法
您永远不会在引用中填充任何值。最初在以下位置设置为空:
const recaptchaRef = React.createRef()
您必须等待Google响应为recaptchaRef
填充一个值。换句话说,您需要使用基于承诺的方法来使用executeAsync()
和async
函数来填充它:
const onSubmit = async (data) => {
const yourValue = await recaptchaRef.current.executeAsync();
console.log(yourValue)
}
您可以查看有关react-google-recaptcha
documentation中公开的props
的更多详细信息。
