Javascript 如何获取从另一个组件返回的数据

我需要获取一个api并从React native中的一个文件中获取这些数据，我能够通过console.log（）获取获取api的文件中的数据

API.js

---

商户列表.js

---

我在网上做了一些研究，发现可能是aysnc和Wait的问题，但我不知道如何修改代码

---

任何帮助都将不胜感激

修改您的函数，如下所示

export  const  merchastListFetch = ()=>{ 
return axios.get('http://myapi.com/API/fetch_all')
    .then(function (response) {
          return response.data;
    }).catch((error)=>{
        console.log(error)
    })
}

您可以将响应保存为数组状态，然后在需要的地方调用和修改它

大概是这样的：

async CallApiFunc(){
await fetch("http://myapi.com/API/fetch_all")
.then(res => res.json())
.then(res => {
     console.log(JSON.stringify(res))
     this.setState({
     dataArray: res
})
})
.catch(err => console.log(err))
}

这需要一个

dataArray:[]

作为状态

之后，您可以在一个平面列表中显示入口，例如，也可以像修改state一样修改它们。

它向我显示了“意外令牌”错误，在第2行返回时，您可以提供此路由的后端定义吗

http://myapi.com/API/fetch_all

甚至是存储数据（如果需要存储的话）

{"status":true,"data":[{"shop_id":"1","merchant_id":"1","area_id":"0","agent_id":"1","business_type_id":"1","business_category_id":"1","bill_type_id":"1","currency_id":"0","status_id":"0","register_name":"Dummy Name","register_no":"123456789","retail_name":"Test Only","description":"TESTING USE","commission":"20.00","gst_no":"12345","coming_soon":"0","is_halal":"0","is_active":"1","delivery_charge":"3.50","remarks":"TESTING USE AGAIN","approved_date":"0000-00-00 00:00:00","deleted":"0","created_date":"2020-10-06 15:02:20","created_by":"1","modified_date":"2020-10-08 09:37:53","modified_by":"1","merchant":"Merchant","shop_image":[{"shop_image_id":"3","shop_id":"1","file":"\/images\/shop\/5af16e1c6554160a79bea005.png","file_size":"65124","file_type":"image\/png","is_default":"1","is_active":"1","deleted":"0","created_date":"2020-10-09 13:21:23","created_by":"0","modified_date":"0000-00-00 00:00:00","modified_by":"0"}]},

export  const  merchastListFetch = ()=>{ 
return axios.get('http://myapi.com/API/fetch_all')
    .then(function (response) {
          return response.data;
    }).catch((error)=>{
        console.log(error)
    })
}

async CallApiFunc(){
await fetch("http://myapi.com/API/fetch_all")
.then(res => res.json())
.then(res => {
     console.log(JSON.stringify(res))
     this.setState({
     dataArray: res
})
})
.catch(err => console.log(err))
}
