Laravel Vue SPA：如何从 Laravel 中正确检索 json 对象并测试将其打印到 Vue 组件内的 console.log()？

json 对象在 somedomain.com/channellist 处正确可用。然后由 axios.

检索

如有任何帮助，我们将不胜感激。

Vue 组件：

<template>
    <div id="app">      
            <vue-chat :channels="channels"></vue-chat>  
    </div>
</template>

<script>

  export default {
 
    data() {
      return {
        
        channels: {},
        
      }
    },
   
   methods: {
    
        getChannels(){
            this.loading = true
            var url = "/channellist"
                
            axios
              .get(url)
              .then(response => (this.channels = response.data.channels))
            },     
    },
    
    watch: {

    },
    
    components: {
     
    },
    
    created() {
     
      this.getChannels()
   
    }
  }
</script>
<style>
    #app {
        margin-left: 1em;
    }

    .heading h1 {
        margin-bottom: 0;
    }
</style>

json 从 Laravel 返回的对象 somedomain.com/channellist:

{"channels":[{"id":1,"name":"channel 1","created_at":"2020-07-10T06:03:14.000000Z","updated_at":"2020-07-10T06:03:14.000000Z"},{"id":2,"name":"channel 2","created_at":"2020-07-10T06:03:14.000000Z","updated_at":"2020-07-10T06:03:14.000000Z"},{"id":3,"name":"channel 3","created_at":"2020-07-10T06:03:14.000000Z","updated_at":"2020-07-10T06:03:14.000000Z"}]}

由于您在 promise 中设置了 channels 数据，您可以在模板中循环遍历它

注意：将channels: {}改为数组channels: []

<template>
    <div id="app">      
       <vue-chat :channels="channels"></vue-chat>
       <div v-for="channel in channles" :key="channel.id">
          <label>Channel Name</label>
          <input type="text" readonly :value="channel.name">
          <br>
          <label>Channel Name</label>
          <input type="text" readonly :value="channel.created_at">
       </div>
    </div>
</template>
