return返回没拿到值，async/await

Question

export async function getImgUrl(uuid) {
let path = await getImage(uuid)
return path
}

async function getImage(uuid){
let img= await getUuidImage(uuid)
return img;

}

<el-table-column label="参赛人照片" align="center">

<template slot-scope="scope">
  <img :src="getImageUrl(scope.row.headImg)" width="155px" height="100px"/>
</template>

</el-table-column>

getImageUrl (uuid) {

  return getImgUrl(uuid).then(res => {return res})

},

请问return 返回没拿到值

Answer 1

你return的是一个promise对象，当然没法绑定到src上。可以这样改：

getImageUrl (uuid) {

getImgUrl(uuid).then(res => {this.x=res;);

if (this.x===undefined){

return "";

}

return this.x;

}
