json - 没有从 axios 获得 json 输出

问题描述

我正在使用 axios 从 Wikipedia Api 检索数据。这是我写的代码。

let axiosData = function(){
let searchString = $('#searchString').val();
console.log(searchString);
let Url = "https://en.wikipedia.org/w/api.php?action=opensearch&search="+ searchString + 
"&origin=*&callback=";
axios.get(Url)
 .then(function(res){
     var linkLists = res.data;
     console.log(linkLists);
 })
 .catch(function(){
     console.log("Error")
 });
return false;
}

$('form').submit(axiosData);

当我控制台记录它时，我能够得到一个输出。以下是：在这种情况下，我正在搜索 Jon Snow 的名字。如何访问json？

解决方案

在 json 的开头有 '/**/(' 和结尾的 ')' 字符，它们被子字符串剪切。解析之后。

let Url = "https://en.wikipedia.org/w/api.php?action=opensearch&format=json&search=jon%20snow&origin=*&callback=";
axios.get(Url)
.then(function(res){
 console.log(res);
 var linkLists = JSON.parse(res.data.substring(5, res.data.length-1));
 console.log(linkLists)
 })
 .catch(function(){
   console.log("Error...")
 });
