没有得到 json 输出形式 axios

Question

我正在使用 axios 从维基百科检索数据 Api。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);

我在控制台记录时能够得到输出。内容如下：在本例中，我正在搜索 Jon Snow 这个名字。如何访问 json?

Answer 1

如果 res.data 是您的 http 请求的 JSON 响应，您可以使用 JSON.parse() 函数

将其解析为 JSON

var linkJSON = JSON.parse(res.data)

这将为您提供 linkJSON 对象中的 json 数据。

Answer 2

在 json 的开头有 '/**/(' 和结尾的 ')' 字符，这些字符已按子字符串切割。解析后。

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...")
 });
