• 使用文档链接获取API密钥

//设置endpoint和你的访问密钥endpoint = 'latest' access_key = 'API_KEY';
//通过“latest”端点获取最近的汇率：

$.ajax({
       url: 'https://api.exchangeratesapi.io/v1/' + endpoint + '?access_key=' + access_key,
       dataType: 'jsonp',
       success: function(json) {

           // exchange rata data is stored in json.rates
           alert(json.rates.GBP);
   
           // base currency is stored in json.base
           alert(json.base);
   
           // timestamp can be accessed in json.timestamp 
           alert(json.timestamp);
   
       } });
