[英]Cannot retrieve data from Yelp API using jQuery.ajax()
我试图使用jQuery.ajax()
方法从Yelp API检索JSON数据,但它在控制台中不显示任何内容。
新的Yelp授权只需要将标头发送为:
"Authorization": "Bearer <apikey>"
以及带params的GET请求URL。 Postman正在显示结果,但我不能在我的API中使用它。 我的.ajax
代码在这里:
var myurl = "https://api.yelp.com/v3/businesses/search?term=by-chloe&location=boston";
$.ajax({
url: myurl,
headers: {
'Authorization': 'Bearer xxxxxxxxxxxxx',
},
method: 'GET',
dataType: 'json',
success: function(data) {
console.log('success: ' + data);
}
});
我需要对此进行任何更改,还是有问题?
我发现我测试你的脚本时的问题只是一个与CORS相关的问题; 通过将CORS-anywhere API附加到URL,我可以使用完全相同的代码命中您的端点。 尝试下面的代码(只需交换您的API密钥)

请记住交换API密钥以使上述示例有效。
CORS通常在服务器端启用; 这是一种防止未经授权的域连接到允许的数据以外的数据的方法; 我想如果你将服务器的IP地址列入白名单,你可能仍会遇到问题; 我已经构建了许多项目,这些项目都需要绕过CORS(使用CORS-Anywhere API,或者发出请求JSONP数据类型的请求)。 Cors-Anywhere通常是一个开源API,您可以在自己的服务器上实现它,或者继续使用heroku URL; 无论哪种方式,你都应该能够完成你的项目。
如果以上代码示例适合您,请告诉我们; 谢谢! - 宜兰
