使用JavaScript的Exchange API [英] Exchange API using javascript

问题描述

我正在使用JavaScript在此网站上使用API​​

您不能从JS代码调用API，因为 api.mybitx.com 会阻止跨域请求。

您有几种解决方案：

1. 创建自己的服务器端API方法。
   从您的JS代码中调用此方法。
   使用api.mybitx.com API system.net.webrequest（v = vs.110）.aspx rel = nofollow noreferrer> WebRequest 或 RestSharp 。




2. 如果只想在JS代码上执行此操作，则需要使用 EasyXDM 库。

第一种解决方案更简单，更正确。

I'm using javascript to use the API on this site https://www.luno.com/en/api and I don't understand why I am not receiving any data. When if I just enter this url: https://api.mybitx.com/api/1/ticker?pair=XBTZAR I do receive data in the broswer.

var xmlhttp = new XMLHttpRequest();
xmlhttp.onreadystatechange = function() {
  if (this.readyState == 4 && this.status == 200) {
    var myObj = JSON.parse(this.responseText);
    document.getElementById("luno").innerHTML = myObj.bid;
  }
};
xmlhttp.open("GET", "https://api.mybitx.com/api/1/ticker?pair=XBTZAR", true);
xmlhttp.send();

Why is it not returning anything?

解决方案

You have a trouble with CORS requests.

You can see similar error on your developer console:

You can't call API from JS code because api.mybitx.com blocks cross domain request.

You have a several solutions:

1. Create own server side API method. Call this method from your JS code. Inside the API method call api.mybitx.com API using WebRequest or RestSharp.

2. If you want to do it only on JS code, then you need to use EasyXDM library.

For me the first solution is more simpler and more correct.
