无法使用 php 获取 coinmarket 的 api
[英]can't get the api of coinmarket work with php
问题描述
I wanted to make a priceChecker for the Cardano coin and it works with the general api.
我想为卡尔达诺硬币制作一个价格检查器，它适用于通用 api。 https://api.coinmarketcap.com/v1/ticker/ . https://api.coinmarketcap.com/v1/ticker/ 。
But i want to use this api because i don't need the info of the other coins.但我想使用这个 api，因为我不需要其他硬币的信息。 https://api.coinmarketcap.com/v1/ticker/cardano . https://api.coinmarketcap.com/v1/ticker/cardano 。
the code i used for the first one:我用于第一个的代码：
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<title id="title"></title>
</head>
<table>
<tr>
<th>Cardano</th>
</tr>
<tr>
<td id="cardano"></td>
</tr>
</table>
<script>
$.get("https://api.coinmarketcap.com/v1/ticker/", function(data, status) {
for (var i = 0; i < data.length - 1; i++) {
if (data[i].id == "cardano") {
$("#title").html(data[i].price_usd);
$("#cardano").html(data[i].price_usd);
}
}
});
</script>
</body>
</html>
It seems really easy to change to the other api but i just can't get it work.更改为其他 api 似乎很容易，但我无法使其正常工作。
My code for the second one:我的第二个代码：
<script>
$.get("https://api.coinmarketcap.com/v1/ticker/cardano", function(data, status) {
$("#title").html(data[0].price_usd);
$("#cardano").html(data[0].price_usd);
});
</script>

$.get("https://api.coinmarketcap.com/v1/ticker/cardano/", function(data, status) {
$("#title").html(data[0].price_usd);
$("#cardano").html(data[0].price_usd);
});
works for me, just finishing the url with / .对我有用，只需用/完成网址。 I think without the final slash doesn't work due to some redirect rules in the web server.我认为由于 Web 服务器中的某些重定向规则，没有最后一个斜杠是行不通的。
Bytheway, the first example would be more optimised with a break inside the if condition:顺便说一句，第一个示例将在 if 条件中使用中断进行更优化：
$.get("https://api.coinmarketcap.com/v1/ticker/", function(data, status) {
for (var i = 0; i < data.length - 1; i++) {
if (data[i].id == "cardano") {
$("#title").html(data[i].price_usd);
$("#cardano").html(data[i].price_usd);
break;
}
}
});
this way the for stops when the cardano id is found.这样当找到 cardano id 时 for 就会停止。
