我试图从一个名为zillow的网站获取API为我工作,但我对网络新东西是新手.他们尝试解释 here如何使用它,但它让我失去了所以我看了他们的论坛.有人在那里发布了一个“示例”,但我无法看
<html xml:lang="en" lang="en">

<body>
<h3><font face="Verdana, Arial, Helvetica, sans-serif">Get Property < # >Zestimates

<form method="post" action="/Real-Estate/Zestimate.php" name="zip_search">

<input id="street2" type="text" maxlength="50" size="50" value="" name="street"/></td>
<td> </td>
</tr>
<tr>
<td colspan="2"><font face="verdana, arial, sans-serif">City, State or ZipCode:</font>
<input id="citystatezip3" type="text" maxlength="50" size="20" value="" name="citystatezip"/></td>

<div align="center">
<input name="submit" type="submit" value="Get Zestimate">
</div>
</form>
你可以看到它只是一个简单的形式,自己发布了吗？但是当我点击它时,它会从API中提取数据并显示它,但我不知道如何.
我很乐意为您提供任何帮助,谢谢！
编辑：好的,这里.它只需要街道地址和城市/州,并返回格式化的值.错误检查遗漏：
