PHP&解析JSON响应 [英] PHP & Parsing a JSON response
问题描述
我正在尝试通过REST来使用Web服务.
I'm trying to play with a web service via REST.
我终于得到了想要的结果(或者至少我认为是)，但是不知道该怎么做.响应格式为JSON.我尝试通过json_decode()输出以将其作为数组获取，然后可以对其进行处理.
I finally am getting the results I want (or at least I think I am), but am unaware what to do with it. The response format is JSON.. I try outputting it via json_decode() to get it as an array, then I could do something with it.
您可以看到我在回显我正在卷曲的网址时得到了某物"作为响应
You can see that I am getting "something" as a response as I am echoing the url that I am CURL'ing
我知道这是一个教育问题，但这是我的第一时间，因此我们将不胜感激.再次，我的最终目标是明显地以可读格式输出数据.
I know this is a matter of education, but this is my first jaunt at this, so any help is appreciated. Again, my end goal is to obviously output the data in a readable format.
<?php
if(isset($_GET['word']))
{
$result= get_response_json($_GET['word']);
} else {$result = "";}
function get_response_json($word)
{
$postURL = "http://rhymebrain.com/talk?function=getRhymes&word=".urlencode($word);
echo $postURL;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $postURL);
curl_setopt($ch, CURLOPT_HEADER, false);
//curl_setopt($ch, CURLOPT_POST, true);
$result = curl_exec($ch);
curl_close($ch);
return $result;
}
?>
<html>
<title>Test Rhyme</title>
<body>
<form action="<?=$_SERVER['PHP_SELF'];?>" method="get">
<input type="input" name="word" />
<input type="submit" value="Submit" />
</form>
<div id="results">
<?php
print_r(json_decode($result, true));
?>
</div>
</body>
</html>
推荐答案
在此处检查: http://php.net/manual/zh/function.curl-exec.php .我看到的一件值得注意的事情是:
Check here: http://php.net/manual/en/function.curl-exec.php. The one noteworthy thing I saw was this:
成功返回TRUE，失败返回FALSE.但是，如果设置了CURLOPT_RETURNTRANSFER选项，则成功时将返回结果，失败时将返回FALSE.
Returns TRUE on success or FALSE on failure. However, if the CURLOPT_RETURNTRANSFER option is set, it will return the result on success, FALSE on failure.
请注意，如果您搜索"curl_get(")，就是一个很好的例子.
Note that there is a great example if you search for "curl_get(".
