[英]PHP & Parsing a JSON response
I'm trying to play with a web service via REST. 我正在尝试通过REST来使用Web服务。
I finally am getting the results I want (or at least I think I am), but am unaware what to do with it. 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。 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. 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。
You can see that I am getting "something" as a response as I am echoing the url that I am CURL'ing 您会看到我在回显我正在卷曲的URL时得到了“响应”
I know this is a matter of education, but this is my first jaunt at this, so any help is appreciated. 我知道这是受教育的问题,但这是我对此的初衷,因此我们将不胜感激。 Again, my end goal is to obviously output the data in a readable format. 再次,我的最终目标是显然以可读格式输出数据。
<?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>
Check here: http://php.net/manual/en/function.curl-exec.php . 在这里检查: http : //php.net/manual/en/function.curl-exec.php 。 The one noteworthy thing I saw was this: 我看到的一件值得注意的事情是:
Returns TRUE on success or FALSE on failure. 成功返回TRUE,失败返回FALSE。 However, if the CURLOPT_RETURNTRANSFER option is set, it will return the result on success, FALSE on failure. 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。
Note that there is a great example if you search for "curl_get(". 请注意,如果您搜索“ curl_get(”,则是一个很好的例子。
Here's an example: 这是一个例子:
$json = '[
{
"ID": "1001",
"Phone": "5555555555"
}
]';
$jsonArray = json_decode($json);
foreach($jsonArray as $value){
$id = $value->ID;
$phone = $value->Phone;
}
Here's a simplified way to do it without cURL 这是一种无需cURL的简化方法
function get_response_json($word)
{
$postURL = "http://rhymebrain.com/talk?function=getRhymes&word=".urlencode($word);
$json = file_get_contents($postURL);
return $json;
}
