新的谷歌自定义搜索API的结果 - PHP

因此，新的谷歌定制搜索已经推出了具有显示结果麻烦IM ...新的谷歌自定义搜索API的结果 - PHP

我使用PHP来返回JSON的结果和我得到一个无效的参数在每个错误...这里是我使用的是什么...

$url = "https://www.googleapis.com/customsearch/v1?key=MYKEY&cx=017576662512468239146:omuauf_lfve&q=test&callback=json"; 
$results = file_get_contents($url); 

foreach ($results->items as $r) 
{ 

}

这里的回调，当我去到URL在浏览器：

你应该试试这个：

$results = json_decode(file_get_contents($url));

为了能够正确地解码该服务的响应，你可以做到以下几点：

$json = file_get_contents($url); 

$start = 'json('; 
$end = ');'; 

$substr_start_pos = strpos($json, $start) + strlen($start); 
$substr_length = strlen($json) - $substr_start_pos - (strlen($json) - strrpos($json, $end)); 

$json = substr($json, $substr_start_pos, $substr_length); 

$results = json_decode($json);

这可能是一个有点混乱，但我这样做的原因如下：

你提供的样本响应有一个'json（'字符串在实际的JSON之前，和一个'）;'之后，它不能用PHP的json_decode解码。
简单替换并不好，因为实际的JSON也可能包含这些子字符串。

您通常想要测试您在将它传递给json_decode（）之前返回了非空字符串，以避免PHP警告。 – 2011-03-24 17:33:07

你是对的。而且，从file_get_contents获取来自URL的响应的方法要好得多。我只是展示了这个概念。 – 2011-03-24 17:35:48

你得到一个不好的请求的原因是因为我没有在URL中包含我的密钥，而是使用了“MYKEY”，这显然不是真正的密钥。我还将代码更改为[code] $ results = json_decode（file_get_contents（$ url））; [/ code]并获取相同的错误。 – tytyguy 2011-03-24 18:32:28

这是真的简单的PHP DECODE不会帮你，试试这个
$data = html_entity_decode($url); 我相信这将正常工作尝试以后变种转储到检查结果的日期。
