这是一个片段,我使用从指定2个变量的URL收集JSON中的一些数据:
<?php
function soldipubblici() {
$curl_parameters = array(
'codicecomparto' => "PRO",
'codiceente' => "011120674",
);
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL,"http://soldipubblici.gov.it/it/ricerca");
curl_setopt($ch,CURLOPT_POST,true);
curl_setopt($ch,CURLOPT_POSTFIELDS,http_build_query( $curl_parameters ));
curl_setopt($ch,CURLOPT_HTTPHEADER,array (
"Content-Type: application/x-www-form-urlencoded; charset=UTF-8",
"Accept: application/json",
"X-Requested-With: XMLHttpRequest",
));
$output=curl_exec($ch);
curl_close($ch);
}
echo soldipubblici();
?>
您可以注意到变量是手动设置的。所以我提出了一个包含2个选项的简单网页。输入标记仅用于测试POST数据。
<!DOCTYPE HTML>
<html>
<head>
<title>Test</title>
<script src="//cdnjs.cloudflare.com/ajax/libs/jquery/2.1.3/jquery.min.js" type="text/javascript"></script>
</head>
<body>
<form>
<label>Seleziona l'ente</label>
<select name="data" id="data">
<option value="PRO - 011142764">COMUNE DI AGLIE'</option>
<option value="PRO - 011120674">COMUNE DI AGRATE CONTURBIA</option>
</select>
<input type="text" name="textfield" id="textfield" />
</form>
<script>
$('#data').change(function() {
$.post("richiesta.php", { value: this.value });
$('#textfield').val(this.value);
});
</script>
</body>
</html>
这是richiesta.php
,它接收有关更改事件的POST数据(我跟着this线程):
<?php
list($comparto, $ente) = explode("-", $_POST['value'], 2);
echo "comparto: $comparto, ente: $ente";
?>
请求正常,在更改事件时我成功获取POST值:
因为它有效,我现在可以放在richiesta.php我的&#34;真实&#34;函数有两个变量,这次不是手动但是从POST请求中检索值:
<?php
function soldipubblici() {
list($comparto, $ente) = explode("-", $_POST['value'], 2);
$curl_parameters = array(
'codicecomparto' => $comparto,
'codiceente' => $ente,
);
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL,"http://soldipubblici.gov.it/it/ricerca");
curl_setopt($ch,CURLOPT_POST,true);
curl_setopt($ch,CURLOPT_POSTFIELDS,http_build_query( $curl_parameters ));
curl_setopt($ch,CURLOPT_HTTPHEADER,array (
"Content-Type: application/x-www-form-urlencoded; charset=UTF-8",
"Accept: application/json",
"X-Requested-With: XMLHttpRequest",
));
$output=curl_exec($ch);
curl_close($ch);
}
echo soldipubblici();
?>
不幸的是它不起作用:(
我在Firebug中得到一个空的响应...如果在相同的片段中我手动设置2个变量,如果有效......看起来他们没有从list
函数正确传递。

选项中的-
周围有空格,您可能需要删除它们。
$curl_parameters = array(
'codicecomparto' => trim($comparto),
'codiceente' => trim($ente),
);
