当我们使用CURL来post数据的时候,需要设置post的数据
curl_setopt($c, CURLOPT_POSTFIELDS, $post_data);

假如这里的$data是

复制代码 代码如下:

$data = array(
'name'=>'scofield',
'time'=>'2012-2-3'
)

接下来,需要先将$data变成字符串
$post_data = http_build_query($data);
而采用 http_build_query 转换后再
curl_setopt($c, CURLOPT_POSTFIELDS, $post_data);

看起来没有什么问题。但在实际操作中,$post_data 并没有被post过去。于是,自己写了个转换的方法后就OK了。
复制代码 代码如下:

function getStr($array,$Separator='&') {
if (empty($array))
return;
if (!is_array($array)) {
return $array;
}
$returnStr = '';
foreach ($array as $key => $val) {
$temp = '';
if (is_array($val)) {
for ($i = 0; $i $returnStr .= $key . '[' . $i . ']' . '=' . $val[$i] . $Separator;
}
} else {
$returnStr.= $key . '=' . $val . $Separator;
}
}
$returnStr = substr(trim($returnStr), 0, -1);
return $returnStr;
}

感谢 黄斌-huangbin 童鞋的测试 http_build_query($data,"","&"); 即可,无需自己写方法解析了。

http_build_query 远程攻击者可以利用漏洞获得敏感内存信息。请大家谨慎使用
