php中使用curl两个例子

第一个例子：

调用一个天气预告的接口

$data = 'theCityName=石家庄';

$cUrl = curl_init();

curl_setopt($cUrl, CURLOPT_URL, "http://www.webxml.com.cn/webservices/weatherwebservice.asmx/getWeatherbyCityName");

curl_setopt($cUrl, CURLOPT_HEADER, 0);

curl_setopt($cUrl, CURLOPT_RETURNTRANSFER, 1);

curl_setopt($cUrl, CURLOPT_POST, 1);

curl_setopt($cUrl, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);

curl_setopt($cUrl, CURLOPT_POSTFIELDS, $data);

curl_setopt($cUrl, CURLOPT_HTTPHEADER, array("application/x-www-form-urlencoded; charset=utf-8", "Content-length: ".strlen($data)));





$output = curl_exec($cUrl);



if(!curl_errno($cUrl)) {

    echo $output;

}else{

    echo "Curl error:  ".curl_error($cUrl);

}

//echo str_replace("百度", "^_^", $output);



curl_close($cUrl);

第二个例子：

模拟登录一个站点并保存某个页面

$data = 'name=admin&password=123456';

$cUrl = curl_init();

curl_setopt($cUrl, CURLOPT_URL, "http://www.***.com/a/login.html");

curl_setopt($cUrl, CURLOPT_RETURNTRANSFER, 1);

date_default_timezone_set('PRC');



curl_setopt($cUrl, CURLOPT_COOKIESESSION, TRUE);

curl_setopt($cUrl, CURLOPT_COOKIEFILE, "cookiefile");

curl_setopt($cUrl, CURLOPT_COOKIEJAR, "cookiefile");

curl_setopt($cUrl, CURLOPT_COOKIE, session_name()."=".session_id());

curl_setopt($cUrl, CURLOPT_HEADER, 0);

curl_setopt($cUrl, CURLOPT_FOLLOWLOCATION, 1);

curl_setopt($cUrl, CURLOPT_POST, 1);

//curl_setopt($cUrl, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);

curl_setopt($cUrl, CURLOPT_POSTFIELDS, $data);

curl_setopt($cUrl, CURLOPT_HTTPHEADER, array("application/x-www-form-urlencoded; charset=utf-8", "Content-length: ".strlen($data)));

curl_exec($cUrl);



curl_setopt($cUrl, CURLOPT_URL, "http://www.***.com/a/analysisIndex.html");//要保存的页面

curl_setopt($cUrl, CURLOPT_POST, 0);

curl_setopt($cUrl, CURLOPT_HTTPHEADER, array("Content-type: text/xml"));

$output = curl_exec($cUrl);

curl_close($cUrl);

echo $output;
