所谓接口，就是提供一个url，只要你满足它要求的参数，就能得到你要的数据。比如你拿到一个接口，带上所需的参数，复制到地址栏同样能得到。不过最好用程序得到。file_get_contents也可以用，不过有局限性。所以我建议用curl。给你一个函数，挺好用的。
function request($url,$https=true,$method='GET',$data=null){
$ch = curl_init();//初始化，得到资源
curl_setopt($ch, CURLOPT_URL,$url); //请求数据的路径
curl_setopt($ch, CURLOPT_HEADER,false);//是否输出头
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); //不直接输出结果
//curl_setopt ($ch, CURLOPT_SAFE_UPLOAD, 0);//兼容php之后的版本
if($https){
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); //是否验证主机
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false); //是否进行证书验证
}
if($method=='POST'){
curl_setopt($ch, CURLOPT_POST, true); //POST传输
curl_setopt($ch, CURLOPT_POSTFIELDS, $data); //传输数据
}
$content_json = curl_exec($ch);
if ($content_json === false) {
return "网络请求出错: " . curl_error($ch);
}
curl_close($ch);
return $content_json;
}
php怎么改变数据接口的真实路径
?php
include("connection.php");
$perNumber=10; //每页显示的记录数
$page=$_GET['page']; //获得当前的页面值
$count=mysql_query("select count(*) from user"); //获得记录总数
$rs=mysql_fetch_array($count);
$totalNumber=$rs[0];
$totalPage=ceil($totalNumber/$perNumber); //计算出总页数
if (!isset($page)) {
$page=1;
} //如果没有值,则赋值1
$startCount=($page-1)*$perNumber; //分页开始,根据此方法计算出开始的记录
$result=mysql_query("select * from user limit $startCount,$perNumber"); //根据前面的计算出开始的记录和记录数
while ($row=mysql_fetch_array($result)) {
echo "user_id:".$row[0]."br";
echo "username:".$row[1]."br"; //显示数据库的内容
}
if ($page != 1) { //页数不等于1
?
a href="fenye.php?page=?php echo $page - 1;?"上一页/a !--显示上一页--
?php
}
for ($i=1;$i=$totalPage;$i++) { //循环显示出页面
?
a href="fenye.php?page=?php echo $i;?"?php echo $i ;?/a
?php
}
if ($page$totalPage) { //如果page小于总页数,显示下一页链接
?
用PHP写手机端APP数据接口和PC端数据接口有什么不一样？
都一样的 只是由于app不是浏览器不能正常使用cookie所以不支持session认证 在做app接口的时候一般都会使用自己定义的token来认证 其他的都是一致的
