例1

代码如下

复制代码

$data = array("name" => "Hagrid", "age" => "36");
$data_string = json_encode($data);

$ch = curl_init('http://api.local/rest/users');
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json',
'Content-Length: ' . strlen($data_string))
);

$result = curl_exec($ch);

例2

代码如下

复制代码

function http_post_data($url, $data_string) {

$ch = curl_init();
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json; charset=utf-8',
'Content-Length: ' . strlen($data_string))
);
ob_start();
curl_exec($ch);
$return_content = ob_get_contents();
ob_end_clean();

$return_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
return array($return_code, $return_content);
}

$url = "http://xx.xx.cn";
$data = json_encode(array('a'=>1, 'b'=>2));

list($return_code, $return_content) = http_post_data($url, $data);

例3

代码如下

复制代码

$data=' {
"button":[
{
"type":"click",
"name":"今日歌曲",
"key":"V1001_TODAY_MUSIC"
},
{
"type":"click",
"name":"歌手简介",
"key":"V1001_TODAY_SINGER"
},
{
"name":"菜单",
"sub_button":[
{
"type":"click",
"name":"hello word",
"key":"V1001_HELLO_WORLD"
},
{
"type":"click",
"name":"赞一下我们",
"key":"V1001_GOOD"
}]
}]
}';

$ch = curl_init($urlcon); //请求的URL地址
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);//$data JSON类型字符串
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json', 'Content-Length: ' . strlen($data)));
$data = curl_exec($ch);
print_r($data);//创建成功返回：{"errcode":0,"errmsg":"ok"}

小结，我们发现最核心的一句代码就是Content-Type: application/json;这个是文件格式类型了。
