php通过curl post和get发送json数据实例 curl命令转为php源码

curl命令对应着php源码

12. curl命令工具测试 正常返回

获取状态：
curl -X GET -H "Content-Type:application/json" -H "Authorization: token 4e56266f2502936e0378ea6a985dc74a5bec4280" http://iot.espressif.cn/v1/datastreams/plug-status/datapoint/ 
返回{"status": 200, "datapoint": null}


设置状态：
curl  -H "Authorization: token 6bcb3cdb69b07370f5ad73e7a856409802fdd735" -d "{\"datapoint\":{\"x\":1}}" http://iot.espressif.cn/v1/datastreams/plug-status/datapoint/?deliver_to_device=true
返回{"status": 404, "nonce": 333984364, "message": "remote device is disconnect"}

参考：

利用php curl发送json数据与curl post其它数据是一样的，下面我来给大家总结几个关于curl post发送json数据实例，希望能加深各位对curl post json数据的理解吧。 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。

例1

$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

 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

$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"}
