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"}

转为php发送curl OK

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"}

换成php 确只返回200 没有数据

<?php

$header= array('Authorization: token 97db4f9d77c23e99204668ef5dffd6177aa926a7');

$ch = curl_init();

curl_setopt($ch, CURLOPT_HTTPHEADER, $header);

curl_setopt($ch, CURLOPT_URL, 'https://iot.espressif.cn/v1/products/');

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

//curl_setopt($ch, CURLOPT_BINARYTRANSFER, true);

$response = curl_exec($ch);

echo $response;

print_r($response);

$json_parameter =$response;

$array = json_decode($json_parameter);

echo $array;

curl_close($ch);

?>
