我正在尝试使用cURL发送带有POST请求的JSON文本。JSON文本为:
{"channel":"My channel","username":"我的用户名","text":"My text"}
我使用的是这个代码:
<?php
$data = array(
'username' => 'My username',
'channel' => 'My channel'
'text' => 'My text',
);
$data_json = json_encode($data);
$curl = curl_init('my-url');
curl_setopt($curl, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($curl, CURLOPT_POSTFIELDS, $data_json);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($curl, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json',
'Content-Length: ' . strlen($data_json))
);
$result = curl_exec($curl);
echo $result ;
?>
代码有效,但我想在JSON文本中添加一个"附件"数组,如下所示:
所以我试着把它添加到我的$data数组中:
'attachments' => '[{"text":"Line 1", "color":"#000000"}, {"text":"Line 2", "color":"#ffffff"}]',
但不起作用,帖子被发送了,但我的"附件"被忽略了。。。我还尝试直接从Linux终端发送POST,代码是:
POST https://myurl.com
payload={"channel": "My channel", "username": "My username", "text": "My text", "attachments": [{"text":"Line 1","color":"#000000"},{"text":"Line 2","color":"#ffffff"}]}
它正在发挥作用。。。我只是不明白为什么它使用手动POST而不使用php/ccurl。。。
谢谢你的回答

您正在执行双重json_encode。
首先,比较这两个:
$json1 = json_encode([
'firstname' => 'Jon',
'lastname' => 'Doe',
'hp' => [
'cc' => '+1',
'number' => '12345678'
]
);
//You should get
//{"firstname":"Jon","lastname":"Doe","hp":{"cc":"+1","number":"12345678"}}
这个:
$json2 = json_encode([
'firstname' => 'Jon',
'lastname' => 'Doe',
'hp' => "['cc' => '+1', 'number' => '12345678']"
]);
//You should get
//{"firstname":"Jon","lastname":"Doe","hp":"['cc' => '+1', 'number' => '12345678']"}
你看到问题了吗?您将attachments
密钥设置为json编码的字符串,因此当它被发送到目标服务器时,它将被视为字符串'[{"text":"Line 1", "color":"#000000"}, {"text":"Line 2", "color":"#ffffff"}]'
,而不是预期的文本颜色对数组。这里没有什么花哨的,这纯粹是一个粗心的错误:)
因此,为了解决这个问题,不要在attachments
密钥中发送json编码的字符串,而是使用以下内容:
$data = array(
'username' => 'TriiNoxYs',
'channel' => 'My channel'
'text' => 'My text',
'attachments' => array(
array(
"text" => "Line 1",
"color" => "#000000",
),
array(
"text" => "Line 2",
"color" => "#ffffff"
)
)
);
