我可以使用cURL成功制作RESTful贴子：

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, \'https://api.mindbodyonline.com/public/v6/usertoken/issue\');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "{\\n    \\"Username\\": \\"Siteowner\\",\\n    \\"Password\\": \\"apitest1234\\"\\n}");

$headers = array();
$headers[] = \'Content-Type: application/json\';
$headers[] = \'Api-Key: {myapikey}\';
$headers[] = \'Siteid: 999999\';
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

$response = curl_exec($ch);
print_r($response);
if (curl_errno($ch)) {
    echo \'Error:\' . curl_error($ch);
}
curl_close($ch);

但是，使用wp_remote_post, 未能交付；Api密钥“；在标题中：

$headers = array();
$headers[] = \'Content-Type: application/json\';
$headers[] = \'Api-Key: {myapikey}\';
$headers[] = \'Siteid: 999999\';

$response = wp_remote_post( \'https://api.mindbodyonline.com/public/v6/usertoken/issue\', array(
    \'method\' => \'POST\',
    \'timeout\' => 45,
    \'redirection\' => 5,
    \'httpversion\' => \'1.0\',
    \'blocking\' => true,
    \'headers\' => $headers,
    \'body\' => array( \'Username\' => \'Siteowner\', \'Password\' => \'apitest1234\' ),
    \'cookies\' => array()
    )
);

if ( is_wp_error( $response ) ) {
   $error_message = $response->get_error_message();
   return "Something went wrong: " . $error_message;
} else {
   echo \'Response: <pre>\';
   print_r( $response );
   echo \'</pre>\';
   return;
}

有没有人发现我的语法中有明显的错误，或者对在哪里进行故障排除有什么建议？我看到了wp_remote_post 包装WP_Http 班

更新：

确认$headers 参数正在发送到Requests::request 如下所示：

Array
    (
        [0] => Content-Type: application/json
        [1] => Api-Key: {myapikey}
        [2] => Siteid: 99999
    )

检查到Requests::request 方法，似乎$transport （在此环境中）是以下对象：

Requests_Transport_cURL Object
(
    [headers] => 
    [response_data] => 
    [info] => 
    [version] => 468480
    [handle:protected] => Resource id #4
    [hooks:protected] => 
    [done_headers:protected] => 
    [stream_handle:protected] => 
    [response_bytes:protected] => 
    [response_byte_limit:protected] => 
)

在它里面request 方法，标头数组仍如上所述。

更新二：这很有趣。在里面Requests_Transport_cURLssetup_handle 方法，当CURLOPT_HTTPHEADER 已设置，$headers 如下所示：

Array
(
    [0] => 0: Content-Type: application/json
    [1] => 1: Api-Key: a3f5be6229744000b9bc25f603e80c45
    [2] => 2: Siteid: -99
    [3] => Connection: close
)

第385行：

385    curl_setopt($this->handle, CURLOPT_HTTPHEADER, $headers);

因此，我可能需要发送一个键值对哈希，而不是一个json字符串数组。

$headers = array();
$headers[\'Content-Type\'] = \'application/json\';
$headers[\'Api-Key\'] = \'{myapikey}\';
$headers[\'Siteid\'] = \'99999\';

\'body\' => "{\\n    \\"Username\\": \\"Siteowner\\",\\n    \\"Password\\": \\"apitest1234\\"\\n}"

\'body\' => json_encode(array( \'Username\' => \'Siteowner\', \'Password\' => \'apitest1234\' ))
