Bitmex API(PHP)，取消一项订单无效 [英] Bitmex API (PHP), cancel one order doesn't work

问题描述

我正在使用PHP.当我尝试通过API取消一个有效订单时，出现错误:

I'm using PHP. When I try to cancel one active order via API i got error:

"error" => array:2 [▼
   "message" => "orderIDs or clOrdIDs must be sent."
   "name" => "ValidationError"
]

我将orderID作为数组(这是我的lib方法):

I put orderID as array (this is my lib method):

public function cancelOrder($orderID) {
   $symbol = self::SYMBOL;
   $data['method'] = "DELETE";
   $data['function'] = "order";
   $data['params'] = array(
      "orderID" => $orderID, // ['r5ff364da-4243-8ee3-7853-6fb0f9f7e44d']
   );
   return $this->authQuery($data);
}

我做错了什么? https://www.bitmex.com/api/explorer/#!/Order/Order_cancel

推荐答案

晚些时候参加聚会，但是我想我会在最终弄清这一点后回答，并想象这对尝试在PHP中使用Bitmex API的其他人很有用(特别是如果您在kstka的github上使用bitmex-api-php包装器).

Late to the party, but thought i would answer as I finally figured this out, and imagine it would be useful for anyone else trying to use Bitmex API with PHP (Especially if you're using bitmex-api-php wrapper on kstka's github).

首先，将订单ID号放入一个数组中，即使它只是一个:

First, put the order Id number into an array, even if it's just one:

public function cancelOrder($orderId) {
    $orderArr = array($orderId);
    $symbol = self::SYMBOL;
    $data['method'] = "DELETE";
    $data['function'] = "order";
    $data['params'] = array(
      'orderID' => $orderArr,
    );
    return $this->authQuery($data);
}

然后，您需要确保您的参数是json编码的，但仅适用于DELETE

Then you need to make sure your params are json encoded, but only for DELETE

if($method == "GET" || $method == "POST" || $method == "PUT") {
    $params = http_build_query($data['params']);
} elseif($method == "DELETE") {
    $params = json_encode($data['params']);
}

然后，最重要的是，您需要确保CURL标头是json编码的:

and then, most importantly, you need to ensure the CURL headers are json encoded:

if($data['method'] == "DELETE") {
    curl_setopt($this->ch, CURLOPT_CUSTOMREQUEST, "DELETE");
    curl_setopt($this->ch, CURLOPT_POSTFIELDS, $post);
    $headers[] = 'X-HTTP-Method-Override: DELETE';
    $headers[] = 'Content-Type: application/json';
 }

你应该开怀大笑.这花了我一辈子的时间！

You should be away laughing. This took my forever to figure out!
