Question

仍然试图让我了解API和连接。

我正在尝试向Binance发出购买订单，但一直收到400条回复。我知道这对其他一些人来说是个问题，但我似乎无法怀疑我要去哪里。所以希望有人可以帮助我。

这只是POST的问题，所有GET请求都可以正常工作，因此对于签名和时间戳...或者至少我正在为我的帐户获取回复，所以我认为是这样。

第一个CURL仅用于serverTime，但是第二个CURL用于买卖订单。

这是我现在得到的答复...

“对象（[代码] => -1102 [msg] =>强制参数'side'不是已发送，为空/空或格式错误。）”

如果我手动在字符串中键入，它就可以正常工作，但是由于一个或另一个原因，当我传递$ qs时，会出现上述错误。我在屏幕上回显了$ qs并复制了该内容，而不是传递$ qs，当我放入新时间戳时它可以工作。我很沮丧...

“ symbol = TRXUSDC＆side = SELL＆type = LIMIT＆timeInForce = GTC＆quantity = 63000.00000000＆price = 0.02550000＆recvWindow = 1000000＆timestamp = 1550922237310”

有什么建议吗？

$header = array('X-MBX-APIKEY:' . KEY);
$url = BINANCE . 'api/v1/time';
$curl = curl_init();
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($curl, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1);
curl_setopt($curl, CURLOPT_TIMEOUT, 60);
curl_setopt($curl, CURLOPT_ENCODING, "");
curl_setopt($curl, CURLOPT_HTTPHEADER, $header);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_CUSTOMREQUEST, "GET");
curl_setopt($curl, CURLOPT_URL,$url);
$response = curl_exec($curl);

if (FALSE === $response){
        echo curl_error($curl), curl_errno($curl);
    }
$serverTime = json_decode($response);
curl_close($curl);

$url = BINANCE . "api/v3/order";
$signature = NULL;
$queryString = NULL;

$query = array(
    "symbol" => "TRXUSDC",
    "side" => "SELL",
    "type" => "LIMIT",
    "timeInForce" => "GTC", 
    "quantity" => number_format(63000.00000000,8,'.',''),
    "price" => number_format(0.02550000,8,'.',''), 
    "recvWindow" => 1000000,
    "timestamp" => $serverTime->serverTime);

$qs = htmlentities(http_build_query(array_unique($query)));
$query['signature'] = hash_hmac('SHA256', $qs, SECRET );
$curl = curl_init();
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($curl, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1);
curl_setopt($curl, CURLOPT_TIMEOUT, 60);
curl_setopt($curl, CURLOPT_ENCODING, "application/x-www-form-urlencoded");
curl_setopt($curl, CURLOPT_HTTPHEADER, $header);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($curl,CURLOPT_FAILONERROR,FALSE);
curl_setopt($curl, CURLOPT_VERBOSE, TRUE);
curl_setopt($curl, CURLOPT_POST, TRUE);
curl_setopt($curl, CURLOPT_POSTFIELDS,$qs);
curl_setopt($curl, CURLOPT_URL, $url);
$response = curl_exec($curl);
if (FALSE === $response){
    echo curl_error($curl).':'.curl_errno($curl);
}
$obj = json_decode($response);
curl_close($curl);

Answer 1

我尝试了这段代码，然后使用var_dump $ qs

symbol=BTCUSDT&amp;side=BUY&amp;...

所以我认为您必须删除放大器；

Answer 2

基于币安现货 api 文档：

建议使用5000以下的小recvWindow！最大不能超过 60,000！

所以编辑您的查询参数：

"symbol=TRXUSDC&side=SELL&type=LIMIT&timeInForce=GTC&quantity=63000.00000000&price=0.02550000&recvWindow=60000&timestamp=1550922237310"

您也可以检查您的其他查询参数和交换信息，您可以使用我们为您的交易品种提供的 https://api.binance.com/api/v3/exchangeInfo 获取这些信息：
