Question

我尝试编写PowerShell脚本并使用https://api.binance.com/api/v3/order/test REST链接对其进行测试，但它不起作用。我无法理解我应该将什么用作消息，什么是身体以及什么作为标题。看来这里一切都很清楚，当我看到一个linux示例时，我应该在输出中有相同的链接： https://github.com/binance-exchange/binance-official-api-docs/blob/master/rest-api.md 知道REST Post方法的人可以帮我弄清楚我应该在这里做些什么。

我的输出是：发布https://api.binance.com/api/v3/order/test?symbol=LTCBTC&side=BUY&type=LIMIT&timeInForce=GTC&quantity=1&price=0.1&recvWindow=5000&timestamp=1515586306172&signature=LxHZUfC5MiTUfMPyEtgaVShlV1j4ITo3QxvtPAzPkwQ=

非常感谢提前。

function getLinks(target, source, debpth) {

    $.each($(source).children('a'), function () {

        var item = $('<li></li>');

        if (debpth) {


            item.append($("<a href='" + $(this).attr('href') + "'><i class='fa fa-circle fa-fw' aria-hidden='true' style='font-size:6px;vertical-align:middle;padding-right:15px'></i>" + $(this).html() + "</a>"));
        }
        else {
            item.append($("<a href='" + $(this).attr('href') + "'>" + $(this).html() + "</a>"));
        }
        item.addClass('debpth' + (debpth ? debpth : 0).toString());
        target.append(item);   

        var nested = getNestedLists($(this).siblings('ul'), debpth ? debpth : 0);
        if (nested) {
            $.each(nested, function () {

                $(this).children('li').addClass('debpth' + (debpth ? debpth : 0).toString());

                target.append($(this).children('li'));
            });

        }

    });

}

Answer 1

问题在于这行代码：

$query->bindParam(":starting_limit", $starting_limit, PDO::PARAM_INT);

Binance希望HMAC SHA256以十六进制形式传输。用此替换上述内容，应解决问题。

$signature = [Convert]::ToBase64String($signature)

Answer 2

下面是我的工作代码。 APIKey和Secret来自Binance API文档的示例 https://github.com/binance-exchange/binance-official-api-docs/blob/master/rest-api.md#signed-endpoint-examples-for-post-apiv1order

$ Signature的结果应与Binance示例相同：c8db56825ae71d6d79447849e617115f4a920fa2acdcab2b053c4b2838bd6b71

如果您使用自己的APIKey和Secret，则应该可以使用

$APIKey = "vmPUZE6mv9SD5VNHk4HlWFsOr6aKE2zvsw0MuIgwCIPy6utIco14y7Ju91duEh8A"
$APISecret = "NhqPtmdSJYdKjVHjA7PZj4Mge3R5YNiP1e3UZjInClVN65XAbvqqM6A7H5fATj0j"

$TimeStamp = (Get-Date (Get-Date).ToUniversalTime() -UFormat %s).replace(',', '').replace('.', '').SubString(0,13)

$QueryString = "symbol=LTCBTC&side=BUY&type=LIMIT&timeInForce=GTC&quantity=1&price=0.1&recvWindow=5000&timestamp=1499827319559"

$hmacsha = New-Object System.Security.Cryptography.HMACSHA256
$hmacsha.key = [Text.Encoding]::ASCII.GetBytes($APISecret)
$signature = $hmacsha.ComputeHash([Text.Encoding]::ASCII.GetBytes($QueryString))
$signature = [System.BitConverter]::ToString($signature).Replace('-', '').ToLower()

$uri = "https://api.binance.com/api/v3/account?$QueryString&signature=$signature"

$headers = New-Object "System.Collections.Generic.Dictionary[[String],[String]]"
$headers.Add("X-MBX-APIKEY",$APIKey)   

try {

    Invoke-RestMethod -Uri $uri -Headers $headers -Method Get
}

Catch {

    $streamReader = [System.IO.StreamReader]::new($_.Exception.Response.GetResponseStream())
    $ErrResp = $streamReader.ReadToEnd() | ConvertFrom-Json
    $streamReader.Close()
    $ErrResp
}
