Realex HPP 请求-自定义字段

Question

我正在尝试向 realex 发送一个自定义字段，以便在成功响应时使用。有问题的字段是一个 json 数组。

[{"InvoiceId":7,"AmountPaid":180,"SucessfulPayment":false}]

我遇到的问题是响应数组被截断为 [{。我通过对数组进行 base 64 编码来实现这一点，但感觉它有点重，宁愿发送原始 json。我还担心字段长度可能会有字符限制，这会很快被吃掉。如果没有长度限制，我可能会使用 base 64。

更新

按要求编码。

JSON 传入请求对象的数组

[{"InvoiceId":7,"AmountPaid":180,"SucessfulPayment":false}]

realex 响应返回

[{

realex 响应中的失败代码：

if (Request.Form["INVOICE_ID"] != null)
   INVOICEID = Request.Form["INVOICE_ID"].ToString();
else
    StaticOps.AddErrorToLog("FORM.INVOICE_ID : ", "VALUE NULL", 
"RealexResponse");

很抱歉延迟回复您，没有看到您的回复通知。在 POST 中，HPP 不会接受字符串中那个点的引号和截断。

您能否尝试 url 在输出时对字符串进行编码并在响应返回时进行解码？ HPP 上自定义字段的最大长度为 255。或者您可以只 url 编码引号。希望这适合您的需求。如果没有请告诉我。

最佳，
