底层连接关闭的HTTP响应无效：发送时发生意外错误。 [英] Invalid HTTP response the underlying connection was closed: an unexpected error occurred on a send.

问题描述

我在Paypal集成中面临一些问题，

i发现此块的错误主要是调试时的最后一行代码。



< pre lang =C＃> ReceiverList sl = new ReceiverList（）;
sl.receiver.Add（rec）;
PayRequest req = new PayRequest（ new RequestEnvelope（ en_US）， PAY ，
cancelURl， USD，
sl， RETURNURL）;
req.reverseAllParallelPaymentsOnError = true ;
AdaptivePaymentsService service = new AdaptivePaymentsService（）;

PayResponse resp = null ;

resp = service.Pay（req）;

引用：

Service.Pay（REQ）;是抛出错误：无效的HTTP响应底层连接已关闭：发送时发生意外错误

我尝试过：



更新Paypal帐户等的API设置并更新nuget包的最新参考。

解决方案

您需要联系Paypal支持部门，了解他们的回复为何未按预期发布。

i facing some problem in Paypal integration,
i find error of this block mainly last line of code on debug time .

ReceiverList sl = new ReceiverList();
           sl.receiver.Add(rec);
           PayRequest req = new PayRequest(new RequestEnvelope("en_US"), "PAY",
                              cancelURl, "USD",
                              sl, returnURL);
           req.reverseAllParallelPaymentsOnError = true;
           AdaptivePaymentsService service = new AdaptivePaymentsService();
 
           PayResponse resp = null;
 
           resp = service.Pay(req);

Quote:

Service.Pay(req); is throw error: Invalid HTTP response The underlying connection was closed: An unexpected error occurred on a send

What I have tried:

Update API Setting on Paypal Account etc and Update latest reference by nuget package .

解决方案

You will need to contact Paypal support to find out why their response is not coming as you would expect.
