vb.net - 远程服务器返回错误：(400) 错误请求。同时通过qbxml在线连接到QB

Question

我与在线 QB 的连接工作正常。它也适用于在线将客户添加到 QB。当我通过检查时，它会给出错误的请求错误。

下面是我的 qbxml。

string post = @"<?xml version=""1.0"" encoding=""utf-8"" ?>
            <?qbxml version=""10.0""?>
            <QBXML>

有人可以指导吗？

Answer 1

As the qbxml version needs to be 6.0 (even though the IDN Unified On-Screen Reference shows 7.0)
I needed to include the onError="continueOnError" attribute.
Setting the WebRequestObject.ContentLength property is required.
Content Type needs to be "application/x-qbxml"
And finally I received many "The remote server returned an error: (400) Bad Request." exceptions which were not helpful at all but in the end I was able to trace them to something wrong with the xml. So if you get this exception look to your xml as the source of the problem.

所以，最后我改变了我的xml如下。

    string post = @"<?xml version=""1.0"" encoding=""UTF-8""?>
<?qbxml version=""6.0""?>
<QBXML>
