【问题描述】：

我正在尝试使用 4x6 生成 usps 标签，但我遇到了这个问题。谁能帮我生成 4x6Label。

我还尝试将版本从 DeliveryConfirmationV3 更改为 DeliveryConfirmationV4，但仍然没有生成 4x6Label。

我的 xml 请求传递为

https://secure.shippingapis.com/ShippingAPI.dll?API=DeliveryConfirmationV3&XML=<DeliveryConfirmationV3.0Request USERID="xxxxx" PASSWORD="xxxxxx">
<Option>1</Option>
<ImageParameters>
    <ImageParameter>4X6LABEL</ImageParameter>

</DeliveryConfirmationV3.0Request>

但我收到错误

<?xml version="1.0" encoding="utf-8"?>
<Error>
<Number>-2147221202</Number>
<Source>Common:XmlParse</Source>
<Description>The element 'ImageParameters' cannot contain child element 'ImageParameter' because the parent element's content model is text only.</Description>
 <HelpFile/>
 <HelpContext/>

最初它运行良好，但通过后

<ImageParameter>4X6LABEL</ImageParameter>

出现这个问题

目前我的代码是

   public Package GetDeliveryConfirmationLabel(Package package)
{
    string labeldate = package.ShipDate.ToShortDateString();
    if (package.ShipDate.ToShortDateString() == DateTime.Now.ToShortDateString()) 
        labeldate = "";

我已经更新了上面的代码，但我遇到了问题

【问题讨论】：

错误消息包含提示“内容模型仅是文本”，这意味着图像参数必须作为属性或作为标记的内容包含，例如 <imageparameters attributex="4X6LABEL"></imageparameters>或喜欢<imageparameters>4X6LABEL</imageparameters>。你有那个 Api 的 xsd 或文档，应该在哪里解释？
@dlatikay 我已经查看了usps.com/business/web-tools-apis/… 并添加了图像参数
现在我也看到了，你是对的，它在他们的样本中和你拥有的完全一样。看起来有些 API 版本冲突。
你为什么有API=DeliveryConfirmationV3？我对这个话题一点都不熟悉，但是当我搜索这个话题时，我发现了以下内容：usps.com/business/web-tools-apis/…，它只提到了API=eVS和API=eVSCertify。你能添加一个提到API=DeliveryConfirmationV3 的文档链接吗？
刚刚查看了您 8 月 21 日的评论。您可以参考API=PriorityMailIntl 的文档 - 所以不要指望它在不使用此 API 的情况下工作；)

【解决方案1】：

关于原问题：

4X6LABEL 不适用于 DeliveryConfirmationV3 API。要使用此选项，请选择支持它的 API。（你必须在PriorityMailIntl 和eVS 之间做出选择，这取决于你的需要）

您更新的代码：

无论出于何种原因，您都指定了<ImageType>TIF</ImageType>，但您似乎尝试将返回的数据用作PDF。尝试将它们保存并打开为 TIF 以测试您当前的结果，并尝试将请求的 ImageType 更改为 PDF 以获得您可能想要的结果。
