问题描述
我花了一周的大部分时间试图弄清楚这件事,但仍然没有完成。我正在尝试使用 XML 方法在 MS Excel Power Query 中使用 Fedex 的 Track API。我已经完成了获得 TEST 凭据和 Productions 凭据的所有过程。
感谢@DiegoColantoni 对其他用户的惊人反馈,我设法想出了以下代码:
<?xml version="1.0" encoding="UTF-8"?>
<TrackRequest xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://fedex.com/ws/track/v19">

<Major>19</Major>
<Intermediate>0</Intermediate>
<Minor>0</Minor>
</Version>
<SelectionDetails>
<PackageIdentifier>
<Type>TRACKING_NUMBER_OR_DOORTAG</Type>
<Value>785459309647</Value>
</PackageIdentifier>
</SelectionDetails>
</TrackRequest>
我已经用 Postman 尝试过这段代码,并且得到了成功的响应,但是当我在 Power Query 中尝试它时,它不起作用。我在测试和生产环境中都收到此消息
>DataSource.Error: Web.Contents Failed to get contents from 'https://ws.fedex.com/xml' (500): Internal Server Error
Details:
DataSourceKind=Web
DataSourcePath=https://ws.fedex.com/xml
Url=https://ws.fedex.com/xml
code
由于它与 Postman 合作过,我认为这与请求本身有关,但我真的不明白出了什么问题。
这是完整的 Excel Power Query
let
url = "https://ws.fedex.com:443/xml",Body = Text.ToBinary("
<?xml version=""1.0"" encoding=""UTF-8""?>
<TrackRequest xmlns:xsi=""http://www.w3.org/2001/XMLSchema-instance"" xmlns:xsd=""http://www.w3.org/2001/XMLSchema"" xmlns=""http://fedex.com/ws/track/v19"">

"),Source = Web.Contents(url,[Headers=[Accept="image/gif,image/jpeg,image/pjpeg,text/plain,text/html,*/*",#"Content-Type"="text/xml"],Content = Body])
in
Source
解决方法
就请求正文而言,FedEx XML 普通 Web 服务非常具体:xml 开头的空行可能会导致 500 响应。
这就是 Excel Power Query 发生的情况,请查看实际 xml 前后的新行。删除它们应该可以解决问题。 IE。这应该有效:
let
url = "https://ws.fedex.com:443/xml",Body = Text.ToBinary("<?xml version=""1.0"" encoding=""UTF-8""?>
<TrackRequest xmlns:xsi=""http://www.w3.org/2001/XMLSchema-instance"" xmlns:xsd=""http://www.w3.org/2001/XMLSchema"" xmlns=""http://fedex.com/ws/track/v19"">
