[英]Web.config transforms add tree
I want to add the following to the web config on release: 我想在发布时将以下内容添加到Web配置中:
<system.webServer>
<httpProtocol>
<customHeaders>
<add name="Strict-Transport-Security" value="max-age=16070400; includeSubDomains" xdt:Transform="Insert" />
</customHeaders>
</httpProtocol>
</system.webServer>
There aren't any custom headers in the default web config so I get an error when I publish: No element in the source document matches '/configuration/system.webServer/httpProtocol/customHeaders'
. 默认的Web配置中没有任何自定义标头,因此发布时会出现错误:
No element in the source document matches '/configuration/system.webServer/httpProtocol/customHeaders'
。
I can fix it my just adding the empty elements to the web.config like so: 我可以修复它,只需将空元素添加到web.config中,如下所示:
<httpProtocol>
<customHeaders>
</customHeaders>
</httpProtocol>
However, it doesn't feel like the correct way. 但是,这感觉不正确 。
Is there a more correct way to build the element tree on the transform? 有没有更正确的方法在转换上构建元素树?
Adding the empty <customHeaders>
node to the web.config works because the transform you have is to insert the <add .../>
node, not the <customHeaders>
node. 将空的
<customHeaders>
节点添加到web.config中是<customHeaders>
,因为您进行的转换是插入<add .../>
节点,而不是<customHeaders>
节点。 It can only insert where it matches to that point. 它只能插入与该点匹配的位置。
To insert the tree of nodes, move the xdt:Transform="Insert"
up a little in the XML. 要插入节点树,请在XML中向上移动
xdt:Transform="Insert"
。 If you start with a web.config of: 如果从以下Web.config开始:
<?xml version="1.0">
<configuration>
<system.webServer>
<httpProtocol />
</system.webServer>
</configuration>
and transform it with: 并将其转换为:
<?xml version="1.0">
<configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">
<system.webServer>
<httpProtocol>
<customHeaders xdt:Transform="Insert">
<add name="Strict-Transport-Security" value="max-age=16070400; includeSubDomains" />
</customHeaders>
</httpProtocol>
</system.webServer>
</configuration>
You'll end up with: 您最终将得到:
<?xml version="1.0">
<configuration>
<system.webServer>
<httpProtocol>
<customHeaders>
<add name="Strict-Transport-Security" value="max-age=16070400; includeSubDomains" />
</customHeaders>
</httpProtocol>
</system.webServer>
</configuration>
