ASP.Net C#MVC5 Razor查看XML站点地图

Question

我的控制器动作看起来像这样.

public ActionResult Sitemap()
        {
            Response.ContentType = "application/xml";
            return View();
        }

我的视图Sitemap.cshtml看起来像这样.

@{Layout = null;}<?xml version='1.0' encoding='UTF-8' ?>
<urlset xmlns="http://www.google.com/schemas/sitemap/0.84"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemalocation="http://www.google.com/schemas/sitemap/0.84
http://www.google.com/schemas/sitemap/0.84/sitemap.xsd">
    <url>
        <loc>https://www.mywebsitename.com/home</loc>
        <lastmod>2006-12-12</lastmod>
        <changefreq>weekly</changefreq>
        <priority>1.00</priority>
    </url>
</urlset>

我在浏览器中获取ERROR页面(http://localhost:50831/Sitemap)

This page contains the following errors:

error on line 2 at column 6: XML declaration allowed only at the start of the document
Below is a rendering of the page up to the first error.

我已从View(Sitemap.cshtml)中删除了所有空格.但仍然是错误

我甚至尝试了这个并反转了如下所示的顺序,但仍然是错误.

<?xml version='1.0' encoding='UTF-8' ?>
@{    Layout = null;}
<urlset xmlns="http://www.google.com/schemas/sitemap/0.84"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemalocation="http://www.google.com/schemas/sitemap/0.84
http://www.google.com/schemas/sitemap/0.84/sitemap.xsd">
    <url>
        <loc>https://www.mywebsitename.com/home</loc>
        <lastmod>2006-12-12</lastmod>
        <changefreq>weekly</changefreq>
        <priority>1.00</priority>
    </url>
</urlset>

它似乎是在标头之前发送空的空格或行,导致上述错误.布局为空,视图以xml标记开始,并从中获取空白空间.

页面源输出

----EMPTY LINE----
        <?xml version='1.0' encoding='UTF-8' ?>
        <urlset xmlns="http://www.google.com/schemas/sitemap/0.84"
                xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                xsi:schemalocation="http://www.google.com/schemas/sitemap/0.84
        http://www.google.com/schemas/sitemap/0.84/sitemap.xsd">
            <url>
                <loc>https://www.mywebsitename.com/home</loc>
                <lastmod>2006-12-12</lastmod>
                <changefreq>weekly</changefreq>
                <priority>1.00</priority>
            </url>
        </urlset>

我无法理解为什么？任何的想法？

我检查了以下但仍无法找到答案

Answer 1

我通过在Response.Write中添加XML标记来解决问题

@{   
    Response.Write("<?xml version='1.0' encoding='UTF-8' ?>");
    Layout = null;
    }
<urlset xmlns="http://www.google.com/schemas/sitemap/0.84"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemalocation="http://www.google.com/schemas/sitemap/0.84
http://www.google.com/schemas/sitemap/0.84/sitemap.xsd">
    <url>
        <loc>https://www.mywebsitename.com/home</loc>
        <lastmod>2006-12-12</lastmod>
        <changefreq>weekly</changefreq>
        <priority>1.00</priority>
    </url>
</urlset>
