Kotlin 使用VertX提供favicon.ico和其他静态文件
我正试着给你送一份便笺和一些字体Kotlin 使用VertX提供favicon.ico和其他静态文件,kotlin,vert.x,Kotlin,Vert.x,我正试着给你送一份便笺和一些字体 object Lion : AbstractVerticle() { @JvmStatic @Throws(IOException::class) fun main(args: Array<String>) { val vertx = Vertx.vertx() val router = Router.router(vertx) router.route().handler(CorsHandler
object Lion : AbstractVerticle() {
@JvmStatic
@Throws(IOException::class)
fun main(args: Array<String>) {
val vertx = Vertx.vertx()
val router = Router.router(vertx)
router.route().handler(CorsHandler.create("*")
.allowedMethod(HttpMethod.GET)
.allowedMethod(HttpMethod.POST)
.allowedMethod(HttpMethod.OPTIONS)
.allowedHeader("X-PINGARUNER")
.allowedHeader("Content-Type"))
// some json GET / POST routes here
router.route().handler(FaviconHandler.create());
router.route().handler(StaticHandler.create())
vertx.createHttpServer().requestHandler { router.accept(it) }.listen(9090)
}
删除FaviconHandler
和普通html
,js
和css
文件可以正常使用,但字体无法正常使用
Failed to decode downloaded font: http://localhost:9090/fonts/glyphicons-halflings-regular.woff
/#/tcr:1 OTS parsing error: incorrect file size in WOFF header
当我直接转到该字体url时,浏览器试图将该字体作为常规文件下载
这似乎是一个潜在的解决方案,但我看到的不是我的favicon,只是一个16x16的正方形,其中有扭曲的线条,字体仍在尝试下载,并且仍在浏览器控制台中给出错误
router.route("/favicon.ico").handler {
it.response().putHeader("Content-Type", "image/x-icon").sendFile("webroot/favicon.ico")
}
router.route("/fonts/glyphicons-halflings-regular.woff").handler {
it.response().putHeader("Content-Type", "application/font-woff").sendFile("webroot/fonts/glyphicons-halflings-regular.woff")
}
总之,如何使StaticHandler
使用正确的mimetype正确地提供.woff
和.ico
文件,而不让它下载这些文件
解决方案:
我遇到的第一个问题是,出于某种原因,maven shade没有将所有字体文件复制到jar中
在构建时显式复制字体文件并禁用字体的资源筛选似乎已经解决了字体问题
<build>
<sourceDirectory>${basedir}/src/main/java</sourceDirectory>
<resources>
<resource>
<directory>${basedir}/src/main/resources</directory>
<filtering>true</filtering>
</resource>
<resource>
<directory>${basedir}/src/main/resources/fonts</directory>
<filtering>false</filtering>
</resource>
</resources>
Favicon可能正在缓存,仍在调查中,Favicon目前还没有那么关键
router.route("/favicon.ico").handler(FaviconHandler.create("favicon.ico"))
Favicon.ico: 只需将您的
favicon.ico
文件直接向上移动到resources
文件夹中:
/src/main/resources/favicon.ico
或者,将您的FaviconHandler
更改为传入路径和文件名:
router.route().handler(FaviconHandler.create(FaviconHandler.create("webroot/favicon.ico")))
您的代码假定FaviconHandler
也尊重StaticHandler
中设置的webroot
,但它不尊重。这纯粹是StaticHandler
的属性,因此FaviconHandler
在resources/
中查找资源,除非指定相对路径。当找不到该资源时,null
将崩溃
如果查看FaviconHandlerImpl
的单元测试,您将看到它而不是webroot
WOFF文件: 至于你的字体文件,你在错误的地方寻找问题。它与MIME类型无关 更有可能的是,您在事故中损坏了WOFF文件。这可能发生在您使用GIT提交它们时,GIT认为它们是文本文件,因此它破坏了行尾,从而损坏了它们。或者你使用了Maven过滤器插件,它也做了同样的事情,腐蚀了他们。或者你通过FTP上传/下载了文本文件,同样的问题

请参阅其他关于此的帖子:您没有指定favicon路径,因此Vertx尝试查找默认路径:
if (path == null) {
icon = new Icon(Utils.readResourceToBuffer("favicon.ico"));
}
您的favicon位于resources/webroot/favicon.ico
,但Vertex会在resources/favicon.ico
