我正在使用 ktor 和使用 cors 构建一个简单的 REST API,但是当我发送一个没有标头数据的简单 get 请求时,服务器工作正常,但是如果我希望客户端说 key:1,服务器没有正确响应我,它说问题是
Failed to load http://127.0.0.1:8080/test: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'null' is therefore not allowed access. The response had HTTP status code 403.
所以这是我的 ktor 代码
install(ContentNegotiation) {
gson {
}
}
install(ForwardedHeaderSupport)
install(DefaultHeaders)
install(CORS)
{
method(HttpMethod.Options)
method(HttpMethod.Get)
method(HttpMethod.Post)
method(HttpMethod.Put)
method(HttpMethod.Delete)
method(HttpMethod.Patch)
header(HttpHeaders.AccessControlAllowHeaders)
header(HttpHeaders.ContentType)
header(HttpHeaders.AccessControlAllowOrigin)
allowCredentials = true
anyHost()
maxAge = Duration.ofDays(1)
}
...
get("test"){
val a = call.request.headers["key"]
println(a)
call.respond(Product(name = a))
}
我的javascript代码看起来像这样......
fetch('http://shop-ix.uz:8080/test', {
headers: {
"key": "1"
})
.then(response => response.json())
.then(json => {
console.log(json);
})
请帮我
