kotlin stream.assequence（）现在都需要stream.iterator（）。
我正在使用java.net.httpclient在响应类型httpresponse＆lt; stream＆gt;中发出简单的获取请求。但是，即使Kotlin.Streams具有 sequence（）方法，我现在必须先在调用assequence（）之前先将流转换为迭代器。为什么这样？
val client = HttpClient.newHttpClient()
val request = HttpRequest.newBuilder().let { builder ->
builder.uri(URI("http://localhost:8000/response.txt"))
builder.setHeader("Content-Type", "application/json")
builder.GET()
builder.build()
}
val resp: HttpResponse<Stream<String>> = client.send(request, HttpResponse.BodyHandlers.ofLines())
//used to be resp.body().asSequence().map{
resp.body().iterator().asSequence().map {
println("${it.toString()}")
}
I am using java.net.HttpClient to issue a simple GET request where the response is of type HttpResponse<Stream>. However, even though Kotlin.streams has an asSequence() method, I now have to first convert the stream to an iterator before calling asSequence(). Why is this the case?
val client = HttpClient.newHttpClient()
val request = HttpRequest.newBuilder().let { builder ->
builder.uri(URI("http://localhost:8000/response.txt"))
builder.setHeader("Content-Type", "application/json")
builder.GET()
builder.build()
}
val resp: HttpResponse<Stream<String>> = client.send(request, HttpResponse.BodyHandlers.ofLines())
//used to be resp.body().asSequence().map{
resp.body().iterator().asSequence().map {
println("${it.toString()}")
}

在build.gradle.kts中，我引用了错误的JDK版本。当我导入
org.jetbrains.kotlin：kotlin-stdlib-jdk8作为依赖项时，问题解决了。In the build.gradle.kts I was referencing the wrong version of the jdk. The problem resolved when I imported
org.jetbrains.kotlin:kotlin-stdlib-jdk8as a dependency.
