Groovy 中的 HTTP 身份验证？

Question

def http = new HTTPBuilder(url)
http.auth.basic username, password

def data = new URL(url)

def response = data.getText()

def relativePaths = new XmlParser().parseText(response)

relativePaths.each {page ->

    def link = page.content.@href.first()

    if(link.contains(".txt")){
        println link
    }

}

嗨，

当尝试运行它时，我得到一个 401。看起来像这里：

def response = data.getText()

它实际上不再经过身份验证（或根本没有）？在 Ruby 中，我会这样写：

(open(url, :http_basic_authentication => [username, password])
data = Nokogiri::XML(open(url, :http_basic_authentication => [username, password])))

在 Groovy 中会是什么样子？我使用httpbuilder 错了吗？提前非常感谢！

更新 1：

应用更改后：

def http = new HTTPBuilder(url)
http.auth.basic username, password

http.get(path: url, contentType: ContentType.TEXT) { resp, reader ->

    def relativePaths = new XmlParser().parse(reader)

    relativePaths.each { page ->

        def link = page.content.@href.first()

        if (link.contains(".txt")) {
            println link
        }
    }
}

我得到一个 406：

响应码：406；找到处理程序：org.codehaus.groovy.runtime.MethodClosure@5be46f9d 捕获：groovyx.net.http.HttpResponseException：不可接受 groovyx.net.http.HttpResponseException: 不可接受

还是不行。我将 contentType 更改为 XML 并将路径更改为实际路径，但收到错误消息：

只是为了比较，Ruby 脚本。也许httpbuilder 不是我想要的？我实际上只是想将其用于身份验证。

(open(url, :http_basic_authentication => [username, password])
data = Nokogiri::XML(open(url, :http_basic_authentication => [username, password])))

relativePaths = data.xpath("//content/@href")

relativePaths.each { |path| 
    if path.text.include? ".apk"
        puts "<URL>:<PORT>"+path.text
    end
}

Answer 1

你准备好接受手掌了吗？

您创建了一个HTTPBuilder 并且...从未使用过它。一切就绪……

def http = new HTTPBuilder(url)
http.auth.basic(username, password)

...但随后使用了新的URL 来检索数据：

def data = new URL(url)
def response = data.getText()

解决方案

HTTPBuilder 是这样使用的：

import groovyx.net.http.HTTPBuilder
import groovyx.net.http.ContentType

http.get(path : path, contentType : ContentType.TEXT) { resp, reader ->
    def relativePaths = new XmlParser().parse(reader)    
    ...
}

注意：我不确定get() 方法是否在后台运行。

更新的解决方案

将内容类型设置为 XML 会指示 HTTPBuilder 解析响应并将解析的文档作为第二个参数提供。该文档表示为Node。

http.get(path : path, contentType : ContentType.XML) { response, node ->
    def relativePaths = node    
    ...
}
