更新JDK 8 Update 121

由于Oracle在其下载链接中插入了一些md5hash，因此不能自动组装命令行下载链接。

所以我修改了一些讨厌的bash命令行来获得最新的jdk下载链接，下载并通过rpm直接安装。 对于所有感兴趣的人:

wget -q http://www.oracle.com/technetwork/java/javase/downloads/index.html -O ./index.html && grep -Eoi ']+>' index.html | grep -Eoi '/technetwork/java/javase/downloads/jdk8-downloads-[0-9]+.html' | (head -n 1) | awk '{print "http://www.oracle.com"$1}' | xargs wget --no-cookies --header "Cookie: gpw_e24=xxx; oraclelicense=accept-securebackup-cookie;" -O index.html -q && grep -Eoi '"filepath":"[^"]+jdk-8u[0-9]+-linux-x64.rpm"' index.html | grep -Eoi 'http:[^"]+' | xargs wget --no-cookies --header "Cookie: gpw_e24=xxx; oraclelicense=accept-securebackup-cookie;" -q -O ./jdk8.rpm && sudo rpm -i ./jdk8.rpm

粗体部分应该换成你喜欢的包装

你应该试试:

wget \
        --no-cookies \
        --header "Cookie: oraclelicense=accept-securebackup-cookie" \
        http://download.oracle.com/otn-pub/java/jdk/8u172-b11/a58eab1ec242421181065cdc37240b08/jdk-8u172-linux-x64.tar.gz \
        -O java.tar.gz

Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F;oraclelicense = accept-securebackup-cookie " " http://download.oracle.com/otn-pub/java/jdk/8u161-b12/2f38c3b165be4555a1fa6e98c45e0808/jdk-8u161-linux-x64.rpm?AuthParam=1516282527_40effcfefd78d78bce12c0a4030a1b05 "

oracle-java-download是GitHub上的一个项目，允许您为JDK 8和JDK 9创建下载链接，您可以使用这些链接进行进一步处理，例如在自动构建或部署过程中。

它需要Linux、Docker和JDK >= 8才能运行。

我没有为每一个新的Java版本都使用一个新的链接或更改现有的脚本，而是寻找一种更通用的方法来自动下载所需的Java包，然后通过yum localinstall ${JAVA_ENVIRONMENT}-${JAVA_VERSION}-linux-x64.rpm进行安装。

我使用了一种类似于手动/用户操作的简单方法来查找包并下载它。我也非常确定，通过使用其他工具(如egrep、awk等)，人们会找到一种更优雅的方式来完成它。，所以这里留一个例子:

#!/bin/bash

### Proxy settings
# If there is a company proxy 

PROXY="my.proxy.local:8080"
PROXY_TYPE="--proxy-ntlm" # or leave empty with ""
USER="user"
PASS='pass'

### Find out the links to JRE and JDK 
# To do so, got to the page http://www.oracle.com/technetwork/java/javase/downloads/

BASE_URL="technetwork/java/javase/downloads"

# Put the whole page into a single string/line

BASE_URL_OUTPUT="$(curl -s -k ${PROXY_TYPE} -x "http://${USER}:${PASS}@${PROXY}" -L0 http://www.oracle.com/${BASE_URL}/)"

# Define the environments to download 

JAVA_ENVIRONMENTS=("JRE" "JDK") # ! yet "SERVER-JRE"

for JAVA_ENVIRONMENT in "${JAVA_ENVIRONMENTS[@]}"
do

echo
echo "JAVA_ENVIRONMENT="$JAVA_ENVIRONMENT
echo

for (( JAVA_BASE_VERSION = 8; JAVA_BASE_VERSION <= 10; JAVA_BASE_VERSION += 2 ))  
do

echo "JAVA_BASE_VERSION="$JAVA_BASE_VERSION

### "Read the page"
# and follow the links for the package interested in 

DOWNLOAD_SITE="$(echo $BASE_URL_OUTPUT | grep -m 1 -io "${JAVA_ENVIRONMENT}${JAVA_BASE_VERSION}-downloads-[0-9]*.html" -- | tail -1)"
echo "DOWNLOAD_SITE="$DOWNLOAD_SITE

### Gather the necessary download links
# To do so, following the link to the download site
# reading and accept the license 
# 
# ... the greedy regular expression is to address the different syntax of the links
# and already prepared for OR .gz files 

DOWNLOAD_LINK_OUTPUT="$(curl -s -k ${PROXY_TYPE} -x "http://${USER}:${PASS}@${PROXY}" -L -j -H "Cookie: oraclelicense=accept-securebackup-cookie" http://www.oracle.com/${BASE_URL}/${DOWNLOAD_SITE} |  grep -io "filepath.*${JAVA_ENVIRONMENT}-[${JAVA_BASE_VERSION}].*linux[-_]x64[._].*\(rpm\)" -- | cut -d '"' -f 3 | tail -1)"

# and echo out the link

echo "DOWNLOAD_LINK_OUTPUT="$DOWNLOAD_LINK_OUTPUT

done

done

由于下载链接现已可用，您可以进一步使用wget或curl。

下面是如何获得命令自己。 这适用于任何版本:

Access packages page here: https://www.oracle.com/java/technologies/javase-jdk11-downloads.html Click the download link for your desired package Check the box indicating that you have "reviewed and accept..." Right-click & Copy the link address from the button Paste into a text editor and then copy everything AFTER 'nexturl=', beginning with 'https://' Update the download URL in this command and you should be good to go: wget --no-check-certificate -c --header "Cookie: oraclelicense=accept-securebackup-cookie" https://download.oracle.com/otn/java/jdk/11.0.6+8/90eb79fb590d45c8971362673c5ab495/jdk-11.0.6_linux-x64_bin.tar.gz

为了进一步解释wget，——no-check-certificate应该足够清楚，但是通过使用浏览器中的Developer Tools Network选项卡可以发现头部内容(对于任何调用)。开发人员工具功能强大，非常值得花时间学习。 享受。
