我在哪里可以下载包 jar for org.apache.http?

http://hc.apache.org/downloads.cgi
更新了一个新的链接

你可以加

org.apache.http

, 使用下面的代码

app:Build gradle

dependencies {

 compile 'org.apache.httpcomponents:httpclient:4.5'

}

在回购中 Maven 有样品可以添加依赖 maven, sbt, gradle 等等。

https://mvnrepository.com/arti ... .4.11
即 Maven 例如，您只需创建一个项目，例如

mvn archetype:generate -DarchetypeGroupId=org.apache.maven.archetypes -DarchetypeArtifactId=maven-archetype-quickstart -DarchetypeVersion=1.4

然后看看 pom.xml, 然后在元素中的图书馆 dependencies xml:

<dependency>

<groupid>org.apache.httpcomponents</groupid>

<artifactid>httpcore</artifactid>

<version>4.4.11</version>

</dependency>

为了 sbt 做一些类似的事情

sbt new scala/hello-world.g8

然后编辑 build.sbt, 添加库

libraryDependencies += "org.apache.httpcomponents" % "httpcore" % "4.4.11"

你需要 httpclient.jar 和 httpcore.jar. 您可以在此处下载它们。
