Android Gradle Apache HttpClient 不存在?

问题描述

我正在尝试将 IntelliJ 项目转换为 Android Studio 的 Gradle 系统，但我在使用 Apache HttpClient 时遇到错误?我是否遗漏了什么，我得到的错误如下:

I am trying to convert an IntelliJ project to the Gradle system of Android Studio but I am running into errors with Apache HttpClient? Am I missing something, the errors I am getting are as follows:

Error:(10, 30) error: package org.apache.http.client does not exist
Error:(11, 30) error: package org.apache.http.client does not exist

我的 build.gradle 文件具有以下依赖项:

My build.gradle file has the following dependencies:

dependencies {
    compile 'com.google.android.gms:play-services:+'
    compile 'org.apache.httpcomponents:httpclient:4.2.6'
    compile 'org.apache.httpcomponents:httpmime:4.2.6'
    compile files('libs/core.jar')
}

似乎很多人都遇到了类似的问题，但 SO 或 Google 都没有解决方案，所以我希望这个问题能帮助未来的搜索者.

It seems a lot of people are getting a similar problem but neither SO or Google have a solution so I am hoping this question will help future searchers.

推荐答案

我建议您用新的 HttpURLConnection 替换已弃用的 apache HttpClient.

I suggest you replace the deprecated apache HttpClient with the new HttpURLConnection.

这是一个更简洁的解决方案，它很容易迁移，而且通常坚持最新的 SDK 更改比尝试破解/修补/解决方法更好:您通常会在以后后悔:)

That's a cleaner solution, it's quite easy to migrate, and generally it's better to stick to the latest SDK changes than trying to hack/patch/workaround: you usually regret it later :)

第一步

HttpGet httpGet = new HttpGet(url);

变成:

URL urlObj = new URL(url);

第 2 步

HttpClient httpClient = new DefaultHttpClient();
HttpContext localContext = new BasicHttpContext();
HttpResponse response = httpClient.execute(httpGet, localContext);
InputStream is = response.getEntity().getContent();

变成:

HttpURLConnection urlConnection = (HttpURLConnection) urlObj.openConnection();
InputStream is = urlConnection.getInputStream();

第 2 步之二

int status = response.getStatusLine().getStatusCode();

变成:

int status = urlConnection.getResponseCode();
