NoHttp是专门做Android网络请求与下载的框架.
NoHttp 源码及Demo https://github.com/Y0LANDA/NoHttp

前言

NoHttp是一个专门做Android网络相关的框架.
随着Android弃用HttpClient后, Google也发布了Volley, 在Android2.3之前使用HttpClient做请求，2.3之后使用URLConnection做请求, 看过Volley源码的同学应该知道, Volley虽然在2.3之后请求网络时使用URLConnection, 但是请求完成后解析过程还是用HttpClient的API，随着Android6.0中HttpClient的Api被删除，Volley也不能关联源码使用了, 此时NoHttp应运而生恰恰很好的解决了这个问题，下面为大家介绍一下NoHttp框架的使用。

NoHttp特性:

支持HTTP/HTTPS, 自动维持Cookie, 异步/同步请求, 大文件/多文件上传, 文件下载.
支持304缓存, 302/303重定向, 支持通过代理服务器访问地址(如: Google)
NoHttp是队列, 自动为请求排队, 可以取消指定请求, 可以取消队列所有请求, 亦可以停止队列.
支持请求String, Bitmap, JsonObject, 可自定义扩展请求类型
API使用简单, Request对象包涵参数, 文件, 请求头等; Response对象包涵响应内容, 响应头等信息.

使用Gradle构建时添加依赖:

一. 请求

1. 请求String数据

a. 添加参数, 上传文件, 添加请求头等

<code class="language-java hljs  has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><span class="hljs-comment" style="color: rgb(136, 0, 0); box-sizing: border-box;">// 创建请求队列, 正式项目中建议使用全局单例</span>
RequestQueue queue = NoHttp.newRequestQueue();
<span class="hljs-comment" style="color: rgb(136, 0, 0); box-sizing: border-box;">// 请求对象</span>
Request<String> request = NoHttp.createStringRequest(url, requestMethod);

<span class="hljs-comment" style="color: rgb(136, 0, 0); box-sizing: border-box;">//添加请求头</span>

b. 使用自定义请求-和NoHttp默认请求没有区别的哦

<code class="language-java hljs  has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">Request<JSONObject> mRequest = <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">new</span> FastJsonRequest(url, requestMethod);
queue.add(what, mRequest, responseListener);</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li></ul>

五. 下载文件

a. 发起下载请求

<code class="language-java hljs  has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><span class="hljs-comment" style="color: rgb(136, 0, 0); box-sizing: border-box;">//下载文件</span>
downloadRequest = NoHttp.createDownloadRequest(url, fielDir, fileName, <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">true</span>, <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">false</span>);
<span class="hljs-comment" style="color: rgb(136, 0, 0); box-sizing: border-box;">// what 区分下载</span>
<span class="hljs-comment" style="color: rgb(136, 0, 0); box-sizing: border-box;">// downloadRequest 下载请求对象</span>
<span class="hljs-comment" style="color: rgb(136, 0, 0); box-sizing: border-box;">// downloadListener 下载监听</span>
CallServer.getDownloadInstance().add(<span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">0</span>, downloadRequest, downloadListener);</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li><li style="box-sizing: border-box; padding: 0px 5px;">6</li></ul>

b. 暂停或者停止下载

<code class="language-java hljs  has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">downloadRequest.cancel();</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul>

c. 监听下载过程

<code class="language-java hljs  has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">private</span> DownloadListener downloadListener = <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">new</span> DownloadListener() {
