一、概述
最近在群里听到各种讨论okhttp的话题,可见okhttp的口碑相当好了。再加上Google貌似在6.0版本里面删除了HttpClient相关API,对于这个行为不做评价。为了更好的在应对网络访问,学习下okhttp还是蛮必要的,本篇博客首先介绍okhttp的简单使用,主要包含:
- 一般的get请求
- 一般的post请求
- 基于Http的文件上传
- 文件下载
- 加载图片
- 支持请求回调,直接返回对象、对象集合
- 支持session的保持
最后会对上述几个功能进行封装,完整的封装类的地址见:https://github.com/hongyangAndroid/okhttp-utils
使用前,对于Android Studio的用户,可以选择添加:
compile 'com.squareup.okhttp:okhttp:2.4.0'
- 1
- 1
或者Eclipse的用户,可以下载最新的jar okhttp he latest JAR,添加依赖就可以用了。
注意:okhttp内部依赖okio,别忘了同时导入okio:
gradle: compile 'com.squareup.okio:okio:1.5.0'
最新的jar地址:okio the latest JAR
二、使用教程
(一)Http Get
对了网络加载库,那么最常见的肯定就是http get请求了,比如获取一个网页的内容。
//创建okHttpClient对象
OkHttpClient mOkHttpClient = new OkHttpClient();
//创建一个Request
final Request request = new Request.Builder()
.url("https://github.com/hongyangAndroid")
.build();
//new call
Call call = mOkHttpClient.newCall(request);
//请求加入调度
call.enqueue(new Callback()
{
@Override
public void onFailure(Request request, IOException e)
{
}
@Override
public void onResponse(final Response response) throws IOException
{
//String htmlStr = response.body().string();
}
});

以上就是发送一个get请求的步骤,首先构造一个Request对象,参数最起码有个url,当然你可以通过Request.Builder设置更多的参数比如:
header
、method
等。然后通过request的对象去构造得到一个Call对象,类似于将你的请求封装成了任务,既然是任务,就会有
execute()
和cancel()
等方法。最后,我们希望以异步的方式去执行请求,所以我们调用的是call.enqueue,将call加入调度队列,然后等待任务执行完成,我们在Callback中即可得到结果。
看到这,你会发现,整体的写法还是比较长的,所以封装肯定是要做的,不然每个请求这么写,得累死。
ok,需要注意几点:
-
onResponse回调的参数是response,一般情况下,比如我们希望获得返回的字符串,可以通过
response.body().string()
获取;如果希望获得返回的二进制字节数组,则调用response.body().bytes()
;如果你想拿到返回的inputStream,则调用response.body().byteStream()
看到这,你可能会奇怪,竟然还能拿到返回的inputStream,看到这个最起码能意识到一点,这里支持大文件下载,有inputStream我们就可以通过IO的方式写文件。不过也说明一个问题,这个
onResponse
执行的线程并不是UI线程。的确是的,如果你希望操作控件,还是需要使用handler等,例如:@Override
public void onResponse(final Response response) throws IOException
{
final String res = response.body().string();
runOnUiThread(new Runnable()
{
@Override
public void run()
{
mTv.setText(res);
} });

- 我们这里是异步的方式去执行,当然也支持阻塞的方式,上面我们也说了Call有一个
execute()
方法,你也可以直接调用call.execute()
通过返回一个Response
。
(二) Http Post 携带参数
看来上面的简单的get请求,基本上整个的用法也就掌握了,比如post携带参数,也仅仅是Request的构造的不同。
Request request = buildMultipartFormRequest(
url, new File[]{file}, new String[]{fileKey}, null);
FormEncodingBuilder builder = new FormEncodingBuilder();
builder.add("username","张鸿洋");
Request request = new Request.Builder()
.url(url)
.post(builder.build())
.build();
mOkHttpClient.newCall(request).enqueue(new Callback(){});

- 7
- 8
- 9
- 10
大家都清楚,post的时候,参数是包含在请求体中的;所以我们通过FormEncodingBuilder。添加多个String键值对,然后去构造RequestBody,最后完成我们Request的构造。
后面的就和上面一样了。
(三)基于Http的文件上传
接下来我们在介绍一个可以构造RequestBody的Builder,叫做MultipartBuilder
。当我们需要做类似于表单上传的时候,就可以使用它来构造我们的requestBody。
File file = new File(Environment.getExternalStorageDirectory(), "balabala.mp4");
RequestBody fileBody = RequestBody.create(MediaType.parse("application/octet-stream"), file);
RequestBody requestBody = new MultipartBuilder()
.type(MultipartBuilder.FORM)
.addPart(Headers.of(
"Content-Disposition",
"form-data; name=\"username\""),
RequestBody.create(null, "张鸿洋"))
.addPart(Headers.of(
"Content-Disposition",
"form-data; name=\"mFile\";
filename=\"wjd.mp4\""), fileBody)
.build();
Request request = new Request.Builder()
.url("http://192.168.1.103:8080/okHttpServer/fileUpload")
.post(requestBody)
.build();
Call call = mOkHttpClient.newCall(request);
call.enqueue(new Callback()
{
//...
});

上述代码向服务器传递了一个键值对username:张鸿洋
和一个文件。我们通过MultipartBuilder的addPart方法可以添加键值对或者文件。
其实类似于我们拼接模拟浏览器行为的方式,如果你对这块不了解,可以参考:从原理角度解析Android (Java) http 文件上传
ok,对于我们最开始的目录还剩下图片下载,文件下载;这两个一个是通过回调的Response拿到byte[]然后decode成图片;文件下载,就是拿到inputStream做写文件操作,我们这里就不赘述了。
关于用法,也可以参考泡网OkHttp使用教程
接下来我们主要看如何封装上述的代码。
三、封装
由于按照上述的代码,写多个请求肯定包含大量的重复代码,所以我希望封装后的代码调用是这样的:
(一)使用
-
一般的get请求
OkHttpClientManager.getAsyn("https://www.baidu.com", new OkHttpClientManager.ResultCallback<String>()
{
@Override
public void onError(Request request, Exception e)
{
e.printStackTrace();
} @Override
public void onResponse(String u)
{
mTv.setText(u);//注意这里是UI线程
}
});- 1

- 3
- 4
- 5
- 6
- 7
- 8
- 9
- 10
- 11
- 12
- 13
- 14
对于一般的请求,我们希望给个url,然后CallBack里面直接操作控件。
-
文件上传且携带参数
我们希望提供一个方法,传入url,params,file,callback即可。
OkHttpClientManager.postAsyn("http://192.168.1.103:8080/okHttpServer/fileUpload",//
new OkHttpClientManager.ResultCallback<String>()
{
@Override
public void onError(Request request, IOException e)
{
e.printStackTrace();
} @Override
public void onResponse(String result)
{ }
},//
file,//
"mFile",//
new OkHttpClientManager.Param[]{
new OkHttpClientManager.Param("username", "zhy"),
new OkHttpClientManager.Param("password", "123")}
);- 1

- 14
- 15
- 16
- 17
- 18
- 19
- 20
- 21
- 22
键值对没什么说的,参数3为file,参数4为file对应的name,这个name不是文件的名字;
对应于http中的<input type="file" name="mFile" >
对应的是name后面的值,即mFile.
-
文件下载
对于文件下载,提供url,目标dir,callback即可。
OkHttpClientManager.downloadAsyn(
"http://192.168.1.103:8080/okHttpServer/files/messenger_01.png",
Environment.getExternalStorageDirectory().getAbsolutePath(),
new OkHttpClientManager.ResultCallback<String>()
{
@Override
public void onError(Request request, IOException e)
{ } @Override
public void onResponse(String response)
{
//文件下载成功,这里回调的reponse为文件的absolutePath
}
});- 1

-
展示图片
展示图片,我们希望提供一个url和一个imageview,如果下载成功,直接帮我们设置上即可。
OkHttpClientManager.displayImage(mImageView,
"http://images.csdn.net/20150817/1.jpg");- 1
- 2
- 1
- 2
内部会自动根据imageview的大小自动对图片进行合适的压缩。虽然,这里可能不适合一次性加载大量图片的场景,但是对于app中偶尔有几个图片的加载,还是可用的。
四、整合Gson
很多人提出项目中使用时,服务端返回的是Json字符串,希望客户端回调可以直接拿到对象,于是整合进入了Gson,完善该功能。
(一)直接回调对象
例如现在有个User实体类:
package com.zhy.utils.http.okhttp;
public class User {
public String username ;
public String password ;
public User() {
// TODO Auto-generated constructor stub
}
public User(String username, String password) {
this.username = username;
this.password = password;
}
@Override
public String toString()
{
return "User{" +
"username='" + username + '\'' +
", password='" + password + '\'' +
'}';
}
}

- 16
- 17
- 18
- 19
- 20
- 21
- 22
- 23
- 24
- 25
服务端返回:
{"username":"zhy","password":"123"}
- 1
- 1
客户端可以如下方式调用:
OkHttpClientManager.getAsyn("http://192.168.56.1:8080/okHttpServer/user!getUser",
new OkHttpClientManager.ResultCallback<User>()
{
@Override
public void onError(Request request, Exception e)
{
e.printStackTrace();
}
@Override
public void onResponse(User user)
{
mTv.setText(u.toString());//UI线程
}
});

- 6
- 7
- 8

- 10
- 11
- 12
- 13
- 14
- 15
- 1
- 2
- 3

- 5
- 6
- 7
- 8
- 9
- 10
- 11
- 12
- 13
- 14
- 15
我们传入泛型User,在onResponse里面直接回调User对象。
这里特别要注意的事,如果在json字符串->实体对象
过程中发生错误,程序不会崩溃,onError
方法会被回调。
注意:这里做了少许的更新,接口命名从StringCallback
修改为ResultCallback
。接口中的onFailure
方法修改为onError
。
(二) 回调对象集合
依然是上述的User类,服务端返回
[{"username":"zhy","password":"123"},{"username":"lmj","password":"12345"}]
- 1
- 1
则客户端可以如下调用:
OkHttpClientManager.getAsyn("http://192.168.56.1:8080/okHttpServer/user!getUsers",
new OkHttpClientManager.ResultCallback<List<User>>()
{
@Override
public void onError(Request request, Exception e)
{
e.printStackTrace();
}
@Override
public void onResponse(List<User> us)
{
Log.e("TAG", us.size() + "");
mTv.setText(us.get(1).toString());
}
});

唯一的区别,就是泛型变为List<User>
