Qiniu Resource Storage SDK for Android

@qiniu on weibo Software License Build Status Latest Stable Version

演示代码

https://github.com/qiniudemo/qiniu-lab-android

安装

运行环境

Qiniu SDK 版本 最低 Android版本 依赖库版本
7.2.x Android 2.3+ okhttp 3+
7.1.x Android 2.3+ okhttp 2.6+
7.0.8,7.0.9 Android 2.2+ android-async-http 1.4.9
7.0.7 Android 2.2+ android-async-http 1.4.8

直接安装

将sdk jar文件 复制到项目中去,jar包下载地址 , 下载对应的jar包,以及搜索下载对应的依赖库

happy-dns下载地址

通过maven

  • 如果在Adroid Studio中使用,添加dependencies compile 'com.qiniu:qiniu-android-sdk:7.2.+' 或在项目中添加maven依赖
  • 如果是eclipse, 也可以直接添加依赖来处理。

使用方法

UploadManager 可以创建一次,一直使用。

import com.qiniu.android.storage.UploadManager;
...
    String token = "从服务端SDK获取";
    UploadManager uploadManager = new UploadManager();
    uploadManager.put("Hello, World!".getBytes(), "hello", token,
    new UpCompletionHandler() {
        @Override
        public void complete(String key, ResponseInfo info, JSONObject response) {
            Log.i("qiniu", info);
        }
    }, null);
...

测试

$ ./gradlew connectedAndroidTest

常见问题

1).有关Android Studio以及Eclipse安装运行Android Demo步骤,这里以Android Studio为实例: 1.修改 build.gradle 双击打开您的工程目录下的build.gradle,在dependencies中添加一条依赖compile 'com.qiniu:qiniu-android-sdk:7.2.+',如下所示:

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.1.1'
    compile 'com.qiniu:qiniu-android-sdk:7.2.+'
}

当然也可以将jar包下载到本地导入到项目中

2.添加相关权限,在 app/src/main 目录中的 AndroidManifest.xml 中增加如下 uses-permission 声明


3.布局,在res/layout/activity_main.xml添加相应的上传的按钮以及相关控件,以下以一个简单的布局为例:



    <Button />

效果如下: 这里写图片描述

4.逻辑代码, 为按钮添加上传事件,这里以上传一个byte数组为例,另外,上传的数据可以是文件路径或者文件,以下给出具体的代码:

package com.dxy.cloud.myapplication;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
import com.qiniu.android.http.ResponseInfo;
import com.qiniu.android.storage.UpCompletionHandler;
import com.qiniu.android.storage.UploadManager;
import com.qiniu.android.storage.UploadOptions;
import org.json.JSONObject;

public class MainActivity extends Activity implements View.OnClickListener {

    //指定upToken, 强烈建议从服务端提供get请求获取, 这里为了掩饰直接指定key
    public static String uptoken = "xxxxx:xxxxx:xxxxx";
    private Button btnUpload;
    private TextView textView;
    private UploadManager uploadManager;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        textView = (TextView) findViewById(R.id.textView);
        btnUpload = (Button) findViewById(R.id.button);
        btnUpload.setOnClickListener(this);
        //new一个uploadManager类
        uploadManager = new UploadManager();

    }

    @Override
    public void onClick(View v) {
        Log.i("qiniutest", "starting......");
        byte[] data=new byte[]{ 0, 1, 2, 3};
        //设置上传后文件的key
        String upkey = "uploadtest.txt";
        uploadManager.put(data, upkey, uptoken, new UpCompletionHandler() {
            public void complete(String key, ResponseInfo rinfo, JSONObject response) {
                btnUpload.setVisibility(View.INVISIBLE);
                String s = key + ", " + rinfo + ", " + response;
                Log.i("qiniutest", s);
                textView.setTextSize(10);
                String o = textView.getText() + "rnrn";
                //显示上传后文件的url
                textView.setText(o + s + "n" + "http://xm540.com1.z0.glb.clouddn.com/" + key);
            }
        }, new UploadOptions(null, "test-type", true, null, null));

    }
}

运行的效果图如下: 这里写图片描述

2).有关断点续传,暂停上传,设置自定义变量的用法,这里以一个简单的Demo给出下实现的方法,这里的Demo主要实现从相册选择一张图片上传来说明。

可以参考放GitHub(Android Studio)上的源码: https://github.com/clouddxy/AndroidDemo 这里直接给出MainActivity中的代码:

3).关于从服务器获取Token上传: Android SDK为客户端SDK,没有包含token生成实现,为了安全,token都建议通过网络从服务端获取,具体生成代码可以参考"java/python/php/ruby/go"等服务端sdk, 其实也比较简单,可以使用okhttp发送一个简单的get请求就可以了,这里以使用SyncHttpClient为例来说明:

package com.example.androidupload;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.Menu;
import android.view.MenuItem;
import com.google.gson.JsonElement;
import com.google.gson.JsonParser;
import com.loopj.android.http.SyncHttpClient;
import com.loopj.android.http.TextHttpResponseHandler;
import com.qiniu.android.storage.UpCompletionHandler;
import com.qiniu.android.storage.UpProgressHandler;
import com.qiniu.android.storage.UploadManager;
import com.qiniu.android.storage.UploadOptions;
import com.qiniu.android.utils.UrlSafeBase64;
import org.apache.http.Header;
import org.json.JSONObject;
import java.io.File;
import java.util.UUID;

public class MainActivity extends Activity {

    private UploadManager uploadManager;
    private final String tag = "MainActivity";

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        //设置本地上传的文件的路径
        String path ="/storage/emulated/0/Download/DSC_0770.JPG";
        String aaa = UrlSafeBase64.encodeToString(path);
        File file =new File(path);
    }

    private void upload(final String localPath,final String key)
    {
        Thread thread = new Thread()
        {
            @Override
            public void run() {
                super.run();
                SyncHttpClient client = new SyncHttpClient();
                //获取服务端的token的url
                String url = "http://xxxx/xxxx/xxx";
                client.get(url, new TextHttpResponseHandler() {
                    @Override
                    public void onFailure(int i, Header[] headers, String s, Throwable throwable) {
                    }
                    @Override
                    public void onSuccess(int i, Header[] headers, String s) {
                        Log.i(tag,"请求七牛token:"+s);
                        JsonParser jsonParser = new JsonParser();
                        JsonElement jsonElement =jsonParser.parse(s);
                        String token = jsonElement.getAsJsonObject().get("uptoken").toString();
                        Log.i(tag,"七牛开始上传"+localPath+"n"+key+"n"+token);
                        if(uploadManager==null)
                        {
                            uploadManager = new UploadManager();
                        }
                        UploadOptions uploadOptions = new UploadOptions(null, null, false,
                                new UpProgressHandler() {
                                    @Override
                                    public void progress(String key, double percent) {
                                        Log.i(tag,"a 七牛上传progress:"+percent+"n"+key);
                                    }
                                }, null);

                        //调用uploadManager上传
                        uploadManager.put(localPath, key, token, new UpCompletionHandler() {
                            @Override
                            public void complete(String key, com.qiniu.android.http.ResponseInfo info, JSONObject response) {
                                Log.i(tag, "a 七牛上传complete:"+key + ",rn " + info + ",rn " + response);
                            }
                        },uploadOptions);
                    }
                });
            }
        };
        thread.start();
    }
}

4).关于for循环上传: 可以参考demo:

package com.dxy.cloud.myapplication;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
import com.qiniu.android.http.ResponseInfo;
import com.qiniu.android.storage.UpCompletionHandler;
import com.qiniu.android.storage.UploadManager;
import com.qiniu.android.storage.UploadOptions;
import org.json.JSONObject;

public class MainActivity extends Activity implements View.OnClickListener {

    //指定upToken, 强烈建议从服务端提供get请求获取, 这里为了掩饰直接指定key
    public static String uptoken = "xxxxxxxxx:xxxxxxx:xxxxxxxxxx";
    private Button btnUpload;
    private TextView textView;
    private UploadManager uploadManager;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        textView = (TextView) findViewById(R.id.textView);
        btnUpload = (Button) findViewById(R.id.button);
        btnUpload.setOnClickListener(this);
        //new一个uploadManager类
        uploadManager = new UploadManager();
    }

    @Override
    public void onClick(View v) {
        Log.i("qiniutest", "starting......");
        byte[] data=new byte[]{ 0, 1, 2, 3, 3, 4, 5, 6,0, 1, 2, 3, 4, 5, 6,0, 1, 2, 3, 4, 5, 6,0, 1, 2, 3, 4, 5, 6,0, 1, 2, 3, 4, 5, 6,0, 1, 2, 3,};

       for(int i=0;i&lt;data.length;i++){
            String expectKey =UUID.randomUUID().toString();
            uploadManager.put(data, expectKey, uptoken, new UpCompletionHandler() {
                public void complete(String k, ResponseInfo rinfo, JSONObject response) {
                    String s = k + &quot;, &quot;+ rinfo + &quot;, &quot; + response;
                    Log.i(&quot;qiniutest&quot;, s);
                    String key = getKey(k, response);

            }, new UploadOptions(null, &quot;test-type&quot;, true, null, null));
        }
    }
}

5).常见的返回的状态码: 使用七牛 Android sdk 的时候, 如果使用方式不正确,会返回一些对应的错误码。 具体可以参考源码: https://github.com/qiniu/android-sdk/blob/c4cd1437aa1f2a0d68122e46b83580facdf1b74a/library/src/main/java/com/qiniu/android/http/ResponseInfo.java

public static final int ZeroSizeFile = -6;
public static final int InvalidToken = -5;
public static final int InvalidArgument = -4;
public static final int InvalidFile = -3;
public static final int Cancelled = -2;
public static final int NetworkError = -1;
public static final int TimedOut = -1001;
public static final int UnknownHost = -1003;
public static final int CannotConnectToHost = -1004;
public static final int NetworkConnectionLost = -1005;

6).关于混淆配置:

混淆处理 对七牛的SDK不需要做特殊混淆处理,混淆时将七牛相关的包都排除就可以了。

在Android Studio中,混淆配置在 proguard-rules.pro 里面加上下面几行混淆代码就行:

-keep class com.qiniu.**{*;}
-keep class com.qiniu.**{public ();}
-ignorewarnings

注意:-ignorewarnings这个也是必须加的,如果不加这个编译的时候可能是可以通过的,但是release的时候还是会出现错误。

对于Eeclipse中也是一样的,在proguard-project.txt 文件附件同样的排除代码就可以了

-keep class com.qiniu.**{*;}
-keep class com.qiniu.**{public ();}
-ignorewarnings

7).为什么进度会在95% 停很久: 因为上传进度是用sdk写入socket的 字节数/总字节数 作为进度,但写入socket不等于服务器收到并且处理完成,中间还有一段时间,如果只是用字节数就会出现更怪异的情况,在100% 停留很久,所以综合考虑就使用了 95%这个值.

8).如何对文件名字做模糊查询: 如果前缀查询满足不了需求,想做多维度的查询,比如日期,userid, 文件名中的字段进行查询,可以通过开通Pandora 日志查询服务来满足。下面的例子里面需要在工作流上创建key, user, etag, mime, 四个字段的repo, 具体客户端做法如下,在上传结束后,再把结果打点到pandora 服务

import com.qiniu.android.storage.UploadManager;
import com.qiniu.android.bigdata.pipeline.Pipeline;
...
    String token = "从服务端SDK获取";
    UploadManager uploadManager = new UploadManager();
    String pipelineToken = "从服务端获取 或者 生成一个长时间的token";
    Pipeline pipe = new Pipeline();
    uploadManager.put("Hello, World!".getBytes(), "hello", token,
    new UpCompletionHandler() {
        @Override
        public void complete(String key, ResponseInfo info, JSONObject response) {
            Map inf = new HashMap();
            inf.put("key", key);
            inf.put("user", "userid");
            inf.put("etag", resp.getString("hash"));
            inf.put("mime", resp.getString("mimeType"));
            pipe.pump("keysearchRepo", inf, pipelineToken, new Pipeline.PumpCompleteHandler() {
                @Override
                public void complete(ResponseInfo inf2) {
                    ...
                }
            });
        }
    }, null);
...
