Android调试工具 stetho

项目地址:https://github.com/facebook/stetho


在android studio中使用:


1. 添加jar  (下载地址:https://github.com/facebook/stetho/releases/tag/v1.1.0  )

    (需要 stetho-1.1.0.jar    和  stetho-urlconnection-1.1.0.jar

    添加完成后在bulid.gradle中显示:

    


2 在你的application类中添加:Stetho.initialize(Stetho..... 初始化Stetho工具

public class myApplication extends Application {

   @Override

   public void onCreate() {

       super.onCreate();

       Stetho.initialize(Stetho

               .newInitializerBuilder(this)

               .enableDumpapp(Stetho.defaultDumperPluginsProvider(this))

               .enableWebKitInspector(

                       Stetho.defaultInspectorModulesProvider(this)).build());

   }

}



3 开启网络调试

    a.假如使用 HttpURLConnection 需要使用StethoURLConnectionManager类(在stetho-urlconnection JAR中) 并且注意在请求头中添加Accept-Encoding: gzip


以下是官方封装的一个Networker请求类

public class Networker {

 private static Networker sInstance;

 private final Executor sExecutor = Executors.newFixedThreadPool(4);

 private static final int READ_TIMEOUT_MS = 10000;

 private static final int CONNECT_TIMEOUT_MS = 15000;

 private static final String HEADER_ACCEPT_ENCODING = "Accept-Encoding";

 private static final String GZIP_ENCODING = "gzip";

 public static synchronized Networker get() {

   if (sInstance == null) {

     sInstance = new Networker();

   }

   return sInstance;

 }

 private Networker() {

 }

 public void submit(HttpRequest request, Callback callback) {

   sExecutor.execute(new HttpRequestTask(request, callback));

 }

 private class HttpRequestTask implements Runnable {

   private final HttpRequest request;

   private final Callback callback;

   private final StethoURLConnectionManager stethoManager;

   public HttpRequestTask(HttpRequest request, Callback callback) {

     this.request = request;

     this.callback = callback;

     stethoManager = new StethoURLConnectionManager(request.friendlyName);

   }

   @Override

   public void run() {

     try {

       HttpResponse response = doFetch();

       callback.onResponse(response);

     } catch (IOException e) {

       callback.onFailure(e);

     }

   }

   private HttpResponse doFetch() throws IOException {

     HttpURLConnection conn = configureAndConnectRequest();

     try {

       ByteArrayOutputStream out = new ByteArrayOutputStream();

       InputStream rawStream = conn.getInputStream();

       try {

         // Let Stetho see the raw, possibly compressed stream.

         rawStream = stethoManager.interpretResponseStream(rawStream);

         InputStream decompressedStream = applyDecompressionIfApplicable(conn, rawStream);

         if (decompressedStream != null) {

           copy(decompressedStream, out, new byte[1024]);

         }

       } finally {

         if (rawStream != null) {

           rawStream.close();

         }

       }

       return new HttpResponse(conn.getResponseCode(), out.toByteArray());

     } finally {

       conn.disconnect();

     }

   }

   private HttpURLConnection configureAndConnectRequest() throws IOException {

     URL url = new URL(request.url);

     // Note that this does not actually create a new connection so it is appropriate to

     // defer preConnect until after the HttpURLConnection instance is configured.  Do not

     // invoke connect, conn.getInputStream, conn.getOutputStream, etc before calling

     // preConnect!

     HttpURLConnection conn = (HttpURLConnection)url.openConnection();

     try {

       conn.setReadTimeout(READ_TIMEOUT_MS);

       conn.setConnectTimeout(CONNECT_TIMEOUT_MS);

       conn.setRequestMethod(request.method.toString());

       // Adding this disables transparent gzip compression so that we can intercept

       // the raw stream and display the correct response body size.

       requestDecompression(conn);

       SimpleRequestEntity requestEntity = null;

       if (request.body != null) {

         requestEntity = new ByteArrayRequestEntity(request.body);

       }

       stethoManager.preConnect(conn, requestEntity);

       try {

         if (request.method == HttpMethod.POST) {

           if (requestEntity == null) {

             throw new IllegalStateException("POST requires an entity");

           }

           conn.setDoOutput(true);

           requestEntity.writeTo(conn.getOutputStream());

         }

         // Ensure that we are connected after this point.  Note that getOutputStream above will

         // also connect and exchange HTTP messages.

         conn.connect();

         stethoManager.postConnect();

         return conn;

       } catch (IOException inner) {

         // This must only be called after preConnect.  Failures before that cannot be

         // represented since the request has not yet begun according to Stetho.

         stethoManager.httpExchangeFailed(inner);

         throw inner;

       }

     } catch (IOException outer) {

       conn.disconnect();

       throw outer;

     }

   }

 }

 private static void requestDecompression(HttpURLConnection conn) {

   conn.setRequestProperty(HEADER_ACCEPT_ENCODING, GZIP_ENCODING);

 }

 @Nullable

 private static InputStream applyDecompressionIfApplicable(

     HttpURLConnection conn, @Nullable InputStream in) throws IOException {

   if (in != null && GZIP_ENCODING.equals(conn.getContentEncoding())) {

     return new GZIPInputStream(in);

   }

   return in;

 }

 private static void copy(InputStream in, OutputStream out, byte[] buf) throws IOException {

   if (in == null) {

     return;

   }

   int n;

   while ((n = in.read(buf)) != -1) {

     out.write(buf, 0, n);

   }

 }

 public static class HttpRequest {

   public final String friendlyName;

   public final HttpMethod method;

   public final String url;

   public final byte[] body;

   public static Builder newBuilder() {

     return new Builder();

   }

   HttpRequest(Builder b) {

     if (b.method == HttpMethod.POST) {

       if (b.body == null) {

         throw new IllegalArgumentException("POST must have a body");

       }

     } else if (b.method == HttpMethod.GET) {

       if (b.body != null) {

         throw new IllegalArgumentException("GET cannot have a body");

       }

     }

     this.friendlyName = b.friendlyName;

     this.method = b.method;

     this.url = b.url;

     this.body = b.body;

   }

   public static class Builder {

     private String friendlyName;

     private HttpMethod method;

     private String url;

     private byte[] body = null;

     Builder() {

     }

     public Builder friendlyName(String friendlyName) {

       this.friendlyName = friendlyName;

       return this;

     }

     public Builder method(HttpMethod method) {

       this.method = method;

       return this;

     }

     public Builder url(String url) {

       this.url = url;

       return this;

     }

     public Builder body(byte[] body) {

       this.body = body;

       return this;

     }

     public HttpRequest build() {

       return new HttpRequest(this);

     }

   }

 }

 public static enum HttpMethod {

   GET, POST

 }

 public static class HttpResponse {

   public final int statusCode;

   public final byte[] body;

   HttpResponse(int statusCode, byte[] body) {

     this.statusCode = statusCode;

     this.body = body;

   }

 }

 public interface Callback {

   public void onResponse(HttpResponse result);

   public void onFailure(IOException e);

 }

}

我自己试着调用network类:

public void sendOneReq() {

       Networker.HttpRequest request = Networker.HttpRequest.newBuilder()

               .friendlyName("Bai Du")

               .method(Networker.HttpMethod.GET)

               .url("http://www.baidu.com")

               .build();

       Networker.get().submit(request, mStoreRssResponse);

   }

   private final Networker.Callback mStoreRssResponse = new Networker.Callback() {

       @Override

       public void onResponse(Networker.HttpResponse result) {

           if (result.statusCode == 200) {

               String page22222=new String(result.body);

               System.out.println("page22222 : "+page22222);

           }else{

               System.out.println("result.statusCode is not 200");

           }

       }

       @Override

       public void onFailure(IOException e) {

           System.out.println("onFailure");

       }

   };


b.使用okhttp

工程依赖包如下:
commons-cli-1.2.jar
okhttp-2.3.0.jar
okio-1.3.0.jar
stetho-1.0.1.jar

stetho-okhttp-1.0.1.jar


一个简单使用:

  1. public class Net {
  2.    private static final boolean debug = true;
  3.    private static OkHttpClient okHttpClient = new OkHttpClient();
  4.    static {
  5.        if (debug) {
  6.            okHttpClient.networkInterceptors().add(new StethoInterceptor());
  7.        }
  8.    }
  9.    public static final void askBaidu() {
  10.        Request request = new Request.Builder().url("http://www.baidu.com")
  11.                .build();
  12.        try {
  13.            Response response = okHttpClient.newCall(request).execute();
  14.            String reslut = response.body().string();
  15.        } catch (IOException e) {
  16.            e.printStackTrace();
  17.        }
  18.    }
  19. }



4 查看结果:

    在Chrome浏览器中输入  chrome://inspect/#devices 

显示:

注: 真机中是不会显示webView的。。

点击 inspect 显示:


补充:

    好像这个东西在某些机子上会崩溃。。
