Question

我尝试使用Retrofit 2登录我的用户。（基本上是使用基本标题对登录URL进行GET）它运行良好但是一旦我ProGuard它，标题授权就不再发送了。（见日志输出）

示例代码：

用户模型：

public interface UserService {

    @GET(GET_LOGIN)
    Observable<User> login(@Header("Authorization") String basic);
}

登录活动：

public void onClick(View v) {
    mRetrofit.create(UserService.class)
             .login(Credentials.basic(email, password))
             .subscribeOn(Schedulers.io())
             .observeOn(AndroidSchedulers.mainThread())
             .subscribe(user -> {
                UserHelper.save(LoginActivity.this, user);
             }, throwable -> Dog.d);
}

Proguard文件：

# Retrofit
-dontwarn retrofit2.** 
-dontwarn org.codehaus.mojo.**
-keep class retrofit2.** { *; }
-keepattributes Signature
-keepattributes Exceptions
-keepattributes *Annotation*
-keepclasseswithmembers class * {
    @retrofit.* <methods>;
}

-keepclasseswithmembers interface * {
    @retrofit.* <methods>;
}

Answer 1

我终于成功了。这是关于Retrofit 2

的proguard配置

# Retrofit
-dontwarn retrofit2.**
-dontwarn org.codehaus.mojo.**
-keep class retrofit2.** { *; }
-keepattributes Signature
-keepattributes Exceptions
-keepattributes *Annotation*

-keepattributes RuntimeVisibleAnnotations
-keepattributes RuntimeInvisibleAnnotations
-keepattributes RuntimeVisibleParameterAnnotations
-keepattributes RuntimeInvisibleParameterAnnotations

-keepattributes EnclosingMethod

-keepclasseswithmembers class * {
    @retrofit2.* <methods>;
}

-keepclasseswithmembers interface * {
    @retrofit2.* <methods>;
}

感谢@ xudshen

<强>更新

主要问题：我使用了proguard-android-optimize所以我应该添加：

-keepclasseswithmembers class * {
    @retrofit2.http.* <methods>;
}

我还切换回由square提供的常规Retrofit 2 proguard配置：

# Platform calls Class.forName on types which do not exist on Android to determine platform.
-dontnote retrofit2.Platform
# Platform used when running on RoboVM on iOS. Will not be used at runtime.
-dontnote retrofit2.Platform$IOS$MainThreadExecutor
# Platform used when running on Java 8 VMs. Will not be used at runtime.
-dontwarn retrofit2.Platform$Java8
# Retain generic type information for use by reflection by converters and adapters.
-keepattributes Signature
# Retain declared checked exceptions for use by a Proxy instance.
-keepattributes Exceptions

Answer 2

添加@ Romain的回答您需要添加到proguard文件

如果您正在使用@Header，@ Query ...

此处参考Retrofit2 proguard remove param

Answer 3

另一个简单的解决方案从支持注释中使用@keep https://developer.android.com/reference/android/support/annotation/Keep.html

@Keep
interface APIService 
{

    @GET("/user/auth")
    fun auth(@Header(Constants.AUTHORIZATION) authorization: String): Call<User>

}

Answer 4

对我来说使用注释@SerializedName

public class YourJsonClass{
   @SerializedName("name") String username;

   ...
 }

Answer 5

使用Proguard代码Obfuscator添加Retrofit 2兼容性

package test;

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JTextField;

public class Test extends JFrame {

private static final long serialVersionUID = -5624404136485946868L;

String userWord = "";
JTextField userInput;

public Test() {
    JFrame jf = new JFrame();
    JPanel panel = new JPanel();
    JLabel jl = new JLabel("Test");
    JButton jButton = new JButton("Click");
    userInput = new JTextField("", 30);
    jButton.addActionListener( (e) -> {
        submitAction();
    });
    jf.setSize(500, 500);
    jf.setVisible(true);
    jf.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    jf.add(panel);
    panel.add(jl);
    panel.add(userInput);
    panel.add(jButton);
}

private void submitAction() {
    userWord = userInput.getText();
    System.out.println(userWord);//do whatever you want with the variable, I just printed it to the console
}

public static void main(String[] args) {
    new Test();
}

Answer 6

最后我找到了。如果您使用Gson，请尝试此操作，将此添加到改造后卫：

-keepclassmembers,allowobfuscation class * {
  @com.google.gson.annotations.SerializedName <fields>;
}

然后在模型中使用@SerializedName("name")。kotlin示例：

class PaymentRequestModel (
    @SerializedName("name")
    @Expose
    var name : String = "",
}

Answer 7

将此添加到 progaurd

-keep public class com.data.YOurDataModels.* {
  public void set*(***);
  public *** get*();
  public protected private *;
}

Answer 8

您需要添加

 @SerializedName("yourInputParameter")

在您的bean（模型）类中作为请求正文

例如

 public class YourClass{
       @SerializedName("yourInputParameter") String yourInputParameter;

       ...
     }

它将起作用

因为现在改进，因为proguard（minifyEnabled）为true，所以无法读取您的请求正文

在请求正文中添加 @SerializedName 后，它肯定会为您服务

启用ProGuard时，改造2不发送数据
