启用 ProGuard 时 Retrofit 2 不发送数据

Question

我尝试使用 Retrofit 2 登录我的用户。（基本上是使用基本 header 登录 URL 的 GET）它运行良好但是一旦我 ProGuard 它，Header 不再发送授权。（查看日志输出）

示例代码：

用户模型：

public interface UserService {

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

登录Activity：

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>;
}

日志（proguard）：

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>;
}

谢谢@xudshen

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>;
}

我还切换回了 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

添加到@Romain 的回答您需要添加到 proguard 文件

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

如果您正在使用@Header、@Query...

Answer 3

添加 Retrofit 2 与 Proguard 代码混淆器的兼容性

    -dontwarn retrofit.**
    -keep class retrofit.** { *; }
    -keepattributes Signature
    -keepattributes Exceptions
    -dontwarn java.lang.invoke.*
    -keep class com.elephantmobile.ui.remote.model.** { *; }
    -dontwarn retrofit.appengine.UrlFetchClient
    -keepclasseswithmembers class * {
        @retrofit.http.* <methods>;
    }
    -keepclassmembernames interface * {
        @retrofit.http.* <methods>;
    }
    -dontwarn retrofit2.Platform$Java8

Answer 4

另一个简单的解决方案使用来自支持注解的@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 5

对我来说，使用注解@SerializedName

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

   ...
 }

Answer 6

终于找到了。如果你使用 Gson 就试试这个，将此添加到改装 pro-guard 中：

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

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

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

Answer 7

您需要添加

 @SerializedName("yourInputParameter")

在您的 bean（模型）中 class 用于您的请求正文

例如

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

       ...
     }

它会起作用

因为现在 retrofit 无法读取您的请求正文，因为 proguard(minifyEnabled) 为真

在您的请求正文中添加 @SerializedName 之后，它肯定对您有用

Answer 8

将此添加到 progaurd

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

Answer 9

只需在您的数据上添加 @Keep class

 @Keep  
    data class ClassPojo(
      @SerializedName("MESSAGE") val message: String,  
      @SerializedName("STATUS") val status: String)
