socket.io和okhttp3冲突

Question

我在 Android 项目中使用 okhttp3 进行网络连接，io.socket:socket.io-client:0.8.3 用于 socket.io 连接。

以下是我的 gradle 文件的摘录。

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile group: 'com.google.code.gson', name: 'gson', version: '2.4'
    compile('com.digits.sdk.android:digits:2.0.5@aar') {
        transitive = true;
    }
    compile 'com.android.support:appcompat-v7:24.2.1'
    compile 'com.android.support:support-v4:24.2.1'
    compile 'com.android.support:cardview-v7:24.2.1'
    compile 'com.android.support:recyclerview-v7:24.2.1'
    compile 'com.squareup.okhttp3:okhttp:3.6.0'
    compile 'com.squareup.okhttp3:okhttp-ws:3.4.2'
    testCompile 'junit:junit:4.12'
    compile('io.socket:socket.io-client:0.8.3') {
        exclude group: 'org.json', module: 'json'
    }
}

然而当我运行项目抛出以下异常：

java.lang.NoSuchMethodError: No direct method <init>(Lokhttp3/Request;Lokhttp3/WebSocketListener;Ljava/util/Random;)V in class Lokhttp3/internal/ws/RealWebSocket; or its super classes (declaration of 'okhttp3.internal.ws.RealWebSocket' appears in /data/data/com.fouadkada.mysioapplicationpoc/files/instant-run/dex/slice-okhttp-ws-3.4.2_208c84938ec045e30eddb95384859b3e594c4d81-classes.dex)

我已经尝试了此处建议的解决方案：https://github.com/socketio/socket.io-client-java/issues/337 但没有成功

有什么想法吗？

Answer 1

看起来 Socket IO 不支持 OkHttp 3.5.0 中的新 websockets API launched。

您需要向他们发送拉取请求以更新其实现以使用 OkHttp 的新 websockets API。或者您可以将自己的代码回滚到 OkHttp 3.4.1。

Answer 2

在 socket github 页面的问题部分发帖后。io-client-java，我得到了解决问题的答案。

解决方案是删除对 okhttp-ws:3.4.2 的依赖，因此依赖块变成如下：

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile group: 'com.google.code.gson', name: 'gson', version: '2.4'
    compile('com.digits.sdk.android:digits:2.0.5@aar') {
        transitive = true;
    }
    compile 'com.android.support:appcompat-v7:24.2.1'
    compile 'com.android.support:support-v4:24.2.1'
    compile 'com.android.support:cardview-v7:24.2.1'
    compile 'com.android.support:recyclerview-v7:24.2.1'
    compile 'com.squareup.okhttp3:okhttp:3.6.0'
    testCompile 'junit:junit:4.12'
    compile('io.socket:socket.io-client:0.8.3') {
        exclude group: 'org.json', module: 'json'
    }
}
