在 Android Studio 項目中使用 htmlunit 時，沒有 Lorg/apache/http/conn/ssl/AllowAllHostnameVerifier 類型的 static 字段實例

Question

我在我的 Android Studio 項目中使用 htmlunit 2.36.0。 我成功編譯了 apk，但是當我嘗試獲取網頁時出現了一些運行時錯誤。 之前，我收到以下錯誤：

java.lang.BootstrapMethodError: Exception from call site

但是我可以通過在 gradle 中添加這個來解決這個問題：

compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
}

但是，現在我面臨另一個錯誤：

 java.lang.NoSuchFieldError: No static field INSTANCE of type Lorg/apache/http/conn/ssl/AllowAllHostnameVerifier; in class Lorg/apache/http/conn/ssl/AllowAllHostnameVerifier; or its superclasses (declaration of 'org.apache.http.conn.ssl.AllowAllHostnameVerifier' appears in /system/framework/framework.jar!classes3.dex)

        at com.gargoylesoftware.htmlunit.WebClient.getPage(WebClient.java:450)

顯然，在它自己的 class 或其超類中沒有 AllowAllHostnameVerifier 的 static 字段實例。 我不知道如何解決這個問題。

Answer 1

使用 android 的端口：

https://github.com/HtmlUnit/htmlunit-android

將此用作依賴項：

implementation("net.sourceforge.htmlunit:htmlunit-android:2.63.0")

Answer 2

正如hc.apache.org記錄的那樣：

AllowAllHostnameVerifier已棄用。 ( 4.4 ) 使用NoopHostnameVerifier

如果您將依賴項的版本降級到4.3 (2013~2015) 異常將得到解決。

implementation 'net.sourceforge.htmlunit:htmlunit:2.15'
