java - 在 Android Studio 项目中使用 htmlunit 时，没有 Lorg/apache/http/conn/ssl/AllowAllHostnameVerifier 类型的静态字段实例

Question

我在我的 Android Studio 项目中使用 htmlunit 2.36.0。我成功编译了 apk，但是当我尝试获取网页时出现了一些运行时错误。
之前，我收到以下错误:

java.lang.BootstrapMethodError: Exception from call site

但是我可以通过在 gradle 中添加这个来解决这个问题:

compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
}

但是，现在我面临另一个错误:

 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)

显然，在它自己的类或其父类(super class)中没有 AllowAllHostnameVerifier 的静态字段实例。我不知道如何解决这个问题。

Answer 1

如hc.apache.org记录:
AllowAllHostnameVerifier已弃用。 ( 4.4 ) 使用 NoopHostnameVerifier
如果您将依赖项的版本降级为 4.3 (2013~2015) 异常将得到解决。

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