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 INSTANCE

Question

我在 Android Studio 项目中使用 htmlunit 2.36.0。我成功编译了 apk，但当我尝试获取网页时遇到一些运行时错误。之前，我收到以下错误：

java.lang.BootstrapMethodError: Exception from call site

但我可以通过在 gradle 中添加以下内容来解决这个问题：

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，在它自己的类或其超类中没有AllowAllHostnameVerifier的静态字段实例。我不知道如何解决这个问题。

Answer 1

正如hc.apache.org记录的：

AllowAllHostnameVerifier已弃用。（4.4） 使用NoopHostnameVerifier

如果将依赖项的版本降级到4.3（2013~2015），异常将得到解决。

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