Glide加载volleyball.ir图片失败：No address associated with hostname问题排查

问题描述 #

使用Glide加载volleyball.ir域名下的图片（示例链接：https://volleyball.ir/wp-content/uploads/2023/11/IMG_0490-01.jpg）时失败，该图片可在浏览器正常显示，其他图片加载正常。

相关代码 #

val image_url = "https://volleyball.ir/wp-content/uploads/2023/11/IMG_0490-01.jpg"

Glide.with(G.context).load(image_url).into(img)

解决方案 #

从报错日志的UnknownHostException可以看出，核心问题是设备无法解析volleyball.ir域名，结合Glide的配置问题，按以下步骤处理：

1. 确认网络权限 #

确保AndroidManifest.xml中已添加必要的网络权限：

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

同时检查应用的系统权限设置，确认未被限制网络访问。

2. 解决DNS解析失败问题 #

部分网络环境下无法正常解析该域名，可通过Glide自定义OkHttp客户端指定DNS或手动解析IP：

• 首先添加依赖到build.gradle（版本需与Glide匹配）：

  implementation 'com.squareup.okhttp3:okhttp:4.11.0'
  implementation 'com.github.bumptech.glide:okhttp3-integration:4.16.0'
  annotationProcessor 'com.github.bumptech.glide:compiler:4.16.0'
  

• 创建自定义Glide模块，配置DNS：

  import com.bumptech.glide.annotation.GlideModule
  import com.bumptech.glide.module.AppGlideModule
  import com.bumptech.glide.load.model.GlideUrl
  import com.github.bumptech.glide.integration.okhttp3.OkHttpUrlLoader
  import okhttp3.OkHttpClient
  import okhttp3.Dns
  import java.net.InetAddress
  
  @GlideModule
  class CustomGlideModule : AppGlideModule() {
      override fun registerComponents(context: android.content.Context, glide: com.bumptech.glide.Glide, registry: com.bumptech.glide.Registry) {
          val okHttpClient = OkHttpClient.Builder()
              .dns(Dns { hostname ->
                  if (hostname == "volleyball.ir") {
                      // 先通过浏览器ping volleyball.ir获取真实IP，替换此处
                      listOf(InetAddress.getByName("185.220.101.10"))
                  } else {
                      Dns.SYSTEM.lookup(hostname)
                  }
              })
              .build()
          registry.replace(GlideUrl::class.java, java.io.InputStream::class.java, OkHttpUrlLoader.Factory(okHttpClient))
      }
  }
  

3. 处理Glide模块警告 #

上述自定义模块已包含@GlideModule注解，配合添加的compiler依赖，可解决Failed to find GeneratedAppGlideModule的警告。

4. 清除Glide缓存 #

若缓存导致异常，可调用以下代码清除缓存：

Glide.get(G.context).clearDiskCache()
Glide.get(G.context).clearMemory()
