Picasso:UnknownServiceException:未为客户端启用CLEARTEXT通信

Question

我在我的应用程序中使用Picasso 2.5.2.它运行良好,但无法从第三方服务器之一加载图片.当我尝试从此站点加载图片时,我收到此错误:

当我在浏览器中打开此图像时,它会成功加载.网址看起来像http://somesite.com/path/to/file/123456.jpg.是毕加索的虫子吗？怎么解决？

Answer 1

是毕加索的虫子吗？

我不这么认为.OkHttp默认情况下似乎阻止非SSL通信.我几年没有使用OkHttp进行纯文本HTTP请求,但这是我在检查与该错误消息相关的代码时看到的内容.

怎么解决？

使用httpsURL.

如果某个恶魔般的狂人威胁要炸毁一个小城市,除非你使用普通http,请配置OkHttpClient通过它Builder,包括调用connectionSpecs()以指示你愿意支持哪种HTTP连接.例如:

.connectionSpecs(Arrays.asList(ConnectionSpec.MODERN_TLS, ConnectionSpec.CLEARTEXT))

将允许"现代TLS"(不完全确定什么是合格的)和普通的HTTP.

然后,将它OkHttpClient用于Picasso,以及使用OkHttp直接进行的任何操作.
