奇怪的问题: SSLException: Unrecognized SSL message, plaintext connection?

开发调优

逛l站的时候发现一个天气api,就想着调用一下…
天气信息查询API - 资源荟萃 - LINUX DO
代码如下:
这个SSLContext 去掉也会报这个错

        SSLContext sslContext = SSLContextBuilder.create().setTrustManagers(DefaultTrustManager.INSTANCE).build();

        String res = HttpRequest.get("https://api.lolimi.cn/API/weather/?city=%E6%88%90%E9%83%BD")
                .setSSLSocketFactory(sslContext.getSocketFactory())
                .execute()
                .body();

堆栈信息:
