我想连接到webSocket，但发生错误。怎么解决？或者它可能是服务器端的错误？

implementation 'com.squareup.okhttp3:okhttp:3.9.1'

代码：

final Request request = new Request.Builder()
            .get()
            .url("http://develop.by:8000")
           .build();

OkHttpClient okHttpClient = new OkHttpClient.Builder()
                .readTimeout(30, TimeUnit.SECONDS)
                .writeTimeout(30, TimeUnit.SECONDS)
                .build();

WebSocket webSocket = okHttpClient.newWebSocket(request, new WebSocketListener() {...}

错误：

根据this问题禁用gzip

   .header("Accept-Encoding", "identity")

Answer 2

在尝试将一些图像上传到服务器时遇到了相同的问题，经过适当的研究，结果发现问题出在与应用程序连接的服务器上。从要通过服务器发送的表单数据的键值对中，发现某个键正确发送了图像，而其他键则没有。我建议您在使用下一种方法之前，使用Retroman等工具对通过Retrofit连接的API链接进行正确的测试，以确定服务器端是否正常工作。

java.io.EOFException：\ n not found：limit = 0 content = ...
