final int statusTest = responseTest.getStatus(); // here i get 204, because i make server return 204 then there is nothing.
String body responseTest.getAsString() // here i get empty which is correct.

Answer 1

我添加了一个网络拦截器,并为okhttp3客户端添加了关闭连接头.

okHttpClient = new OkHttpClient.Builder()
                .addNetworkInterceptor(new Interceptor() {
                    @Override
                    public Response intercept(Chain chain) throws IOException {
                        Request request = chain.request().newBuilder().addHeader("Connection", "close").build();
                        return chain.proceed(request);
                    }
                })
                .build();

这解决了问题.希望能帮助到你!

Answer 2

在快速连续发送两个POST请求时也会收到此响应错误.解决方案是为这两个请求添加标题"Connection:close".

Answer 3

您可以通过@Headers("Connection:close")在改装方法上设置标题值来解决此问题.
这对我有用.

Answer 4

某些原因导致前面的 HTTP 请求的响应正文长度出现问题，从而导致池连接损坏。

前面的请求被 OkHttp 解释为没有主体，但它有这个主体：

{"Data":[],"CustomStatusCode":200,"Status":"success"}

这可能是服务器中的错误，或者是 OkHttp 中的错误，具体取决于前面的 URL 发送的标头和代码。如果您能粘贴此故障之前的请求，我们就可以找出是谁的错！
