Question

我使用RxJava和Retrofit发出网络请求，但偶尔会收到错误反馈。在ApiManager.java:216是我常用参数的添加方法。

错误消息：

ApiManager.java:216：

public static class SignInterceptor implements Interceptor {

        @Override
        public Response intercept(Chain chain) throws IOException {
            Request request = chain.request();
          //...add sign parameter
            return chain.proceed(request);//line: 216
        }
    }

在OkHttpClient：

OkHttpClient.Builder builder = new OkHttpClient.Builder()
                .addInterceptor(new SignInterceptor());

以上是相关代码。错误消息仅偶尔出现。测试期间从未发生过。我该如何解决这个问题？

如建议的那样，由于没有注册Subscriber并将错误传递给RxJavaPlugins.setErrorHandler()

，因此没有发生全局错误，因此发生了错误。

但是，问题的症结似乎是因为

okhttp3.internal.http2.Http2Stream.waitForIo(Http2Stream.java:579)

在处理发出API调用的Rx流时，正在等待并中断。

从堆栈跟踪中看，您似乎正在运行：

  /**
   * Removes and returns the stream's received response headers, blocking if necessary until headers
   * have been received. If the returned list contains multiple blocks of headers the blocks will be
   * delimited by 'null'.
   */
  public synchronized List<Header> takeResponseHeaders() throws IOException {

因此，您需要做的是确保取消订阅Rx流时进行此API调用时，首先要取消与该流的连接（而我只是在这里猜测，它是开放的或包含多个标头块））。这应该照顾持续的等待并解决崩溃。

但是，只需为全局处理程序添加插件即可快速解决，因为它将停止崩溃并允许您恢复。
