【问题描述】：

在通过改造库发送 Mutipart 或 JSON 数据时面临问题

改造界面

@Multipart
@POST("/api/v1/protected/updateprofile")
void uploadPhoto(@Part("name") String name,
                 @Part("image") TypedFile file,
                 Callback<ApiResponseModel> callback);

适配器代码

private RestApi restApi;
RestAdapter restAdapter = new RestAdapter.Builder().setClient(new OkClient(getClient())).setConverter(new GsonConverter(gson)).setRequestInterceptor(interceptor).setLogLevel(RestAdapter.LogLevel.FULL).setEndpoint(Config.baseUrl).build();
        restApi = restAdapter.create(RestApi.class);

发送 JSON 请求后生成的错误日志

我已经尝试增加Request Adapter中请求的超时时间

  private OkHttpClient getClient() {
        OkHttpClient client = new OkHttpClient();
        client.setConnectTimeout(30, TimeUnit.SECONDS);
        client.setReadTimeout(30, TimeUnit.SECONDS);
        return client;
    }

【解决方案1】：

几天前我遇到了这个错误，我发现你的解决方案是正确的，但需要更多时间

private OkHttpClient getClient() {
    OkHttpClient client = new OkHttpClient();
    client.setConnectTimeout(5, TimeUnit.MINUTES);
    client.setReadTimeout(5, TimeUnit.MINUTES);
    return client;
}

对于 OkHttp3

 private OkHttpClient getClient() {
    OkHttpClient client = new OkHttpClient.Builder()
    .connectTimeout(5, TimeUnit.MINUTES)
    .readTimeout(5, TimeUnit.MINUTES)
    .build();
    return client;
}

【讨论】：

这就是我发布我尝试过的东西的原因。
好吧，这不是一个解决方案！您必须隐含请求重试机制，而不是给它更多时间......
@Choletski 主要问题是时间问题，因为请求并不总是失败，你不能限制用户在带宽非常低的情况下上传非常小的文件

【解决方案2】：

对我来说，问题出在服务器端。

我必须通过更改 API 服务器上的 sysctl 配置来禁用 tcp_timestamp。此外，如果您在同一台机器上通过 TCP 运行其他服务，例如 Redis 等，您应该注意这对它们的影响。

从 Github 上的 issue 中找到此内容。
