okhttp - 非法状态异常 : response is not eligible for a body and must not be closed

Question

有时我们会得到这个异常处理响应。 Response 似乎有一个 null 主体。

代码是这样的:

try (Response response = client.newCall(request).execute()) {
  // do stuff with the response
} catch (Exception e) {
  log.error("Something wrong", e);
}

在 do stuff with response block 执行后，在 Response 上自动调用的 close() 方法引发异常。

堆栈跟踪:

java.lang.IllegalStateException: response is not eligible for a body and must not be closed
    at okhttp3.Response.close(Response.java:281)

我们是否遗漏了什么？
谢谢。

我认为你可以调用 response.body.close() 与 response.close() 相同，并在关闭前检查 body 是否为 null。

        ResponseBody responseBody = null;
        try {
            Response response = client.newCall(request).execute();
            responseBody = response.body();
            // do stuff with the response
        } catch (Exception e) {
            log.error("Something wrong", e);
        } finally {
            if (responseBody != null) {
                responseBody.close();
            }
        }
