这个错误的原因是什么 java.io.IOException: Content-Length 和 stream length 不一致

Question

我遇到这个错误

   java.io.IOException: Content-Length and stream length disagree

这行代码return response.body().bytes();

这是完整代码

编辑：经过一些 google 错误的原因来自 okhttp lib

if (contentLength != -1L && contentLength != bytes.size.toLong()) {
  throw IOException(
      "Content-Length ($contentLength) and stream length (${bytes.size}) disagree")
}

但是如何解决这个问题？

抛出异常是因为您调用了 InputStream inputStream = response.body().byteStream(); 然后又调用了 response.body().bytes();。

您可以使用 inputStream 或 return result.getBytes(); 中的 return 字节数组来代替 return。

从inputStream到bytes参考如下：

    public byte[] getBytesFromInputStream(InputStream inputStream) throws IOException {
        try {            
            byte[] buffer = new byte[8192];
            int bytesRead;
            ByteArrayOutputStream output = new ByteArrayOutputStream();
            while ((bytesRead = inputStream.read(buffer)) != -1) {
                output.write(buffer, 0, bytesRead);
            }
            return output.toByteArray();
        } catch (OutOfMemoryError error) {
            return null;
        }
    }

如果你在ResponseBody.class调试，你会看到如下截图：
