原因：接口返回的数据量太大报错，

解决办法：修改nginx缓存配置信息。

nginx原配置信息：

  proxy_buffer_size        16k;
  proxy_buffers            4 64k;
  proxy_busy_buffers_size 128k;
  proxy_temp_file_write_size 128k;

nginx修改后信息：

  proxy_buffer_size        256k;
  proxy_buffers            4 256k;
  proxy_busy_buffers_size 256k;
  proxy_temp_file_write_size 256k;

注意：

"proxy_busy_buffers_size"必须等于或大于"proxy_buffer_size"的最大值。
