	 * @param [in]  indexbuf		媒体消息分片拉取，需要填入每次拉取的索引信息。首次不需要填写，后续每次调用只需要将上次调用返回的outindexbuf填入即可。
	  * @param [in]  proxy			使用代理的请求，需要传入代理的链接。如：socks5://10.0.0.1:8081 或者 http://10.0.0.1:8081
	 * @param [in]  passwd			代理账号密码，需要传入代理的账号密码。如 user_name:passwd_123
	 * @param [in]  timeout			超时时间，单位秒
	 * @param [out] media_data		返回本次拉取的媒体数据.MediaData结构体.内容包括data(数据内容)/outindexbuf(下次索引)/is_finish(拉取完成标记)

	 * @param [out] outindexbuf		返回下次访问需要的索引信息
	 * @param [out] data			返回本次访问返回的媒体数据内容，解密后内容，如分片数据需累加到文件存储.单次最大返回512K字节
	 * @param [out] is_finish		标识是否全部拉取完成，1完成、0未完成

	 
	 *
	 * @return 返回是否调用成功
	 *      0   - 成功
	 *      !=0 - 失败
