我正在创建一个zip文件，其中两个文件使用zlib压缩，而另两个是未压缩的文件。当我尝试将其解压缩时，出现以下错误，并且其中一个压缩文件的内容被未压缩文件的内容覆盖。
zipinfo 2019-08-14T13_21_59-symptomreport.zip 存档：2019-08-14T13_21_59-symptomreport.zip 压缩文件大小：2378字节，条目数：4 rw-r--r-- 2.0 unx 21959 b- defN 14年8月19日13:21 symptomreport / distro / networking_info / networking_info.output.log rw-r--r-- 2.0 unx 518 b- defN 14年8月19日13:21 symptomreport / distro / networking_info / networking_info.execution.log -rw-r--r-- 2.0 unx 140 bstor 14年8月19日13:21 symptomreport / metadata.yaml rw ------- 2.0 unx 1205 b-tor 14年8月19日13:21 symptomreport / execution.log 4个文件，23822字节未压缩，3534字节压缩：85.2％

压缩文件将作为流数据传递到zipfile，并使用zlib进行压缩。流数据是某些命令linux命令的输出作为tar对象。

我希望解压缩后内容正确而不覆盖内容。
