如何正确解压并查看使用curl从对网站API的POST请求获得的响应

Question

我正在尝试使用curl 命令行向网站的API 发送POST 请求。我通过数据包嗅探获得了请求标头和正文。执行curl命令后，响应将保存在

output.txt

中。然而，经过检查，该文件以意外的格式出现。可以根据标头使用 gzip、deflate 或 Brotli 来压缩响应。我尝试过使用

brotli

、

inflate

、

zcat

和

gzip -d

等各种命令来解压缩文件，但都没有成功。如何正确解压并查看

output.txt

中的响应？

以下是我在解压文件过程中尝试过的命令

output.txt

┌──(kali㉿localhost)-[~]

└─$ brotli -d output.txt

input file [output.txt] suffix mismatch

┌──(kali㉿localhost)-[~]

└─$ inflate output.txt

Usage: inflate [OPTIONS] START END [AMOUNT]

Try 'inflate --help' for help.

Error: Invalid value for 'START': 'output.txt' is not a valid integer.

┌──(kali㉿localhost)-[~]

└─$ zcat output.txt

gzip: output.txt: not in gzip format

┌──(kali㉿localhost)-[~]

└─$ gzip -d output.txt

gzip: output.txt: unknown suffix -- ignored

Answer 1

1. 重命名文件以指示 Brotli 压缩：

mv output.txt output.txt.br

2. 删除原文件：

rm output.txt

3. 解压Brotli文件：

brotli -d output.txt.br

执行这些命令后，解压缩的响应应该在新创建的output.txt中可用。这为我解决了这个问题，我希望它可以帮助其他面临类似问题的人。
