CGI 脚本，使用终端 (OS X) 将 `printf` 保存到文件

问题描述

我之前问过一个关于如何读取 POST 请求的问题 使用您自己的本地服务器(在 OS X 上)

I asked a question earlier about how to read a POST request with your own local server (On OS X)

现在我的问题是我无法保存在我的服务器上收到的 POST 数据.

Now my problem is that i can't save the POST Data received on my server.

我目前使用 while true;do nc -l 10000 接收并显示从我的 iOS 设备发送的 POST 消息，它运行良好.

I currently use while true; do nc -l 10000 < /dev/null ; printf '\n\n\n'; done to receive and display the POST Message sent from my iOS device, and it workes perfectly.

但是我如何保存 printf 输出?

But how can i save the printf output?

我尝试使用本地 .sh 文件并使用以下代码发送 POST 请求(没有成功):

I tried using a local .sh file and send the POST Request withe the following code (with no success):

#!/bin/sh

printf 'Content-type: text/plain\r\n\r\n'
cat > /MYPATH/post-data
echo OK

我也尝试直接从终端保存文件(也没有成功):

I also tried to save the file directly from Terminal (also without success):

while true; do nc -l 10000 < /dev/null ; printf 'Content-type: text/plain\r\n\r\n' >> /MYPATH/post-data echo OK; done

然而，我在终端中使用的代码实际上创建了 post-data 文件，但只有 Content-type: text/plain 文本，而不是实际的 POST(终端显示帖子).

However the code I used in Terminal actually created the post-data file, but only with the Content-type: text/plain text, and not the actual POST (Terminal displayed the post tho).

我需要今晚回答这个问题，所以如果你能帮助我解决这个问题，我将不胜感激.

I need this answered tonight, so I would really appreciate it if you could help me on this one.

基本综述:我想将包含 POST 请求数据的 printf 保存到文件中.

Basic roundup: I want to save the printf that contains the POST Request data to a file.

推荐答案

我相信你会想要这个:

while true; do (printf 'Content-type: text/plain\r\n\r\n'; nc -l 10000 < /dev/null) >> /MYPATH/post-data; echo OK; done

不确定您想要哪一侧的内容类型...

Not sure which side you want the Content-type on...
