如何检索表格和QUOT; POST＆QUOT;通过用C语言编写的cgi-bin程序数据
问题描述：
我试图用C语言编写的程序从HTML表单检索POST数据。
I am trying to retrieve POST data from html form using program written in C.
目前我使用的时刻：
char *formdata = getenv("QUERY_STRING");
if(formdata == NULL) /* no data retrieved */
这似乎是工作的罚款与形式GET的方法，但不是以POST的方法。我该如何找回POST数据？
This seems to be working fine with form "GET" method but not with "POST" method. How do I retrieve POST data?
答
POST数据附加到请求头，双换行符后。在CGI-BIN的环境中，你从标准输入读取。
POST data is appended to the request header, after a double newline. In a CGI-BIN environment, you read it from STDIN.
但是要注意，服务器的不需要在POST数据的最后送你一个EOF字符（或终止指标）。从来没有超过CONTENT_LENGTH字节读更多。
Be warned that the server IS NOT REQUIRED to send you an EOF character (or some termination indicator) at the end of the POST data. Never read more than CONTENT_LENGTH bytes.
