我在arm上配置了boa 服务器，其主目录为/www/，cgi-bin目录为/www/cgi-bin
我写了一个html网页，名称为callCgi.html，功能是实现点击form按钮，调用在cgi-bin下面的一个用c写好的输出“你好”的cgi程序，该脚本名称为hellorld.cgi。
问题如下:
首先，我在浏览器上直接输入调用这个c脚本，输出结果正常，即浏览器输入10.1.0.79/cgi-bin/helloworld.cgi，浏览器可以显示正常的输出结果
但是当在浏览器中用html的form调用时，就出现问题了，我在浏览器中输入10.1.0.79/callCgi.html,起内容可以显示，但是我点击call想调用c脚本的时候，出现了如下错误：
"400 Bad Request
Your client has issued a malformed or illegal request. "
请问大虾们这是什么问题呢？
附相关码如下：
callCgi.html代码:
<HTML>
<HEAD>
<HEAD>
<BODY>
<FORM ACTION="/cgi-bin/helloworld.cgi" METHOD=POST>
<INPUT TYPE=submit VALUE=call>
</FORM>
</BODY>
</HTML>
我的boa.conf内容
# Boa v0.94 configuration file
# File format has not changed from 0.93
# File format has changed little from 0.92
# version changes are noted in the comments
#
# The Boa configuration file is parsed with a lex/yacc or flex/bison
# generated parser. If it reports an error, the line number will be
# provided; it should be easy to spot. The syntax of each of these
# rules is very simple, and they can occur in any order. Where possible
# these directives mimic those of NCSA httpd 1.3; I saw no reason to
# introduce gratuitous differences.

# The "ServerRoot" is not in this configuration file. It can be compiled
# into the server (see defines.h) or specified on the command line with
# the -c option, for example:
#
# boa -c /usr/local/boa
# Port: The port Boa runs on. The default port for http servers is 80.
# If it is less than 1024, the server must be started as root.
Port 80
# Listen: the Internet address to bind(2) to. If you leave it out,
# it takes the behavior before 0.93.17.2, which is to bind to all
# addresses (INADDR_ANY). You only get one "Listen" directive,
# if you want service on multiple IP addresses, you have three choices:
# 1. Run boa without a "Listen" directive
# a. All addresses are treated the same; makes sense if the addresses
# are localhost, ppp, and eth0.
# b. Use the VirtualHost directive below to point requests to different
# files. Should be good for a very large number of addresses (web
# hosting clients).
# 2. Run one copy of boa per IP address, each has its own configuration
# with a "Listen" directive. No big deal up to a few tens of addresses.
# Nice separation between clients.
# The name you provide gets run through inet_aton(3), so you have to use dotted
# quad notation. This configuration is too important to trust some DNS.
#Listen 192.68.0.5
# User: The name or UID the server should run as.
# Group: The group name or GID the server should run as.
#User root
#Group root
User 0
Group 0
# ServerAdmin: The email address where server problems should be sent.
# Note: this is not currently used, except as an environment variable
# for CGIs.
#ServerAdmin root@localhost
# ErrorLog: The location of the error log file. If this does not start
# with /, it is considered relative to the server root.
# Set to /dev/null if you don't want errors logged.
# If unset, defaults to /dev/stderr
#ErrorLog /dev/null
ErrorLog /dev/console
# Please NOTE: Sending the logs to a pipe ('|'), as shown below,
# is somewhat experimental and might fail under heavy load.
# "Usual libc implementations of printf will stall the whole
# process if the receiving end of a pipe stops reading."
#ErrorLog "|/usr/sbin/cronolog --symlink=/var/log/boa/error_log /var/log/boa/error-%Y%m%d.log"
# AccessLog: The location of the access log file. If this does not
# start with /, it is considered relative to the server root.
# Comment out or set to /dev/null (less effective) to disable
# Access logging.
AccessLog /dev/null
# Please NOTE: Sending the logs to a pipe ('|'), as shown below,
# is somewhat experimental and might fail under heavy load.
# "Usual libc implementations of printf will stall the whole

# UseLocaltime: Logical switch. Uncomment to use localtime
# instead of UTC time
#UseLocaltime
# VerboseCGILogs: this is just a logical switch.
# It simply notes the start and stop times of cgis in the error log
# Comment out to disable.
#VerboseCGILogs
# ServerName: the name of this server that should be sent back to
# clients if different than that returned by gethostname + gethostbyname
#ServerName www.your.org.here
ServerName www.utu.com.cn
# VirtualHost: a logical switch.
# Comment out to disable.
# Given DocumentRoot /var/www, requests on interface 'A' or IP 'IP-A'
# become /var/www/IP-A.
# Example: http://localhost/ becomes /var/www/127.0.0.1
#
# Not used until version 0.93.17.2. This "feature" also breaks commonlog
# output rules, it prepends the interface number to each access_log line.
# You are expected to fix that problem with a postprocessing script.
#VirtualHost
# DocumentRoot: The root directory of the HTML documents.
# Comment out to disable server non user files.
DocumentRoot /www
# UserDir: The name of the directory which is appended onto a user's home
# directory if a ~user request is recieved.
#UserDir public_html
# DirectoryIndex: Name of the file to use as a pre-written HTML
# directory index. Please MAKE AND USE THESE FILES. On the
# fly creation of directory indexes can be _slow_.
# Comment out to always use DirectoryMaker
DirectoryIndex index.html
# DirectoryMaker: Name of program used to create a directory listing.
# Comment out to disable directory listings. If both this and
# DirectoryIndex are commented out, accessing a directory will give
# an error (though accessing files in the directory are still ok).
#DirectoryMaker /usr/lib/boa/boa_indexer
# DirectoryCache: If DirectoryIndex doesn't exist, and DirectoryMaker
# has been commented out, the the on-the-fly indexing of Boa can be used
# to generate indexes of directories. Be warned that the output is
# extremely minimal and can cause delays when slow disks are used.
# Note: The DirectoryCache must be writable by the same user/group that
# Boa runs as.
# DirectoryCache /var/spool/boa/dircache
# KeepAliveMax: Number of KeepAlive requests to allow per connection
# Comment out, or set to 0 to disable keepalive processing
KeepAliveMax 1000
# KeepAliveTimeout: seconds to wait before keepalive connection times out
KeepAliveTimeout 10
# MimeTypes: This is the file that is used to generate mime type pairs
# and Content-Type fields for boa.
# Set to /dev/null if you do not want to load a mime types file.
# Do *not* comment out (better use AddType!)
MimeTypes /etc/mime.types
# DefaultType: MIME type used if the file extension is unknown, or there
# is no file extension.
DefaultType text/plain
# CGIPath: The value of the $PATH environment variable given to CGI progs.
CGIPath /bin
# SinglePostLimit: The maximum allowable number of bytes in
# a single POST. Default is normally 1MB.
# AddType: adds types without editing mime.types
# Example: AddType type extension [extension ...]
# Uncomment the next line if you want .cgi files to execute from anywhere
AddType application/x-httpd-cgi cgi
# Redirect, Alias, and ScriptAlias all have the same semantics -- they
# match the beginning of a request and take appropriate action. Use
# Redirect for other servers, Alias for the same server, and ScriptAlias
# to enable directories for script execution.
# Redirect allows you to tell clients about documents which used to exist in
# your server's namespace, but do not anymore. This allows you to tell the
# clients where to look for the relocated document.
# Example: Redirect /bar http://elsewhere/feh/bar
# Aliases: Aliases one path to another.
# Example: Alias /path1/bar /path2/foo
#Alias /doc /usr/doc
# ScriptAlias: Maps a virtual path to a directory for serving scripts
# Example: ScriptAlias /htbin/ /www/htbin/
#ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/
ScriptAlias /cgi-bin/ /www/cgi-bin/
helloworld.c的代码，经过交叉编译后生成helloworld.cgi：
#include<stdio.h>
#include<stdlib.h>
int main()
{
int i;
printf("Content-type: text/html\n\n");
printf("<html>\n");
printf("<head><title>CGI Output</title></head>\n");
printf("<body>\n");
for(i=0;i<5;i++)
{
printf("<h1>Hello,world.</h1>\n");
}
printf("<body>\n");
printf("</html>\n");
exit(0);
