我找到了 很多关于如何在 cURL中使用简单的POST命令的例子，但是我没有找到如何发送完整的 HTTP POST命令的例子，这些命令中包含了
s=1&r=33） 我找到的都是：
echo "this is body" | curl -d "ss=ss&qq=11" http://localhost/
那不行，它把 HTTP参数作为body发送。
HTTP “参数 "是URL的一部分。
"http://localhost/?name=value&othername=othervalue"
基本认证有一个单独的选项，没有必要创建一个自定义头。
-u "user:password"
POST "body "可以通过--data(application/x-www-form-urlencoded)或--form(multipart/form-data)发送：
-F "foo=bar" # 'foo' value is 'bar'
-F "foo=<foovalue.txt" # the specified file is sent as plain text input
-F "foo=@foovalue.txt" # the specified file is sent as an attachment
-d "foo=bar"
-d "foo=<foovalue.txt"
-d "foo=@foovalue.txt"
-d "@entirebody.txt" # the specified file is used as the POST body
--data-binary "@binarybody.jpg"
所以，总结一下：
curl -d "this is body" -u "user:pass" "http://localhost/?ss=ss&qq=11"
``` POST "body
名气不够，无法评论，所以留下这个作为答案，希望对大家有所帮助。
curl -L -v --post301 --post302 -i -X PUT -T "${aclfile}" \
-H "Date: ${dateValue}" \
-H "Content-Type: ${contentType}" \
-H "Authorization: AWS ${s3Key}:${signature}" \
${host}:${port}${resource}
这是我在S3 bucket acl put操作中使用的方法。头文件在-H中，正文是一个xml文件，在-T后面的${aclfile}中。你可以从输出中看到这一点。

如果url参数包含特殊符号，比如 “+"，则对其中的每个参数（包含特殊符号）使用–data-urlencode。
curl -G -H "Accept:..." -H "..." --data-urlencode "beginTime=${time}+${zone}" --data-urlencode "endTime=${time}+${zone}" "${url}"
