如何使用cURL发送带有正文，标头和HTTP参数的POST？

我找到了很多有关如何在cURL中使用简单POST命令的示例，但没有找到有关如何发送完整的HTTP POST命令的示例，其中包括：

• 标头（基本身份验证）
• HTTP参数（s=1&r=33）
• 正文数据，一些XML字符串

我发现的是：

echo "this is body" | curl -d "ss=ss&qq=11" http://localhost/

那是行不通的，它将HTTP参数作为正文发送。

声誉不足，无法发表评论，因此请留下答案以希望有所帮助。

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}

这就是我用于S3存储桶acl put操作的内容。标题位于-H中，而作为XML文件的主体位于-T之后的$ {aclfile}中。您可以从输出中看到：

/aaa/?acl

如果url参数包含特殊符号（例如“ +”），请对每个参数（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}"

HTTP“参数”是URL的一部分：

"http://localhost/?name=value&othername=othervalue"

基本身份验证有一个单独的选项，无需创建自定义标头：

-u "user:password"

POST“正文”可以通过--data（for application/x-www-form-urlencoded）或--form（for 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"

因此，总结一下：

curl -d "this is body" -u "user:pass" "http://localhost/?ss=ss&qq=11"
