curl 常用参数备忘
| 参数名 | 作用 | 备忘 |
|---|---|---|
I | 只显示文档信息 | 等价于 --head |
i | 在输出中显示协议头 | Include protocol headers in the output (H/F) |
-k, --insecure | 忽略证书问题等安全校验 | |
-v, --verbose | 显示请求过程详细信息 | Useful for debugging and seeing what's going on "under the hood". |
| -F, --form | 模拟提交一个表单 | (HTTP SMTP IMAP) For HTTP protocol family, this lets curl emulate a filled-in form in which a user has pressed the submit button. This causes curl to POST data using the Content-Type multipart/form-data according to RFC 2388. |
常用命令:
上传文件
curl --form upload=@/path/to/filename.xxx \
--form formParamName1=value \
--form formParamName2=value \
http://localhost:8080/upload
注: 上面的命令实际是生成一个POST FORM参数. 关键步骤是会生成一个表单参数: multipart/form-data
我们看一个如下的实例:
curl -v --form a=b www.baidu.com
* Trying 103.235.46.39...
* TCP_NODELAY set
* Connected to www.baidu.com (103.235.46.39) port 80 (#0)
> POST / HTTP/1.1
> Host: www.baidu.com
> User-Agent: curl/7.64.1
> Accept: */*
> Content-Length: 137
> Content-Type: multipart/form-data; boundary=------------------------e3141fd1210883ec
>
* We are completely uploaded and fine
< HTTP/1.1 302 Found
< Connection: keep-alive
< Content-Length: 17931
< Content-Type: text/html
< Date: Sat, 23 Apr 2022 10:05:37 GMT
< Etag: "54d9748e-460b"
< Server: bfe/1.0.8.18
<
也可以使用
-F参数进行简写.
curl -F 'paramA=valueA' -F 'filesName=@/path/to/file'
参数-g
可能的报错: # curl: (3) [globbing] bad range specification in column 107 错误。
# -g, --globoff
This option switches off the "URL globbing parser". When you set this option, you can specify URLs that contain the letters {}[] without having them
being interpreted by curl itself. Note that these letters are not normal legal URL contents but they should be encoded according to the URI standard.
# 释义: 选项开关 - 文件名扩展解析器. 当你设置了此标记的时候,你可以指定包含字母:{}和[]的URL. 这些字母不会被curl再次解析.
注意,这些字母不是正常的合法URL内容.
当你的url里面包含有一些特殊字符的时候,你又不想处理.这个时候可以用这个参数进行暂时处理. 正常的处理方法还是进行编码后使用. 比如下面这个是一个不好的实践:
curl -H "Host: xyks.yuanfudao.xxx" \
-H "Cookie: sid=99374083520958116; YFD_U=-6654511933970064481; wxsess=YOa1rlCiJyikgfoRyjQGpAgQENT8oDHNb3ElbtGe3eSnzDdiguHX0hALRV9LJI329dU8Smfy2/vQe86rjtIjzN164ZCOkHjy8IQA9tikA4Y=; userid=201703736; __sub_user_infos__=/24T7Ovgtuud9LSYuz4IE3TWmK65CT7S5el8cBskXKkjy969eCCcUWWQt0GmGR3SPPUIVPF8dMH/wQ8WHE+8Mw==; g_loc=vPeteFfrRL2jJ0VNIL3TWQ==; persistent=8ACna01r3yKDLPHqUrfb1j+reOFAIpXOCCC1PE2wIbdOBRQ0jIehzt+dDK9I0R1uECpgtFnmeCAE9QDgveglNQ==; sess=Gk5qkVX45GynE8blqtX3LwDTgsDp3WKFJP9oebNHoieid65fgfo2I1JdK1Rjl/UtmTo/MtxM6TrteIXnhXIYJ8L/NCYy31sNuLwSuhfcHHw=; g_sess=Gk5qkVX45GynE8blqtX3LwDTgsDp3WKFJP9oebNHoieid65fgfo2I1JdK1Rjl/UtmTo/MtxM6TrteIXnhXIYJ4kJ24Br6dONs3lH674UGxYLjBttPnfvFVLwR9r005dM" \
