-u, --user <user:password> Specify the user name and password to use for server authentication. Overrides -n, --netrc and --netrc-optional. If you simply specify the user name, curl will prompt for a password. The user name and passwords are split up on the first colon, which makes it impossible to use a colon in the user name with this option. The password can, still. When using Kerberos V5 with a Windows based server you should include the Windows domain name in the user name, in order for the server to succesfully obtain a Kerberos Ticket. If you don't then the initial authentication handshake may fail. When using NTLM, the user name can be specified simply as the user name, without the domain, if there is a single domain and forest in your setup for example. To specify the domain name use either Down-Level Logon Name or UPN (User Principal Name) formats. For example, EXAMPLE\user and user@example.com respectively. If you use a Windows SSPI-enabled curl binary and perform Kerberos V5, Negotiate, NTLM or Digest authentication then you can tell curl to select the user name and password from your environment by specifying a single colon with this option: "-u :". If this option is used several times, the last one will be used.

注意，你不需要——basic标志，因为它是默认的。

弄清楚授权头应该是什么样子的最简单的方法可能是首先运行curl和-u(或将凭证放在URL中)和-v，输出将显示请求头:

$ curl -v -u 'apiuser:apipwd' ... http://apigilityhw.sandbox.loc/status

# OR putting the credentials in the URL: 

$ curl -v ... http://apiuser:apipwd@apigilityhw.sandbox.loc/status
    
# copy and paste the "Authorization" header from the output:
    
$ curl -H 'Authorization: Basic YWRtaW46YXBpcHdk' ... http://apigilityhw.sandbox.loc/status

作为标题

AUTH=$(echo -ne "$BASIC_AUTH_USER:$BASIC_AUTH_PASSWORD" | base64 --wrap 0)

curl \
  --header "Content-Type: application/json" \
  --header "Authorization: Basic $AUTH" \
  --request POST \
  --data  '{"key1":"value1", "key2":"value2"}' \
