为什么这段代码给我无法识别的错误

Question

**Curl 命令不起作用并生成无法识别的错误 **

喜欢

curl: (3) URL rejected: Bad hostname

'-h' is not recognized as an internal or external command, operable program or batch file.

`'-d' 不被识别为内部或外部命令， 可运行的程序或批处理文件。

curl -X POST "https://accounts.spotify.com/api/token" \
     -h "Content-Type: application/x-www-form-urlencoded" \
     -d "grant_type=client_credentials&client_id=xxxxxxxxxxxx&client_secret=xxxxxxxxx"

`

我正在尝试在命令提示符中使用 Spotify api 并希望解决无法识别的错误

-h 是获取命令帮助信息的开关

$ curl -h
Usage: curl [options...] <URL>
 -d, --data <data>          HTTP POST data
 -f, --fail                 Fail fast with no output on HTTP errors
 -h, --help <category>      Get help for commands
 -i, --include              Include protocol response headers in the output
 -o, --output <file>        Write to file instead of stdout
 -O, --remote-name          Write output to a file named as the remote file
 -s, --silent               Silent mode
 -T, --upload-file <file>   Transfer local FILE to destination
 -u, --user <user:password> Server user and password
 -A, --user-agent <name>    Send User-Agent <name> to server
 -v, --verbose              Make the operation more talkative
 -V, --version              Show version number and quit

This is not the full help, this menu is stripped into categories.
Use "--help category" to get an overview of all categories.
For all options use the manual or "--help all".

-h 需要一个类别作为子参数

就我而言，我收到此错误

Invalid category provided...

所以你正在尝试使用curl不支持的东西。但你得到的错误取决于分布。

应该是-H而不是-h

curl -X POST "https://accounts.spotify.com/api/token" \
     -H "Content-Type: application/x-www-form-urlencoded" \
     -d "grant_type=client_credentials&client_id=xxxxxxxxxxxx&client_secret=xxxxxxxxx"
