How to send a header using a HTTP request through a curl call?

Question

I wish to send a header to my Apache server on a Linux box. How can I achieve this via a curl call?

Answer 1

In anaconda envirement through windows the commands should be: GET, for ex:

curl.exe http://127.0.0.1:5000/books 

Post or Patch the data for ex:

curl.exe http://127.0.0.1:5000/books/8 -X PATCH -H "Content-Type: application/json" -d '{\"rating\":\"2\"}' 

PS: Add backslash for json data to avoid this type of error => Failed to decode JSON object: Expecting value: line 1 column 1 (char 0)

and use curl.exe instead of curl only to avoid this problem:

Invoke-WebRequest : Cannot bind parameter 'Headers'. Cannot convert the "Content-Type: application/json" value of type
"System.String" to type "System.Collections.IDictionary".
