HTTP stands for Hypertext Transfer Protocol. It is rules for data communication in WWW(Web Wide Web).
Components of a request
In order to make a http request, we need to at least specify:
- Request method — what is the type of request we are making.
- URI — which resource to apply the request, including protocol and host name.
- Header — additional information about the request, client to the server.
Use netcat to create mock server
To checkout the usage of netcat:
man nc
Create a mock server on port 1000:
nc -l 1000
-l stands for listen, tells netcat to listen to the specific port number you provided.
Use cURL to make a http request
To checkout the usage of cCRL:
curl --help
To make a request:
curl localhost:1000 -H multipart/form-data -F name=Daisy
- -X specify the request method
- -H specifies the request header
- -F specifics the form data
Once your request is send, your will receive request detail in your mock service like so:
POST / HTTP/1.1Host: localhost:1000User-Agent: curl/7.64.1Accept: */*Content-Length: 144Content-Type: multipart/form-data; boundary=------------------------5438f201a4f68776--------------------------5438f201a4f68776Content-Disposition: form-data; name="name"Daisy--------------------------5438f201a4f68776--
