How to use clj-http to post a request?

When I click the search button on this page, it sends a post request. I want to do the post via cli-http. How can I do that?

(def default-http-opts 
    {:socket-timeout 10000
     :conn-timeout 10000
     :insecure? true
     :throw-entire-message? false})

(clj-http/post initial-url default-http-opts)

can post a request but the problem is that I want to pass in some parameters. These parameters(the buttons selected) are default on the page.

They are:

AdvancedSearchForm:CourseOrSubjectSelection=ALL_ALL
AdvancedSearchForm:GraduateLevelSelection=ALL

AdvancedSearchForm:allStudyAreas=t

AdvancedSearchForm:departmentList=

AdvancedSearchForm:facultyList=

AdvancedSearchForm:keywords=

AdvancedSearchForm:level=ALL

AdvancedSearchForm:semester=ALL

oracle.adf.faces.FORM=AdvancedSearchForm

oracle.adf.faces.STATE_TOKEN=_id21519:_id21520

source=AdvancedSearchForm:searchButton

The key AdvancedSearchForm:semester contains ':', so I use string as a key like this "AdvancedSearchForm:semester", is it OK in clj-http?

I do it like this:

(spit (file "/tmp" "ts.html") 
    (:body (http/post initial-url 
        {:form-params {"AdvancedSearchForm:CourseOrSubjectSelection" "ALL_ALL",                          "AdvancedSearchForm:GraduateLevelSelection" "ALL"}})))`

Actually the page it returns is indeed "Results" but no courses are listed. only the template. I want to get all the course links which are only shown by manually click. Any help?

This is the image I screenshot from Tamper Data. It shows what happens after I click the Search button. Seems like client is redirected to searchresult.jsp. I use curl to imitate that. I do it like this

curl -D "form data..." https://handbook.unimelb.edu.au/faces/htdocs/user/search/AdvancedSearch.jsp

Then quickly run

curl https://handbook.unimelb.edu.au/faces/htdocs/user/search/SearchResults.jsp

No results contents are shown though the page is downloaded.

It looks like the server doesn't understand the parameters you send to it.

The escaping in use is the percent-encoding. Try to check out if it get in use by using the debug functionality avail in clj-https README.md:

;; print request info to *out*, including request body:
(client/post "http://example.org" {:debug true :debug-body true :body "..."})

or try to manually run the requests either with the curl command in a terminal or with the convenient Firefox restclient add-on.

From their GitHub page (https://github.com/dakrone/clj-http):

;; Send form params as a urlencoded body (POST or PUT)
(client/post "http//site.com" {:form-params {:foo "bar"}})
