http-kit authorization with api-key

Wed, 07 Apr 2021 11:07:39 +0000

I need to make an API call with http-kit in Clojure where it uses API-Key as authorization. That is, in Postman, you would usually have the option to add an api-key, api-value and the option to add it to header or query-params.

I know the following would be the way to go in case of basic-auth:

{:url "<api-url>"
 :method :post
 :headers {"Content-Type" "application/json"}
 :basic-auth [<username> <password>]
 :body <body>)}

But a similar variation isn't working with api-key version. So far, I have tried:

{:basic-auth [<api-key> <api-value>]}

{:query-params {<api-key> <api-value>}}

{:query-params {:key <api-key>, :value <api-value>}}

{:headers {"Content-Type" "application/json", 
                    <api-key> <api-value>}

{:api-key [<api-key> <api-value>]}

{:api-key {<api-key> <api-value>}

and other variations, but it doesn't seem to be working.

Note:
- The authorization works on postman but I couldn't test the full api call there because the body is too long and too complex to copy, and the authorization isn't working from the application.
- I keep getting a 401 error with all these different combinations, and some give typeerrors depending on where in the request they're placed.
- The documentation isn't really useful. Here is the link.

REST API response body is not a string?

Sat, 20 Feb 2021 08:42:46 +0000

It's been a while since I've written Clojure, so I am rusty.

Basically, I'm trying to write code which does an HTTP GET on a REST API and converts that JSON array of objects into clojure data (list of Maps?). The JSON data looks like this:

[
    {
        "id": 1,
        "category": "technical",
        "asin": "0131103628",
        "title": "C Programming Language, 2nd Edition",
        "publication_date": "1988-04-01T00:00:00Z",
        "review": "The C book.",
        "created_at": "2020-03-06T20:48:00Z"
    },
    {
        "id": 2,
        "category": "technical",
        "asin": "0387966080",
        "title": "The Science of Fractal Images",
        "publication_date": "1988-07-19T00:00:00Z",
        "review": "The book on fractal algorithms.  Sadly, no longer in print.  I had to search high and low for a used copied.",
        "created_at": "2020-03-06T20:48:00Z"
    },
    // etc..
]

I'm using http-kit (I've also tried clj-http) to call the REST API and return the body. Later, I try converting the body to Clojure data. I've tried using both org.clojure/data.json and cheshire. However, I don't belive the data is being converted correctly.

(defn get-books-body
  []
  (:body @(client/get books-url api-options)))

(defn get-books
  []
  (parse-string get-books-body true))

When I try to display the type of the body, it shows up as an address instead of a string:

clojure-json-test.core=> (type get-books-body)
clojure_json_test.core$get_books_body

And I cannot look at the first record, after converting from JSON:

clojure-json-test.core=> (first get-books)
Execution error (IllegalArgumentException) at clojure-json-test.core/eval3169 (form-      init15378865171954877190.clj:1).
Don't know how to create ISeq from: clojure_json_test.core$get_books

Any idea what I am doing wrong?
