Set headers in a groovy post request - post

Question

I need to set a header in a post request: ["Authorization": request.token]
I have tried with wslite and with groovyx.net.http.HTTPBuilder but I always get a 401-Not authorized which means that I do cannot set the header right.
I have also thought of logging my request to debug it but I am not able to do that either.
With wslite this is what I do
Map<String, String> headers = new HashMap<String, String>(["Authorization": request.token])
TreeMap responseMap
def body = [amount: request.amount]
log.info(body)
try {
Response response = getRestClient().post(path: url, headers: headers) {
json body
}
responseMap = parseResponse(response)
} catch (RESTClientException e) {
log.error("Exception !: ${e.message}")
}
Regarding the groovyx.net.http.HTTPBuilder, I am reading this example https://github.com/jgritman/httpbuilder/wiki/POST-Examples but I do not see any header setting...
Can you please give me some advice on that?

Answer 1

I'm surprised that specifying the headers map in the post() method itself isn't working. However, here is how I've done this kind of thing in the past.
def username = ...
def password = ...
def questionId = ...
def responseText = ...
def client = new RestClient('https://myhost:1234/api/')
client.headers['Authorization'] = "Basic ${"$username:$password".bytes.encodeBase64()}"
def response = client.post(
path: "/question/$questionId/response/",
body: [text: responseText],
contentType: MediaType.APPLICATION_JSON_VALUE
)
...
Hope this helps.

Here is the method that uses Apache HTTPBuilder and that worked for me:
String encodedTokenString = "Basic " + base64EncodedCredentials
// build HTTP POST
def post = new HttpPost(bcTokenUrlString)
post.addHeader("Content-Type", "application/x-www-form-urlencoded")
post.addHeader("Authorization", encodedTokenString)
// execute
def client = HttpClientBuilder.create().build()
def response = client.execute(post)
def bufferedReader = new BufferedReader(new InputStreamReader(response.getEntity().getContent()))
def authResponse = new JsonSlurper().parseText(bufferedReader.getText())
