Ruby POST request with JSON body -


i trying write post request in ruby api published via microsoft machine learning studio. returning error 400 following:

require 'unirest' require 'json'  uri = "https://ussouthcentral.services.azureml.net/workspaces/a0e65d42d21c423fa4027d98f6ad364f/services/0d797f1b26d4410cae35c50d25d1c7cd/execute?api-version=2.0&details=true" apikey = "some api key" params = {some json body} response = unirest.post(uri, headers: {"content_length" =>"235", "content-type" => "application/json", "authorization" => "bearer" + " " + apikey}, parameters: params)

for life of me cannot figure out how structure request. according documentation:

authorization:bearer abc123

required. pass api key here. obtain key publisher of api.

content-length

required. length of content body.

content-type:application/json

required if request body sent in json format.

accept: application/json

optional. use header receive response in json format.

i'm not great ruby text editor doesn't seem when use : between header , value instead of =>.

the body need include in request if shown in documentation:

{   "inputs": {"input1": {       "columnnames": [         "case number",         "case type",         "address",         "description",         "case group",         "date case created",         "last inspection date",         "last inspection result",         "status",         "permit , complaint status url",         "latitude",         "longitude",         "location"       ],       "values": [         [           "0",           "value",           "value",           "value",           "value",           "",           "",           "value",           "value",           "value",           "0",           "0",           "value"         ],         [           "0",           "value",           "value",           "value",           "value",           "",           "",           "value",           "value",           "value",           "0",           "0",           "value"         ]       ]     }   },   "globalparameters": {}}

everytime throw in editor , try run script kinds of errors. unexpected , expecting end, etc...

can please explain i'm doing wrong here?

try .to_json after hash. i.e. {"content_length" =>"235"}.to_json , params.to_json
