Creating an index with REST API - apache

Question

I'm trying to create an index within a set under a specific namespace, but am unsure how to do it.
My resources have this as an HTTP example:
POST /example/v1/index/{namespace}/{set}/{indexName}
and for an example input:
{
"fields": [
{ "indexField": "firstName", "indexReverseOrder": true },
{ "indexField": "lastName" }
],
"options": {
"isUnique": true
}
}
this consumes
application/json;charset=UTF-8
but when I write this out as
curl -X POST exampleurl.com/example/v1/index/example_namespace/example_set/example
set -d " {
"fields": [
{ "indexField": "firstName", "indexReverseOrder": true },
{ "indexField": "lastName" }
],
"options": {
"isUnique": true
} }" -H "Content-type : application/json;charset=UTF-8"
I get the following HTTP status code
HTTP/1.1 415 Unsupported Media Type
Can anyone explain to me what's going on and how I might fix this? Also, let me know if you don't have enough information about the API to understand it, thanks!
EDIT:
As some sort of a reference, for this API when I create a set in a namespace I do:
curl -X POST http://exampleurl.com/example/v1/store/example_namespace -d "example_set" -H "Content-type: application/json;charset=UTF-8"
and this is successful. I thought indexes would be similar to this, but apparently not.

Answer 1

The error is due to the bash shell misinterpreting the double quotes before the json
curl -X POST exampleurl.com/example/v1/index/example_namespace/example_set/example
set -d " {
"fields": [
{ "indexField": "firstName", "indexReverseOrder": true },
{ "indexField": "lastName" }
],
"options": {
"isUnique": true
} }" -H "Content-type : application/json;charset=UTF-8"
should be:
curl -X POST exampleurl.com/example/v1/index/example_namespace/example_set/example
set -d ' {
"fields": [
{ "indexField": "firstName", "indexReverseOrder": true },
{ "indexField": "lastName" }
],
"options": {
"isUnique": true
} }' -H "Content-type : application/json;charset=UTF-8"
The difference is the single quotes encapsulating the json. The bash shell will give an error in trying to execute the command.

You have a typo in your media type:
application/json;charset=UTF=8
Should be:
application/json;charset=UTF-8
