Replace and add json within another json - json

Question

I have a Main json file.
{
"swagger": "2.0",
"paths": {
"/agents/delta": {
"get": {
"description": "lorem ipsum doram",
"operationId": "getagentdelta",
"summary": "GetAgentDelta",
"tags": [
"Agents"
],
"parameters": [
{
"name": "since",
"in": "query",
"description": "Format - date-time (as date-time in RFC3339). The time from which you need changes from. You should use the format emitted by Date's toJSON method (for example, 2017-04-23T18:25:43.511Z). If a timestamp older than a week is passed, a business rule violation will be thrown which will require the client to change the from date. As a best-practice, for a subsequent call to this method, send the timestamp when you <b>started</b> the previous delta call (instead of when you completed processing the response or the max of the lastUpdateOn timestamps of the returned records). This will ensure that you do not miss any changes that occurred while you are processing the response from this method",
"required": true,
"type": "string"
}
]
}
}
}
}
And I have a smaller json file.
{
"name": "Authorization",
"description": "This parameter represents the Authorization token obtained from the OKTA Authorization server. It is the Bearer token provided to authorize the consumer. Usage Authorization : Bearer token",
"in": "header",
"required": true,
"type": "string"
}
Now I need to add the contents of the smaller json file into the Main.Json file in the parameters array.
I tried the below command
cat test.json | jq --argfile sub Sub.json '.paths./agents/delta.get.parameters[ ] += $sub.{}' > test1.json
But I get the below error:
jq: error: syntax error, unexpected '{', expecting FORMAT or QQSTRING_START (Unix shell quoting issues?) at <top-level>, line 1:
.paths += $sub.{}
jq: 1 compile error
cat: write error: Broken pipe
I tried this command.
cat test.json | jq '.paths./agents/delta.get.parameters[ ] | = (.+ [{ "name": "Authorization", "description": "This parameter represents the Authorization token obtained from the OKTA Authorization server. It is the Bearer token provided to authorize the consumer. Usage Authorization : Bearer token", "in": "header", "required": true, "type": "string" }] )' > test1.json
And I get no error and no output either. How do I get around this?
I would have to add the contents of the smaller json file directly first. And then at a later stage, search if it already had name: Authorization and it's other parameters, and then remove and replace the whole name: Authorization piece with the actual contents of the smaller.json, under each path that starts with '/xx/yyy'.
Edited to add:
For the last part of the question, I could not use the walk function, since I have jq 1.5 and since am using the bash task within Azure DevOps, I can't update the jq installation file with the walk function.
Meanwhile I found the use of something similar to wildcard in jq, and was wondering why I can't use it in this way.
jq --slurpfile newval auth.json '.paths | .. | objects | .get.parameters += $newval' test.json > test1.json
Can anyone please point out the issue in the above command? It did not work, and am not sure why..

Answer 1

You want --slurpfile, and you need to escape /agents/delta part of the path with quotes:
$ jq --slurpfile newval insert.json '.paths."/agents/delta".get.parameters += $newval' main.json
{
"swagger": "2.0",
"paths": {
"/agents/delta": {
"get": {
"description": "lorem ipsum doram",
"operationId": "getagentdelta",
"summary": "GetAgentDelta",
"tags": [
"Agents"
],
"parameters": [
{
"name": "since",
"in": "query",
"description": "Format - date-time (as date-time in RFC3339). The time from which you need changes from. You should use the format emitted by Date's toJSON method (for example, 2017-04-23T18:25:43.511Z). If a timestamp older than a week is passed, a business rule violation will be thrown which will require the client to change the from date. As a best-practice, for a subsequent call to this method, send the timestamp when you <b>started</b> the previous delta call (instead of when you completed processing the response or the max of the lastUpdateOn timestamps of the returned records).

"required": true,
"type": "string"
},
{
"name": "Authorization",
"description": "This parameter represents the Authorization token obtained from the OKTA Authorization server. It is the Bearer token provided to authorize the consumer. Usage Authorization : Bearer token",
"in": "header",
"required": true,
"type": "string"
}
]
}
}
}
}
And here's one that first removes any existing Authorization objects from the parameters before inserting the new one into every parameters array, and doesn't depend on an the exact path:
jq --slurpfile newval add.json '.paths |= walk(
if type == "object" and has("parameters") then
.parameters |= map(select(.name != "Authorization")) + $newval
else
.
end)' main.json
