I am running an Apache Solr tutorial from here:
Solr is running and I can run queries in a web browser.
The tutorial mentions cURL which I am unfamiliar with.
I have unzipped CURL to C:\Curl and included Curl in the PATH environment variable: C:\Curl\curl-7.63.0-win64-mingw\bin
I am getting an error when running the Command below in a Windows command prompt. I have googled to try and find a resolution to no avail:
Code below:
C:\Curl\curl-7.63.0-win64-mingw\bin>curl -X POST -H 'Content-type:application/json' --data-binary '{"add-field": {"name":"name", "type":"text_general", "multiValued":false, "stored":true}}' generates the following error:
curl: (3) unmatched brace in URL position 1: {name:name, ^ curl: (3) URL using bad/illegal format or missing URL curl: (3) URL using bad/illegal format or missing URL curl: (3) unmatched close brace/bracket in URL position 12: stored:true}}' ^ { "responseHeader":{ "status":400, "QTime":1}, "error":{ "metadata":[ "error-class","org.apache.solr.common.SolrException", "root-error-class","org.apache.solr.common.SolrException"], "msg":"no stream", "code":400}} I tried adding a -g to turn off globbing.
curl -g -X POST -H 'Content-type:application/json' --data-binary '{"add-field": {"name":"name", "type":"text_general", "multiValued":false, "stored":true}}' This generated an almost identical error:
C:\Curl\curl-7.63.0-win64-mingw\bin>curl -g -X POST -H 'Content-type:application/json' --data-binary '{"add-field": {"name":"name", "type":"text_general", "multiValued":false, "stored":true}}' curl: (3) URL using bad/illegal format or missing URL curl: (3) URL using bad/illegal format or missing URL curl: (3) URL using bad/illegal format or missing URL curl: (3) URL using bad/illegal format or missing URL { "responseHeader":{ "status":400, "QTime":1}, "error":{ "metadata":[ "error-class","org.apache.solr.common.SolrException", "root-error-class","org.apache.solr.common.SolrException"], "msg":"no stream", "code":400}} I then tried removing the single quotes and escaping the double quotes, but then got the below error:

I know there are a lot of similar Q&A's on SO regarding this issue but they are not quite the same and none of the solutions I have tried resolve my issue.

I replaced the single quotes with double quote and escaped the double quotes inside the curly braces with a backslash and it has worked.
I went from this:
curl --X POST -H 'Content-type:application/json' --data-binary '{"add-field": {"name":"name", "type":"text_general", "multiValued":false, "stored":true}}' to this:
curl --X POST -H "Content-type:application/json" --data-binary "{\"add-field\": {\"name\":\"name\", \"type\":\"text_general\", \"multiValued\":false, \"stored\":true}}" Thank you everybody for your collective answers. I am sure there are some possible positives to adding the JSON to a separate file but i wanted to avoid the creation of additional files.
The Windows command prompt doesn't support single quotes. It's a problem because cURL statements use single quotes to specify JSON data.
To fix the problem, save the JSON in a separate file (e.g. add-field.txt) and import it into the cURL statement, so later you could run it like this:
curl -X POST -H 'Content-type:application/json' --data-binary @add-field.txt I would go another route. If you install Microsoft's wonderfool tool WSL. You will be able to run all those commands as is, as you will be running inside a linux system. It will be a big time saver eventually.
Gitbash solved it for me. WSL was crashing for a reason I ignore at the moment.
I found that this worked for me:
curl -X POST -H 'Content-type:application/json' --data "$DATA" Where $DATA is a shell varible containing JSON data and is enclosed in doub;e-quotes. This was in a Linux environment where I was having the same issue.
