Having trouble escaping quotes and braces
CurlEscapingCommand PromptQuotesCurly BracesCurl Problem Overview
I am trying to execute the following line in Command Prompt:
curl -X POST -d '{ "method" : "account_info", "params" : [ { "account" : "rHb9CJAWyB4rj91VRWn96DkukG4bwdtyTh"} ] }' http://s1.ripple.com:51234

unable to parse request
I am on Windows, and the error has to do with quotes, braces, and globbing. I tried escaping quotes by preceding them with a backslash, with no luck.
Curl Solutions
Solution 1 - Curl
Do not use single quotes. Escape any double quotes within the string with a \.
curl -X POST -d "{ \"method\" : \"account_info\", \"params\" : [ { \"account\" : \"rHb9CJAWyB4rj91VRWn96DkukG4bwdtyTh\"} ] }" http://s1.ripple.com:51234
Window's command.exe doesn't seem to support single quotes. PowerShell does, but there are still some problems when using them, so the best solution is to not use them at all.
Solution 2 - Curl
You can use curl -g to turn off globbing:
curl -g -X POST -d '{ "method" : "account_info", "params" : [ { "account" : "rHb9CJAWyB4rj91VRWn96DkukG4bwdtyTh"} ] }' http://s1.ripple.com:51234
Easier than escaping all those brackets.
Solution 3 - Curl
Try the basic one to post something.
curl -X POST --data '{"username":"username", "password":"password"}' --header "Content-Type:application/json" http://127.0.0.1:8000/your_url/
Solution 4 - Curl
For windows users: you can download git bash for running the below curl command.
curl http://localhost:8080/subpage --include --header "Content-Type: application/json" --request "POST" --data '{"variable": "value"}
Solution 5 - Curl
In the above responses, it is important to note that data are specified in JSON format, which should require to specify --header as Alok's answer.
It is also possible to define it in "url" format like this:
curl -X POST --data "method=account_info¶ms=[…]" http://s1.ripple.com:51234
and avoid specifying --header "Content-Type…"
