error 500 when starting the interface

[spierluigi]

redmine 1.2.1

after having installed the plugin and enabled the REST interface, calling it with the very basic call (.../json_rpc_call.json?key=xxxx) it the system gives this error:

Rendering /usr/share/redmine/public/500.html (500 Internal Server Error)

It looks like some template is missing somewhere inside the ther installed plugins

Sorry, but your request is wrong. Plugin accepts only(!) POST requests. But you are right - I have to add some explanational error message for this case.

[spierluigi]

So, please, could you add to the read-me doc some example of syntax ? Thanks

[maxprokopiev]

You can find examples in README file. For example, very basic call looks like this: URL: http://your_redmine_server/json_rpc_call.json?key=you_api_key POST data: {"class": "Project", "method" : "find", "params" : ["project_id"]}

just replace server, key and project_id params with your own.

For sending POST requests I suggest using curl.

[spierluigi]

Good, but unfortunately I am quit enew to this matter.

From the Ubuntu prompt I entered this command line:

curl -F "class=project;method=find;params=" http://XX.XX.XX.XX/redmine/json_rpc_call.json?key=5b9cc482aec02b53991b2e9a6a43caf044cfb9e9

I get this error message: "{"error":"uninitialized constant JsonRpcCallController::JSON"}"

Then I entered the command as

curl -F "key=5b9cc482aec02b53991b2e9a6a43caf044cfb9e9;class=project;method=find;params=" http://XX.XX.XX.XX/redmine/json_rpc_call.json

No error, just the prompt. If there is an answer, where is ti ?
