[dsears]

Similar issue: plus signs getting turned into spaces:

$ curl -i -X POST -d '{"jsonrpc": "2.0", "method": "echo", "params": ["hello+world"], "id": "1"}' http://localhost:5000/api
HTTP/1.0 200 OK
Content-Type: application/json
Content-Length: 64
Server: Werkzeug/0.10.4 Python/2.7.5
Date: Fri, 10 Jul 2015 20:18:51 GMT

{
  "id": "1", 
  "jsonrpc": "2.0", 
  "result": "hello world"
}

@dsears,

I'm planning fixed in next weekend this and others issues and generate version.

Thank you.

Hello,

Try using the header: Contenty-Type: application/json.

When there is defined a content type, Flask using Request.form[1]
to provide the POST parameters, and sets when it uses the Request.data[2]
for this purpose.

The means "safe" pick up via Request.form parameters is:

list(request.form.to_dict().keys())[0]

and the text is encoded and failure to capture the parameters.

For example:

@jsonrpc.method('App.hello')
def hello(name):
    return u'Hello {0}'.format(name)

$ curl -i -X POST -H "Content-Type: application/json" \
   -d '{"jsonrpc": "2.0", "method": "App.hello", "params": ["Flask=JSONRPC"], "id": "1"}' \
   http://localhost:5000/api
HTTP/1.0 200 OK
Content-Type: application/json
Content-Length: 72
Server: Werkzeug/0.10.4 Python/2.7.10

{
  "id": "1", 
  "jsonrpc": "2.0", 
  "result": "Hello Flask=JSONRPC"
}

$ curl -i -X POST -H "Content-Type: application/json" \
   -d '{"jsonrpc": "2.0", "method": "App.hello", "params": ["Flask+JSONRPC"], "id": "1"}' \
   http://localhost:5000/api
HTTP/1.0 200 OK
Content-Type: application/json
Content-Length: 72
Server: Werkzeug/0.10.4 Python/2.7.10
Date: Wed, 29 Jul 2015 14:07:43 GMT

{
  "id": "1", 
  "jsonrpc": "2.0", 
  "result": "Hello Flask+JSONRPC"
}

Thank you.
