Re: Problems with request.json_body

[Michael Merickel]

If you manually parse the json yourself using json.loads(request.body) what is the result? This is really all json_body does.

Hey guys,

I'm just trying to send a simple json to my callable view using this beneath. But when the method execution reach request.json_body I alway got an ValueError.

But it's funny because if I'd change request.json_body to request.body, que program prints the json string correctly. So, this is a bug?

Command :curl -v -H "Accept: application/json" -H "Content-type: application/json" -X POST -d '{"user":{"first_name":"firstname","last_name":"lastname"}}' http://localhost:6543/hello

This is my callable view:

@view_config(name='hello',renderer='string')

def hello(request):

print request.json_body

return 'OK'

When I sent a json using curl, the request_body is a string like these: '{user:johnny , email: joh...@foolish.com}'. 

But the correct format is '{"user":"johnny" , "email": "joh...@foolish.com"}'. This could be a curl's bug.

So, I've tried do this using jquery and worked for me:

$.ajax({ url:'http://localhost:6543/myurl,

        type:'post',

        data:JSON.stringify(mydata),

        contentType: 'application/json; charset=utf-8',

        dataType: 'json'

});

It's more likely a shell quoting bug:

$ echo {"hello": "world"}
{hello: world}

$ echo '{"hello": "world"}'
{"hello": "world"}
