Sails: Error at POST, PUT

[ytzvan]

Hello, I got the following error when try to POST content via postman using Sails Blueprints. GET and DELETE methods works fine.

So when I try to update or create a model, I got the following error:

error: Unable to parse HTTP body- error occurred :: 'Error: invalid json\n at parse (/Users/Ytzvan/myapp/node_modules/sails/node_modules/skipper/node_modules/connect/node_modules/body-parser/lib/types/json.js:62:15)\n at /Users/Ytzvan/myapp/node_modules/sails/node_modules/skipper/node_modules/connect/node_modules/body-parser/lib/read.js:91:18\n at IncomingMessage.onEnd (/Users/Ytzvan/myapp/node_modules/sails/node_modules/skipper/node_modules/connect/node_modules/body-parser/node_modules/raw-body/index.js:136:7)\n at IncomingMessage.g (events.js:180:16)\n at IncomingMessage.emit (events.js:92:17)\n at _stream_readable.js:943:16\n at process._tickDomainCallback (node.js:463:13)'

Thanks.

Sounds like you are sending invalid JSON data in the body. Paste an example of what data you are sending.

Using postman form-data the result is the previous error, but if I send a raw json like this:

{
    "name": "Beach Trip",
    "description": "Beach Trip",
    "city": "Beach Trip",
    "country": "Panama",
    "min": null,
    "max": null,
    "departure": null,
    "arrival": null,
    "price": null,
    "duration": null,
    "transportation": null,
    "food": null,
    "pictures": null,
    "insurance": null,
    "category": null,
    "location": "undefined, undefined",
    "latitude": null,
    "longitude": null
}

Works fine.

Sounds like you are sending Content-Type headers with application/json for your form encoded data. That would explain why it works with json data.

For using form data try setting your Content-Type headers to application/x-www-form-urlencoded.

Hi All,

My request looks like:
{"identifier":\,"password":}

I need to write validation for this, for this i wrote "reqbodyvalidation" policy something like this and applied to the method.

function isValidJson(json) {
try {
JSON.parse(json);
return true;
} catch (e) {
return false;
}
}

if (!req.body && _.isEmpty(req.body)) {
    return res.status(400).send({error:'Req Body should not be empty'});
}else{
    if(isValidJson(req.body)){
        next();
    }else{
         return res.status(400).send({error:'Not a valid JSON'});
    }
}

and Policies:
userLogin: ['reqBodyValidation','passport','ModelPolicy', 'AuditPolicy']

Can anyone guide me to solve this as i feel it is not getting upto this place prior to this event. its throwing error:
error: Unable to parse HTTP body- error occurred :: 'SyntaxError: Unexpected token \n at Object.parse (native)\n at parse ............................

Thanks so much for your help!

@ayyappaappana you will need to handle this error within the http.js file. See https://github.com/balderdashy/sails-docs/blob/1.0/reference/sails.config/sails.config.http.md#customizing-the-body-parser for more information on configuring the default body parser, Skipper.
