express - Expressjs Invalid JSON when data is just a string -

-

searching has proven difficult, since people asking have object have serialized (incorrectly).

i sending string. not object, string. here request right before it's fired off. json.parse can handle payload fine. string double quoted, per the spec.

enter image description here

express js gives simple error: error: invalid json. need send string payload?

by default express.bodyparser(), based on connect json middleware operates in strict mode. strict mode parse objects or arrays, sticking strictly json spec.

json built on 2 structures:

a collection of name/value pairs. in various languages, realized object, record, struct, dictionary, hash table, keyed list, or associative array.

an ordered list of values. in languages, realized array, vector, list, or sequence.

if want non-strict version, can optionally using option use json.parse, ok parsing string representation of raw json value 'true', '"stackoverflow"', '42', , on.

app.use(connect.bodyparser({strict: false}));
