Dealing with Expressjs error messages: When sending data that is strictly a string,

It has been quite challenging to find information on this topic, as most inquiries involve incorrectly serialized objects.

I am attempting to send a string, not an object. Here is the request right before it is sent off. The payload can be properly handled by JSON.parse, as the string is correctly double quoted according to the specifications.

Express JS simply returns the error message: Error: invalid json. What steps should I take in order to successfully send just a string as a payload?

Answer №1

By default, the express.bodyParser() function, which utilizes the connect json middleware, operates in a mode known as 'strict'. In strict mode, only objects or arrays are parsed, adhering strictly to the JSON specifications.

JSON is comprised of two main structures:

1. A collection of name/value pairs, represented in various programming languages as an object, record, struct, dictionary, hash table, keyed list, or associative array.

2. An ordered list of values, commonly represented as an array, vector, list, or sequence in most programming languages.

If you desire a non-strict version, you have the option to enable that by specifying an option that will utilize JSON.parse, allowing for parsing of string representations of raw JSON values like 'true', '"stackoverflow"', '42', and so on.

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