# About
|
|
|
|
|
|
|
|
I needed something like Express.js's `body-parser` module, so I made it here. It fully supports JSON requests.
|
2016-04-17 03:11:33 +00:00
|
|
|
x-www-form-urlencoded fully supported, as well as query strings. You can also include arrays in your query,
|
2016-04-17 19:51:40 +00:00
|
|
|
in the same way you would for a PHP application. Full file upload support will also be present by the production 1.0.0 release.
|

|
|
|
|
|
|
|
A benefit of this is that primitive types are automatically deserialized correctly. As in, if you have a `hello=1.5` request, then
|
|
|
|
`body['hello']` will equal `1.5` and not `'1.5'`. A very semantic difference, yes, but it relieves stress in my head.
|
|
|
|
|
|
|
|
# Installation
|
|
|
|
|
|
|
|
To install Body Parser for your Dart project, simply add body_parser to your
|
|
|
|
pub dependencies.
|
|
|
|
|
|
|
|
dependencies:
|
|
|
|
body_parser: any
|
|
|
|
|
|
|
|
# Usage
|
|
|
|
|
|
|
|
Body Parser exposes a simple class called [BodyParseResult].
|
|
|
|
You can easily parse the query string and request body for a request by calling `Future<BodyParseResult> parseBody`.
|
|
|
|
|
|
|
|
```dart
|
|
|
|
import 'dart:convert';
|
|
|
|
import 'package:body_parser/body_parser.dart';
|
|
|
|
|
|
|
|
main() async {
|
|
|
|
// ...
|
|
|
|
await for (HttpRequest request in server) {
|
|
|
|
request.response.write(JSON.encode(await parseBody(request).body));
|
|
|
|
await request.response.close();
|
|
|
|
}
|
|
|
|
}
|
|
|
|
```
|
|
|
|
|

|
|
|
You can also use `buildMapFromUri(Map, String)` to populate a map from a URL encoded string.
|
|
|
|
|
2016-03-04 04:30:13 +00:00
|
|
|
This can easily be used with a library like [JSON God](https://github.com/thosakwe/json_god)
|
|
|
|
to build structured JSON/REST APIs. Add validation and you've got an instant backend.
|
|
|
|
|
|
|
|
```dart
|
|
|
|
MyClass create(HttpRequest request) async {
|
|
|
|
return god.deserialize(await parseBody(request).body, MyClass);
|
|
|
|
}
|
|
|
|
```
