# `Python parser for RESTful HTTP requests`
A simple, lightweight parser for RESTful HTTP request data. `Python 3.6+`
_Installation_
```sh
pip install restparse
```
_Example usage:_
```py3
from restparse.parser import Parser
parser = Parser(description="RESTful parameter parser")
parser.add_param(
name="name",
type=str,
description="The users name",
required=True
)
parser.add_param(
name="age",
type=int,
description="The users age",
required=True
)
parser.add_param(
name="online",
type=bool,
description="Is the user online?",
default=False
)
parser.add_param(
name="height",
type=float,
description="The users height",
)
parser.add_param(
name="tags",
description="Tags",
)
payload = {
"name": "John Doe",
"age": "40",
"online": False,
"height": 6.2,
"tags": ["python", "javascript"]
}
params = parser.parse_params(payload)
print(params.name) # John Doe
print(params.tags) # ['python', 'javascript']
print(params.to_dict()) # {'name': 'John Doe', 'age': 40, 'online': False, 'height': 6.2, 'tags': ['python', 'javascript']}
```
### `Usage with Flask`
_Parsing query strings:_
```py3
@app.route("/")
def index():
""" Parsing query strings """
parser = Parser(description="Parsing query strings")
parser.add_param(
"q_from",
type=int,
description="Query from"
)
parser.add_param(
"q_to",
type=int,
description="Query to"
)
parser.add_param(
"search",
type=str,
description="Search query"
)
params = parser.parse_params(request.args)
print(params.q_from)
print(params.q_to)
print(params.search)
return f"Params = from: {params.q_from}, to: {params.q_to}, search: {params.search}"
```
_Parsing request payloads:_
```py3
@app.route("/json", methods=["POST"])
def json_payload():
""" Parsing request payloads """
parser = Parser(description="Parsing a request payload")
parser.add_param(
"name",
type=str,
description="The users name",
required=True
)
parser.add_param(
"age",
type=int,
description="The users age",
required=True
)
parser.add_param(
"tags",
type=list,
description="Tags"
)
params = parser.parse_params(request.get_json())
print(params.name)
print(params.age)
print(params.tags)
return jsonify(params.to_dict())
```
_Parsing form data:_
```py3
@app.route("/form", methods=["POST"])
def form_payload():
""" Parsing form data """
parser = Parser(description="Parsing form data")
parser.add_param(
"name",
type=str,
description="The users name",
required=True
)
parser.add_param(
"age",
type=int,
description="The users age",
required=True
)
params = parser.parse_params(request.form)
print(params.name)
print(params.age)
return redirect(url_for("index"))
```
### `add_param()`
```py3
parser.add_param(
"name",
type=str,
dest="new_name",
description="A description of the param",
required=True,
choices=["foo", "bar"]
)
```
_options:_
```
name (str): The parameter name
type (type): The type to which the parser should expect
dest (str): The name of the attribute to be added to the object returned by parse_params()
description (str): A description of the param
required (bool): Whether or not the param may be omitted
choices (container): A container of the allowable values for the argument
