DELETE(url: str, body: str|buf = "") -> Response|err: Convenience function for making a simple DELETE request.
GET(url: str) -> Response|err: Convenience function for making a simple GET request.

PUT(url: str, body: str|buf) -> Response|err: Convenience function for making a simple PUT request.

Requests

Request() -> Request: Creates a new Request object.

Request objects have the following public methods:

:append_args(*args: str) -> Request

Appends custom arguments for the curl binary.

Returns the request object to enable chaining.

:body(value: str|buf) -> Request

Sets the request's body to value.

Returns the request object to enable chaining.

:debug() -> Request

Turns on debug mode. Debug output is printed to the standard error stream.

Returns the request object to enable chaining.

:header(value: str) -> Request

Adds a header to the request.

Returns the request object to enable chaining.

:http_auth(username: str, password: str) -> Request

Adds authentication credentials in Basic HTTP Authentication format.

Returns the request object to enable chaining.

:url(value: str) -> Request

Sets the request's URL.

Returns the request object to enable chaining.

:param(key: any, value: any) -> Request

Adds a key/value parameter pair to the request — key and value will be automatically stringified if they are not already strings.

If the request is one of (GET, HEAD, OPTIONS), the parameter pair will be URL-encoded and appended to the URL's query string.

If the request is one of (POST, PUT, PATCH, DELETE), the parameter pair will be URL-encoded and appended to the request's body in application/x-www-form-urlencoded format. The appropriate Content-Type header will be automatically added to the request.

Returns the request object to enable chaining.

:timeout(seconds: f64) -> Request

Sets a timeout for the request, measured in (fractional) seconds. If the request hangs for longer than the specified timeout, it will return an err.

Returns the request object to enable chaining.

:DELETE() -> Response|err

Sends a DELETE request.

:GET() -> Response|err

Sends a GET request.

:HEAD() -> Response|err

Sends a HEAD request.

:OPTIONS() -> Response|err

Sends an OPTIONS request.

:PATCH() -> Response|err

Sends a PATCH request.

:POST() -> Response|err

Sends a POST request.

:PUT() -> Response|err

Sends a PUT request.

Responses

Response objects have the following public fields:

class Response {
    # The response's HTTP status code.
    pub var code: i64;

    # The response's body.
    pub var body: buf;

    # The response's headers, including the status line.
    pub var raw_headers: str;

    # The response's headers as a map of key/value pairs.
    # Keys are converted to lower-case ASCII.
    pub var headers: map[str, str];
}

Response objects have the following public methods:

:from_json() -> map|vec|str|i64|f64|bool|null|err

Attempts to parse the response body as JSON. Returns the resulting value.

Returns an err if the response body is not valid JSON.

:has_header(key: str) -> bool

Returns true if the response has a header named key, where key is a case-insensitive string.

:header(key: str) -> str|err

Returns the value of the header key, where key is a case-insensitive string.

Returns an err if the header does not exist.
