Detailed Description

HTTP client request.

This contains all the data that is needed when doing a HTTP request.

Field Documentation

◆ content_type_value

const char* http_request::content_type_value

The value of the Content-Type header field, may be NULL.

◆ data_len

size_t http_request::data_len

Length of the unprocessed data left inside the user supplied receive buffer.

In typical HTTP processing this should be 0, however in case of switching protocols, there may be some data left belonging to the new protocol.

◆ header_fields

const char* const* http_request::header_fields

The HTTP header fields (application specific) The Content-Type may be specified here or in the next field.

Depending on your application, the Content-Type may vary, however some header fields may remain constant through the application's life cycle. This is a NULL terminated list of header fields.

◆ host

const char* http_request::host

Hostname to be used in the request.

◆ http_cb

const struct http_parser_settings* http_request::http_cb

User supplied list of HTTP callback functions if the calling application wants to know the parsing status or the HTTP fields.

This is optional and normally not needed.

◆ internal

struct http_client_internal_data http_request::internal

HTTP client request internal data.

◆ method

enum http_method http_request::method

The HTTP method: GET, HEAD, OPTIONS, POST, ...

◆ optional_headers

const char** http_request::optional_headers

A NULL terminated list of any optional headers that should be added to the HTTP request.

May be NULL. If the optional_headers_cb is specified, then this field is ignored. Note that there are two similar fields that contain headers, the header_fields above and this optional_headers. This is done like this to support Websocket use case where Websocket will use header_fields variable and any optional application specific headers will be placed into this field.

◆ optional_headers_cb

http_header_cb_t http_request::optional_headers_cb

User supplied callback function to call when optional headers need to be sent.

This can be NULL, in which case the optional_headers field in http_request is used. The idea of this optional_headers callback is to allow user to send more HTTP header data that is practical to store in allocated memory.

◆ payload

const char* http_request::payload

Payload, may be NULL.

◆ payload_cb

http_payload_cb_t http_request::payload_cb

User supplied callback function to call when payload needs to be sent.

This can be NULL in which case the payload field in http_request is used. The idea of this payload callback is to allow user to send more data that is practical to store in allocated memory.

◆ payload_len

size_t http_request::payload_len

Payload length is used to calculate Content-Length.

Set to 0 for chunked transfers.

◆ port

const char* http_request::port

Port number to be used in the request.

◆ protocol

const char* http_request::protocol

The HTTP protocol, for example "HTTP/1.1".

◆ recv_buf

uint8_t* http_request::recv_buf

User supplied buffer where received data is stored.

◆ recv_buf_len

size_t http_request::recv_buf_len

Length of the user supplied receive buffer.

◆ response

http_response_cb_t http_request::response

User supplied callback function to call when response is received.

◆ url

const char* http_request::url

The URL for this request, for example: /index.html.
