## Function Documentation

## ◆ sfHttp_create()

sfHttp * sfHttp_create | ( | void |  | ) |

Create a new Http object.

Returns
  A new sfHttp object

## ◆ sfHttp_destroy()

void sfHttp_destroy | ( | const sfHttp * | http | ) |

Destroy a Http object.

Parameters

  http | Http object to destroy

## ◆ sfHttp_sendRequest()

sfHttpResponse * sfHttp_sendRequest | ( | sfHttp * | http,
|  | const sfHttpRequest * | request,
|  | sfTime | timeout )

Send a HTTP request and return the server's response.

You must have a valid host before sending a request (see sfHttp_setHost). Any missing mandatory header field in the request will be added with an appropriate value. Warning: this function waits for the server's response and may not return instantly; use a thread if you don't want to block your application, or use a timeout to limit the time to wait. A value of 0 means that the client will use the system default timeout (which is usually pretty long).

Parameters

  http | Http object
  request | Request to send
  timeout | Maximum time to wait

Returns
  Server's response

## ◆ sfHttp_setHost()

void sfHttp_setHost | ( | sfHttp * | http,
|  | const char * | host,
|  | unsigned short | port )

Set the target host of a HTTP object.

This function just stores the host address and port, it doesn't actually connect to it until you send a request. If the port is 0, it means that the HTTP client will use the right port according to the protocol used (80 for HTTP, 443 for HTTPS). You should leave it like this unless you really need a port other than the standard one, or use an unknown protocol.

Parameters

  http | Http object
  host | Web server to connect to
  port | Port to use for connection

## ◆ sfHttpRequest_create()

sfHttpRequest * sfHttpRequest_create | ( | void |  | ) |

Create a new HTTP request.

Returns
  A new sfHttpRequest object

## ◆ sfHttpRequest_destroy()

void sfHttpRequest_destroy | ( | const sfHttpRequest * | httpRequest | ) |

Destroy a HTTP request.

Parameters

  httpRequest | HTTP request to destroy

## ◆ sfHttpRequest_setBody()

void sfHttpRequest_setBody | ( | sfHttpRequest * | httpRequest,
|  | const char * | body )

Set the body of a HTTP request.

The body of a request is optional and only makes sense for POST requests. It is ignored for all other methods. The body is empty by default.

Parameters

  httpRequest | HTTP request
  body | Content of the body

## ◆ sfHttpRequest_setField()

void sfHttpRequest_setField | ( | sfHttpRequest * | httpRequest,
|  | const char * | field,
|  | const char * | value )

Set the value of a header field of a HTTP request.

The field is created if it doesn't exist. The name of the field is case insensitive. By default, a request doesn't contain any field (but the mandatory fields are added later by the HTTP client when sending the request).

Parameters

  httpRequest | HTTP request
  field | Name of the field to set
  value | Value of the field

## ◆ sfHttpRequest_setHttpVersion()

void sfHttpRequest_setHttpVersion | ( | sfHttpRequest * | httpRequest,
|  | unsigned int | major,
|  | unsigned int | minor )

Set the HTTP version of a HTTP request.

The HTTP version is 1.0 by default.

Parameters

  httpRequest | HTTP request
  major | Major HTTP version number
  minor | Minor HTTP version number

## ◆ sfHttpRequest_setMethod()

void sfHttpRequest_setMethod | ( | sfHttpRequest * | httpRequest,
|  | sfHttpMethod | method )

Set a HTTP request method.

See the sfHttpMethod enumeration for a complete list of all the available methods. The method is sfHttpGet by default.

Parameters

  httpRequest | HTTP request
  method | Method to use for the request

## ◆ sfHttpRequest_setUri()

void sfHttpRequest_setUri | ( | sfHttpRequest * | httpRequest,
|  | const char * | uri )

Set a HTTP request URI.

The URI is the resource (usually a web page or a file) that you want to get or post. The URI is "/" (the root page) by default.

Parameters

  httpRequest | HTTP request
  uri | URI to request, relative to the host

## ◆ sfHttpResponse_destroy()

void sfHttpResponse_destroy | ( | const sfHttpResponse * | httpResponse | ) |

Destroy a HTTP response.

Parameters

  httpResponse | HTTP response to destroy

## ◆ sfHttpResponse_getBody()

const char * sfHttpResponse_getBody | ( | const sfHttpResponse * | httpResponse | ) |

Get the body of a HTTP response.

The body of a response may contain:

- the requested page (for GET requests)
- a response from the server (for POST requests)
- nothing (for HEAD requests)
- an error message (in case of an error)

Parameters

  httpResponse | HTTP response

Returns
  The response body

## ◆ sfHttpResponse_getField()

const char * sfHttpResponse_getField | ( | const sfHttpResponse * | httpResponse,
|  | const char * | field )

Get the value of a field of a HTTP response.

If the field field is not found in the response header, the empty string is returned. This function uses case-insensitive comparisons.

Parameters

  httpResponse | HTTP response
  field | Name of the field to get

Returns
  Value of the field, or empty string if not found

## ◆ sfHttpResponse_getMajorVersion()

unsigned int sfHttpResponse_getMajorVersion | ( | const sfHttpResponse * | httpResponse | ) |

Get the major HTTP version number of a HTTP response.

Parameters

  httpResponse | HTTP response

Returns
  Major HTTP version number

## ◆ sfHttpResponse_getMinorVersion()

unsigned int sfHttpResponse_getMinorVersion | ( | const sfHttpResponse * | httpResponse | ) |

Get the minor HTTP version number of a HTTP response.

Parameters

  httpResponse | HTTP response

Returns
  Minor HTTP version number

## ◆ sfHttpResponse_getStatus()

sfHttpStatus sfHttpResponse_getStatus | ( | const sfHttpResponse * | httpResponse | ) |

Get the status code of a HTTP response.

The status code should be the first thing to be checked after receiving a response, it defines whether it is a success, a failure or anything else (see the sfHttpStatus enumeration).

Parameters

  httpResponse | HTTP response

Returns
  Status code of the response
