Method Description
CreateCookieContainer ( bool bAllowResponsesToModify ) : HTTPCookieContainerHandle

Creates a cookie container handle which you must later free with ReleaseCookieContainer(). If bAllowResponsesToModify=true

than any response to your requests using this cookie container may add new cookies which may be transmitted with

future requests. If bAllowResponsesToModify=false than only cookies you explicitly set will be sent. This API is just for

during process lifetime, after steam restarts no cookies are persisted and you have no way to access the cookie container across

repeat executions of your process.

CreateHTTPRequest ( EHTTPMethod eHTTPRequestMethod, string pchAbsoluteURL ) : HTTPRequestHandle

Initializes a new HTTP request, returning a handle to use in further operations on it. Requires

the method (GET or POST) and the absolute URL for the request. Both http and https are supported,

so this string must start with http:// or https:// and should look like http://store.steampowered.com/app/250/

or such.

DeferHTTPRequest ( HTTPRequestHandle hRequest ) : bool

Defers a request you have sent, the actual HTTP client code may have many requests queued, and this will move

the specified request to the tail of the queue. Returns false on invalid handle, or if the request is not yet sent.

GetHTTPDownloadProgressPct ( HTTPRequestHandle hRequest, float &pflPercentOut ) : bool

Gets progress on downloading the body for the request. This will be zero unless a response header has already been

received which included a content-length field. For responses that contain no content-length it will report

zero for the duration of the request as the size is unknown until the connection closes.

GetHTTPRequestWasTimedOut ( HTTPRequestHandle hRequest, bool &pbWasTimedOut ) : bool

Check if the reason the request failed was because we timed it out (rather than some harder failure)

GetHTTPResponseBodyData ( HTTPRequestHandle hRequest, byte pBodyDataBuffer, uint unBufferSize ) : bool

Gets the body data from a HTTP response given a handle from HTTPRequestCompleted_t, will return false if the

handle is invalid or is to a streaming response, or if the provided buffer is not the correct size. Use BGetHTTPResponseBodySize first to find out

the correct buffer size to use.

GetHTTPResponseBodySize ( HTTPRequestHandle hRequest, uint &unBodySize ) : bool

Gets the size of the body data from a HTTP response given a handle from HTTPRequestCompleted_t, will return false if the

handle is invalid.

GetHTTPResponseHeaderSize ( HTTPRequestHandle hRequest, string pchHeaderName, uint &unResponseHeaderSize ) : bool

Checks if a response header is present in a HTTP response given a handle from HTTPRequestCompleted_t, also

returns the size of the header value if present so the caller and allocate a correctly sized buffer for

GetHTTPResponseHeaderValue.

GetHTTPResponseHeaderValue ( HTTPRequestHandle hRequest, string pchHeaderName, byte pHeaderValueBuffer, uint unBufferSize ) : bool

Gets header values from a HTTP response given a handle from HTTPRequestCompleted_t, will return false if the

header is not present or if your buffer is too small to contain it's value. You should first call

BGetHTTPResponseHeaderSize to check for the presence of the header and to find out the size buffer needed.

GetHTTPStreamingResponseBodyData ( HTTPRequestHandle hRequest, uint cOffset, byte pBodyDataBuffer, uint unBufferSize ) : bool

Gets the body data from a streaming HTTP response given a handle from HTTPRequestDataReceived_t. Will return false if the

handle is invalid or is to a non-streaming response (meaning it wasn't sent with SendHTTPRequestAndStreamResponse), or if the buffer size and offset

do not match the size and offset sent in HTTPRequestDataReceived_t.

PrioritizeHTTPRequest ( HTTPRequestHandle hRequest ) : bool

Prioritizes a request you have sent, the actual HTTP client code may have many requests queued, and this will move

the specified request to the head of the queue. Returns false on invalid handle, or if the request is not yet sent.

ReleaseCookieContainer ( HTTPCookieContainerHandle hCookieContainer ) : bool

Release a cookie container you are finished using, freeing it's memory

ReleaseHTTPRequest ( HTTPRequestHandle hRequest ) : bool

Releases an HTTP response handle, should always be called to free resources after receiving a HTTPRequestCompleted_t

callback and finishing using the response.

SendHTTPRequest ( HTTPRequestHandle hRequest, SteamAPICall_t &pCallHandle ) : bool

Sends the HTTP request, will return false on a bad handle, otherwise use SteamCallHandle to wait on

asynchronous response via callback.

Note: If the user is in offline mode in Steam, then this will add a only-if-cached cache-control

header and only do a local cache lookup rather than sending any actual remote request.

SendHTTPRequestAndStreamResponse ( HTTPRequestHandle hRequest, SteamAPICall_t &pCallHandle ) : bool

Sends the HTTP request, will return false on a bad handle, otherwise use SteamCallHandle to wait on

asynchronous response via callback for completion, and listen for HTTPRequestHeadersReceived_t and

HTTPRequestDataReceived_t callbacks while streaming.

SetCookie ( HTTPCookieContainerHandle hCookieContainer, string pchHost, string pchUrl, string pchCookie ) : bool

Adds a cookie to the specified cookie container that will be used with future requests.

SetHTTPRequestAbsoluteTimeoutMS ( HTTPRequestHandle hRequest, uint unMilliseconds ) : bool

Set an absolute timeout on the HTTP request, this is just a total time timeout different than the network activity timeout

which can bump everytime we get more data

SetHTTPRequestContextValue ( HTTPRequestHandle hRequest, ulong ulContextValue ) : bool

Set a context value for the request, which will be returned in the HTTPRequestCompleted_t callback after

sending the request. This is just so the caller can easily keep track of which callbacks go with which request data.

SetHTTPRequestCookieContainer ( HTTPRequestHandle hRequest, HTTPCookieContainerHandle hCookieContainer ) : bool

Set the cookie container to use for a HTTP request

SetHTTPRequestGetOrPostParameter ( HTTPRequestHandle hRequest, string pchParamName, string pchParamValue ) : bool

Set a GET or POST parameter value on the request, which is set will depend on the EHTTPMethod specified

when creating the request. Must be called prior to sending the request. Will return false if the

handle is invalid or the request is already sent.

SetHTTPRequestHeaderValue ( HTTPRequestHandle hRequest, string pchHeaderName, string pchHeaderValue ) : bool

Set a request header value for the request, must be called prior to sending the request. Will

return false if the handle is invalid or the request is already sent.

SetHTTPRequestNetworkActivityTimeout ( HTTPRequestHandle hRequest, uint unTimeoutSeconds ) : bool

Set a timeout in seconds for the HTTP request, must be called prior to sending the request. Default

timeout is 60 seconds if you don't call this. Returns false if the handle is invalid, or the request

has already been sent.

SetHTTPRequestRawPostBody ( HTTPRequestHandle hRequest, string pchContentType, byte pubBody, uint unBodyLen ) : bool

Sets the body for an HTTP Post request. Will fail and return false on a GET request, and will fail if POST params

have already been set for the request. Setting this raw body makes it the only contents for the post, the pchContentType

parameter will set the content-type header for the request so the server may know how to interpret the body.

SetHTTPRequestRequiresVerifiedCertificate ( HTTPRequestHandle hRequest, bool bRequireVerifiedCertificate ) : bool

Set that https request should require verified SSL certificate via machines certificate trust store

SetHTTPRequestUserAgentInfo ( HTTPRequestHandle hRequest, string pchUserAgentInfo ) : bool

Set the extra user agent info for a request, this doesn't clobber the normal user agent, it just adds the extra info on the end
