Interface for downloading HTTP, FTP documents.
void CPLHTTPDestroyResult | ( | CPLHTTPResult * | psResult | ) |
Clean the memory associated with the return value of CPLHTTPFetch()
psResult | pointer to the return value of CPLHTTPFetch() |
int CPLHTTPEnabled | ( | void | ) |
Return if CPLHTTP services can be useful.
Those services depend on GDAL being build with libcurl support.
CPLHTTPResult* CPLHTTPFetch | ( | const char * | pszURL, |
char ** | papszOptions | ||
) |
Fetch a document from an url and return in a string.
pszURL | valid URL recognized by underlying download library (libcurl) |
papszOptions | option list as a NULL-terminated array of strings. May be NULL. The following options are handled :
|
Alternatively, if not defined in the papszOptions arguments, the PROXY, PROXYUSERPWD, PROXYAUTH and NETRC values are searched in the configuration options named GDAL_HTTP_PROXY, GDAL_HTTP_PROXYUSERPWD, GDAL_PROXY_AUTH and GDAL_HTTP_NETRC, as proxy configuration belongs to networking setup and makes more sense at the configuration option level than at the connection level.
int CPLHTTPParseMultipartMime | ( | CPLHTTPResult * | psResult | ) |
Parses a a MIME multipart message.
This function will iterate over each part and put it in a separate element of the pasMimePart array of the provided psResult structure.
psResult | pointer to the return value of CPLHTTPFetch() |
char* GOA2GetAuthorizationURL | ( | const char * | pszScope | ) |
Return authorization url for a given scope.
Returns the URL that a user should visit, and use for authentication in order to get an "auth token" indicating their willingness to use a service.
Note that when the user visits this url they will be asked to login (using a google/gmail/etc) account, and to authorize use of the requested scope for the application "GDAL/OGR". Once they have done so, they will be presented with a lengthy string they should "enter into their application". This is the "auth token" to be passed to GOA2GetRefreshToken(). The "auth token" can only be used once.
This function should never fail.
pszScope | the service being requested, not yet URL encoded, such as "https://www.googleapis.com/auth/fusiontables". |
char* GOA2GetRefreshToken | ( | const char * | pszAuthToken, |
const char * | pszScope | ||
) |
Turn Auth Token into a Refresh Token.
A one time "auth token" provided by the user is turned into a reusable "refresh token" using a google oauth2 web service.
A CPLError will be reported if the translation fails for some reason. Common reasons include the auth token already having been used before, it not being appropriate for the passed scope and configured client api or http connection problems. NULL is returned on error.
pszAuthToken | the authorization token from the user. |
pszScope | the scope for which it is valid. |
