Functions

func CheckPermissions

func CheckPermissions(writer http.ResponseWriter, request *http.Request, orgID types.OrgID, auth bool) bool

CheckPermissions checks whether user with a provided token(from request) can access current organization and handled the error on negative result by logging the error and writing a corresponding http response

func CreateOpenAPIHandler

func CreateOpenAPIHandler(filePath string, debug bool, cacheFile bool) func(writer http.ResponseWriter, request *http.Request)

CreateOpenAPIHandler creates a handler for a server to send OpenAPI file. Optionally, you can turn on or off debug to filter out debug endpoints. Optionally, you can turn on caching by setting cacheFile to true, then you will have to restart a server on each file change

func FilterOutDebugMethods

func FilterOutDebugMethods(openAPIFileContent string) (string, error)

FilterOutDebugMethods returns the same openapi spec, but without endpoints tagged as debug.

func GetRouterParam

func GetRouterParam(request *http.Request, paramName string) (string, error)

GetRouterParam retrieves parameter from URL like `/organization/{org_id}`

func GetRouterPositiveIntParam

func GetRouterPositiveIntParam(request *http.Request, paramName string) (uint64, error)

GetRouterPositiveIntParam retrieves parameter from URL like `/organization/{org_id}` and check it for being valid and positive integer, otherwise returns error

func HandleOrgIDError

func HandleOrgIDError(writer http.ResponseWriter, err error)

HandleOrgIDError logs org id error and writes corresponding http response

func LogRequest

func LogRequest(nextHandler http.Handler) http.Handler

LogRequest - middleware for logging requests

func MakeURLToEndpoint

func MakeURLToEndpoint(apiPrefix, endpoint string, args ...interface{}) string

MakeURLToEndpoint creates URL to endpoint, use constants from file endpoints.go

func MakeURLToEndpointMap

func MakeURLToEndpointMap(apiPrefix, endpoint string, args map[string]interface{}) string

MakeURLToEndpointMap creates URL to endpoint using arguments in map, use constants from file endpoints.go

func MakeURLToEndpointMapString

func MakeURLToEndpointMapString(apiPrefix, endpoint string, args map[string]string) string

MakeURLToEndpointMapString creates URL to endpoint using arguments in map in string format, use constants from file endpoints.go

func ReadClusterListFromBody

func ReadClusterListFromBody(writer http.ResponseWriter, request *http.Request) ([]string, bool)

ReadClusterListFromBody retrieves list of clusters from request's body if it's not possible, it writes http error to the writer and returns false

func ReadClusterListFromPath

func ReadClusterListFromPath(writer http.ResponseWriter, request *http.Request) ([]string, bool)

ReadClusterListFromPath retrieves list of clusters from request's path if it's not possible, it writes http error to the writer and returns false

func ReadClusterName

func ReadClusterName(writer http.ResponseWriter, request *http.Request) (types.ClusterName, bool)

ReadClusterName retrieves cluster name from request if it's not possible, it writes http error to the writer and returns false

func ReadClusterNames

func ReadClusterNames(writer http.ResponseWriter, request *http.Request) ([]types.ClusterName, bool)

ReadClusterNames does the same as `readClusterName`, except for multiple clusters.

func ReadErrorKey

func ReadErrorKey(writer http.ResponseWriter, request *http.Request) (types.ErrorKey, bool)

ReadErrorKey retrieves error key from request's url or writes an error to writer. The function returns an error key and a bool indicating if it was successful.

func ReadOrganizationID

func ReadOrganizationID(writer http.ResponseWriter, request *http.Request, auth bool) (types.OrgID, bool)

ReadOrganizationID retrieves organization id from request if it's not possible, it writes http error to the writer and returns false

func ReadOrganizationIDs

func ReadOrganizationIDs(writer http.ResponseWriter, request *http.Request) ([]types.OrgID, bool)

ReadOrganizationIDs does the same as `readOrganizationID`, except for multiple organizations.

func ReadRuleID

func ReadRuleID(writer http.ResponseWriter, request *http.Request) (types.RuleID, bool)

ReadRuleID retrieves rule id from request's url or writes an error to writer. The function returns a rule id and a bool indicating if it was successful.

func ReplaceParamsInEndpointAndTrimLeftSlash

func ReplaceParamsInEndpointAndTrimLeftSlash(endpoint, replacer string) string

ReplaceParamsInEndpointAndTrimLeftSlash replaces params in endpoint and trims left slash

func SplitRequestParamArray

func SplitRequestParamArray(arrayParam string) []string

SplitRequestParamArray takes a single HTTP request parameter and splits it into a slice of strings. This assumes that the parameter is a comma-separated array.

func ValidateClusterName

func ValidateClusterName(clusterName string) (types.ClusterName, error)

ValidateClusterName checks that the cluster name is a valid UUID. Converted cluster name is returned if everything is okay, otherwise an error is returned.
