HttpCurl Perl Reference Documentation
CkHttpCurl
Current Version: 11.4.0
A class for running curl commands within your application. Mirrors the curl command syntax. It is not derived from curl/libcurl, and does not wrap libcurl.
Object Creation
$obj = chilkat::CkHttpCurl->new();
Properties
DebugLogFilePath
# $ckStr is a CkString
$httpCurl->get_DebugLogFilePath($ckStr);
$strVal = $httpCurl->debugLogFilePath();
$httpCurl->put_DebugLogFilePath($strVal);
If set to a file path, this property logs the LastErrorText of each Chilkat method or property call to the specified file. This logging helps identify the context and history of Chilkat calls leading up to any crash or hang, aiding in debugging.
Enabling the VerboseLogging property provides more detailed information. This property is mainly used for debugging rare instances where a Chilkat method call causes a hang or crash, which should generally not happen.
Possible causes of hangs include:
- A timeout property set to 0, indicating an infinite timeout.
- A hang occurring within an event callback in the application code.
- An internal bug in the Chilkat code causing the hang.
EnableBodyVars
$boolVal = $httpCurl->get_EnableBodyVars();
$httpCurl->put_EnableBodyVars($boolVal);
Enables variable substitution in the body of the request. The default value is 1.
LastErrorHtml
# $ckStr is a CkString
$httpCurl->get_LastErrorHtml($ckStr);
$strVal = $httpCurl->lastErrorHtml();
Provides HTML-formatted information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.
topLastErrorText
# $ckStr is a CkString
$httpCurl->get_LastErrorText($ckStr);
$strVal = $httpCurl->lastErrorText();
Provides plain text information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.
LastErrorXml
# $ckStr is a CkString
$httpCurl->get_LastErrorXml($ckStr);
$strVal = $httpCurl->lastErrorXml();
Provides XML-formatted information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.
topLastMethodSuccess
$boolVal = $httpCurl->get_LastMethodSuccess();
$httpCurl->put_LastMethodSuccess($boolVal);
Indicates the success or failure of the most recent method call: 1 means success, 0 means failure. This property remains unchanged by property setters or getters. This method is present to address challenges in checking for null or Nothing returns in certain programming languages. Note: This property does not apply to methods that return integer values or to boolean-returning methods where the boolean does not indicate success or failure.
ResponseBodyStr
# $ckStr is a CkString
$httpCurl->get_ResponseBodyStr($ckStr);
$strVal = $httpCurl->responseBodyStr();
Returns the HTTP response body from the last call to DoYourThing .
ResponseFilePath
# $ckStr is a CkString
$httpCurl->get_ResponseFilePath($ckStr);
$strVal = $httpCurl->responseFilePath();
$httpCurl->put_ResponseFilePath($strVal);
Set this property to the path of a file to stream the response body to a file. If the response is streamed to a file, it will not be available in ResponseBodyStr , GetResponseSb , or GetResponseBd .
StatusCode
$intVal = $httpCurl->get_StatusCode();
Returns the HTTP status code from the last call to DoYourThing. A value of 0 indicates no response header was received.
Utf8
$boolVal = $httpCurl->get_Utf8();
$httpCurl->put_Utf8($boolVal);
When set to 1, all string arguments and return values are interpreted as UTF-8 strings. When set to 0, they are interpreted as ANSI strings.
In Chilkat v11.0.0 and later, the default value is 1. Before v11.0.0, it was 0.
VerboseLogging
$boolVal = $httpCurl->get_VerboseLogging();
$httpCurl->put_VerboseLogging($boolVal);
If set to 1, then the contents of LastErrorText (or LastErrorXml, or LastErrorHtml) may contain more verbose information. The default value is 0. Verbose logging should only be used for debugging. The potentially large quantity of logged information may adversely affect peformance.
Version
# $ckStr is a CkString
$httpCurl->get_Version($ckStr);
$strVal = $httpCurl->version();
Methods
AddFunction
# $curl is a string
$status = $httpCurl->AddFunction($funcName, $curl);
Adds a named curl function that can be used in dependency resolution. Inputs required by the curl function are indicated by the variable names enclosed in {{ and }}. Outputs are defined in one or more calls to AddOutput .
Returns 1 for success, 0 for failure.
topAddOutput
# $jsonPath is a string
# $varName is a string
$status = $httpCurl->AddOutput($funcName, $jsonPath, $varName);
Adds a defined output for a dependency resolution curl function previously defined by calling AddFunction. The jsonPath is the JSON path in the JSON response body where the varName's value is located.
Returns 1 for success, 0 for failure.
topAddTargetOutput
# $varName is a string
$status = $httpCurl->AddTargetOutput($jsonPath, $varName);
Adds an automatically mapped variable for the target curl command. When a JSON response is received from a curl request, the value at the JSON path specified by jsonPath is extracted (if present) and assigned to the variable named by varName.
This is useful in common workflows where one request returns an identifier (such as an `id`) that must be reused in a subsequent curl request.
Returns 1 for success, 0 for failure.
topClearTargetOutput
$httpCurl->ClearTargetOutput($varName);
Clears (undefines) the target output for the specified varName. If varName equals "*", then all target outputs are cleared.
ClearVar
$status = $httpCurl->ClearVar($varName);
Undefines the variable with the specified name. If varName equals "*", then all variables are cleared.
Returns 1 for success, 0 for failure.
topDoYourThing
$status = $httpCurl->DoYourThing($targetCurl);
Runs a the curl command specified in targetCurl. Returns success (1) if a response was received, in which case the response status code will be available in StatusCode and the content of the response body will be available in one of two places:
- If
ResponseFilePathis non-empty, the response body was streamed to the specified file path. - If
ResponseFilePathis empty, the response body can be retrieved viaResponseBodyStr,GetResponseSb, orGetResponseBd. Binary responses should only be retrieved viaResponseBodyBd.
Assuming the HTTP response is JSON, the target outputs (variables) specified by prior calls to AddTargetOutput will be populated by applying each variable's JSON path to the response JSON.
Returns 1 for success, 0 for failure.
topDoYourThingAsync (1)
Creates an asynchronous task to call the DoYourThing method with the arguments provided.
Returns null on failure
ExaminePlan
# $outStr is a CkString (output)
$status = $httpCurl->ExaminePlan($curl, $outStr);
$retStr = $httpCurl->examinePlan($curl);
Used for debugging. Returns a string that provides information about the plan of execution that would occur for the curl based on the variables that are either unknown or already known. The plan of execution is what would occur if DoYourThing was called with the current state of knowledge.
Returns 1 for success, 0 for failure.
topGetAllVars
Returns all defined variables in json.
topGetResponseBd
Writes to bd the HTTP response body from the last call to DoYourThing.
Returns 1 for success, 0 for failure.
topGetResponseJarr
Writes to jarr the HTTP response body from the last call to DoYourThing.
Returns 1 for success, 0 for failure.
topGetResponseJson
Writes to json the HTTP response body from the last call to DoYourThing.
Returns 1 for success, 0 for failure.
topGetResponseSb
Writes to sb the HTTP response body from the last call to DoYourThing.
Returns 1 for success, 0 for failure.
topGetResponseXml
Writes to xml the HTTP response body from the last call to DoYourThing.
Returns 1 for success, 0 for failure.
topGetVar
# $outStr is a CkString (output)
$status = $httpCurl->GetVar($varName, $outStr);
$retStr = $httpCurl->getVar($varName);
Retrieves the current value of the variable specified by varName.
Returns 1 for success, 0 for failure.
topSetAuth
Sets authorization information that is applied to all calls to DoYourThing . See the examples below for details.
Returns 1 for success, 0 for failure.
topSetVar
# $varValue is a string
$status = $httpCurl->SetVar($varName, $varValue);
Sets the value of a variable to be replaced in curl commands. Variable names are enclosed in {{ and }} and can occur in the path, query params, or the body of the request.
Returns 1 for success, 0 for failure.
ToRawRequest
# $sb is a CkStringBuilder
$status = $httpCurl->ToRawRequest($curlCommand, $sb);
Used for debugging purposes. This method behaves the same as DoYourThing , but only converts the curlCommand to an HTTP request message in sb containing the full structure:
- start line
- headers
- optional body or multipart body
It does not actually send the HTTP request.
Returns 1 for success, 0 for failure.
topVarDefined
$retBool = $httpCurl->VarDefined($varName);
Returns 1 if the varName is defined, otherwise returns 0. Setting varName to "!" checks whether all target output variables have been defined. It returns 1 if every target output is set, and 0 if any are missing.
