Detailed Description

Represents HTTP POST request with JSON body.

In addition to the requirements specified by the PostHttpRequest this class requires that the "Content-Type" is "application/json".

This class provides methods to parse and retrieve JSON data structures.

◆ PostHttpRequestJson() [2/2]

isc::http::PostHttpRequestJson::PostHttpRequestJson	(	const Method &	method,
		const std::string &	uri,
		const HttpVersion &	version,
		const HostHttpHeader &	host_header = HostHttpHeader(),
		const BasicHttpAuthPtr &	basic_auth = BasicHttpAuthPtr() )

explicit

Constructor for outbound HTTP request.

This constructor adds "Content-Type" header with the value of "application/json" to the context.

Parameters

method	HTTP method, e.g. POST.
uri	URI.
version	HTTP version.
host_header	Host header to be included in the request. The default is the empty Host header.
basic_auth	Basic HTTP authentication credential. The default is no authentication.

Member Function Documentation

◆ finalize()

void isc::http::PostHttpRequestJson::finalize ( )

virtual

Complete parsing of the HTTP request.

This method parses the JSON body into the structure of data::ConstElementPtr objects.

Reimplemented from isc::http::HttpRequest.

Definition at line 32 of file post_request_json.cc.

References isc::http::HttpRequest::create(), isc::http::HttpMessage::created_, isc::http::HttpMessage::finalized_, and parseBodyAsJson().

Here is the call graph for this function:

◆ getBodyAsJson()

ConstElementPtr isc::http::PostHttpRequestJson::getBodyAsJson ( ) const

Retrieves JSON body.

Returns: Pointer to the root element of the JSON structure.

Exceptions

HttpRequestJsonError if an error occurred.

Definition at line 49 of file post_request_json.cc.

References isc::http::HttpMessage::checkFinalized(), and json_.

Referenced by getJsonElement().

Here is the call graph for this function:

◆ getJsonElement()

ConstElementPtr isc::http::PostHttpRequestJson::getJsonElement ( const std::string & element_name ) const

Retrieves a single JSON element.

The element must be at top level of the JSON structure.

Parameters

element_name Element name.

Returns: Pointer to the specified element or NULL if such element doesn't exist.

Exceptions

HttpRequestJsonError if an error occurred.

Definition at line 66 of file post_request_json.cc.

References getBodyAsJson(), isc_throw, and isc::Exception::what().

Here is the call graph for this function:

◆ parseBodyAsJson()

void isc::http::PostHttpRequestJson::parseBodyAsJson ( )

protected

Interprets body as JSON, which can be later retrieved using data element objects.

Definition at line 85 of file post_request_json.cc.

References isc::http::HttpRequest::context_, isc::data::Element::create(), isc::data::Element::fromJSON(), isc_throw, json_, isc::data::Element::map, isc::http::HttpRequest::remote_, and isc::Exception::what().

Referenced by finalize().

Here is the call graph for this function:

◆ reset()

void isc::http::PostHttpRequestJson::reset ( )

virtual

Reset the state of the object.

Reimplemented from isc::http::HttpRequest.

Definition at line 43 of file post_request_json.cc.

References json_, and isc::http::HttpMessage::reset().

Here is the call graph for this function:

◆ setBodyAsJson()

void isc::http::PostHttpRequestJson::setBodyAsJson ( const data::ConstElementPtr & body )

Sets JSON body for an outbound message.

Note that this method copies the pointer to the body, rather than the entire data structure. Thus, the original object should not be modified after this method is called. If the specified pointer is null, the empty body is set.

Parameters

body	JSON structure to be used as a body.
