@Deprecated
public interface HttpMethod

Deprecated.

Jakarta Commons HttpClient 3.x is deprecated in the Jenkins project. It is not recommended to use it in any new code. Instead, use HTTP client API plugins as a dependency in your code. E.g. Apache HttpComponents Client API 4.x Plugin or Async HTTP Client Plugin.

HttpMethod interface represents a request to be sent via a HTTP connection and a corresponding response.

Since:

1.0

Method Detail

getName

java.lang.String getName()

Deprecated.

Obtains the name of the HTTP method as used in the HTTP request line, for example "GET" or "POST".

Returns:

the name of this method

getHostConfiguration

HostConfiguration getHostConfiguration()

Returns:

the HostConfiguration or null if none is set

setPath

void setPath(java.lang.String path)

Deprecated.

Sets the path of the HTTP method. It is responsibility of the caller to ensure that the path is properly encoded (URL safe).

Parameters:

path - The path of the HTTP method. The path is expected to be URL encoded.

getPath

java.lang.String getPath()

Deprecated.

Returns the path of the HTTP method. Calling this method after the request has been executed will return the actual path, following any redirects automatically handled by this HTTP method.

Returns:

the path of the HTTP method, in URL encoded form

getURI

URI getURI()
    throws URIException

Deprecated.

Returns the URI for this method. The URI will be absolute if the host configuration has been set and relative otherwise.

Returns:

the URI for this method

Throws:

URIException - if a URI cannot be constructed

Deprecated.

Use HttpParams.setParameter(String, Object) to exercise a more granular control over HTTP protocol strictness.

Defines how strictly the method follows the HTTP protocol specification. (See RFC 2616 and other relevant RFCs.) In the strict mode the method precisely implements the requirements of the specification, whereas in non-strict mode it attempts to mimic the exact behaviour of commonly used HTTP agents, which many HTTP servers expect.

Parameters:

strictMode - true for strict mode, false otherwise

See Also:

isStrictMode()

isStrictMode

boolean isStrictMode()

Deprecated.

Use HttpParams.setParameter(String, Object) to exercise a more granular control over HTTP protocol strictness.
