public HttpUtils()
推奨されていません。 
Constructs an empty HttpUtils object.

メソッドの詳細

parseQueryString

public static java.util.Hashtable parseQueryString(java.lang.String s)
推奨されていません。 
Parses a query string passed from the client to the server and builds a HashTable object with key-value pairs. The query string should be in the form of a string packaged by the GET or POST method, that is, it should have key-value pairs in the form key=value, with each pair separated from the next by a & character.

A key can appear more than once in the query string with different values. However, the key appears only once in the hashtable, with its value being an array of strings containing the multiple values sent by the query string.

The keys and values in the hashtable are stored in their decoded form, so any + characters are converted to spaces, and characters sent in hexadecimal notation (like %xx) are converted to ASCII characters.

パラメータ:
s - a string containing the query to be parsed
戻り値:
a HashTable object built from the parsed key-value pairs
例外:
java.lang.IllegalArgumentException - if the query string is invalid

parsePostData

public static java.util.Hashtable parsePostData(int len,
                                                ServletInputStream in)
推奨されていません。 
Parses data from an HTML form that the client sends to the server using the HTTP POST method and the application/x-www-form-urlencoded MIME type.

The data sent by the POST method contains key-value pairs. A key can appear more than once in the POST data with different values. However, the key appears only once in the hashtable, with its value being an array of strings containing the multiple values sent by the POST method.

The keys and values in the hashtable are stored in their decoded form, so any + characters are converted to spaces, and characters sent in hexadecimal notation (like %xx) are converted to ASCII characters.

パラメータ:
len - an integer specifying the length, in characters, of the ServletInputStream object that is also passed to this method
in - the ServletInputStream object that contains the data sent from the client
戻り値:
a HashTable object built from the parsed key-value pairs
例外:
java.lang.IllegalArgumentException - if the data sent by the POST method is invalid

getRequestURL

public static java.lang.StringBuffer getRequestURL(HttpServletRequest req)
推奨されていません。 
Reconstructs the URL the client used to make the request, using information in the HttpServletRequest object. The returned URL contains a protocol, server name, port number, and server path, but it does not include query string parameters.

Because this method returns a StringBuffer, not a string, you can modify the URL easily, for example, to append query parameters.

This method is useful for creating redirect messages and for reporting errors.

パラメータ:
req - a HttpServletRequest object containing the client's request
戻り値:
a StringBuffer object containing the reconstructed URL
