方法详细资料

contentLength

public static long contentLength(Response response)

contentLength

public static long contentLength(Headers headers)

varyMatches

public static boolean varyMatches(Response cachedResponse,
 Headers cachedRequest,
 Request newRequest)

Returns true if none of the Vary headers have changed between cachedRequest and newRequest.

hasVaryAll

public static boolean hasVaryAll(Response response)

Returns true if a Vary header contains an asterisk. Such responses cannot be cached.

hasVaryAll

public static boolean hasVaryAll(Headers responseHeaders)

Returns true if a Vary header contains an asterisk. Such responses cannot be cached.

varyFields

public static Set<String> varyFields(Headers responseHeaders)

Returns the names of the request headers that need to be checked for equality when caching.

varyHeaders

public static Headers varyHeaders(Response response)

Returns the subset of the headers in response's request that impact the content of response's body.

varyHeaders

public static Headers varyHeaders(Headers requestHeaders,
 Headers responseHeaders)

Returns the subset of the headers in requestHeaders that impact the content of response's body.

parseChallenges

public static List<Challenge> parseChallenges(Headers responseHeaders,
 String headerName)

Parse RFC 7235 challenges. This is awkward because we need to look ahead to know how to interpret a token.

For example, the first line has a parameter name/value pair and the second line has a single token68:

   

   WWW-Authenticate: Digest foo=bar
   WWW-Authenticate: Digest foo=
 

Similarly, the first line has one challenge and the second line has two challenges:

   

   WWW-Authenticate: Digest ,foo=bar
   WWW-Authenticate: Digest ,foo
 

receiveHeaders

public static void receiveHeaders(CookieJar cookieJar,
 HttpUrl url,
 Headers headers)

hasBody

public static boolean hasBody(Response response)

Returns true if the response must have a (possibly 0-length) body. See RFC 7231.

skipUntil

public static int skipUntil(String input,
 int pos,
 String characters)

Returns the next index in input at or after pos that contains a character from characters. Returns the input length if none of the requested characters can be found.

skipWhitespace

public static int skipWhitespace(String input,
 int pos)

Returns the next non-whitespace character in input that is white space. Result is undefined if input contains newline characters.

parseSeconds

public static int parseSeconds(String value,
 int defaultValue)

Returns value as a positive integer, or 0 if it is negative, or defaultValue if it cannot be parsed.
