public final class SdkHttpUtils extends Object
A set of utilities that assist with HTTP message-related interactions.

  • Method Details

    • urlEncode

      public static String urlEncode(String value)
      Encode a string according to RFC 3986: encoding for URI paths, query strings, etc.

    • urlEncodeIgnoreSlashes

      public static String urlEncodeIgnoreSlashes(String value)
      Encode a string according to RFC 3986, but ignore "/" characters. This is useful for encoding the components of a path, without encoding the path separators.

    • formDataEncode

      public static String formDataEncode(String value)
      Encode a string according to RFC 1630: encoding for form data.

    • urlDecode

      public static String urlDecode(String value)
      Decode the string according to RFC 3986: encoding for URI paths, query strings, etc.

      Assumes the decoded string is UTF-8 encoded.

      Parameters:
      value - The string to decode.
      Returns:
      The decoded string.

    • encodeQueryParameters

      public static Map<String,List<String>> encodeQueryParameters(Map<String,List<String>> rawQueryParameters)
      Encode each of the keys and values in the provided query parameters using urlEncode(String).

    • encodeFormData

      public static Map<String,List<String>> encodeFormData(Map<String,List<String>> rawFormData)
      Encode each of the keys and values in the provided form data using formDataEncode(String).

    • encodeAndFlattenQueryParameters

      public static Optional<String> encodeAndFlattenQueryParameters(Map<String,List<String>> rawQueryParameters)
      Encode the provided query parameters using encodeQueryParameters(Map) and then flatten them into a string that can be used as the query string in a URL. The result is not prepended with "?".

    • encodeAndFlattenFormData

      public static Optional<String> encodeAndFlattenFormData(Map<String,List<String>> rawFormData)
      Encode the provided form data using encodeFormData(Map) and then flatten them into a string that can be used as the body of a form data request.

    • flattenQueryParameters

      public static Optional<String> flattenQueryParameters(Map<String,List<String>> toFlatten)
      Flatten the provided query parameters into a string that can be used as the query string in a URL. The result is not prepended with "?". This is useful when you have already-encoded query parameters you wish to flatten.

    • flattenQueryParameters

      public static void flattenQueryParameters(StringBuilder result, Map<String,List<String>> toFlatten)
      Flatten the provided query parameters into a string that can be used as the query string in a URL. The result is not prepended with "?". This is useful when you have already-encoded query parameters you wish to flatten.

    • isUsingStandardPort

      public static boolean isUsingStandardPort(String protocol, Integer port)
      Returns true if the specified port is the standard port for the given protocol. (i.e. 80 for HTTP or 443 for HTTPS). Null or -1 ports (to simplify interaction with URI's default value) are treated as standard ports.
      Returns:
      True if the specified port is standard for the specified protocol, otherwise false.

    • standardPort

      public static int standardPort(String protocol)
      Retrieve the standard port for the provided protocol.

    • appendUri

      public static String appendUri(String baseUri, String path)
      Append the given path to the given baseUri, separating them with a slash, if required. The result will preserve the trailing slash of the provided path.

    • allMatchingHeaders

      @Deprecated public static Stream<String> allMatchingHeaders(Map<String,List<String>> headers, String header)

      Perform a case-insensitive search for a particular header in the provided map of headers.
      Parameters:
      headers - The headers to search.
      header - The header to search for (case insensitively).
      Returns:
      A stream providing the values for the headers that matched the requested header.

    • allMatchingHeadersFromCollection

      @Deprecated public static Stream<String> allMatchingHeadersFromCollection(Map<String,List<String>> headersToSearch, Collection<String> headersToFind)
      Deprecated.

    • firstMatchingHeader

      @Deprecated public static Optional<String> firstMatchingHeader(Map<String,List<String>> headers, String header)
      Deprecated.
      Use SdkHttpHeaders#firstMatchingHeader
      Perform a case-insensitive search for a particular header in the provided map of headers, returning the first matching header, if one is found.
