Table 2 Request header parameters
Parameter	Mandatory	Type	Description
X-Auth-Token	Yes	String	Specifies the token used for IAM authentication.

Table 3 Request body parameters
Parameter	Mandatory	Type	Description
rule	Yes	UpdateL7RuleOption object	Specifies the forwarding rule.

Table 4 UpdateL7RuleOption
Parameter	Mandatory	Type	Description
admin_state_up	No	Boolean	Specifies the administrative status of the forwarding rule. The value can only be true.
compare_type	No	String	Specifies how requests are matched with the forwarding rule. Value options: EQUAL_TO: exact match. REGEX: regular expression match STARTS_WITH: prefix match Note: If type is set to HOST_NAME, the value can only be EQUAL_TO, and asterisks () can be used as wildcard characters. If type is set to PATH, the value can be REGEX, STARTS_WITH, or EQUAL_TO. If type is set to METHOD or SOURCE_IP, the value can only be EQUAL_TO. If type is set to HEADER or QUERY_STRING, the value can only be EQUAL_TO, asterisks () and question marks (?) can be used as wildcard characters.
invert	No	Boolean	Specifies whether reverse matching is supported. The value can be true or false. This parameter is unsupported. Please do not use it.
key	No	String	Specifies the key of the match item. For example, if an HTTP header is used for matching, key is the name of the HTTP header parameter. This parameter is unsupported. Please do not use it.
value	No	String	Specifies the value of the match item. For example, if a domain name is used for matching, value is the domain name. Note: This parameter will take effect only when conditions is left blank. If type is set to HOST_NAME, the value can contain letters, digits, hyphens (-), and periods (.) and must start with a letter or digit. If you want to use a wildcard domain name, enter an asterisk () as the leftmost label of the domain name. If type is set to PATH and compare_type to STARTS_WITH or EQUAL_TO, the value must start with a slash (/) and can contain only letters, digits, and special characters _~';@^-%#&$.+?,=!:\|\/()[]{} If type is set to METHOD, SOURCE_IP, HEADER, or QUERY_STRING, this parameter will not take effect, and conditions will be used to specify the key and value.
conditions	No	Array of UpdateRuleCondition objects	Specifies the conditions contained in a forwarding rule. Note: This parameter will take effect when enhance_l7policy_enable is set to true. If conditions is specified, key and value will not take effect. The keys in the list must be the same, whereas each value must be unique.

Table 5 UpdateRuleCondition
Parameter	Mandatory	Type	Description
key	No	String	Specifies the key of match item. Note: All keys in the conditions list in the same rule must be the same. If type is set to HOST_NAME, PATH, METHOD, or SOURCE_IP, this parameter is an empty string. If type is set to HEADER, key indicates the name of the HTTP header parameter, and value indicates the value of the request header parameter. The value can contain 1 to 40 characters, including letters, digits, hyphens (-), and underscores (_). If type is set to QUERY_STRING, key indicates the name of the query parameter, and value indicates the value of the query parameter. The key is case sensitive and can contain 1 to 128 characters. Spaces, square brackets ([ ]), curly brackets ({ }), angle brackets (< >), backslashes (), double quotation marks (" "), pound signs (#), ampersands (&), vertical bars (\|), percent signs (%), and tildes (~) are not supported.
value	No	String	Specifies the value of the match item. Note: The key of each condition in a forwarding policy must be the same. The value of each condition in a forwarding policy must be unique. Value ranges: If type is set to HOST_NAME, key is left blank, value indicates the domain name, which can contain 1 to 128 characters, including letters, digits, hyphens (-), periods (.), and asterisks (), and must start with a letter, digit, or asterisk (). If you want to use a wildcard domain name, enter an asterisk () as the leftmost label of the domain name. If type is set to PATH, key is left blank, value indicates the request path, which can contain 1 to 128 characters. If compare_type is set to STARTS_WITH or EQUAL_TO for the forwarding rule, the value must start with a slash (/) and can contain only letters, digits, and special characters: _~';@^-%#&$.+?,=!:\|/()[]{} If type is set to HEADER, key indicates the name of the HTTP header parameter and value indicates the value of the HTTP header parameter. The value can contain 1 to 128 characters. Asterisks () and question marks (?) are allowed, but spaces and double quotation marks are not allowed. An asterisk can match zero or more characters, and a question mark can match 1 character. If type is set to QUERY_STRING, key indicates the name of the query parameter and value indicates the value of the query parameter. The value is case sensitive and can contain 1 to 128 characters. Spaces, square brackets ([ ]), curly brackets ({ }), angle brackets (< >), backslashes (), double quotation marks (" "), pound signs (#), ampersands (&), vertical bars (\|), percent signs (%), and tildes (~) are not supported. Asterisks () and question marks (?) are allowed. An asterisk can match zero or more characters, and a question mark can match 1 character. If type is set to METHOD, key is left blank, value indicates the HTTP method. The value can be GET, PUT, POST, DELETE, PATCH, HEAD, or OPTIONS. If type is set to SOURCE_IP, key is left blank, value indicates the source IP address of the request. The value is an IPv4 or IPv6 CIDR block, for example, 192.168.0.2/32 or 2049::49/64.
