Description
Format ordered HTTP parameter records with token-or-quoted-string values, preserving repeated names and order; no RFC 8187 extended-value inference.
HTTP field names are case-insensitive, while values follow each field’s own grammar. Repeated occurrences sometimes form lists but cannot always be combined. Quoted values, optional spaces/tabs and quality weights need their own treatment; the tools here use explicit field records or a stated text subset.1
Format ordered HTTP parameter records with token-or-quoted-string values, preserving repeated names and order; no RFC 8187 extended-value inference.
When to use this tool
Use this tool to format ordered HTTP parameter records with token-or-quoted-string values, preserving repeated names and order; no RFC 8187 extended-value inference.
How to use the tool and how it works
- Enter parametersJson using the field definitions below. For JSON text, serialize the explicit records in the shown shape.
- Run the operation. Correct input errors before interpreting an output.
- Read result.parameters. Use the ordering, boundary rules and absence conditions described below.
Normalize parameter names and serialize supplied records in order, quoting and escaping values when required and preserving duplicate names.2
| Input field | Meaning and units | Accepted input |
|---|---|---|
| parametersJson | JSON text encoding array of {name: string, value: string}. Keep the record keys and value types shown in the decoded example below. | Text, at most 8,192 UTF-16 code units; the operation’s grammar also applies. |
These are the decoded structures used in the example’s JSON text fields. Supply the corresponding serialized JSON strings as input.
{
"parametersJson": [
{
"name": "A",
"value": "x y"
},
{
"name": "a",
"value": "z"
}
]
}| Output field | Interpretation |
|---|---|
| result | Object containing the named fields below. |
| result.parameters | Normalized ordered parameter text without a leading media type. |
{
"input": {
"parametersJson": "[{\"name\":\"A\",\"value\":\"x y\"},{\"name\":\"a\",\"value\":\"z\"}]"
},
"output": {
"result": {
"parameters": "a=\"x y\"; a=z"
}
}
}Limitations and assumptions
- This returns the parameter portion without a leading media type or complete header line.
- Explicit header records have name and value strings. Names must use token syntax; supported value code units are tab or 32–255 excluding DEL. Byte budgets use that single-byte representation, not UTF-8 or HTTP/2 compression.
- Every declared top-level input field is required and unexpected fields are rejected. Ordinary strings are limited to 8,192 UTF-16 code units and lists to 128 entries, with tighter operation-specific bounds where stated. JSON text has bounded nesting and node counts.
- Numeric outputs must be finite and no larger in absolute magnitude than the safe-integer limit; operations returning exact large integers use decimal text. Positions are zero-based and spans end exclusively unless the operation explicitly states a different convention.
Alternative or Complementary methods
Choose field-specific parsing and combination rules rather than applying one policy to every header. Preserve occurrence order and use a full HTTP implementation for message framing and protocol-level decisions.
