Decode the percent encoded input string into a UTF-8 string, according to the following rules.
- If the character is a '+', decode it as a space.
- If the character is a '', consume characters according to the decode algorithm given below.
- Otherwise, output the character as is.
The decode algorithm is as follows.
- Decode all successive sequences of XX, where each X is a hexadecimal ascii character in the ranges '0' to '9', 'a' to 'f', and 'A' to 'F', into bytes corresponding to the value obtained by converting the hexadecimal XX into an unsigned integer.
- Optionally, verify that the resulting byte sequence is valid UTF-8.
- Parameters
-
| input | the percent encoded input string |
| validateUtf8 | if true, the decoded percent encoded data will only be added if it is valid UTF-8 |
| throwOnError | if true, errors will cause an exception to be thrown instead of being silently ignored |
- Exceptions
-
| NetworkException | if throwOnError was set to true and the input was invalid |
◆ split()
| static std::unordered_map<std::string_view, std::string_view> split |
( |
const std::string_view |
data | ) |
|
|
inlinestatic |
Split the URL encoded parameters into a map of string views.
The caller is responsible for maintaining the original string onto which the views are pointing.
- Parameters
-
| data | the input string view containing the URL encoded parameters |
- Returns
- a hash map of split parameters, represented by string views onto the input string
- Exceptions
-
| NetworkException | if the parameter list was invalid |
◆ splitAndDecode()
| static std::unordered_map<std::string, std::string> splitAndDecode |
( |
const std::string_view & |
data, |
|
|
bool |
validateUtf8 = true, |

|
bool |
throwOnError = false |
|
) |
| |
|
inlinestatic |
Split the URL encoded parameters then decode each one.
- Parameters
-
| data | the input string containing the URL encoded parameters |
- Returns
- a hash map of split parameters, represented by strings
- Exceptions
-
| NetworkException | if the parameter list was invalid |
