成员类型
enum QJsonParseError::ParseError
This enum describes the type of error that occurred during the parsing of a JSON document.
| Constant | Value | Description |
|---|---|---|
QJsonParseError::NoError | 0 | No error occurred |
QJsonParseError::UnterminatedObject | 1 | An object is not correctly terminated with a closing curly bracket |
QJsonParseError::MissingNameSeparator | 2 | A comma separating different items is missing |
QJsonParseError::UnterminatedArray | 3 | The array is not correctly terminated with a closing square bracket |
QJsonParseError::MissingValueSeparator | 4 | A colon separating keys from values inside objects is missing |
QJsonParseError::IllegalValue | 5 | The value is illegal |
QJsonParseError::TerminationByNumber | 6 | The input stream ended while parsing a number |
QJsonParseError::IllegalNumber | 7 | The number is not well formed |
QJsonParseError::IllegalEscapeSequence | 8 | An illegal escape sequence occurred in the input |
QJsonParseError::IllegalUTF8String | 9 | An illegal UTF8 sequence occurred in the input |
QJsonParseError::UnterminatedString | 10 | A string wasn't terminated with a quote |
QJsonParseError::MissingObject | 11 | An object was expected but couldn't be found |
QJsonParseError::DeepNesting | 12 | The JSON document is too deeply nested for the parser to parse it |
QJsonParseError::DocumentTooLarge | 13 | The JSON document is too large for the parser to parse it |
QJsonParseError::GarbageAtEnd | 14 | The parsed document contains additional garbage characters at the end |
成员函数
QString QJsonParseError::errorString() const
Returns the human-readable message appropriate to the reported JSON parsing error.
参见 error.
成员变量
ParseError QJsonParseError::error
Contains the type of the parse error. Is equal to QJsonParseError::NoError if the document was parsed correctly.
参见 ParseError and errorString().
int QJsonParseError::offset
Contains the offset in the input string where the parse error occurred.
参见 error and errorString().
