回答: 要将QString转换为QVariantMap,可以使用QJsonDocument和QJsonObject来实现。首先,将QString转换为QJsonDocument,然后使用toVariantMap()函数将QJsonObject转换为QVariantMap。以下是一个示例代码:
```cpp
QString jsonString = "{\"key1\": \"value1\", \"key2\": \"value2\", \"key3\": \"value3\"}";
QJsonDocument jsonDocument = QJsonDocument::fromJson(jsonString.toUtf8());
QJsonObject jsonObject = jsonDocument.object();
QVariantMap variantMap = jsonObject.toVariantMap();
```
在这个示例中,我们首先将QString转换为QJsonDocument,然后将QJsonDocument转换为QJsonObject,最后将QJsonObject转换为QVariantMap。这样就可以将QString转换为QVariantMap了。
