nlohmann::basic_json::basic_json ( const CompatibleStringType &  val)
inline

Create a string JSON value with a given content.

Parameters
[in]vala value for the string
Template Parameters
CompatibleStringTypean string type which is compatible to string_t, for instance std::string.
Complexity
Linear in the size of the passed val.
Exceptions
std::bad_allocif allocation for string value fails
Example
The following code shows the construction of a string value from a compatible type.
1 #include <json.hpp>
2 
3 using json = nlohmann::json;
4 
5 int main()
6 {
7  // create a string value
8  std::string s = "The quick brown fox jumps over the lazy dog.";
9 
10  // create a JSON string value
11  json j = s;
12 
13  // serialize the JSON string
14  std::cout << j << '\n';
15 }
basic_json<> json
default JSON class
Definition: json.hpp:9587
Output (play with this example online):
"The quick brown fox jumps over the lazy dog."
The example code above can be translated with
