查询GraphQL Mutation Schema

Question

有没有办法使用HTTP查询graphql服务器的突变模式？或者查询graphql server的整个架构的方法？谢谢！

Answer 1

当然可以。官方GraphQL规范概述了the introspection specifics。获取可用突变的示例可能如此......

#include <iostream>
using namespace std;

int main()
{

int num1; //I get an error message when I do not set it to 0.
int num2;
int num3; 

cout << "Please enter three numbers: " << endl;
cin >> num1; num2; num3; 

if (num1 > num2 && num2 > num3){
    cout << "In ascending order: " << num1 << num2 << num3 << endl;
}
else if (num2 > num1 && num1 > num3)
{
    cout << "In ascending order: " << num2 << num1 << num3 << endl;
}
else if (num3 > num1 && num1 > num2){
    cout << "In ascending order: " << num3 << num1 << num2 << endl;
}
else
{
    cout << "There was an invalid input." << endl; 
}

system("pause");
return 0;
}
