示例1: executeField

function executeField(
  field: FieldNode,
  rootValue: any,
  execContext: ExecContext,
): any {
  const { variableValues: variables, contextValue, resolver } = execContext;

  const fieldName = field.name.value;
  const args = argumentsObjectFromField(field, variables);

  const info: ExecInfo = {
    isLeaf: !field.selectionSet,
    resultKey: resultKeyNameFromField(field),
    directives: getDirectiveInfoFromField(field, variables),
    field,
  };

  const result = resolver(fieldName, rootValue, args, contextValue, info);

  // Handle all scalar types here
  if (!field.selectionSet) {
    return result;
  }

  // From here down, the field has a selection set, which means it's trying to
  // query a GraphQLObjectType
  if (result == null) {
    // Basically any field in a GraphQL response can be null, or missing
    return result;
  }

  if (Array.isArray(result)) {
    return executeSubSelectedArray(field, result, execContext);
  }

  // Returned value is an object, and the query has a sub-selection. Recurse.
  return executeSelectionSet(field.selectionSet, result, execContext);
}
