мой вопрос заключается в следующем У меня есть код:Как использовать API с яваскрипт и функции
const url = 'http://localhost:8080/users/[count]';
fetch(url)
.then((resp) => resp.json())
.then(function(data) {
for (i=o;i<data.length;i++) {
document.getElementById("Result").innerHTML = `<p>${data[i].name} ${data[i].username}</p>`
};
})
.catch(function(error) {
console.log(JSON.stringify(error));
});
, что в теории должно захватить информацию в адрес HTTP: // локальный: 8080/пользователи/[число ] и укажите мне имя и имя, указанные в этом адресе. Адрес имеет следующее:
