BAS Можно ли выполнить javascript код в http клиенте?

Можно, вот пример

// Выполнение GET-запроса
fetch('https://api.example.com/data')
.then(response => {
if (!response.ok) {
throw new Error('Network response was not ok ' + response.statusText);
}
return response.json();
})
.then(data => console.log(data))
.catch(error => console.error('There has been a problem with your fetch operation:', error));

// Выполнение POST-запроса
fetch('https://api.example.com/data', {
method: 'POST',
headers: {
'Content-Type': 'application/json'
},
body: JSON.stringify({ key: 'value' })
})
.then(response => {
if (!response.ok) {
throw new Error('Network response was not ok ' + response.statusText);
}
return response.json();
})
.then(data => console.log(data))
.catch(error => console.error('There has been a problem with your fetch operation:', error));

HTML

// Выполнение GET-запроса

fetch('https://api.example.com/data')

  .then(response => {

    if (!response.ok) {

      throw new Error('Network response was not ok ' + response.statusText);

    }

    return response.json();

  })

  .then(data => console.log(data))

  .catch(error => console.error('There has been a problem with your fetch operation:', error));



// Выполнение POST-запроса

fetch('https://api.example.com/data', {

  method: 'POST',

  headers: {

    'Content-Type': 'application/json'

  },

  body: JSON.stringify({ key: 'value' })

})

  .then(response => {

    if (!response.ok) {

      throw new Error('Network response was not ok ' + response.statusText);

    }

    return response.json();

  })

  .then(data => console.log(data))

  .catch(error => console.error('There has been a problem with your fetch operation:', error));

UPD1: идет через FETCH API

 

как вообще связан JS код и HTTP клиент баса. Ты чет не туда капаешь
