通过在React Native中获取来从请求api获取状态和数据

Question

I try extract data and status request from request in react native, when utilize this code

function postUser(FirstName, LastName, Phone, Email, Password) {
    let data = {
        method: 'POST',
        credentials: 'same-origin',
        mode: 'same-origin',
        headers: {
            'Accept': 'application/json',
            'Content-Type': 'application/json'
        },
        body: JSON.stringify({
            email: Email,
            password: Password,
            first_name: FirstName,
            last_name: LastName,
            phone: Phone
        })
    }
    return fetch(URLPostUser, data)
        .then(response => response.json())
} 

in this result don't had status.

when change the return of function, i try get status, but in this case don't have access to data

function postUser(FirstName, LastName, Phone, Email, Password) {
    let data = {
        method: 'POST',
        credentials: 'same-origin',
        mode: 'same-origin',
        headers: {
            'Accept': 'application/json',
            'Content-Type': 'application/json'
        },
        body: JSON.stringify({
            email: Email,
            password: Password,
            first_name: FirstName,
            last_name: LastName,
            phone: Phone
        })
    }
    return fetch(URLPostUser, data)
}

Answer 1

You can do the following

return fetch(URLPostUser, data)
    .then(response => ({ response, json: response.json()}))

Now the promised object is

{
    response: // the response object
    json: // the parsed JSON
}

Or if you don't want the whole response

return fetch(URLPostUser, data)
    .then(response => ({ status: response.status, json: response.json()}))

The resulting promise is of the object

{
    status: // the response object
    json: // the parsed JSON
}

Those link was helpful for me. Because previously answer return

{ status: 200, json: Promise})
