通过 react native 中的 fetch 从请求 api 获取状态和数据

Question

我尝试在使用此代码时从 React Native 的请求中提取数据和状态请求

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())
}

在此结果中没有状态。

当更改 return 函数时，我尝试获取状态，但在这种情况下无法访问数据

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

您可以执行以下操作

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

现在承诺的对象是

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

或者如果您不想要整个回复

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

最终的承诺是对象

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

Answer 2

那些 link 对我很有帮助。因为之前回答return

{ status: 200, json: Promise})
