javascript - 如何在 Promise 中仅返回解析类型？

Question

let companyInfo: PublicCompanyAPIResponseType;
companyInfo = await get<PublicCompanyAPIResponseType>({
    url: getCompanyDataURL,
}).catch(res => {
    responseStatus = res.status;
});

当我将 companyInfo 变量分配给该 get func

export async function get<T>({ url, headers }: ApiConnectSet): Promise<T> {
return new Promise((resolve, reject) => {
    fetch(url, {
        method: 'GET',
        credentials: 'same-origin',
        headers: headers,
    })
        .then(async res => {
            if (res.ok) {
                return resolve((await res.json()) as Promise<T>);
            } else if (res.status === 401) {
                const redirectPath = window.location.pathname;
                window.location.href =
                    '/login?redirectPath=' + redirectPath;
            } else {
                reject(res);
            }
        })
        .catch(error => {
            reject(error);
        });
});

}

Visual Studio 代码显示此错误


我的 get 函数如何只返回 PublicCompanyAPIResponseType ?

Answer 1

试试这个，如果它有效

let companyInfo: PublicCompanyAPIResponseType;
try {
  companyInfo = await get<PublicCompanyAPIResponseType>({
    url: getCompanyDataURL,
  })
} catch(err => {
    // get the status from error object and assign it to response status
    responseStatus = // your status code
});
