提取:“字符串"类型的参数|未定义"不能分配给"RequestInfo"类型的参数 [英] Fetch : Argument of type 'string | undefined' is not assignable to parameter of type 'RequestInfo'

问题描述

我在"fetchUrl"中收到以下错误:fetch函数中的参数

'string |类型的参数未定义"不能分配给参数类型为"RequestInfo".

此功能

  let fetchUrl = getBaseUrlNative(process.env.APP_DATA，`/v2/marketing/app/file/$ {file}?cookies = $ {cookieSess}& expires = $ {Date.now()}`)等待fetch(fetchUrl，{方法:获取"，缓存:无存储"，标头:{'Cache-Control':'no-cache'}}).then(res => res.blob()).then(res => {....... 

getBaseUrlNative是

  export const getBaseUrlNative =(eUrl:字符串|未定义，ext:字符串|未定义)=>{尝试 {如果(！eUrl)抛出新的错误(``Error.'')返回分机?eUrl + ext:eUrl;} catch(err){console.log(err)}} 

解决方案

在fetch函数中使用 any 数据类型禁止类型检查.

 让fetchUrl = getBaseUrlNative(process.env.APP_DATA，`/v2/marketing/app/file/$ {file}?cookies = ${cookieSess}& expires = $ {Date.now()}`)等待fetch(< any> fetchUrl，{方法:获取"，缓存:无存储"，标头:{'Cache-Control':'no-cache'}}).then(res => res.blob()).then(res => {.......  

Im receiving the following error in the "fetchUrl" argument in the fetch function

Argument of type 'string | undefined' is not assignable to parameter of type 'RequestInfo'.

In this function

let fetchUrl = getBaseUrlNative( process.env.APP_DATA, `/v2/marketing/app/file/${file}?cookies=${cookieSess}&expires=${Date.now()}`)

    await fetch(fetchUrl, { method: 'get' , cache:"no-store" , headers: {
        'Cache-Control': 'no-cache'
      }})
         .then(res => res.blob())
         .then(res => {  .......

getBaseUrlNative is

export const getBaseUrlNative = (eUrl : string | undefined, ext : string | undefined) => {
    try {
        if (!eUrl) throw new Error("Error .")
        return ext ? eUrl+ext : eUrl;
    } catch (err) {
        console.log(err)
    }
}

解决方案

Use the any data type in the fetch function to disallow type checking.

let fetchUrl = getBaseUrlNative( process.env.APP_DATA, `/v2/marketing/app/file/${file}?cookies=${cookieSess}&expires=${Date.now()}`)

    await fetch(<any>fetchUrl, { method: 'get' , cache:"no-store" , headers: {
        'Cache-Control': 'no-cache'
      }})
         .then(res => res.blob())
         .then(res => {  .......
