[英]How to get the content-length of the response from a request with fetch()
[英]How to get the Content-Length header from a POST request send with axios?
我想使用我的 POST 請求的大小和數據。 我正在做一些研究,發現了一個請求的 Content-Length header,但我在我的 axios 請求標頭中找不到它。
我嘗試使用攔截器,如下所示:
axios.interceptors.request.use(
config => {
console.log('config', config.headers);
if (config.url != `${API_URL}/login`)
config.headers.Authorization = 'Bearer ' + getAccessToken();
return config;
},
error => {
return Promise.reject(error);
}
);
這是我得到的回應:
Authorization: "Bearer [...access_token]"
Content-Type: "multipart/form-data"
common:
Accept: "application/json, text/plain, */*"
X-CSRF-TOKEN: "..."
X-Requested-With: "XMLHttpRequest"
__proto__: Object
delete: {}
get: {}
head: {}
patch: {Content-Type: "application/x-www-form-urlencoded"}
post: {Content-Type: "application/x-www-form-urlencoded"}
put: {Content-Type: "application/x-www-form-urlencoded"}
但在 Chrome 中顯示的是:
Accept: application/json, text/plain
Accept-Encoding: gzip, deflate
Accept-Language: en-US,en;q=0.9,ro;q=0.8,la;q=0.7
Authorization: Bearer [...access_token]
Connection: keep-alive
Content-Length: 5266672 <---- this is what I need
Content-Type: multipart/form-data; boundary=----WebKitFormBoundaryGMzak87LIZH05nme
Cookie: XSRF-TOKEN= ...
Host: ...
Origin: ...
Referer: ...
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/77.0.3865.90 Safari/537.36
X-CSRF-TOKEN: ...
X-Requested-With: XMLHttpRequest
X-XSRF-TOKEN: ...
有沒有辦法讓 axios 給我內容長度 header? 如果沒有,有沒有辦法從其他任何地方訪問它?
content-length 將由http 適配器自動添加。
