That is a default config preset, not an interceptor logic. I see no reason to change the current behavior that has developed historically. If the server does not support this header, there should be no problem. If the server processes the header, then the current value works for most users...
第一个Header是Content-Type,它指定了请求的数据格式为JSON。第二个Header是Authorization,它用于添加授权信息,例如API密钥或令牌。 类图 下面是一个使用mermaid语法的简单类图,展示了Axios中涉及到的类和它们之间的关系。 Axios+create(config: object) : AxiosInstanceAxiosInstance+request(config: object) : Promise+...
headers.test = 'I am only a header!'; return config; }, null, { synchronous: true }); If you want to execute a particular interceptor based on a runtime check, you can add a runWhen function to the options object. The request interceptor will not be executed if and only if the ...
function (config: AxiosRequestConfig) { // 全局请求的 loading,当请求 100 ms 后还没返回,才会出现 loading console.time('_axios.interceptors.request 请求设置header等等信息'); console.time('请求整理到返回中途所需要时间'); config.headers['request-startTime'] = new Date().getTime(); setBaseUrl(...
public class RemoteInterceptor implements HandlerInterceptor { @Override public boolean preHandle(HttpServletRequest request, HttpServletResponse resp, Object handler) throws Exception { // resp.addHeader("Access-Control-Allow-Origin","*"); resp.setHeader("Access-Control-Allow-Origin","*"); ...
而OPTIONS请求对于自定义的header有限制作用，往后端发送只会发送header的首部字段名，并不会发送该字段里具体内容信息，因此后端无法获取到uid和email的值，导致验证失败返回了401。先解决问题，由于访问量不大，可以通过修改服务端解决。继续针对OPTIONS请求加配置如下：@Componentpublic class CorsInterceptor extends ...
对于缓存的处理,使用拦截器(Interceptor)通常更为合适。理由如下: 职责分离: 请求拦截器(Request Interceptor)可以用于在发送请求前检查是否有可用的缓存,并决定是否从缓存中获取数据或继续发起网络请求。 响应拦截器(Response Interceptor)则可以在接收到服务器响应后,将数据存入缓存。
// Do something with request error if(config.showLoading) { tryHideFullScreenLoading(); } returnPromise.reject(error); } ); _axios.all = axios.all; _axios.spread = axios.spread; // Add a response interceptor _axios.interceptors.response.use( ...

to callaxios.interceptors.request.useto add a request interceptor. The first argument is a function that lets us change the request config before any request is made. In our example, we added thecontent-typerequest header to each request and set it to'text/json'. Therefore, all requests we...
