Question

以下是用于在令牌验证端点重试失败尝试的代码：

const axios = require('axios')
const rax = require('retry-axios')

try {
    const axiosInstance = axios.create();
    const myRaxConfig =  {
    instance: axiosInstance,
    retry: 4,
    statusCodesToRetry: [[100, 199], [401, 429, 429], [500, 501, 502, 504, 599]],
    httpMethodsToRetry: ['GET', 'HEAD', 'OPTIONS', 'DELETE', 'PUT', 'POST'],
    retryDelay: 100,
    noResponseRetries: 4,
    onRetryAttempt: (err) => {
        const cfg = rax.getConfig(err)
        console.log(`Retry attempt #${cfg.currentRetryAttempt}`);
    }
  }

  axiosInstance.defaults.raxConfig = myRaxConfig
  const interceptorId = rax.attach(axiosInstance);
  //const interceptorId = rax.attach()
  console.log("DOING THIS ONE +++++++++~~~~~~~~~~~~~~~~~~~~~~~")
  const tokenResult = await axiosInstance.post(`${process.env.URL}/api/token/verify`,
    {
      token
    },
  )
}
catch (err) {
   logger.error('encounter error in verify: ', err)
   //logger.error('encounter error in verify: ')

   return false
}

但是，错误日志显示正在使用默认配置-由于这是POST请求，因此未尝试重试：

错误输出：

 ...
 "headers":{"Accept":"application/json, text/plain, */*","Content-Type":"application/json;charset=utf-8","User-Agent":"axios/0.19.0","Content-Length":252},"transformRequest":[null],"transformResponse":[null],"timeout":0,"xsrfCookieName":"XSRF-TOKEN","xsrfHeaderName":"X-XSRF-TOKEN","maxContentLength":-1,
  "raxConfig":{"currentRetryAttempt":0,"retry":3,"retryDelay":100,"httpMethodsToRetry":["GET","HEAD","PUT","OPTIONS","DELETE"],"noResponseRetries":2,"statusCodesToRetry":[[100,199],[429,429],[500,599]]}}}

axios请求正在使用默认的retry-axios配置。

如何覆盖默认的raxConfig？

我疯狂地了解为什么我这样的简单代码无法正常工作。

嗯，我认为该库中存在一个错误。您在npm library usage中找到的以下代码无法正常工作：

const myAxiosInstance = axios.create();
myAxiosInstance.defaults.raxConfig = {
  instance: myAxiosInstance
};
const interceptorId = rax.attach(myAxiosInstance);
const res = await myAxiosInstance.get('https://test.local');

您必须将raxConfig对象添加到您的api调用中才能使工作正常。像这样：

const raxConfig = myAxiosInstance.defaults.raxConfig;
const res = await myAxiosInstance.get('https://test.local', { raxConfig } );

不要忘记在其中添加“实例”属性，否则它将无法正常工作。

覆盖retry-axios默认配置
