axios-cookiejar-support与自定义https.Agent冲突报错求助

问题代码 #

const axios = require('axios')
const https = require('https');

const axiosCookieJarSupport = require("axios-cookiejar-support");
const tough = require("tough-cookie");

const HEADERS = {
    'Content-Type': 'application/json; odata.streaming=true; charset=utf-8',
    Accept: 'application/json; odata.metadata=none, text/plain',
    'TM1-SessionContext': '----',
    'User-Agent': '----'
  }
  
this.http = axios.create({
   headers: HEADERS,
   withCredentials: true,
   httpsAgent: new https.Agent({ rejectUnauthorized: false })
})
        
axiosCookieJarSupport.wrapper(this.http)
this.http.defaults.jar = new tough.CookieJar()
this.http.defaults.baseURL = this.baseUrl
    
// Then other things but that doesn't matter

报错信息 #

Error: axios-cookiejar-support does not support for use with other http(s).Agent.

解决方案 #

问题原因 #

axios-cookiejar-support需要接管axios实例的http/https Agent来实现Cookie管理，提前自定义Agent会触发冲突检测，导致报错。

修改后的代码 #

const axios = require('axios')
const axiosCookieJarSupport = require("axios-cookiejar-support");
const tough = require("tough-cookie");

const HEADERS = {
    'Content-Type': 'application/json; odata.streaming=true; charset=utf-8',
    Accept: 'application/json; odata.metadata=none, text/plain',
    'TM1-SessionContext': '----',
    'User-Agent': '----'
}

// 创建axios实例时不指定自定义httpsAgent
this.http = axios.create({
   headers: HEADERS,
   withCredentials: true
})

// 先包装实例以启用CookieJar支持
axiosCookieJarSupport.wrapper(this.http)
this.http.defaults.jar = new tough.CookieJar()
this.http.defaults.baseURL = this.baseUrl

// 通过axios-cookiejar-support提供的方法创建带自定义配置的httpsAgent
this.http.defaults.httpsAgent = new (axiosCookieJarSupport.getHttpsAgent(this.http))({
  rejectUnauthorized: false
})

说明 #

• 先创建基础axios实例，不设置httpsAgent
• 调用wrapper启用CookieJar支持后，再用axios-cookiejar-support.getHttpsAgent()创建符合要求的Agent，传入你的自定义配置（如rejectUnauthorized: false）
• 这种方式既保留了Cookie管理功能，又满足了自定义Agent的需求，无需使用axios其他特殊构造方法
