如何将Cypress中request请求的body保存为变量供其他请求复用

方法1：同上下文直接定义变量（最简单） #

直接把需要复用的Body内容抽出来定义为普通JS变量，同一测试文件/同一测试上下文内所有请求都可以直接调用，且Random生成的字段值只会生成一次，保证所有请求使用的参数一致。
代码示例：

// 提前定义复用的Body
const affiliateCreateBody = {
  "address": Random.address,
  "address_complement": Random.address_complement,
  "address_city": Random.address_city,
  "address_number": `${Random.address_number}`,
  "address_district": Random.address_district,
  "address_state": Random.address_state,
  "cep": `${Random.cep}`,
  "cnpj": Random.cnpj,
  "company_name": Random.company_name,
  "headquarters": fAffiliate.headquarters[1],
  "ie": `${Random.ie}`,
  "phone": Random.phone,
  "rntrc": `${Random.rntrc}`,
  "status": fAffiliate.status[0],
  "trading_name": Random.trading_name
}

// 原请求简化为
cy.request({
    url: "/api/affiliate/create",
    method: "POST",
    headers:
    {
        Authorization: `bearer ${access_token}`,
    },
    body: affiliateCreateBody
})

其他请求需要使用时直接传入affiliateCreateBody变量即可。

方法2：跨测试文件复用 #

如果需要在多个测试文件里复用该Body，可以把逻辑封装为Cypress自定义命令：

1. 在cypress/support/commands.js中添加如下代码：

// 加缓存逻辑，保证所有调用拿到的是同一套参数，不需要缓存可以删掉相关逻辑
let cachedAffiliateBody = null
Cypress.Commands.add('getAffiliateCreateBody', (refresh = false) => {
  if (refresh || !cachedAffiliateBody) {
    cachedAffiliateBody = {
      "address": Random.address,
      "address_complement": Random.address_complement,
      "address_city": Random.address_city,
      "address_number": `${Random.address_number}`,
      "address_district": Random.address_district,
      "address_state": Random.address_state,
      "cep": `${Random.cep}`,
      "cnpj": Random.cnpj,
      "company_name": Random.company_name,
      "headquarters": fAffiliate.headquarters[1],
      "ie": `${Random.ie}`,
      "phone": Random.phone,
      "rntrc": `${Random.rntrc}`,
      "status": fAffiliate.status[0],
      "trading_name": Random.trading_name
    }
  }
  return cachedAffiliateBody
})

2. 任意测试文件中调用方式：

cy.getAffiliateCreateBody().then(body => {
  cy.request({
    url: "/api/affiliate/create",
    method: "POST",
    headers: {
      Authorization: `bearer ${access_token}`,
    },
    body: body
  })
})

注意事项 #

如果个别请求需要修改部分字段，不要直接修改原变量，避免影响其他复用该Body的请求，使用对象扩展运算符生成新对象即可：

// 仅修改status字段，其余字段和原Body一致
const modifiedBody = {
  ...affiliateCreateBody,
  status: fAffiliate.status[1]
}
