使用框架: React

复现步骤

发送POST请求

Taro.request({
  url: 'test.php', //仅为示例，并非真实的接口地址
  data: {
    x: '',
    y: ''
  },
method: 'POST',
  header: {
    'content-type': 'application/json' // 默认值
  },
  success: function (res) {
    console.log(res.data)
  }
})

期望结果

request header的content-type为 'application/json'

实际结果

content-type为text/plain

@chenEdgar 你这是设置的请求头为application/json
response header 是由服务端控制的

设置mode:no-cors的缘故
