微信小程序封装request请求的详细过程

// utils/request.js
const app = getApp();
function requestWithToken(url, method = 'GET', data = {}) {
    return new Promise((resolve, reject) => {
        // 发送请求
        wx.request({
            url: app.globalData.position + url,
            header: {
                "Content-Type": "application/x-www-form-urlencoded"
            },
            method: method,
            data: data,
            success: res => {
                if (res.statusCode === 200) {
                    resolve(res.data);
                } else {
                    // 其他错误处理
                    wx.showToast({
                        title: '请求失败，请稍后重试',
                        icon: 'none'
                    });
                    reject(new Error('Request failed'));
                }
            },
            fail: err => {
                reject(err);
            }
        });
    });
}
// 导出封装的请求函数
module.exports = {
    requestWithToken
};

//封装的请求方法
requestWithToken('Homepage/sel_YearInfo', 'POST', formData)
.then(response => {
    console.log('Form submitted successfully:', response);
    that.setData({
        monthinfo:response.info
    })
})
.catch(error => {
    console.error('Error submitting form:', error);
    // 处理错误
});

requestWithToken('Homepage/sel_YearInfo', 'GET')
      .then(response => {
          console.log('Protected resource:', response);
          // 处理响应数据
      })
      .catch(error => {
          console.error('Error:', error);
          // 处理错误
      }
