uni-app unicloud会截断请求数据不能完整获取post请求里面的数据

操作步骤：

const {
  handleDeliveryStatusUpdate,
  handleSfCancel,
  handleOrderCompletion,
  handleOrderException,
  handleRiderRecall
} = require('../utils/handlers.js');

module.exports = {
  /**
   * 处理顺丰同城回调（主入口方法）
   * @param {Object} params - 包含GET参数的对象
   */
  async handleCallback(params) {
    try {
      // 获取HTTP请求信息
      let httpInfo = this.getHttpInfo();
      let bodyStr = httpInfo.body;
      let bodyParams = {};
      let receivedSign = params.sign
      console.log("bodyStr原始数据", bodyStr)
      console.log("sign", receivedSign)
    } catch (error) {
      console.error(error);
    }
  }
}

bug描述：

云函数url化 的请求的post的请求经纬度位数过多，unicloud 得到的数据会被截断，数据如下，导致验签不通过。

这个问题是由于UniCloud在处理POST请求数据时，对浮点数进行了精度截断导致的。具体来说，经纬度数据中的小数部分被截断，导致验签失败。

解决方案：

  1. 在接收数据时，直接获取原始字符串进行处理：
let bodyStr = httpInfo.body.toString(); // 确保获取原始字符串
let bodyParams = JSON.parse(bodyStr); // 自行解析JSON
  1. 或者使用Buffer方式处理：
let bodyBuffer = Buffer.from(httpInfo.body);
let bodyStr = bodyBuffer.toString('utf8');
  1. 如果仍然有问题，可以尝试修改云函数配置：
// cloudfunctions.json
{
  "memorySize": 256,
  "timeout": 5,
  "triggers": [
    {
      "url": true,
      "type": "http",
      "config": {
        "method": "POST",
        "bodyType": "raw"  // 确保使用原始数据格式
      }
    }
  ]
}
