「HarmonyOS Next」error：上传文件"responseCode":17,"message":"Http protocol error"

使用IDE：

DevEco Studio NEXT Developer Beta1

Build Version: 5.0.3.403, built on June 20, 2024

编程环境：

API 12 Beta1

省流

Header头设置方式为 header: {'Content-Type': ''} ，用于覆盖 harmonyOS 默认的Header参数'Content-Type':'application/json'；

let uploadConfig: request.UploadConfig = {
  url: url,
  header: {'Content-Type': ''},
  method: http.RequestMethod.PUT,
  files: files,
  data:[]
}

详细的分析历程

根据官方文档进行上传文件调试：

返回的报文和错误信息如下：

查询API：

header receive 打印出来的错误码是403，就是参数的问题；

查询到gitee的官方参考文档：

就是这个上传会默认把Content-Type设置为application/json，需要覆盖它，让后台自己判定内容格式就好；有人可能就会写成以下的形式，但是并没有卵用；


// 上传任务配置项
let header = new Map<Object, string>();
header.set('Content-Type', '');

正确的覆盖格式是：

let uploadConfig: request.UploadConfig = {
  url: url,
  header: {'Content-Type': ''},
  method: http.RequestMethod.PUT,
  files: files,
  data:[]
}

运行代码，解决问题；
