HarmonyOS 远场通信服务双向证书校验时报证书格式错误

对于crt格式的证书文件，rcp请求中除了传入content证书内容，还需要传入key字段即证书对应的密钥文件地址如key: “/path/dir/”，请传入必要字段后再次尝试。

可参考以下示例调用saveFile函数把raw路径下的文件发到手机相关路径下，再配置key: filesDir + ‘/client.key’：

const getRawFileContent = (ctx: Context, file: string) : string => {
  let buffer = ctx.resourceManager.getRawFileContentSync(file).buffer
  return String.fromCharCode(...new Uint8Array(buffer))
}

let context = getContext(this)
let filesDir = context.filesDir
function saveFile(fn: string) {
  let file = fs.openSync(filesDir + '/' + fn, fs.OpenMode.READ_WRITE | fs.OpenMode.CREATE)
  let clientContent = context.resourceManager.getRawFileContentSync(fn)
  fs.writeSync(file.fd, clientContent.buffer)
  fs.fsyncSync(file.fd)
  fs.closeSync(file)
}
saveFile('client.p12')

完整的demo示例请参考如下代码：

import { BusinessError } from '@ohos.base';
import { hilog } from '@kit.PerformanceAnalysisKit';
import { rcp } from "@kit.RemoteCommunicationKit";
import fs from '@ohos.file.fs';

const getRawFileContent = (ctx: Context, file: string) : string => {
  let buffer = ctx.resourceManager.getRawFileContentSync(file).buffer
  return String.fromCharCode(...new Uint8Array(buffer))
}

let context = getContext(this)
let filesDir = context.filesDir
function saveFile(fn: string) {
  let file = fs.openSync(filesDir + '/' + fn, fs.OpenMode.READ_WRITE | fs.OpenMode.CREATE)
  let clientContent = context.resourceManager.getRawFileContentSync(fn)
  fs.writeSync(file.fd, clientContent.buffer)
  fs.fsyncSync(file.fd)
  fs.closeSync(file)
}
saveFile('dck01.crt')
saveFile('private.key')

const selfDefinedRemoteValidation = (context: rcp.ValidationContext) => {
  console.log('context')
  return true
}

@Entry
@Component
struct Index {
  @State message: string = '发送请求';

  async loadData() {
    let HOST = "https://xxx"
    let request = new rcp.Request(HOST, 'POST')
    request.headers = { 'Content-Type': 'application/json' }
    request.content = `{"cywallid":"harmonyos3-f42f-4585-9bdb-69a99d6aa0e5","pubkey":"123456","token":"token-owner-01"}`
    request.configuration = {
      security: {
        remoteValidation: selfDefinedRemoteValidation,
        certificate: {
          content: getRawFileContent(getContext(this), 'dck01.crt'),
          key: filesDir + '/private.key',
          type: 'PEM',
        },
      }
    };

    let session = rcp.createSession()
    session.fetch(request).then((response:rcp.Response) => {
      if (response.statusCode == 200) {
        //hilog.info(0x0000, 'wsrequest', 'get success %{public}s', response.toString())
      }
      hilog.info(0x0000, 'wsrequest', 'get fail %{public}d', response.statusCode)
    }).catch((err: BusinessError) => {
      console.info('get error:' + JSON.stringify(err));
    })
  }

  build() {
    Column() {
      Text(this.message)
        .fontSize('34fp')
        .onClick(() => {
          this.loadData()
        })
    }
    .justifyContent(FlexAlign.Center)
    .height('100%')
    .width('100%')
  }
