将图像转换为Blob以存储在phpmyadmin中

Question

我有一个具有基本注册页面的react应用，其中一部分是允许用户上传个人资料照片。我在这里阅读了许多有关在服务器端发送图像的答案，但是没有一个对我有用。克服C:\\fakepath\\img-name。我是否可以将图像转换为缓冲数组，以与其他输入字段一起发送？

这是我将数据发送到api的方式：

handleSubmit(){
    let fname     = this.state.fname;
    let lname     = this.state.lname;
    let email     = this.state.email;
    let password  = this.state.password;
    let mentor    = this.state.mentor;
    let mentee    = this.state.mentee;
    let photo     = this.state.photo
    let interest1 = this.state.interest1;
    let interest2 = this.state.interest2;
    let interest3 = this.state.interest3;
    let course    = this.state.course;

    const requestBody = {
      fname: fname,
      lname: lname,
      email: email,
      password: password,
      photo: photo,
      mentor: mentor,
      mentee: mentee,
      interest1: interest1,
      interest2: interest2,
      interest3: interest3,
      course: course
    }
    const config = {
    headers: {
      'Content-Type': 'application/x-www-form-urlencoded'
    }}
    if(this.checkValidation()) {

      request.post("/register",qs.stringify(requestBody),config)
             .then(result => this.setState({submitStatus: result.status}))
             .catch(err   => console.log(err))
    }
  }

当我将其提交到api服务器时，我得到了：

{ fname: 'Naruto',
  lname: 'Uzumaki',
  email: 'Naruto@konoha.com',
  password: 'Hokage',
  mentor: 'on',
  mentee: '',
  interest1: 'Anime',
  interest2: 'Football',
  interest3: 'Gaming',
  course: 'CPSS' }

在此方面的任何帮助将不胜感激！
