我正在 vue js 中使用自定义裁剪选项制作图像上传组件。裁剪后的版本在我的状态中保存为 Base64 字符串。就是这个：

现在我尝试使用 post request API 将此图像发送到我的 Node js 服务器。在 Postman 中，我以这种方式在正文中选择“raw”和“json”来编写正文：

{
        "image" : "data:image/png;base64,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.....
}

请求未检测到正文中的此 json 数据并返回错误：

{
    "image": "\"image\" is required"
}

还尝试了这样的form_data发送方法：

var axios = require('axios');
      var FormData = require('form-data');
      // var fs = require('fs');
      var data = new FormData();
      data.append('image', formdata.logoFinalImage);

      var config = {
        method: 'post',
        url: myurl,
        headers: {
          'Authorization': this.state.token,
          'Content-Type': 'application/json'
        },
        data: data
      };

      axios(config)
        .then(function (response) {
          console.log(JSON.stringify(response.data));
        })
        .catch(function (error) {
          console.log(error); …
