在 JavaScript 中通过 jQuery 从文本上传文件

var data = new TextEncoder("utf-8").encode("Test");
$.ajax({
    url: 'https://content.dropboxapi.com/2/files/upload',
    type: 'post',
    data: data,
    processData: false,
    contentType: 'application/octet-stream',
    headers: {
        "Authorization": "Bearer <ACCESS_TOKEN>",
        "Dropbox-API-Arg": '{"path": "/test_upload.txt","mode": "add","autorename": true,"mute": false}'
    },
    success: function (data) {
        console.log(data);
    },
    error: function (data) {
        console.error(data);
    }
})

<ACCESS_TOKEN> 应替换为 OAuth 2 访问令牌。
