Question

我一直致力于G驱动API，并使用JavaScript for Windows 8上传，下载文件和文件夹的删除和更新。我遇到的两个问题是;

当我上传文件或文件夹时，会上传标题为“UNTITLED”，你能告诉我我做错了吗？我的要求是这样的;

WinJs.xhr ({
      url: 'https://www.googleapis.com/upload/drive/v2/files?uploadType=media', 
    type: "post", 
    headers: { "Authorization": "Bearer " + accessToken, },     

data: { "mimeType": "application/vnd.google-apps.folder", "title": "sampleFolder2" } }).then

(function (success) { 
   var response = JSON.parse(success.response); 
     },    
    function (error) { 
    console.log(error);

   });

当我下载文件时，我得到一个加密或一些独特类型的响应，就像我下载JPEG图像一样，我在响应文本中得到了JFIF。你能告诉我为什么吗？我不能把文件下载到我的磁盘..？

以下是使用media为uploadtype插入文件的完整功能。

function insertFile(accessToken) {

        var openPicker = new Windows.Storage.Pickers.FileOpenPicker();
        openPicker.viewMode = Windows.Storage.Pickers.PickerViewMode.thumbnail;
        openPicker.fileTypeFilter.replaceAll([".png", ".jpg", ".jpeg", ".txt"]);
        openPicker.pickSingleFileAsync().then(function (file) {
            if (file) {
                var tMeta = {
                    title: file.name,
                    mimeType: file.contentType,
                    description: "xyz description."
                };
                WinJS.xhr({
                    url: 'https://www.googleapis.com/upload/drive/v2/files?uploadType=media',
                    type: "post",
                    headers: {
                        "Authorization": "Bearer " + accessToken,
                        'Content-Type': file.contentType,
                        'Title': file.name
                    },
                    body: tMeta,

                }).then(function (success) {
                    var response = JSON.parse(success.response);
                    var file1 = response;
                    secondRequest(accessToken, file1 , file);


                }, function (error) {
                    var x = 4;
                });

            }
        });


    }

   function secondRequest(accessToken, file1,file) {

       var x = 2;


       var tMeta = {
           title: file.name,
           mimeType: file1.mimeType,
          // description: "xyz description."
       };

       var URL = 'https://www.googleapis.com/upload/drive/v2/files/' + file1.id + '?uploadType=media'
       WinJS.xhr({
           url: URL,
           type: "put",
           headers: {
               "Authorization": "Bearer " + accessToken,
               'Content-Type': file1.mimeType,
               'Title': file.name
           },
           body: tMeta,

           data: MSApp.createFileFromStorageFile(file)


       }).then(function (success) {

           var secondResponse = JSON.parse(success.response);

           var z = 3;
       }), function (error) {

           var x = 3;
       }


   }

如果您要使用该文件上传元数据，则需要实施multipart上传。它是在https://developers.google.com/drive/manage-uploads#multipart

上解释的

使用Google Drive API javascript上传或更新文件时标题为“无标题”？
