通过网页

Question

我使用Google提供的文档here尝试将图片从网页上传到Google云端存储。我认为存储设置正确，我认为我已经得到了正确的值。

使用时，图像会被识别，但由于某种原因，图片无法上传。我不确定它是代码还是环境的设置方式。此外，没有报告错误消息。我知道图像是通过事件进入功能的。

javascript是......

        /**
         * Google Cloud Storage API request to insert an object into
         * your Google Cloud Storage bucket.
         */
        function insertObject(event) {
            try {
                //var MyFile = document.getElementById("take-picture").files;
                var fileData = event.target.files[0];
                //var fileData = document.getElementById("take-picture").files;
            } 
            catch(e) {
                //'Insert Object' selected from the API Commands select list
                //Display insert object button and then exit function
                //filePicker.style.display = 'block';
                return;
            }
          var boundary = '-------314159265358979323846';
          var delimiter = "\r\n--" + boundary + "\r\n";
          var close_delim = "\r\n--" + boundary + "--";

            var reader = new FileReader();
            reader.readAsBinaryString(fileData);
            reader.onload = function(e) {
                var contentType = fileData.type || 'application/octet-stream';
                var metadata = {
                    'name': fileData.name,
                    'mimeType': contentType
                };

                var base64Data = btoa(reader.result);
                var multipartRequestBody =
                  delimiter +
                  'Content-Type: application/json\r\n\r\n' +
                  JSON.stringify(metadata) +

                try{

                    //Store the name of the inserted object 
                    object = fileData.name;         
                }
                catch(e) {
                    alert('An error has occurred: ' + e.message);
                }
            }
        }

Answer 1

不太确定问题出在哪里。

但在我的工作代码中，我正在使用

var metadata = {
    'title': fileData.fileName || fileData.name,
    'parents': [{
    "kind": "drive#fileLink",
            "id": folderId
    }],
    'mimeType': contentType
};

因此，您的代码可能会丢失文件夹的ID

API请求：

var request = gapi.client.request({
        'path': '/upload/drive/v2/files',
        'method': 'POST',
        'params': {'uploadType': 'multipart'},
        'headers': {
          'Content-Type': 'multipart/mixed; boundary="' + boundary + '"'
        },
        'body': multipartRequestBody
});

FYR。
