Appcelerator Titanium上传到谷歌驱动器 - Javascript中的Rest API - 错误404 [英] Appcelerator Titanium upload to google drive - Rest API in Javascript - Error 404

问题描述

我正在尝试使用 appcelerator 钛将图像上传到谷歌驱动器.我有 OAuth 并且我有一个有效的 access_token.

Im trying to upload an image to google drive using appcelerator titanium. I have got OAuth and i have an access_token which is valid.

不幸的是，当我尝试上传图片时，出现 404 http 错误.

Unfortunately when i try and upload the image i get a 404 http error.

function Upload(blob){
Titanium.API.info(googleAuth.getAccessToken());
const boundary = '-------314159265358979323846';
const delimiter = "\r\n--" + boundary + "\r\n";
const close_delim = "\r\n--" + boundary + "--";

var request = Ti.Network.createHTTPClient({

onload : function(e) {

alert(this.requestText); },

    onerror : function(e) {
    Titanium.UI.createAlertDialog({
    title : 'Error',
    message : 'unable to upload' + JSON.stringify(e)
    }).show();
    },
    timeout : 60000

});

var metadata = {
    'title' : "image1.png",
    'mimeType': 'application/json',
};

var mediaRequestBody = 
 delimiter +
    'Content-Type: application/json\r\n\r\n' +
    JSON.stringify(metadata) +
    delimiter +
    blob +
    close_delim;

    var uploadRequest = {
    'headers': {
      'Content-Type': 'multipart/mixed; boundary="' + boundary + '"',
      'access_token' : googleAuth.getAccessToken()
    },
    'body': mediaRequestBody};



var url = 'https://www.googleapis.com/upload/drivev2/files?uploadType=multipart';
request.open("POST", url);
request.send(uploadRequest);

}

我通过的Blob"是通过以下方式检索的:

The 'Blob' i pass through is retrieved by doing:

var f = Titanium.Filesystem.getFile(Titanium.Filesystem.applicationDataDirectory,filename);
f.write(image);
var url = f.nativePath;
var blob = f.read();

我认为很接近，但这可能是我的 http 请求.

I think close but it's probably my http request.

谢谢.

这是我 jsonified 的错误

推荐答案

我以前也遇到过同样类型的问题，以下是我解决它的方法.

I was also facing the same type of issue sometime back and following is how I was able to solve it.

考虑到我有:

• blob 我必须上传的图像.
• 访问令牌是 google api 所需的.
• 我使用的范围是:

• blob of the image which I have to upload.
• Access token required for the google api's.
• Scope which I used is :

1. https://www.googleapis.com/auth/drive
2. https://www.googleapis.com/auth/drive.appdata
3. https://www.googleapis.com/auth/drive.file

步骤 1: 将 blob 图像转换为 base64 编码的字符串.

Step 1: Convert blob image to base64 encoded string.

var base64image = Ti.Utils.base64encode(blobData);

第 2 步:创建请求正文以将图像上传到驱动器.

Step 2: Create the request body to upload image to drive.

var reqBody = '--foo_bar_baz\nContent-Type: application/json; charset=UTF-8\n\n{"title": "' + myFileName + '"}\n--foo_bar_baz\nContent-Type: image/jpeg\nContent-Transfer-Encoding: base64\n\n' + base64image + '\n--foo_bar_baz--';

第 3 步:为请求设置必要的标头.

Step 3: Set the necessary headers for the request.

client.setRequestHeader('Authorization', "Bearer " + myAccessToken); 
client.setRequestHeader('Content-Type', 'multipart/related; boundary="foo_bar_baz"' );  

基本片段:

function upLoadFile(myAccessToken) {
    var base64image = Ti.Utils.base64encode(blobData); //convert blob to base64 encoded string

    var myFileName = "MyImage.png";
    var reqBody = '--foo_bar_baz\nContent-Type: application/json; charset=UTF-8\n\n{"title": "' + myFileName + '"}\n--foo_bar_baz\nContent-Type: image/jpeg\nContent-Transfer-Encoding: base64\n\n' + base64image + '\n--foo_bar_baz--';
    var url = "https://www.googleapis.com/upload/drive/v2/files";
    var client = Ti.Network.createHTTPClient({
        onload : function(e) {
            Ti.API.info("Received text: " + this.responseText);
            alert('success');
        },
        onerror : function(e) {
            Ti.API.debug(e.error);
            alert('error');
        },
        timeout : 100000000
    });
    client.open("POST", url);
    client.setRequestHeader('Authorization', "Bearer " + myAccessToken); 
    client.setRequestHeader('Content-Type', 'multipart/related; boundary="foo_bar_baz"' ); 
    client.send(reqBody);
}

PS:此答案使用 Drive API v2，另请参阅管理上传上的云端硬盘文档.

P.S : This answer uses Drive API v2, also see Drive docs on Manage Upload.
