Appcelerator钛上传到谷歌驱动器 - 其余API在JavaScript - 错误404 [英] Appcelerator Titanium upload to google drive - Rest API in Javascript - Error 404
本文介绍了Appcelerator钛上传到谷歌驱动器 - 其余API在JavaScript - 错误404的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有OAuth，并且有一个有效的access_token。
不幸的是，当我尝试上传图片时，我得到一个404 http错误。
函数上传（blob）{
Titanium.API.info（googleAuth.getAccessToken（））;
const boundary ='------- 314159265358979323846';
const delimiter =\r\\\
--+ boundary +\r\\\
;
const close_delim =\r\\\
--+ boundary + - ;
$ b var request = Ti.Network.createHTTPClient（{
onload：function（e）{
alert（this.requestText）;}，
onerror：function（e）{
Titanium.UI.createAlertDialog（{
title：'Error'，
message：'无法上传'+ JSON。 stringify（e）
}）。show（）;
}，
timeout：60000
}）;
var metadata = {
'title'：image1.png，
'mimeType'：'application / json'，
};
var mediaRequestBody =
分隔符+
'Content-Type：application / json\r\\\
\r\\\
'+
JSON.stringify （元数据）+
分隔符+
blob +
close_delim;
var uploadRequest = {
'headers'：{
'Content-Type'：'multipart / mixed; border =''+ border +''，
'access_token'：googleAuth.getAccessToken（）
}，
'body'：mediaRequestBody};
var url ='https://www.googleapis.com/upload/drivev2/files?uploadType=multipart';
request.open（POST，url）;
request.send（uploadRequest）;
}
var f = Titanium.Filesystem.getFile（Titanium.Filesystem.applicationDataDirectory，filename）;
f.write（image）;
var url = f.nativePath;
var blob = f.read（）;
我觉得很近，但可能是我的http请求。
谢谢。！
解决方案
考虑到我有以下情况：
-
blob我必须上传图片。 - 我使用的范围是：
- https://www.googleapis.com/auth/drive
- < a href =https://www.googleapis.com/auth/drive.appdata =nofollow> https://www.googleapis.com/auth/drive.appdata
- https://www.googleapis.com/auth/drive.file
第1步 g>将blob图像转换为base64编码的字符串。
var base64image = Ti.Utils.base64encode（blobData）;
第2步：创建要将图片上传到驱动器的请求正文
var reqBody ='--foo_bar_baz\\\
Content-Type：application / json; charset = UTF-8 \\\
\\\
{title：'+ myFileName +'} \\\
- foo_bar_baz\\\
Content-Type：image / jpeg\\\
Content-Transfer-Encoding：base64\ n \ n'+ base64image +'\\\
- foo_bar_baz--';
第3步：为请求设置必要的标头。
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）; //将blob转换为base64编码的字符串
var myFileName =MyImage.png;
var reqBody ='--foo_bar_baz\\\
Content-Type：application / json; charset = UTF-8 \\\
\\\
{title：'+ myFileName +'} \\\
- foo_bar_baz\\\
Content-Type：image / jpeg\\\
Content-Transfer-Encoding：base64\ n \ n'+ base64image +'\\\
- 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）;
这个答案使用 Drive API v2 ，另请参阅在管理上传。
希望它有帮助。
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.
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);
}
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();
I think close but it's probably my http request.
Thanks.!
This is the error i get jsonified
解决方案 I was also facing the same type of issue sometime back and following is how I was able to solve it.
Considering I have :
blob of the image which I have to upload.- Access token required for the google api's.
- Scope which I used is :
Step 1: Convert blob image to base64 encoded string.
var base64image = Ti.Utils.base64encode(blobData);
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--';
Step 3: Set the necessary headers for the request.
client.setRequestHeader('Authorization', "Bearer " + myAccessToken);
client.setRequestHeader('Content-Type', 'multipart/related; boundary="foo_bar_baz"' );
The basic snippet :
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);
}
P.S : This answer uses Drive API v2, also see Drive docs on Manage Upload.
Hope it is helpful.
