Google云端存储Javascript用法 [英] Google Cloud Storage Javascript Usage
问题描述
我试图使用 JSON API 将图片上传到Google云端存储上的存储桶中>，使用Javascript示例：
Api Javascript示例
i am trying to upload images into buckets on Google Cloud Storage using the JSON API, using the Javascript sample: Api Javascript Sample
我可以上传图片，但它要求我登录我的google帐户。
I am able to upload pictures but it asks me to log in on my google account.
示例中有一个授权按钮，我了解它管理的OAuth凭据。
Tthe sample has an Authorization button, which I understand manages the OAuth credentials.
function checkAuth() {
gapi.auth.authorize({
client_id: clientId,
scope: scopes,
immediate: true
}, handleAuthResult);
}
问题是：
我想要验证，而不需要弹出屏幕，这意味着无需使用Google登录。因为我的客户不知道电子邮件或密码，所以我想要自动。
I want to authenticate without having the pop up screen, that means without login in with Google. Because my client doesn't know the email or password, I want it to be automatically.
如何实现？
谢谢！

因此，接下来Brandon的回答我做了以下：
So following Brandon's answer i have done the following:
我已经创建了我的策略文档，并且这样签名：
I have created my policy document and signed it like this:
var http = require('http');
var fs = require('fs');
var crypto = require('crypto');
var express = require('express');
var app = express();
var p12ToPem = require("./node_modules/p12-to-pem/p12ToPem.js");
var p12File = fs.readFileSync("./KEY.p12");
var pemKey = p12ToPem(p12File, "notasecret");
var policyJson={"expiration": "2050-06-16T11:11:11Z",
"conditions": [["starts-with", "$key", "" ],
{"acl": "bucket-owner-read" },
{"bucket": "my-bucket'name"},
{"success_action_redirect":"http://www.example.com/success_notification.html" },
["eq", "$Content-Type", "image/jpeg" ],
["content-length-range", 0, 1000000]
]
};
var policyJson64 = new Buffer(''+policyJson).toString('base64');
var sign = crypto.createSign('RSA-SHA256');
sign.update(policyJson64);
var sig = sign.sign(pemKey, 'base64')
console.log("policyJson64:"+policyJson64);
console.log("sig:"+sig);
我的帖子形式如下：
<form action="http://my-bucket-name.storage.googleapis.com" method="post" enctype="multipart/form-data">
<input type="text" name="key" value="">
<input type="hidden" name="bucket" value="my-bucket-name">
<input type="hidden" name="Content-Type" value="image/jpeg">
<input type="hidden" name="GoogleAccessId" value="884257827820-so77htet9tafrcjjp83m7api9lh12qsn@developer.gserviceaccount.com">
<input type="hidden" name="acl" value="bucket-owner-read">
<input type="hidden" name="success_action_redirect" value="http://www.example.com/success_notification.html">
<input type="hidden" name="policy" value="DONT KNOW WHAT TO PUT HERE">
<input type="hidden" name="signature" value="NEITHER HERE">
<input name="file" type="file">
<input type="submit" value="Upload">
javascrypt我似乎无法找出什么进入政策和什么到签名，是！我已经阅读API，但不清楚在这些2个输入的内容。
我试图把策略输入PolicyJson64和sig的值。我已经尝试把签名输入sig和pemKey的值。
No matter the combinations obtained in the javascrypt I cant seem to figure out what goes into policy and what into signature,and YES! I have read the API but it is not clear on what goes in those 2 inputs.. I have tried putting on the policy input the value of PolicyJson64 and sig as well. And I have tried putting on the signature input the value of sig and pemKey too.
我得到这个错误：
<Error>
<Code>SignatureDoesNotMatch</Code>
<Message>
The request signature we calculated does not match the signature you provided. Check your Google secret key and signing method.

我应该放什么？

推荐答案
由于Google云端存储没有上传图片的简单方法（2014）使用Amazon Web Services甚至带有一个NodeJS示例代码。使用方便简单。
As Google Cloud Storage doesnt have a simple way to upload an image (2014), I ended up using Amazon Web Services which even comes with a NodeJS Sample Code. Easy and simple to use.
http://aws.amazon.com/es/developers/getting-started/nodejs/
复制示例：
git clone https://github.com/awslabs/aws-nodejs-sample.git
安装：
npm install
执行：
node sample.js
示例带有存储桶使用，甚至将文件存储在存储桶中。所以这将使它。请务必更改您的凭据：
The Sample comes with bucket usage and they even store a file in the bucket. So that will make it. Make sure to change your credentials:
aws_access_key_id = YOUR_ACCESS_KEY_ID
aws_secret_access_key = YOUR_SECRET_ACCESS_KEY
干杯！
