如何将 Dropbox 中的所有文件保存到我的 HTML 页面
How to get all Files Save in Dropbox to my HTML Page
我已经使用 Javascript 将图像保存在 Dropbox 中
document.forms.newsletter.addEventListener('submit', function
cb(evt) {
//evt.preventDefault()
// API key from here: https://dropbox.github.io/dropbox-api-v2-
explorer/#files_upload
// need to consider how this gets secured
var TOKEN = ''
var dir = 'blackground/'
var file = document.getElementById('file').files[0]
var promise = new Promise(function (resolve, reject) {
// Dropbox requires application/octet-stream
var xhr = new XMLHttpRequest();
xhr.onload = function() {
if (xhr.status === 200) {
resolve(JSON.parse(xhr.response));
}
else {
reject(xhr.response || 'Unable to upload file');
}
};
xhr.open('POST',
'https://content.dropboxapi.com/2/files/upload');
xhr.setRequestHeader('Authorization', 'Bearer ' + TOKEN);
xhr.setRequestHeader('Content-Type', 'application/octet-
stream');
xhr.setRequestHeader('Dropbox-API-Arg', JSON.stringify({
path: '/' + dir + file.name,
mode: 'add',
autorename: true,
mute: false
}));
xhr.send(file);
})
promise
.then(function (result) {
// Save dropbox response to form
document.getElementById('dropbox').value =
JSON.stringify(result)
// Submit form on successful upload
evt.target.submit()
})
.catch(function (err) {
console.log('a');
})
return false
})
它工作正常。但我想使用 Javascript 和 ajax 检索每个图像以在我的网页中显示它。怎么做到的?
我阅读了这份文档 https://www.dropbox.com/developers-v1/core/docs#files-GET,我们可以使用 Get Verb 实现它。
我已经为 API 创建了一个 Get 以像这样获取所有图像
$.ajax({
method: "GET",
url: "https://content.dropboxapi.com/1/files/auto/blackground",
dataType: "json",
ContentType:"application/octet-stream",
Authorization:"Bearer token"
});
我收到这个错误
{error: "Authentication failed"}
error
:
"Authentication failed"
blackground 是所有图片所在的文件夹
有什么可以帮忙的
现在可以正常使用了。我是这样做的。 Token 是我的 Dropbox 令牌。
var token = '';
var xhr = new XMLHttpRequest();
xhr.responseType = 'blob';
xhr.onreadystatechange = function () {
if (xhr.readyState === 4 && xhr.status === 200) {
var imageUrl = (window.URL || window.webkitURL).createObjectURL(xhr.response);
// display, assuming <img id="image"> somewhere
document.getElementById('image').src = imageUrl;
// download via the download attribute: limited browser support
var a = document.createElement('a');
//a.download = 'test.png';
//a.href = imageUrl;
//a.click();
}
};
xhr.open('POST', 'https://content.dropboxapi.com/2/files/download');
xhr.setRequestHeader('Authorization', 'Bearer ' + token);
xhr.setRequestHeader('Dropbox-API-Arg', JSON.stringify({ path: '/blackground/blackground_logo.jpg' }));
xhr.send();
