我一直在尝试从我的网站将文件上传到机架空间存储。我已按照以下 api 指南创建将文件上传到 rackspace 的表单。 http://docs.rackspace.com/files/api/v1/cf-devguide/content/FormPost-d1a555.html 第 7.2、7.2.1 和 7.2.2 节
如果我进行正常的表单提交,它完全可以正常工作。该文件被上传到机架空间存储并返回状态 201 和空白消息。我检查了容器中的文件并成功上传。
但是现在问题来了,当我尝试使用 Blueimp jQuery 文件上传插件集成进度条时。
这是我初始化文件上传插件的代码
$(function () {
'use strict';
// Initialize the jQuery File Upload widget:
$('#fileupload').fileupload({maxChunkSize: 10000000});
if (window.location.hostname === 'blueimp.github.com') {
// Demo settings:
$('#fileupload').fileupload('option', {
url: '//jquery-file-upload.appspot.com/',
maxFileSize: 5000000,
acceptFileTypes: /(\.|\/)(gif|jpe?g|png)$/i,
process: [
{
action: 'load',
fileTypes: /^image\/(gif|jpeg|png)$/,
maxFileSize: 20000000 // 20MB
},
{
action: 'resize',
maxWidth: 1440,
maxHeight: 900
},
{
action: 'save'
}
]
});
// Upload server status check for browsers with CORS support:
if ($.support.cors) {
$.ajax({
url: '//jquery-file-upload.appspot.com/',
type: 'HEAD'
}).fail(function () {
$('<span class="alert alert-error"/>')
.text('Upload server currently unavailable - ' +
new Date())
.appendTo('#fileupload');
});
}
} else {
// Load existing files:
console.log("mukibul");
$('#fileupload').each(function () {
var that = this;
console.log("result1");
$.getJSON(this.action, function (result) {
if (result && result.length) {
console.log("result");
console.log(result);
$(that).fileupload('option', 'done')
.call(that, null, {result: result});
}
});
});
}});
这是上传文件的网络表单

</form>
当我上传任何文件时,它开始正常上传,进度开始按预期显示。在 chrome Inspect->Network 选项卡中,我可以看到对机架空间服务器的两个请求。一个是返回 200 的方法 OPTIONS,另一个是 POST 方法,它一直处于待处理状态,直到进度条达到 100%,但一旦达到 100%,POST 方法的状态就会更改为已取消,并且 jquery 文件上传插件在网页。我无法理解为什么插件会抛出错误。我检查了容器,发现文件上传成功。
我使用 curl 在机架空间中设置了 CORS 所需的所有标头。但不确定我做错了什么。任何解决问题的帮助将不胜感激。
注意:我正在为应用程序使用 spring mvc。
谢谢, 穆基布尔
