将 openId 选择器与 Asp.Net MVC 2 集成时出现问题
我正在尝试使用 openid 选择器 javascript 库来允许 OpenId 登录网站。我正在按照此网站上的说明进行操作,但是我通常不是网络程序员,它不起作用,我不确定为什么。我确信这是相当微不足道的事情,但我看不到它。
问题是没有带有 open Id 位的图像渲染在它应该去的地方,即 I'我假设。这似乎表明应该设置此 div 内容的函数没有运行。
我怀疑剧本。
我已经添加了对 Site.Master 的脚本引用,如下所示:
<script type="text/javascript" src="../../Scripts/jquery-1.4.1.min.js"></script>
<script type="text/javascript" src="../../Scripts/openid-jquery.js"></script>
<script type="text/javascript">
$(document).ready(function () {
alert("document ready"); // <- I added this to verfiy that this is being called
openid.init('openid_identifier');
});
</script>
它似乎在每个页面上调用该函数(显示警报),然后我认为应该调用 openid.init 函数。
这是在 openid-jquery.js
脚本中定义的:
var openid = {
version: '1.2', // version constant
demo: false,
demo_text: null,
cookie_expires: 6 * 30, // 6 months.
cookie_name: 'openid_provider',
cookie_path: '/',
img_path: '../images/',
lang: null, // language, is set in openid-jquery-<lang>.js
signin_text: null, // text on submit button on the form
input_id: null,
provider_url: null,
provider_id: null,
all_small: false, // output large providers w/ small icons
no_sprite: false, // don't use sprite image
image_title: '{provider}', // for image title
init: function (input_id) {
alert("initialising");
providers = $.extend({}, providers_large, providers_small);
var openid_btns = $('#openid_btns');
this.input_id = input_id;
$('#openid_choice').show();
$('#openid_input_area').empty();
var i = 0;
// add box for each provider
for (id in providers_large) {
if (this.all_small) {
openid_btns.append(this.getBoxHTML(id, providers_large[id], 'small', i++));
} else
openid_btns.append(this.getBoxHTML(id, providers_large[id], 'large', i++));
}
if (providers_small) {
openid_btns.append('<br/>');
for (id in providers_small) {
openid_btns.append(this.getBoxHTML(id, providers_small[id], 'small', i++));
}
}
$('#openid_form').submit(this.submit);
var box_id = this.readCookie();
if (box_id) {
this.signin(box_id, true);
}
我再次添加了 alert("initialising");
,它似乎从未被调用。
应该调用这个函数吗?我怎样才能确定为什么这个函数没有被调用?有什么想法吗?
更新:
在文档就绪函数中,我交换了函数的顺序,如下所示:
<script type="text/javascript">
$(document).ready(function () {
openid.init('openid_identifier');
alert("document ready");
});
</script>
现在不会引发警报。这是什么意思?其他功能出了问题吗?我怎么知道它是什么?
更新2:
奇怪。如果我将 openid-jquery.js 文件重命名为其他名称(似乎是任何名称)(例如 openid-jquery.2.js),那么我可以从 open id 脚本中看到警报。
但它似乎只执行警报,而不执行下一行,因为当我稍后添加另一个更改时(即在下一行之后),从未看到第二个警报。也不知道为什么会这样。
更新3: 在 Chrome 中调试后,问题似乎是 providers_large、providers_small
未定义,并
var providers_large;
var providers_small;
在脚本顶部添加: 允许它至少运行并显示警报。但仍然没有图像...我认为需要进一步调查。
I am trying to use the openid selector javascript library to allow OpenId login for a web site. I'm following the instructions on this site, but I'm not usually a web programmer and its not working and I'm not certain why. I'm sure its something fairly trivial but I can't see it.
The problem is that no image with the open Id bits on it is rendered in the place where it should go, which is the <div id="openid_btns"></div>
I'm assuming. This seems to indicate to me that the function which is supposed to set the contents of this div is not being run.
I suspected the scripts.
I have added the script references to the Site.Master as it indicates:
<script type="text/javascript" src="../../Scripts/jquery-1.4.1.min.js"></script>
<script type="text/javascript" src="../../Scripts/openid-jquery.js"></script>
<script type="text/javascript">
$(document).ready(function () {
alert("document ready"); // <- I added this to verfiy that this is being called
openid.init('openid_identifier');
});
</script>
and it seems to call the function on each page (the alert is shown) and it should then, I assume, call the openid.init function.
this is defined in the openid-jquery.js
script:
var openid = {
version: '1.2', // version constant
demo: false,
demo_text: null,
cookie_expires: 6 * 30, // 6 months.
cookie_name: 'openid_provider',
cookie_path: '/',
img_path: '../images/',
lang: null, // language, is set in openid-jquery-<lang>.js
signin_text: null, // text on submit button on the form
input_id: null,
provider_url: null,
provider_id: null,
all_small: false, // output large providers w/ small icons
no_sprite: false, // don't use sprite image
image_title: '{provider}', // for image title
init: function (input_id) {
alert("initialising");
providers = $.extend({}, providers_large, providers_small);
var openid_btns = $('#openid_btns');
this.input_id = input_id;
$('#openid_choice').show();
$('#openid_input_area').empty();
var i = 0;
// add box for each provider
for (id in providers_large) {
if (this.all_small) {
openid_btns.append(this.getBoxHTML(id, providers_large[id], 'small', i++));
} else
openid_btns.append(this.getBoxHTML(id, providers_large[id], 'large', i++));
}
if (providers_small) {
openid_btns.append('<br/>');
for (id in providers_small) {
openid_btns.append(this.getBoxHTML(id, providers_small[id], 'small', i++));
}
}
$('#openid_form').submit(this.submit);
var box_id = this.readCookie();
if (box_id) {
this.signin(box_id, true);
}
again I added the alert("initialising");
which never seems to be called.
Should it be calling this function? How can I determine why this function is not being called? Any ideas?
UPDATE:
in the document ready function i swapped the order of the functions like so:
<script type="text/javascript">
$(document).ready(function () {
openid.init('openid_identifier');
alert("document ready");
});
</script>
and now the alert is not raised. what does this mean? is something going wrong in the other function? how can I tell what it is?
UPDATE 2:
Wierd. If I rename the openid-jquery.js file to something (seemingly anything) else (like openid-jquery.2.js) then I can see the alert from the open id script.
but it only seems to execute the alert and not the next line as when I add another alter later on (ie after the very next line) the 2nd alert is never seen. not sure why that would be either.
UPDATE 3:
After debugging in chrome it seems the problem was that providers_large, providers_small
were not defined and adding:
var providers_large;
var providers_small;
to the top of the script allowed it to at least run and show the alerts. but still no images... further investigation I think.

因此,似乎在说明的第 4 步中,需要更新它以添加英语 javascript 提供程序信息,这是定义
provider_large
的位置,如下所示:so it seems that in step 4 of the instructions it needs to be updated to add the english javascript provider information which is where the
provider_large
is defined, like so:对 Sam 在 1.3 版本中的回答进行了轻微更新。
解压文件:
C:\Blah\openid-selector-1.3\openid-selector\js\openid-en.js
脚本标签:
Slight update to Sam's answer above for version 1.3.
Unzipped Files:
C:\Blah\openid-selector-1.3\openid-selector\js\openid-en.js
Script Tag:
<script type="text/javascript" src="../../Scripts/openid-en.js"></script>
我遇到了同样的问题,检查您的 web.config 并将所有用户的权限添加到这些新目录,然后工作
I had the same problem, check your web.config and add permission to all users to those new directories, and then works
