Facebook API错误100 - 无效链接 [英] Facebook API Error 100 - invalid link
问题描述
我正在使用Facebook API在我的Rails应用程序中创建一个发送对话框。我只是使用Facebook在Javascript中推荐的格式（作为HTML中的脚本）。
I am using the Facebook API to create a Send Dialog in my Rails App. I just use the format that Facebook recommends in a Javascript (as a script in HTML).
我的问题是我得到一个：
My problem is that I get an:
API Error code 100, invalid parameter, link URL not properly formatted
如下：
<script>
function detail(friend_id, user_name, restaurant_name, restaurant_id, articles){
// assume we are already logged in
FB.init({appId: '<%= Facebook::APP_ID.to_s %>', xfbml: true, cookie: true});
FB.ui({
to: friend_id,
method: 'send',
name: user_name +' needs more details about '+ restaurant_name,
picture: 'http://fb-logo-75.png',
link: "<%= Facebook::SITE_URL%>restaurants/"+restaurant_id,
description: '<b>'+user_name + ' needs your help.</b> Add some color to your review of <b>'+restaurant_name+'</b> and help '+articles["object"]+' decide if he should eat there.'
});
}
</script>
请注意：
a） Facebook :: SITE_URL根据环境而变化。你可能认为这是一个localhost问题。然而，当我整合网站URL（这是一个有效的网站，不同于localhost）的值时，我仍然收到错误。然而，这个链接（对我的Heroku
的应用程序）肯定是有效的。
a) The Facebook::SITE_URL changes depending on the environment. You may think this is a localhost problem. However when I integrate the value of the website URL (which is a valid website, unlike localhost) I still get an error. Yet that link (to my app on Heroku ) is definitely functioning.
b）当我发布feed，无论是从本地主机还是在生产中，我不会有错误。问题似乎局限于发送对话框。
b) When I post to feed, whether from localhost or in production, I don't get an error. The problem seems confined to the Send Dialog.
c）当我放入另一个URL，如 http://www.cnn.com 我没有收到错误。
这是在页面上如何调用方法：
c) when I put in another URL such as http://www.cnn.com I don't get an error. Here is how the method is called on the page:
<li class = "flat_list_item"><button id="detail_friend" onclick='detail(<%= review.user.fb_id.to_s %>, "<%= @current_user.first_name.to_s %>",
"<%= review.restaurant.name.to_s %>", <%= review.restaurant.id %>,<%= @current_user.gender_article.to_json %>)'>Tell me more</button></li>
注意：User.gender_article是一个黑客，提供他/他/他，如果用户是男性，如果用户是女性，她/她/她的。
NOTE: User.gender_article is a hack that provides "his/him/he if the user is male, "her/her/hers if the user is female.
这是客户端如何翻译：
HTML：
<button id="detail_friend" onclick="detail(XXXX, "Laurent","Refuge", 227,{"subject":"he","possess":"his","object":"him"})">Tell me more</button>
这就是客户端脚本的样子：
And this is what the script looks like on the client side:
function detail(friend_id, user_name, restaurant_name, restaurant_id, articles){
// assume we are already logged in
FB.init({appId: 'XXXX', xfbml: true, cookie: true});
FB.ui({
to: friend_id,
method: 'send',
name: user_name +' needs more details about '+ restaurant_name,
picture: 'http://fb-logo-75.png',
link: 'http://powerful-woodland-3700.herokuapp.com',
description: '<b>'+user_name + ' needs your help.</b> Add some color to your review of <b>'+restaurant_name+'</b> and help '+articles["object"]+' decide if he should eat there.'
});
}
请注意，此链接实际上是一个功能链接（尽管有很多错误 - 但是它存在并链接到实际的网站）
Note that this link actually is a functional link (albeit with a lot of bugs - but it exists and links to an actual website)
推荐答案
它必须是绝对网址（例如： http://domain.com/path/to/image.png），不能位于Facebook的CDN上。因此，请将其更改为 http://your_domain.com/path/to/fb-logo -75.png
It must be an absolute url (example: http://domain.com/path/to/image.png) and cannot be located on Facebook's CDN. So change that to http://your_domain.com/path/to/fb-logo-75.png
