这是一个非常愚蠢的问题。我是一个Facebook的Javascript SDK的初学者。 所以我试图使一个用户的配置文件的图像显示 我用这个代码如何使用FB.api（'/ me/picture'）来获取个人资料图片
FB.api('/me', function(response) {
document.getElementById('login').style.display = "block";
document.getElementById('login').innerHTML = '<img src="http://graph.facebook.com/' + response.id + '/picture" />';
});
它工作得很好，但我想了解如何使用FB.api('/me/picture')来显示图像。
FB.api('/me/picture')将返回一个redirect到图像URL，因此这将是没有用的你：作为documentation（阅读部分）中提到
您所使用的方法是有效的。也许this是相关的，但我不知道它是否完全有效。
/me/picture（或/{user id}/picture）返回一个HTTP 301重定向到图像位置，这样你可以直接将其嵌入到一个<img src...
如果你要检索的URL和你自己，你需要用它来专门要求它作为一个现场，通过：
/{user id}?fields=picture
或
/me/?fields=picture
您可以包括其他领域也一样，但我假设你现在只想要这张照片。
`/ me/picture`是否会返回一个url（或一个对象）？你说你可以直接将它嵌入到'

你可以得到的个人资料相片的具体尺寸，以及：
FB.api("/me/picture?width=180&height=180", function(response) {
console.log(response.data.url);
});
见Facebook documentation to see what different picture sizes you can get。
并与登录一个完整的演示在：Get Facebook Profile Picture with Javascript SDK
这是肯定出手，事实证明，与Facebook图形API 2.5一起工作。 这是示例HTML请参阅我在FB.api（）函数中所做的更改。

这很有趣。我想知道fb.api（'me/picture'）有什么用处？非常感谢你回复 – user573451 2011-01-14 16:16:05
@ user573451：好吧，我猜这个api存在于服务器端的目的'$ facebook-> api（'/ me/picture'）;`，就像保存原始图像（也许？ ......但就客户方而言，您是否担心，我不认为它有任何用处，并且您已经在使用正确的方式。 :-) – ifaour 2011-01-14 16:41:04
