[英]How to use FB.api('/me/picture') to get profile image
這是一個非常愚蠢的問題。 我是facebook Javascript SDK的初學者。 所以我試圖讓用戶的個人資料圖像顯示我使用了這個代碼
FB.api('/me', function(response) {
document.getElementById('login').style.display = "block";
document.getElementById('login').innerHTML = '<img src="http://graph.facebook.com/' + response.id + '/picture" />';
});
哪個工作正常，但我試圖了解如何使用FB.api('/me/picture')來顯示圖像。
/me/picture （或/{user id}/picture ）返回HTTP 301重定向到圖像位置，以便您可以將其直接嵌入到<img src...
如果您想要檢索URL並自己使用它，您需要通過以下方式專門請求它作為字段：
/{user id}?fields=picture
要么
/me/?fields=picture
你也可以包括其他字段，但我假設你現在只想要照片。
您還可以獲得個人資料照片的特定尺寸：
FB.api("/me/picture?width=180&height=180", function(response) {
console.log(response.data.url);
});
請參閱Facebook文檔，了解您可以獲得的不同圖片尺寸 。
以及登錄的完整演示： 使用Javascript SDK獲取Facebook個人資料圖片
這肯定是拍攝的，證明可以使用facebook圖api 2.5。 這是示例HTML請參閱我在FB.api（）函數中所做的更改。

// This is called with the results from from FB.getLoginStatus().

// Full docs on the response object can be found in the documentation
// for FB.getLoginStatus().
if (response.status === 'connected') {
// Logged into your app and Facebook.
testAPI();
} else if (response.status === 'not_authorized') {
// The person is logged into Facebook, but not your app.
document.getElementById('status').innerHTML = 'Please log ' +
'into this app.';
} else {
// The person is not logged into Facebook, so we're not sure if
// they are logged into this app or not.
document.getElementById('status').innerHTML = 'Please log ' +
'into Facebook.';
}
}
// This function is called when someone finishes with the Login
// Button. See the onlogin handler attached to it in the sample
// code below.
function checkLoginState() {
FB.getLoginStatus(function(response) {
statusChangeCallback(response);
});
}
window.fbAsyncInit = function() {
FB.init({
appId : 'XXXXXXXXXXXX',
cookie : true, // enable cookies to allow the server to access
// the session
xfbml : true, // parse social plugins on this page
version : 'v2.5' // use graph api version 2.5
});
// Now that we've initialized the JavaScript SDK, we call
//FB.getLoginStatus(). This function gets the state of the
// person visiting this page and can return one of three states to
// the callback you provide. They can be:
//
// 1. Logged into your app ('connected')
// 2. Logged into Facebook, but not your app ('not_authorized')
// 3. Not logged into Facebook and can't tell if they are logged into
// your app or not.
//
// These three cases are handled in the callback function.
FB.getLoginStatus(function(response) {
statusChangeCallback(response);
});
};
// Load the SDK asynchronously
(function(d, s, id) {
var js, fjs = d.getElementsByTagName(s)[0];
if (d.getElementById(id)) return;
js = d.createElement(s); js.id = id;
js.src = "//connect.facebook.net/en_US/sdk.js";
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));
// Here we run a very simple test of the Graph API after login is
// successful. See statusChangeCallback() for when this call is made.
function testAPI() {
console.log('Welcome! Fetching your information.... ');
FB.api('/me', function(response) {
