我有从 Linkedin 中提取我的连接信息的工作代码。 但是，每当我尝试提取位置时，我都会得到奇怪的结果。
此代码有效，但您会在应该位于位置的位置看到“object OBJECT”。
<html lang="en">
<head>
<title>LinkedIn Industries</title>
<script type="text/javascript" src="http://platform.linkedin.com/in.js">
api_key: xxxxxxx
onLoad: onLinkedInLoad
scope: r_network,r_emailaddress,r_fullprofile,r_basicprofile,r_contactinfo
</script>
</head>
<body>
<p>This example demonstrates how to retrieve a user's connections. It also uses the LinkedIn auth events (load, login, logout) to control behavior.</p>
<!-- NOTE: be sure to set onLoad: onLinkedInLoad -->
<script type="text/javascript">
function onLinkedInLoad() {
IN.Event.on(IN, "auth", function() {onLinkedInLogin();});
IN.Event.on(IN, "logout", function() {onLinkedInLogout();});
}
function onLinkedInLogout() {
setConnections({}, {total:0});
}
function onLinkedInLogin() {
// here, we pass the fields as individual string parameters
IN.API.Connections("me")
.fields("id", "firstName", "lastName", "pictureUrl", "publicProfileUrl","location:(name)")
.result(function(result, metadata) {
setConnections(result.values, metadata);
});
}
function setConnections(connections) {
var connHTML = "<ul>";
for (id in connections) {
connHTML = connHTML + "<li><a href=\"" + connections[id].publicProfileURL + "\">";
/* picture url not always there, must be defensive */
if (connections[id].hasOwnProperty('pictureUrl')) {
connHTML = connHTML + "<img align=\"baseline\" src=\"" + connections[id].pictureUrl + "\"></a>";
} else {
connHTML = connHTML + "<img align=\"baseline\" src=\"http://static02.linkedin.com/scds/common/u/img/icon/icon_no_photo_80x80.png\"></a>";
}
connHTML = connHTML + " <a href=\"" + connections[id].publicProfileUrl + "\">";
connHTML = connHTML + connections[id].firstName + " " + connections[id].lastName + "</a>";
connHTML = connHTML + " (Location: " + connections[id].location + ")</li>";
}
connHTML = connHTML + "</ul>";
document.getElementById("connectionsdata").innerHTML = connHTML;
}
</script>
<script type="IN/Login">
<div id="connectionstest">
<p>Current User's Connections:</p>
<div id="connectionsdata"></div>
</div>
</script>
</body>
</html>
主要问题确实存在于 location，在文档中，这应该替换为 location.name，但是，每当我这样做时，我什么也得不到，尽管我可以看到有一个带有 json 的 XHR 响应，它具有:
location:{"name":"都柏林等"
请帮忙解开隐藏地点的谜团
编辑:5/23/2013- 在 Chrome 的开发人员工具中，我可以看到一条消息说(未捕获的类型错误:无法读取未定义的属性“名称” - 希望这有助于有人帮助我
当我查看 chrome 开发人员的控制台时，有关于上述未捕获类型错误的更多详细信息:Uncaught TypeError: Cannot read property 'name' of undefined linkedconnect.html:55

最佳答案
也许您可以临时用连接数组真正包含的日志替换代码设置 html:
//connHTML = connHTML + " <a href=\"" + connections[id].publicProfileUrl + "\">";
//connHTML = connHTML + connections[id].firstName + " " + connections[id].lastName + "</a>";
//connHTML = connHTML + " (Location: " + connections[id].location + ")</li>";
console.log(connections[id]);
当您记录一个对象时，您可以单击它来检查它的属性，也许某些项目根本不包含位置。在这种情况下，您可以尝试:
function setConnections(connections) {
var connHTML = "<ul>",
tmpLocation;
.....
tmpLocation= (connections[id].location && connections[id].location.name)
?connections[id].location.name:"Unknown";
connHTML = connHTML + " (Location: " + tmpLocation + ")</li>";
关于javascript - 尝试使用 javascript api 在 linkedin 中的第一个连接上提取位置信息，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/16693942/
