谷歌将API和URL缩写词API放在一起

Question

简介：我正在尝试使用google places API和URL shortener API创建一个web应用程序。如果用户搜索一个地方，它会提取地方id并创建一个长URL-"http://search.google.com/local/writereview?placeid="+place_id"，然后使用这个长URL使用Google URL缩短器API将其缩短，然后将其填充到文本字段中，以便用户可以复制生成的短URL。我不明白为什么它不会缩短URL。请注意，我的实际代码中有(api_key(。我真的很感激你的帮助。

谢谢。

问题是：您在5月30日之前访问过URL shortener服务吗。2018年？如果没有(这是我的情况(，我会收到一个403 Forbidden错误。所以这可能也是你的问题，正如这里所解释的。

在任何情况下，您可能都应该考虑使用FDL(Firebase Dynamic Links(迁移(或创建(您的代码。

该文档解释了如何使用FDL服务。一旦创建了项目，就可以参考这个和这个来正确构建查询。

最后，你应该能够通过Javascript做任何事情(不需要PHP(，你的代码应该是这样的(精简到最小代码(：

function initialize() {
var reviewUrl = 'http://search.google.com/local/writereview?placeid=';
var myLatLng = new google.maps.LatLng(46.2, 6.17);
var mapOptions = {
zoom: 4,
center: myLatLng,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map-canvas"), mapOptions);
var input = document.getElementById('pac-input');
var autocomplete = new google.maps.places.Autocomplete(input);
autocomplete.addListener('place_changed', function() {
var place = autocomplete.getPlace();
if (!place.geometry) {
return;
}
if (place.geometry.viewport) {
map.fitBounds(place.geometry.viewport);
} else {
map.setCenter(place.geometry.location);
map.setZoom(17);
}
getShortLink(reviewUrl + place.place_id);
});
}
function getShortLink(longUrl) {
var apiKey = 'MY_API_KEY'; // Replace this with the appropriate value
var params = {
"longDynamicLink": "https://example.page.link/?link=" + longUrl + "&apn=com.example.android&ibi=com.example.ios", // Replace this with the appropriate values
"suffix": {
"option": "SHORT"
}
}
$.ajax({
url: 'https://firebasedynamiclinks.googleapis.com/v1/shortLinks?key=' + apiKey,
type: 'POST',
data: jQuery.param(params),
contentType: "application/json",
success: function(response) {
alert(response.status);
},
error: function() {
alert("error");
}
});
}
initialize();

希望这能有所帮助！

Answer 2

由于谷歌停止了对URL缩短器的支持，另一种选择是使用Firebase动态链接(FDL(。我研究了FDL，发现它有点复杂，对我想要实现的目标来说付出了太多的努力。

我使用Bitly链接缩短器API来缩短我的URL，具有与谷歌URL缩短器相同的功能，并且更容易实现。

用这个来缩短我的URL:

function makeShort() {
//Bitly Shortner Function using AJAX    
$.ajax({
//Type of XML query request
type: 'GET',
url: 'https://api-ssl.bitly.com/v3/shorten?access_token='+"ACCESS-TOKEN"+'&longUrl='+longUrl,
dataType: 'json',
success: function(result) {
//If Http status Code is "OK" 
if(result.status_code === 200) {
//Store the result in shorted_url variable
$('#shorted_url').html('<a href="url"> url </a>'.replace (/url/g ,result.data.url ))
} else {
//Do nothing
} 
},
//Otherwise return the error 
error: function(jqXHR, textStatus, errorThrown) {
}
}); 
}

感谢您对此帖子的回复。

干杯。
