使用OAuth 1发出Yahoo Weather API请求

Question

我遇到了Yahoo Weather API的问题,因为它没有给我任何数据.访问YDN网站后,我发现所有请求都应该从3月15日开始更新到OAuth 1(但我今天才开始工作!).它也被称为包括雅虎App密钥和秘密.当我必须使用我的app密钥和秘密时,请求网址现在应该是什么样子？

以前,我有这样的请求字符串: https://query.yahooapis.com/v1/public/yql?q=SOME_QUERY&format=json&env=store%3A%2F%2Fdatatables.org%2Falltableswithkeys&callback=

UPDATE

我最初问这个问题后13分钟,/ v1/public/endpoint的API调用再次正常工作.但是对我来说,回答我的问题仍然很有趣.

UPDATE

又下来了:(

Answer 1

如果你只是更换

http://weather.yahooapis.com/

同

http://xml.weather.yahoo.com/

它应该工作;)

Answer 2

目前的解决方案截至2016年4月中旬 - 由于开发者的愤怒,雅虎再次允许YQL请求而不再使用Oauth

您可以再次编写查询,而无需进行任何身份验证,如下所示:

https://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20weather.forecast%20where%20woeid%20in%20(select%20woeid%20from%20geo.places(1)%20where%20text%3D%22nome%2C%20ak%22)&format=json&env=store%3A%2F%2Fdatatables.org%2Falltableswithkeys

以下答案如果他们对任何人都有帮助.在雅虎改变的某些时期,他们确实有效.

以下是此答案的旧版本,可能仍然有效的历史原因

雅虎最新一轮更新后更新的答案 - 不安全的OAuth解决方法

您需要创建一个Yahoo帐户,然后在https://developer.yahoo.com/apps/create/创建一个Web应用程序.

然后,您需要使用OAuth库来正确编码您的客户端ID和客户端密钥.以下是一个基于JavaScript的示例,基于一个由Yahoo Donnelly撰写的Yahoo Example Page和一篇2008年博客文章.这将生成用于请求天气预报的编码URL.

//Fill in your consumer Key & Secret from Yahoo's App & adjust location as needed. 
//This Key & Secret combination is invalid & won't work for you
var consumerKey = "dj0yJmk9NkRjbXpjUEhPbjlnJmQ9WVdrOVFUQTFaV2wxTjJrbXnHbz3NQSktJnM9Y29uc3VtZXJzZWNyZXQmeD0wOQ--";
var consumerSecret = "9bea8a9k3934d16365ek7e23e0abo1bba4q5c03c";
var locationToQuery = "90210"; //Can be zip code or anything that works in the query select woeid from geo.places(1) where text=<Your Location>


var makeSignedRequest = function(ck,cs,loc) {

    var encodedurl = "https://query.yahooapis.com/v1/yql?q=select%20*%20from%20weather.forecast%20where%20woeid%20in%20(select%20woeid%20from%20geo.places(1)%20where%20text%3D%22"+loc+"%22)&format=json&env=store%3A%2F%2Fdatatables.org%2Falltableswithkeys";

    var accessor = { consumerSecret: cs, tokenSecret: ""};          
    var message = { action: encodedurl, method: "GET", parameters: [["oauth_version","1.0"],["oauth_consumer_key",ck]]};

    OAuth.setTimestampAndNonce(message);
    OAuth.SignatureMethod.sign(message, accessor);

    var parameterMap = OAuth.getParameterMap(message);
    var baseStr = OAuth.decodeForm(OAuth.SignatureMethod.getBaseString(message));           
    var theSig = "";

    if (parameterMap.parameters) {
        for (var item in parameterMap.parameters) {
            for (var subitem in parameterMap.parameters[item]) {
                if (parameterMap.parameters[item][subitem] == "oauth_signature") {
                    theSig = parameterMap.parameters[item][1];                    
                    break;                      
                }
            }
        }
    }

    var paramList = baseStr[2][0].split("&");
    paramList.push("oauth_signature="+ encodeURIComponent(theSig));
    paramList.sort(function(a,b) {
        if (a[0] < b[0]) return -1;
        if (a[0] > b[0]) return 1;
        if (a[1] < b[1]) return  -1;
        if (a[1] > b[1]) return 1;
        return 0;
    });

    var locString = "";
    for (var x in paramList) {
        locString += paramList[x] + "&";                
    }

    var finalStr = baseStr[1][0] + "?" + locString.slice(0,locString.length - 1);

    return finalStr;
};

//Use the encodedURL to make your request
var encodedURL = makeSignedRequest(consumerKey, consumerSecret, locationToQuery); 

应该注意的是,永远不要向公众展示您的消费者密钥或消费者秘密.您可以在此Plunkr中使用自己的Yahoo Credentials:http://plnkr.co/edit/EvLbgs

原始答案

不幸的是,到目前为止,服务器已经关闭以创建该应用程序.理想情况下,一旦他们备份,您可以使用服务器端代码来执行oauth部分.当发生这种情况时,我会尝试编辑这个答案.根据雅虎,除了没有/ public部分之外,URL将是相同的.最大的区别在于您需要使用验证帐户的网址发送请求标头.

在此之前,这是一个临时修复.你仍然可以使用带有邮政编码的YQL查询geo.places来获取woeid.

select * from geo.places where text=90210 limit 1

然后你可以从那里抓住你的woeid并在下面的url中使用它来获取xml feed:

http://weather.yahooapis.com/forecastrss?w=WOEID_GOES_HERE

我在这里创建了一个Plunker作为此临时修复的示例:http://plnkr.co/edit/dClPDtnToMhHqvKpfCzj？p = preview

以下是使用jQuery的要点:

var zipCode = 90210;

$.ajax({
    dataType: "json",
    headers:  { "Accept": "application/json; odata=verbose" },
    url: "https://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20geo.places%20where%20text%3D"+zipCode+"%20limit%201&format=json&env=store%3A%2F%2Fdatatables.org%2Falltableswithkeys",
    beforeSend: function(xhr){xhr.setRequestHeader('Accept', 'application/json; odata=verbose');},
    success: function(data){
        $.getJSON("https://query.yahooapis.com/v1/public/yql?callback=?", {
            q: "select * from xml where url=\"https://weather.yahooapis.com/forecastrss?w="+data.query.results.place.locality1.woeid+"\"",
            format: "json"
        },function (data) {
          var weather = data.query.results.rss.channel;
          var html = '<div><span class="temperature">'+weather.item.condition.temp+'<span class="degree">&deg;</span><sup>'+weather.units.temperature+'</sup></span><br><span class="wind-chill">Feels like: '+weather.wind.chill+'<span class="degree">&deg;</span></span></div></a>';
          $("#weather").html(html);
        });
    },
});
