在Lat和Lon上使用Google Weather API-如何格式化? [英] Using Google Weather API with Lat and Lon - how to format?

问题描述

我想使用Google Weather API-通过传递lat和long值.我正在存储这些值，但是Google似乎需要以不同的格式显示这些值.

I want to use the Google Weather API - by passing lat and long values. I am storing these values, however it seems Google needs these values in different format.

即对于McTavish镇，我的值为45.5和-73.583

i.e. For the town of McTavish I have values of 45.5 and -73.583

这在这里有效: http: //api.wunderground.com/auto/wui/geo/WXCurrentObXML/index.xml?query=45.5,-73.583

但是当我将这些数据用于Google API时，它将无法正常工作:请参阅:www.google.com/ig/api?weather=,,,45.5,-73.583

But when I use these data for Google API, it does not work: See: www.google.com/ig/api?weather=,,,45.5,-73.583

任何帮助表示赞赏.我希望使用Google数据.

Any help appreciated. I would prefer to use the Google Data.

推荐答案

更新后的答案: 我刚刚注意到Google的Weather API还有其他一些违规之处.在任何情况下，如果适用，除负号外，您还需要有8位数字.请参阅以下代码块(基于Java)以获取正确的格式. (不是完美的算法，只是一个简单的示例，以便您可以看到结果)

UPDATED ANSWER: I have just noticed some OTHER irregularities with Google's Weather API. In ANY case, you need to have 8 numerical digits, in addition to the negative sign, if it applies. See the following code block (Java-based) for proper formatting. (Not the perfect algorithm, but just a quick example so that you can see the results)

lat = lat.replace(".", "");
while(lat.length() < 9)
    lat = lat.concat("0");
if(lat.contains("-"))
    lat = lat.substring(0, 9);
else
    lat = lat.substring(0, 8);

原始回应: 保罗，关于Google Weather API的窍门是，您不使用传统纬度/经度收到的坐标.相反，您解析出小数点.此外，Google Weather API的趣味性"似乎是要求数据以7到8位数字的字符串形式出现.因此，例如，45. 5应该确实是45.50000，而-73.583应该真的是-73.58300.这个7到8位数的长度似乎没有在任何负坐标前面包含负号(-).

ORIGINAL RESPONSE: Paul, the trick about Google's Weather API is that you don't use the coordinates as received by traditional latitude/longitude. Instead, you parse out the decimal points. Additionally, a "fun quirk" of Google's Weather API seems to be a requirement that the data come in as a 7- to 8-digit string. So, for instance, 45.5 should really be 45.50000, and -73.583 should really be -73.58300. This length of 7-8 digits does NOT seem to include the negative sign (-) in front of any negative coordinates.

因此，您的45.5(0000)变为4550000，而您的-73.583(00)变为-7358300.因此，最终的网址将是:

So, your 45.5(0000) becomes 4550000, and your -73.583(00) becomes -7358300. So the final URL would be:

http://www.google.com/ig/api?weather=,,,4550000,-7358300

请注意，再次使用7-8位数字表示4550000或45500000是可以接受的，-7358300或-73583000也是可以接受的.

Note that again, 7-8 digits means 4550000 or 45500000 would be acceptable, as would -7358300 or -73583000.

当我看到您的问题时，我才发现大约7到8位数字的长度-我试图将数据输入到我的天气分析程序中，并发现455,-73583无法产生正确的数据.

I only found out about the 7-8 digit length when I saw your question--I tried entering the data into my weather parsing program, and found that 455,-73583 does not yield proper data.

请注意，这是我的非正式实验，而不是官方文档，因此可能还会发现其他怪癖.

Note that this is by my unofficial experimentation, and not by official documentation, so there may be other quirks to be discovered.
