Today, I spent several hours figuring out the weather interface in Baidu API. To be honest, Baidu is also a pitfall. I tried it for the first time because I chose a server as the application type, why can't I verify it? I chose the sn verification white list.

The second time I tried it directly in the browser, the result was successfully read into the json data, and the rest will be parsed ....

Run the Code directly.

Weather
 $ Ak, "location" => $ location, "output" => $ output );

// Baidu sn algorithm $ sn = caculateAKSN ($ ak, $ sk, $ url, $ querystring_arrays); return sprintf ($ url, $ ak, $ location, $ output, $ sn);} function browser ($ output, $ location) {// browser test ----- $ ak = "xxxxxxxx"; $ url = "http://api.map.baidu.com/telematics/v3/weather? Ak = % s & location = % s & output = % s "; return sprintf ($ url, $ ak, $ location, $ output);} // $ template = http://api.map.baidu.com/telematics/v3/weather? Location = % s & output = % s & ak = % s $ weather_contents = file_get_contents ($ result); print_r (json_decode ($ weather_contents);?>

From another submitted city, the operations after I come in are like the above. Here I will explain a few places where ak is the app key in the Baidu application. If it is a server type, secret key, if the browser type does not exist, use the sn algorithm provided by Baidu for encryption. The Code is as follows:

 Value format. The signature cannot be re-ordered after calculation, or the data element * @ param string $ method can only be 'post' or 'get' */function caculateAKSN ($ ak, $ sk, $ url, $ querystring_arrays, $ method = 'get') {if ($ method = 'post') {ksort ($ querystring_arrays );} $ querystring = http_build_query ($ querystring_arrays); return md5 (urlencode ($ url. '? '. $ Querystring. $ sk) ;}?>

I haven't understood it for a long time. The url has no format. What do I mean? I did it later, because I read it... why are there two different pages ....

Forgive me for my IQ.

Location can be transcoded using urlencode to avoid errors. In the end, get the complete result and use file_get_contents to get the data, which is output in array format...

For beginners, I want to help you.
