PHP讀取API注意事項

有時候多是亂碼，倒不是由於json不是utf8格式，多是網頁編碼不對，須要在PHP下面添加：

header("Content-type:text/json;charset=utf-8");

下面是比較完備的PHP的curl代碼：

$host = "http://";
		$path = "/express/query";
		$method = "GET";
		$appcode = "";
		$headers = array();
		array_push($headers, "Authorization:APPCODE " . $appcode);
		$querys = "number=".$kd_number."&type=auto";
		$bodys = "";
		$url = $host . $path . "?" . $querys;

		$curl = curl_init();
		curl_setopt($curl, CURLOPT_CUSTOMREQUEST, $method);
		curl_setopt($curl, CURLOPT_URL, $url);
		curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);
		curl_setopt($curl, CURLOPT_FAILONERROR, false);
		curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
		curl_setopt($curl, CURLOPT_HEADER, false);
		if (1 == strpos("$".$host, "https://"))
		{
			curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
			curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
		}
		$data = curl_exec($curl);
		//print_r($data); die();
		curl_close($curl);
		$json_obj = json_decode($data);

注意若是不要返回頭部，要把HEADER設置成false，代碼中已經含有對是不是https的斷定。

用對象的格式讀取：

$json_obj->HeWeather5[0]->daily_forecast[0]->tmp->max

數組的選擇遍歷：

foreach ($json_obj->result->list as $list){ 
		if(1==$i){
			$i=0;
			continue;
		}
		
		$guocheng_list=$guocheng_list."時間：".$list->time."</br>"."狀態：".$list->status."</br>";
		}
