从accuwweather api url获取数据

Question

我正在尝试从accuweither API获取json数据，用于PHP中的locationKey。输出为：file_get_contents(https://dataservice.accuweather.com/forecasts/v1/daily/1day/55488?apikey=0NSY9T1tFGo0NIXOYp23lro8DsuOcwPJ): failed to open stream: HTTP request failed!

<?php
$url = "https://dataservice.accuweather.com/forecasts/v1/daily/1day/55488?apikey=0NSY9T1tFGo0NIXOYp23lro8DsuOcwPJ";
$json = file_get_contents($url);
$data = json_decode($json,true);
print_r($data);
?>

CCD_ 2被启用。

我该怎么办？

编辑：我按如下方式更改了代码，但它不起作用

function weather(){
$url='http://dataservice.accuweather.com/forecasts/v1/daily/5day/55488?apikey=0NSY9T1tFGo0NIXOYp23lro8DsuOcwPJ';
$curl = curl_init();
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl,CURLOPT_FAILONERROR,true);
curl_setopt($curl, CURLOPT_URL, $url);
$result = curl_exec($curl);
$res=(object)array(
'response'  =>  curl_exec( $curl ),
'status'    =>  curl_getinfo( $curl, CURLINFO_RESPONSE_CODE ),
'info'      =>  (object)curl_getinfo( $curl ),
'errors'    =>  curl_error( $curl )
);
curl_close($curl);
echo 'response:'.$res->response;
echo '<br>';
echo 'status:'.$res->status;
echo '<br>';
echo 'errors:'.$res->errors;
}

结果是具有以下特征的空白页：

response:  
status:0  
errors:Empty reply from server

Fetchapi似乎是最简单的解决方案，因为端点确实存在Access-Control-Allow-Origin: *头-下面是一个简单的示例来说明基础知识。

const url='https://dataservice.accuweather.com/forecasts/v1/daily/1day/55488?apikey=0NSY9T1tFGo0NIXOYp23lro8DsuOcwPJ';

fetch( url )
.then( r=>r.json() )
.then( json=>{
const out=document.querySelector('output');

Object.keys( json ).forEach( k=>{
let div=document.createElement('div');
out.append( div );
let h1=document.createElement('h1');
h1.textContent=k;
div.append(h1);

// etc
});

json.DailyForecasts.forEach( obj=>{
console.info( obj )
})

})

<output></output>

在PHP中，您可以使用curl轻松地从AccuWeather API获取响应。下面的curl函数有一个cacert变量，它指向一个有效的cacert.pem文件——这在协商SSL连接时通常是需要的，如下所示。

<?php

function curl( $url=false ){
$cacert='c:/wwwroot/cacert.pem';

$curl=curl_init();
if( parse_url( $url, PHP_URL_SCHEME )=='https' ){
curl_setopt( $curl, CURLOPT_SSL_VERIFYPEER, true );
curl_setopt( $curl, CURLOPT_SSL_VERIFYHOST, 2 );
curl_setopt( $curl, CURLOPT_CAINFO, $cacert );
}
curl_setopt( $curl, CURLOPT_URL, trim( $url ) );
curl_setopt( $curl, CURLOPT_FOLLOWLOCATION, true );
curl_setopt( $curl, CURLOPT_FAILONERROR, true );
curl_setopt( $curl, CURLOPT_RETURNTRANSFER, true );
curl_setopt( $curl, CURLOPT_TIMEOUT, 60 );
curl_setopt( $curl, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 6.1; Win64; x64)' );
curl_setopt( $curl, CURLOPT_ENCODING, '' );
$res=(object)array(
'response'  =>  curl_exec( $curl ),
'status'    =>  curl_getinfo( $curl, CURLINFO_RESPONSE_CODE ),
'info'      =>  (object)curl_getinfo( $curl ),
'errors'    =>  curl_error( $curl )
);
curl_close( $curl );
return $res;
}


$url='https://dataservice.accuweather.com/forecasts/v1/daily/1day/55488?apikey=0NSY9T1tFGo0NIXOYp23lro8DsuOcwPJ';
$res=curl( $url );
if( $res->status==200 ){
printf('<pre>%s</pre>',print_r( json_decode( $res->response ),true ) );
}

?>

这就产生了：
