我只想从json链接获取id == 0
的数据我怎么能做到这一点!?
<?php
$claw = "https://euw.api.pvp.net/api/lol/euw/v1.3/stats/by-summoner/43216818/ranked?season=SEASON4&api_key=010ba2bc-2c40-4b98-873e-b1d148c9e379";
$z0r = file_get_contents($claw);
$gaza = json_decode($z0r, true);
foreach ($gaza['champions'] as $key => $value) {
if ($value['id'] == 0) {
$wins = $value['totalTripleKills'];
}
}
?>
我的代码没有显示任何内容..
任何人都可以帮忙!?

您没有输出任何内容,只是一次又一次地分配$wins
,也可能存在file_get_contents无法按预期使用https网址的问题。
使用cURL更快更容易,也是经过快速测试之后,
$value['totalTripleKills']
应为$value['stats']['totalTripleKills']
<?php
$url = "https://euw.api.pvp.net/api/lol/euw/v1.3/stats/by-summoner/43216818/ranked?season=SEASON4&api_key=010ba2bc-2c40-4b98-873e-b1d148c9e379";
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_HEADER, 0);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
$result = curl_exec($curl);
curl_close($curl);
if(empty($result)) {
echo 'Error fetching: '.htmlentities($url).' '.curl_error($curl);
}else{
$gaza = json_decode($result, true);
foreach ($gaza['champions'] as $key => $value) {
if ($value['id'] == 0) {
echo $value['stats']['totalTripleKills'].'<br>';
}
}
}
这也是一个相当大的响应,所以你需要考虑缓存一段时间的结果,但这超出了问题的范围。

您在stats数组中首先忘记输入错误,否则您无法获取totalTripleKills
值,然后输出。
$claw = "https://euw.api.pvp.net/api/lol/euw/v1.3/stats/by-summoner/43216818/ranked?season=SEASON4&api_key=010ba2bc-2c40-4b98-873e-b1d148c9e379";
$z0r = file_get_contents($claw);
$gaza = json_decode($z0r, true);
foreach ($gaza['champions'] as $key => $value) {
if ($value['id'] == 0) {
$wins = $value['stats']['totalTripleKills'];
}
}
echo $wins;
在解析json之前,一个有用的方法来理解数据的json结构是这个网站:http://jsonlint.com/。

你没有输出任何东西,
<?php
$claw = "https://euw.api.pvp.net/api/lol/euw/v1.3/stats/by-summoner/43216818/ranked?season=SEASON4&api_key=010ba2bc-2c40-4b98-873e-b1d148c9e379";
$z0r = file_get_contents($claw);
$gaza = json_decode($z0r, true);
foreach ($gaza['champions'] as $key => $value) {
if ($value['id'] == 0) {
$wins = $value['totalTripleKills'];
}
}
?>
试试这个
<?php
$claw = "https://euw.api.pvp.net/api/lol/euw/v1.3/stats/by-summoner/43216818/ranked?season=SEASON4&api_key=010ba2bc-2c40-4b98-873e-b1d148c9e379";
$z0r = file_get_contents($claw);
$gaza = json_decode($z0r, true);
echo "<pre>";
foreach ($gaza['champions'] as $key => $value) {
if ($value['id'] == 0) {
$wins = $value['totalTripleKills'];
var_export( $wins );
}
}
?>
