如何在php中创建cURL响应中对象的json
如何在php中创建cURL响应中对象的json
提问于 2020-03-19 13:38:42
我只是需要关于这个问题的帮助。以下是我想要在php输出中实现的内容，因为这是所需的结构。以JSON形式返回的事件对象数组。
[
{
"page_item_url":"2111",
"data":{
"startTime":"11:00"
"endTime":"12:00",
"summary":"<p>This has html tags in it from API<p>"
}
},{
"page_item_url":"2112",
"data":{
"startTime":"11:00"
"endTime":"12:00",
"summary":"<p>This has html tags in it from API<p>"
}
}
]返回的JSON应该是这样的，它是一个使用cUrl的API的调用。我有一个函数，它首先获取所有的ID，然后将其传递给一个变量；
function getOpportunityYearly(){
//curl here...
//I pushed all the ID in my array to the global scope
}现在，我有了我的ID数组：
$events = [2111,2112,2113,2114,2115];//etc
$jsonResponse = [];在其中，我想循环并从API调用另一个cUrl，然后应该通过$jsonResponse推送它。我的问题是，当我传递从getEventByID返回的响应并将其转换为json时，结构不正确。
for($i=0;$i<count($events);$i++){
getEventByID($events[$i]);
}
function getEventByID($eventID){
curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_URL =>'https://sampleapi.com/api/v3/data/opportunities/'.$eventID.'?key='.$GLOBALS['API_KEY'].'&fields=["startTime","endTime","physicalDifficulty","summary"]&where={"whereType":"AND","clauses":[{"fieldName":"displayToPublic","operator":"checked"}]}',
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 0,
CURLOPT_FOLLOWLOCATION => true,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "GET",
$response = json_decode(curl_exec($curl));
curl_close($curl);
$record = $response->records[0];
return json_encode([[
"page_item_url"=> $record->opportunities_id->value,
"data"=>[
"startTime"=>$record->startTime->displayValue,
"endTime"=>$record->endTime->displayValue,
"summary"=>$record->summary->displayValue,
]
]],JSON_HEX_QUOT | JSON_HEX_TAG);
}从getEventByID函数返回的应该是一个json格式，格式类似于上面的json示例。当我尝试将从getEventByID返回的代码用于单个对象时，可以查看https://prnt.sc/ris9g7，但是当我首先将响应推送到全局数组变量，然后对其进行编码时，得到的结果类似于以下https://prnt.sc/risjw5
我尝试创建一个数组并推送所有从getEventByID返回的内容，但输出不是JSON字符串，而是一个数组。我是不是做错了什么。
当我使用forloop时，页面速度很慢，并且获得了30秒的最大超时，我尝试使用$curl，CURLOPT_TIMEOUT_MS并将其设置为5分钟。但是，有没有其他方法可以让这个cURL不变慢呢？或者这是正常的，因为我们从API获取所有的ID events对象？你有什么建议可以改善这一点吗？
这是从getEventByID https://prnt.sc/ris8zx返回的类型这是我如何从curl响应https://prnt.sc/ris9c0构造和返回单个事件的方法这是正确的，我得到了https://prnt.sc/ris9g7如果我去掉json_encode中的括号，只传递一个键值的assoc数组，然后将它推入一个数组

编辑:最终使用multi解决了curl的多个请求。下面是事件中的每个Id的教程link将被处理，并将调用一个curl请求。并构造一个assoc数组。完成后，我已经将jsonResponse编码为JSON。
function multiCurl($eventArray){
// array of curl handles
$multiCurl = array();
// data to be returned
$result = array();
// multi handle
$mh = curl_multi_init();
foreach ($eventArray as $event) {
//$event are the ID per each event
// URL from which data will be fetched
// $curl = curl_init();
$multiCurl[$event] = curl_init();
curl_setopt_array($multiCurl[$event], array(
CURLOPT_URL =>'https://api.civicore.com/voc/api/v3/data/opportunities/'.$event.'?key='.$GLOBALS['API_KEY'].'&fields=["opportunityName","typeOfWork","firstDateInOpportunity","lastDateInOpportunity","startTime","endTime","physicalDifficulty","minimumAge","location","state","city","county","campingAvailable","groupsAllowed","registrationFormID","cRQ_payment","paymentAmount","additionalInformation","photo","displayToPublic","latitude","longitude","summary","description","photo"]&where={"whereType":"AND","clauses":[{"fieldName":"displayToPublic","operator":"checked"}]}',
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 0,
CURLOPT_FOLLOWLOCATION => true,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "GET"
));
curl_multi_add_handle($mh, $multiCurl[$event]);
}
do {
curl_multi_exec($mh,$index);
} while($index > 0);
// get content and remove handles
foreach($multiCurl as $key=>$value) {
$records = json_decode(curl_multi_getcontent($value));//response of each request
$record = $records->records[0];
if(strtolower($record->displayToPublic->displayValue) == 'yes'){
$eve = [
"page_item_url"=> $record->opportunities_id->value,
"data"=>[
"startTime"=>$record->startTime->displayValue,
"endTime"=>$record->endTime->displayValue,
"summary"=> $record->summary->displayValue
]
];
array_push($GLOBALS["jsonResponse"],$eve);
}
curl_multi_remove_handle($mh, $value);
}//foreach
curl_multi_close($mh);

在示例代码中确实有一些语法错误。不过，请试试这个。
<?php
function getEventByID($eventID)
{
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_URL => 'https://sampleapi.com/api/v3/data/opportunities/' . $eventID . '?key=' . $GLOBALS['API_KEY'] . '&fields=["startTime","endTime","physicalDifficulty","summary"]&where={"whereType":"AND","clauses":[{"fieldName":"displayToPublic","operator":"checked"}]}',
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 0,
CURLOPT_FOLLOWLOCATION => true,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "GET",
));
$response = json_decode(curl_exec($curl));
curl_close($curl);
$record = $response->records[0];
return json_decode(json_encode([
"page_item_url" => $record->opportunities_id->value,
"data" => [
"startTime" => $record->startTime->displayValue,
"endTime" => $record->endTime->displayValue,
"summary" => $record->summary->displayValue,
]
], JSON_HEX_QUOT | JSON_HEX_TAG));
}
$events = [2111, 2112, 2113, 2114, 2115]; //etc
$jsonResponse = [];
for ($i = 0; $i < count($events); $i++) {
$jsonResponse[] = getEventByID($events[$i]);
}
print_r($jsonResponse);
