400-Curl中的错误请求[关闭]

Question

当我尝试向 php 中的服务器发送请求时，我似乎遇到了问题。 http api 请求是这样的：

http://api.ean.com/ean-services/rs/hotel/v3/avail?minorRev14&apiKey=p9ycn9cxb2zp3k3gfvbf5aym&cid=55505&locale=en_US&hotelId=122212&stateProvinceCode=%20NV%C2%A4cyCode=USD&arrivalDate=12/27/2012&departureDate=12/28/2012&room1=2,&room2=2,18,15&room3=3,16,16,15&room4=3,&includeDetails=true&includeRoomImages=true

我的 php 代码中有以下部分，我认为错误正在发生：

$url = 'http://api.ean.com/ean-services/rs/hotel/v3/avail?minorRev14';
$url .= '&apiKey=p9ycn9cxb2zp3k3gfvbf5aym';
$url .= '&cid=55505';
$url .= '&locale=' . $locale . '&hotelId=' . $hotelid . '&stateProvinceCode=' . $state . '&currencyCode=USD';

$url .= '&arrivalDate=' . $datefr . '&departureDate=' . $dateto . '&' . $details . '&includeDetails=true&includeRoomImages=true';
$header = "Accept: application/json";

$ch = curl_init();
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
curl_setopt($ch, CURLOPT_ENCODING, "gzip");
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'GET');
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$retValue = curl_exec($ch);
$response = json_decode(curl_exec($ch));
$ee       = curl_getinfo($ch);
print_r($ee);

print_r($retValue);

这是我从 print_r(curl_getinfo($ch)) 语句中得到的：

Array (
    [url] => http://api.ean.com/ean-services/rs/hotel/v3/avail?minorRev14&apiKey=p9ycn9cxb2zp3k3gfvbf5aym&cid=55505&locale=en_US&hotelId=122212&stateProvinceCode= NV¤cyCode=USD&arrivalDate=12/27/2012&departureDate=12/28/2012&room1=2,&room2=2,18,15&room3=3,16,16,15&room4=3,&includeDetails=true&includeRoomImages=true
    [content_type] => text/html
    [http_code] => 400
    [header_size] => 181
    [request_size] => 340
    [filetime] => -1
    [ssl_verify_result] => 0
    [redirect_count] => 0
    [total_time] => 0.469
    [namelookup_time] => 0
    [connect_time] => 0.125
    [pretransfer_time] => 0.125
    [size_upload] => 0
    [size_download] => 349
    [speed_download] => 744
    [speed_upload] => 0
    [download_content_length] => 349
    [upload_content_length] => 0
    [starttransfer_time] => 0.469
    [redirect_time] => 0
    [certinfo] => Array ( )
    [redirect_url] =>
)

我不确定解决方案是什么，我一直在研究这个问题有一段时间了，希望有人可以帮助我，谢谢:)

Answer 1

添加

curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.0.3705; .NET CLR 1.1.4322)');

通过这种方式，它可以告诉它什么类型的代理（浏览器、蜘蛛等）正在请求内容。

所以最后，我将你的代码修改为

<?php 
$url ='http://api.ean.com/ean-services/rs/hotel/v3/avail?minorRev14&apiKey=p9ycn9cxb2zp3k3gfvbf5aym&cid=55505&locale=en_US&hotelId=122212&stateProvinceCode=%20NV%C2%A4cyCode=USD&arrivalDate=12/27/2012&departureDate=12/28/2012&room1=2,&room2=2,18,15&room3=3,16,16,15&room4=3,&includeDetails=true&includeRoomImages=true';

$header = array("Accept: application/json");

$ch = curl_init();
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
curl_setopt($ch, CURLOPT_ENCODING, "gzip");
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'GET');
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.0.3705; .NET CLR 1.1.4322)');

$retValue = curl_exec($ch);
$response = json_decode(curl_exec($ch));
$ee       = curl_getinfo($ch);
print_r($ee);

print_r($retValue);
?>

它对我来说很好用。你也可以检查一下吗？

有一些奇怪的地方：

&stateProvinceCode=%20NV%C2%A4cyCode=USD

                 ^^^^^^^^^^^^^^^^^^^

Converting it to plain ascii，它的“NV¤cyCode”

从我的观点来看应该是这样的

&stateProvinceCode=NV&cyCode=USD

作为信息，你从服务器得到什么样的错误？
