用cURL使用imgur API获得空白响应

-1

这是我的代码 - 为什么我会得到空白的响应？用cURL使用imgur API获得空白响应

<?php 

$client_secret = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'; 
$client_id = 'xxxxxxxxxxxxxxx'; 

$file = file_get_contents("test-image.png"); 

$url = 'https://api.imgur.com/3/image.json'; 
$headers = array('Authorization: Client-ID $client_id'); 
$pvars = array('image' => base64_encode($file)); 

$curl = curl_init(); 

curl_setopt_array($curl, array(
    CURLOPT_URL=> $url, 
    CURLOPT_TIMEOUT => 30, 
    CURLOPT_POST => 1, 
    CURLOPT_RETURNTRANSFER => 1, 
    CURLOPT_HTTPHEADER => $headers, 
    CURLOPT_POSTFIELDS => $pvars 
)); 

$json_returned = curl_exec($curl); // blank response 
echo "Result: " . $json_returned ; 

curl_close ($curl); 

?>

编辑：

一些的var_dump结果：

var_dump(base64_encode($file)): 
    string iVBORw0KGgoAAAANSUhEUgAAAQAAAAEACAQAAAD2e2DtAADS7ElEQVR4Xu39B7SlaVbehz9fPDndnEPl0F2dw8z05CEjGIQAC2ELhABhIbAlZMmyhOEvB0mWg2zZQsaykJElkdMwwOTUM527qit0xVs353NPjl/6r/Vb77prCcYwDNM9A5pzV9UNJ33nffe7w7OfvbeV6A++xeZfwr+UM4hs85unP/m3r97+EAGIlcjip4SffSVK+LurPw23r97cP+z820YAJFsJXzY//8m+/TUnsEciWeeS9+oF/QPJ+qvJC3pS56wXk5+3Fm1XG/FsUnJ837LDKIhdO52Sx4GJO4OZ6L5txYtBEF7Udf1k/CdeA/zpv/0lu+THtu046SStiqZUiRK1kqS1Fu62c9NzltXYq3V7g6LizPhYuuSN24/GW14qmkliHaiehNbJeCGeSBwNrY6G1lF80719b/U3N2U/kXmxrVgak5KD+KsC8GXe6HXNas9KKSfpyC44l+yB'...

var_dump($json_returned): 
    boolean false

编辑2：

print_r(curl_getinfo($curl)): 
    '([url] => https://api.imgur.com/3/image.json [content_type] => [http_code] => 0 [header_size] => 0 [request_size] => 0 [filetime] => -1 [ssl_verify_result] => 0 [redirect_count] => 0 [total_time] => 0.296 [namelookup_time] => 0.047 [connect_time] => 0.312 [pretransfer_time] => 0 [size_upload] => 0 [size_download] => 0 [speed_download] => 0 [speed_upload] => 0 [download_content_length] => -1 [upload_content_length] => -1 [starttransfer_time] => 0 [redirect_time] => 0 [certinfo] => Array () [primary_ip] => 54.243.128.92 [primary_port] => 443 [local_ip] => 192.168.1.69 [local_port] => 4923 [redirect_url] =>)'

首先，你是否var_dump（$ file）;'看看你有没有在那里？ – 2013-04-09 08:21:36

我会做一些.. – rtheunissen 2013-04-09 08:22:21

尝试一个'print_r（curl_getinfo（$ curl））;'在关闭句柄之前，看看实际返回的是什么（如http代码），而不仅仅是“空白” – Uberfuzzy 2013-04-09 08:25:56

我已经解决了它：

'Authorization: Client-ID $client_id' should have been 
"Authorization: Client-ID $client_id"

基础知识，使用单引号我会来连接。

你需要设置这样一个完整的头：

$post_header = array("POST /3/image.json HTTP/1.1", 
"Host: api.imgur.com", 
"User-Agent: Mozilla/5.0 (Windows NT 5.1; rv:9.0.1) Gecko/20100101 Firefox/9.0.1", 
"Accept-Language: en-us,en;q=0.5", 
"Accept-Encoding: gzip, deflate", 
"Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7", 
"Connection: keep-alive", 
"Content-Type: application/x-www-form-urlencoded; charset=UTF-8", 
);

然后把这个标题的选择阵列CURLOPT_HTTPHEADER => $post_header

在这卷曲POST将如何工作。

。

另外，您需要使用http_build_query()来构建postdata以发送到CURLOPT_POSTFIELDS，而不是数组直接。
