PHP cURL JSON发送空白参数

Question

我正在尝试将JSON发送到java Web服务，但是从web服务获得响应所有null的响应，请参阅下文。我的代码有什么问题吗？

$buildApplication = array(
    'firsname'          => 'Keith',
    'surname'           => 'Francis',
    'companyName'       => 'Keiths Mobile Discos',
    'phone'             => '07123456789',
    'email'             => 'keith.francis@freedom-finance.co.uk',
    'sourceCode'        => 'W00T'
);
$data = json_encode($buildApplication);                                                                                                             
$ch = curl_init('http://10.50.1.71:8080/SME/api/details.json');                                                                      
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");                                                                     
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));                                                                 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);                                                                      
curl_setopt($ch, CURLOPT_HTTPHEADER, array(                                                                          
'Content-Type: application/json',                                                                                
'Content-Length: ' . strlen($data))                                                                       
);                                                                                                                
$result = curl_exec($ch);
var_dump($result);

Answer 1

• 您已发布firsname而非firstname。
• 您还使用了json_encode两次。

尝试如下：

$buildApplication = array(
    'firstname'          => 'Keith',
    'surname'           => 'Francis',
    'companyName'       => 'Keiths Mobile Discos',
    'phone'             => '07123456789',
    'email'             => 'keith.francis@freedom-finance.co.uk',
    'sourceCode'        => 'W00T'
);
$data = json_encode($buildApplication);                                                                                                             
$ch = curl_init('http://10.50.1.71:8080/SME/api/details.json');                                                                      
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");                                                                     
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);                                                                 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);                                                                      
curl_setopt($ch, CURLOPT_HTTPHEADER, array(                                                                          
'Content-Type: application/json',                                                                                
'Content-Length: ' . strlen($data))                                                                       
);                                                                                                                
$result = curl_exec($ch);
var_dump($result);

Answer 2

您已经使用了两次json_encode。

将以下行写为： -

curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
