Javascript 使用json字符串向API发送请求时出错

javascript php json api curl

Javascript 使用json字符串向API发送请求时出错,javascript,php,json,api,curl,Javascript,Php,Json,Api,Curl,我有以下json字符串，我正试图将其发布到BetaFaceAPI。post是用PHP over cURL完成的，完成post的函数是： function bcall_endpoint($endpoint,$json_params){ //Init CURL $ch = curl_init($endpoint); curl_setopt($ch, CURLOPT_HEADER, false); curl_setopt($ch, CURLOPT_RETURNTRANSFER,

我有以下json字符串，我正试图将其发布到BetaFaceAPI。post是用PHP over cURL完成的，完成post的函数是：

function bcall_endpoint($endpoint,$json_params){
   //Init CURL
   $ch = curl_init($endpoint);
   curl_setopt($ch, CURLOPT_HEADER, false);
   curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1 );
   curl_setopt($ch, CURLOPT_POST,           1 );
   curl_setopt($ch, CURLOPT_VERBOSE, 0);
   curl_setopt($ch, CURLOPT_POSTFIELDS,     $json_params);
   curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
   $result = curl_exec($ch);
   return $result;
}

此外，pastebin文件中的json字符串由以下代码段生成：

$beta = array(
    'api_key'=>'d45fd466-51e2-4701-8da8-04351c872236',
    'api_secret'=>'171e8465-f548-401d-b63b-caf0dc28df5f',
    'imagefile_data'=>$base64,
    'detection_flags'=>'cropface,recognition,propoints,classifiers,extended'
);
$beta = json_encode($beta);

其中$base64是文件的base64字符串。base64字符串的创建如下所示：

$file = file_get_contents($_FILES['file']['tmp_name']);
$base64 = base64_encode($file);

API端点在这里，此版本的API与JSON一起工作。当我尝试将所有内容发送到端点时，应该会得到响应。与响应相比，在使用所有参数执行cURL post之后，我实际上得到了以下结果：

json字符串的大小有限制吗？

“/”只是“/”的转义序列，“\”不是有效的base64字符。尝试从base64编码的图像数据中删除所有“\”。

有点晚，但是，尝试添加内容长度标题

您应该隐藏api机密。这是一个公共机密：）这不是问题所在。但是谢谢你的意图，当我删除所有“\”字符后试图发送帖子时，我收到了500个内部服务器错误。我没有收到任何错误规范。API端点返回“500内部服务器错误”。
