Question

我需要使用JSON对象作为正文进行POST请求。这两种方法都给我HTTP 500服务器错误。我的代码有什么明显的错误吗？要温柔... 我尝试了几种方法，包括

$checkfor = ("'serverId':'Server','featureId':'Feature','propertyId':'Property'");
    $checkforJson = json_encode($checkfor);
    $uri = "http://localhost:8080/v1/properties";
    $response = \Httpful\Request::post($uri)
    ->method(Request::post)
    ->withoutStrictSsl()
    ->expectsJson()
    ->body($checkforJson)
    ->send();
    pre($response);

使用HTTPful资源。我已经尝试使用cURL

$service_url = "http://localhost:8080/v1/properties";

   // Initialize the cURL
   $ch = curl_init($service_url);

   // Set service authentication

   // Composing the HTTP headers     
   $body = array();
   $body[] = '"serverId" : "Server"';
   $body[] = '"featureId" : "Feature"';
   $body[] = '"propertyId" : "Property"';
   $body = json_encode($body);

   $headers = array();
   $headers[] = 'Accept: application/xml';
   $headers[] = 'Content-Type: application/xml; charset=UTF-8';

   // Set the cURL options
   curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
   curl_setopt($ch, CURLOPT_POSTFIELDS, $body);
   curl_setopt($ch, CURLOPT_POST, TRUE);
   curl_setopt($ch, CURLOPT_VERBOSE, 1);
   curl_setopt($ch, CURLOPT_HEADER, TRUE);
   curl_setopt($ch, CURLINFO_HEADER_OUT, true);
   curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);

   curl_setopt($ch, CURLOPT_TIMEOUT, 15);

   // Execute the cURL
   $data = curl_exec($ch);

   // Print the result
   pre($data);

Answer 1

您的json_encode需要一个数组。

它应该看起来像这样

<?php

$checkfor = ([
    'serverId'=>'Server',
    'featureId'=>'Feature',
    'propertyId'=>'Property'
]);

$checkforJson = json_encode($checkfor);
var_dump($checkforJson); // this will now work

为更好地理解，请阅读 doc

更新我也注意到curl脚本，您的数组需要再次修复

 $body['serverId'] = 'Server';

，然后不对发布字段进行json编码，它需要一个数组。

我前段时间有类似的问题。

对我有用的解决方案是：

$url = 'http://yourURL.com/api';
$data = array('field1' => 'value', 'field2' => 'value');
$options = array(
        'http' => array(
        'header'  => "Content-type: application/json\r\n",
        'method'  => 'POST',
        'content' => json_encode($data),
    )
);

$context  = stream_context_create($options);
$result = file_get_contents( $url, false, $context );
$response = json_decode( $result );

您尝试过吗：

Observable<R> obs = Observable.fromCallable(this::work);

也许是您设置阵列的方式

将JSON POST请求发送到PHP中的REST API
