从Javascript到PHP获取JSON

我有一个javascript函数，可以将JSON发送到我的服务器：

$("#sendRoute").live('click', function(){            
  trackCoords_str = JSON.stringify(trackCoords);             
  final_time_m_str = JSON.stringify(final_time_m);                
  final_time_s_rounded_str = JSON.stringify(final_time_s_rounded);
  aver_speed_km_h_rounded_str = JSON.stringify(aver_speed_km_h_rounded);
  total_km_rounded_str = JSON.stringify(total_km_rounded);
  $.ajax({
  url: "http://test.whirlware.biz/server/",               
  type: "POST",
  data: { 
    route : trackCoords_str,                 
    timeInMinutes: final_time_m_str,               
    timeInSeconds: final_time_s_rounded_str,
    averageSpeed: aver_speed_km_h_rounded_str,
    distance: total_km_rounded_str,
  },
  dataType: "json"
 });
});

混合使用PHP和JS代码来接收和显示我的JSON数据

$("#sendRoute").live('click', function(){            
  trackCoords_str = JSON.stringify(trackCoords);             
  final_time_m_str = JSON.stringify(final_time_m);                
  final_time_s_rounded_str = JSON.stringify(final_time_s_rounded);
  aver_speed_km_h_rounded_str = JSON.stringify(aver_speed_km_h_rounded);
  total_km_rounded_str = JSON.stringify(total_km_rounded);
  $.ajax({
  url: "http://test.whirlware.biz/server/",               
  type: "POST",
  data: { 
    route : trackCoords_str,                 
    timeInMinutes: final_time_m_str,               
    timeInSeconds: final_time_s_rounded_str,
    averageSpeed: aver_speed_km_h_rounded_str,
    distance: total_km_rounded_str,
  },
  dataType: "json"
 });
});

<?php
$route = $_POST['route'];
$timeInMinutes=$_POST['timeInMinutes'];
$timeInSeconds=$_POST['timeInSeconds'];
$averageSpeed=$_POST['averageSpeed'];
$distance=$_POST['distance'];

$trackCoords = json_decode($route, false);
$total_km_rounded = json_decode($timeInMinutes, false);
$final_time_m = json_decode($timeInSeconds, false);
$final_time_s_rounded = json_decode($averageSpeed, false);
$aver_speed_km_h_rounded = json_decode($distance, false);

echo $trackCoords['coordsarray'];
echo $total_km_rounded;
echo $final_time_m;
echo $final_time_s_rounded;
echo $aver_speed_km_h_rounded;
?>

<script type="text/javascript">
var total_km_rounded = '<?php echo $total_km_rounded ?>';
document.write('Растояние: ' + total_km_rounded);
var final_time_m = '<?php echo $final_time_m ?>';
document.write('Растояние: ' + final_time_m);
var final_time_s_rounded = '<?php echo $final_time_s_rounded ?>';
document.write('Растояние: ' + final_time_s_rounded);
var aver_speed_km_h_rounded = '<?php echo $aver_speed_km_h_rounded ?>';
document.write('Растояние: ' + aver_speed_km_h_rounded);
</script>

var总公里数四舍五入=“”；
文件。填写（‘аааааааааааааа1072；
var final_time_m=''；
文件。书写（‘аааааааааааааа1072；
var最终时间四舍五入=“”；
文件。书写（‘ааааааааааааааа；
var Averar_speed_km_h_rounded=''；
文件。书写（‘аааааааааааааааа；

但是当我发送JSON数据时，我的服务器不会显示它。我在哪里犯了错误？也许我可以用另一种方式接收JSON？

试试这个，

success:function（response）{alert（'success！'）；}，

在

数据之后，而不是
数据内部

$("#sendRoute").live('click', function(){            
  trackCoords_str = JSON.stringify(trackCoords);             
  final_time_m_str = JSON.stringify(final_time_m);                
  final_time_s_rounded_str = JSON.stringify(final_time_s_rounded);
  aver_speed_km_h_rounded_str = JSON.stringify(aver_speed_km_h_rounded);
  total_km_rounded_str = JSON.stringify(total_km_rounded);
  $.ajax({
  url: "http://test.whirlware.biz/server/",               
  type: "POST",
  data: { 
    route : trackCoords_str,                 
    timeInMinutes: final_time_m_str,               
    timeInSeconds: final_time_s_rounded_str,
    averageSpeed: aver_speed_km_h_rounded_str,
    distance: total_km_rounded_str,
  },
  dataType: "json"
 });
});

data: { 
 route : trackCoords_str,                 
timeInMinutes: final_time_m_str,               
timeInSeconds: final_time_s_rounded_str,
averageSpeed: aver_speed_km_h_rounded_str,
distance: total_km_rounded_str   
},
success: function(response) {alert('Success!');},

您应该像这样对数组进行JSON.stringify（）：

$("#sendRoute").live('click', function(){            
  trackCoords_str = JSON.stringify(trackCoords);             
  final_time_m_str = JSON.stringify(final_time_m);                
  final_time_s_rounded_str = JSON.stringify(final_time_s_rounded);
  aver_speed_km_h_rounded_str = JSON.stringify(aver_speed_km_h_rounded);
  total_km_rounded_str = JSON.stringify(total_km_rounded);
  $.ajax({
  url: "http://test.whirlware.biz/server/",               
  type: "POST",
  data: { 
    route : trackCoords_str,                 
    timeInMinutes: final_time_m_str,               
    timeInSeconds: final_time_s_rounded_str,
    averageSpeed: aver_speed_km_h_rounded_str,
    distance: total_km_rounded_str,
  },
  dataType: "json"
 });
});

首先，成功的作用。查看文档。位置错误。我知道，谢谢，mybe你知道另一个可能导致问题的原因吗？我删除了成功：函数（响应）{alert（'success！'）；}，这不是问题的原因我没有说，这是答案，这也是问题的原因。！我试过了，但没用，我也改变了index.php中的变量，但没有结果。你能用success（）函数将从php发布的数据回显到这个javascript吗？我添加了success:function（）{alert（'success！'）；}，error:function（）{alert（'error！'；}，当我发送JSON时，它显示“error”，所以我的JSON不会被发送。原因可能是什么？请在成功后查看此错误：：错误：函数（xhr，ajaxOptions，thrownError）{alert（xhr.responseText）；alert（thrownError）；}我有两个错误：但我不知道这里有什么语法错误，我只发送数字数据
