Php 角度返回数据

我正在尝试创建一个服务，该服务将从PHPAPI返回json数据，但angular似乎不是返回纯json数据，而是返回json及其配置

services.js

.service('DistinctAPIService', function($http){
  var base = 'http://localhost/onseral/api/';
  this.listDistinct = function(table, field){
    return $http({
      method: 'POST',
      url: base + '/listDistinct.php',
      params: {
        table: table,
        field: field
      }
    });
  }
})

.controller('DistinctMatcode', function($scope, DistinctAPIService){
  DistinctAPIService.listDistinct('material', 'matcode').then(function(data){
    $scope.data = data;
    console.log(JSON.stringify(data));
  })
})

listdistinct.php

<?php
require_once '/config/dbconfig.php';

$table = $_GET['table'];
$field = $_GET['field'];

GetData($table,$field);

function GetData($tablename,$fieldname) {

    $sql = "SELECT DISTINCT $fieldname as expr1 FROM $tablename order by expr1 asc";
    try {
        $db = getdb();
        $stmt = $db->prepare($sql);
        $stmt->execute();
        $data = $stmt->fetchAll(PDO::FETCH_OBJ);
        $db = null;
        echo json_encode(array('data' => $data));
    } catch(PDOException $e) {
        echo '{"error":{"text":'. $e->getMessage() .'}}';
    }
 }
?>

有什么想法吗？

试试这个

   controller('DistinctMatcode', function($scope, DistinctAPIService){
     DistinctAPIService.listDistinct('material', 'matcode').then(function(response){
     $scope.data = response.data.data;
    console.log(JSON.stringify(data));
 })

在将数据发送到客户端之前，请使用header功能。 我修改了您的listdistinct.php文件。试试看，如果问题仍然存在，请告诉我

<?php $sql = "SELECT DISTINCT $fieldname as expr1 FROM $tablename order by expr1 asc";
try {
    $db = getdb();
    $stmt = $db->prepare($sql);
    $stmt->execute();
    $data = $stmt->fetchAll(PDO::FETCH_OBJ);
    $db = null;
    header('Content-Type: application/json');
    echo json_encode(array('data' => $data));
} catch(PDOException $e) {
    echo '{"error":{"text":'. $e->getMessage() .'}}';
}

它确实删除了
{“data”：
但仍然得到了另一个
{“data”：
，我只想得到结果为“[{”expr1:“value”}]试试这个$scope.data=data.data.data。我很高兴帮助你。更好地使用这个格式。我编辑它。仍然一样。实际上hadiJZ已经给出了答案，谢谢
<?php $sql = "SELECT DISTINCT $fieldname as expr1 FROM $tablename order by expr1 asc";
try {
    $db = getdb();
    $stmt = $db->prepare($sql);
    $stmt->execute();
    $data = $stmt->fetchAll(PDO::FETCH_OBJ);
    $db = null;
    header('Content-Type: application/json');
    echo json_encode(array('data' => $data));
} catch(PDOException $e) {
    echo '{"error":{"text":'. $e->getMessage() .'}}';
