Question

我正在尝试创建一个服务，它将从php api返回一个json数据，但不是返回纯json数据，而是似乎将JSON与其配置一起返回。

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() .'}}';
    }
 }
?>

而不是返回正确的JSON数据，它返回

{"data":{"data":[{"expr1":"CFFBPS16"}]},"status":200,"config":{"method":"POST","transformRequest":[null],"transformResponse":[null],"url":"http://localhost/onseral/api//listDistinct.php","params":{"table":"material_copy","field":"matcode"},"headers":{"Accept":"application/json, text/plain, */*"}},"statusText":"OK"}

任何想法？

Answer 1

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));
 })

Answer 2

在向客户端发送数据之前使用标头功能。我修改了 listdistinct.php 文件。尝试一下，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() .'}}';
}

} ？＆GT;
