上述问题仅在某些时候出现。我不知道为什么,但是我假设我的用于在JSON文件中保存和加载JSON对象的php脚本没有完美完成。
writeLanguage.php
<?php
$myFile = "languages.json";
$cmsData = $_POST['data'];
$obj = json_decode($cmsData, true);
$myFile = "language.json";
$fh = fopen($myFile, 'w') or die("can't open file");
fwrite($fh,json_encode($obj));
fclose($fh);
readLanguage.php
$cmsData = $_GET['data'];
$myFile = "language.json";
$fhh = fopen($myFile, 'r') or die("can't open file");
$jsondata = file_get_contents($myFile);
fclose($fhh);
$json = json_decode($jsondata, true);
echo $jsondata;
这是我的JavaScript代码:
DataService.prototype.loadLanguagePromise = function () {
return new Promise(function (resolve, reject) {
$.ajax({
url: "php/services/readLanguage.php",
type: "GET",
async: true,
dataTyp: 'json',
success: function (data) {
resolve("stuff worked");
},
error: function (xhr, desc, err) {
reject(Error("It broke"));
}
})
})
};
DataService.prototype.saveLanguage = function (cmsObject) {
return new Promise(function (resolve, reject) {
$.ajax({
url: "php/services/writeLanguage.php",
type: "POST",
data: {data: JSON.stringify(cmsObject)},
dataTyp: 'json',
success: function (data) {
resolve(data);
},
error: function (xhr, desc, err) {
reject(xhr, desc, err);
}
})
})
};
我一直在寻找分段错误的定义,但无法真正得到“ aaaaah ...当然,这就是原因”。
答案 0 :(得分:0)
尝试删除fopen,fwrite和fclose。在第一种情况下,您仅需要file_put_contents(),在第二种情况中-仅需file_get_contents。
<?php
$myFile = "languages.json";
$cmsData = $_POST['data'];
$obj = json_decode($cmsData, true);
$fh = file_put_contants($myFile, $cmsData,LOCK_EX) or die("can't open file");
$cmsData = $_GET['data'];
$myFile = "language.json";
$jsondata = file_get_contents($myFile);
$json = json_decode($jsondata, true);
echo $jsondata;
