我在python中遇到了JSON的问题.
事实上,如果我尝试执行此代码,python会给我一个排序的JSON字符串!
例如:
values = {'profile' : 'testprofile',
'format': 'RSA_RC4_Sealed',
'enc_key' : base64.b64encode(chiave_da_inviare),
'request' : base64.b64encode(data)
}
values_json = json.dumps(values, sort_keys=False, separators=(',', ':'))
这是输出:
{"profile":"testprofile","enc_key":"GBWo[...]NV6w==","request":"TFl[...]uYw==","format":"RSA_RC4_Sealed"}
如你所见,我试图使用"sort_keys = False",但没有任何改变.
如何阻止Python对JSON字符串进行排序？
我有一个现有的Meteor + React应用程序,可以与远程MongoDB一起使用.如果我使用以下.sh文件运行它,此应用程序将连接到远程数据库:
DB_URL="mongodb://..."
MONGO_URL=$DB_URL \
meteor run --settings config/settings.json
但是如果我尝试运行Cordova应用程序,它总是连接到本地MongoDB并忽略任何配置.我这样试试:
DB_URL="mongodb://..."
MONGO_URL=$DB_URL \
meteor run ios-device --verbose --settings config/settings.json
我怎样才能正确设置Cordova应用程序的MongoDB网址？
为了连接服务器,我发现使用PHP,我需要使用openssl_seal().没关系,但我想使用Python.我无法转换openssl_seal()为等效函数.
你能帮助我吗？
这是做什么的openssl_seal():
描述int openssl_seal(string $ data,string&$ sealed_data,array&$ env_keys,array $ pub_key_ids)
Run Code Online (Sandbox Code Playgroud)openssl_seal() seals (encrypts) data by using RC4 with a randomly generated secret key. The key is encrypted with each of the public keys associated with the identifiers in pub_key_ids and each encrypted key is returned in env_keys. This means that one can send sealed data to multiple recipients (provided one has obtained their public keys). Each recipient must receive both the sealed data …
我的应用程序需要使用PyCurl,所以我尝试在我的Mac上安装它,但我发现了很多问题和错误.
要求:首先,我必须说我的Mac上运行的Python版本是基于32位的,因为我需要使用需要32位Python的WxPython.为此,我使用了:
defaults write com.apple.versioner.python Prefer-32-Bit -bool yes
要安装我使用过的PyCurl:
sudo env ARCHFLAGS="-arch x86_64" easy_install setuptools pycurl
终端返回:

也许我的问题很愚蠢,但我无法弄清楚
谢谢
编辑:添加了代码
function scriviNumeroTastiera(tasto){
console.time('Funzione ScriviNumeroTastiera');
contenutoInput = document.getElementById('artInserito').value;
if ($('#cursoreImg').css('display') == 'none'){
//$('#cursoreImg').show();
}
else if (tasto == 'cancella'){
//alert(contenutoInput.length);
if (contenutoInput.length == 0) {
}
else {
indicePerTaglioStringa = (contenutoInput.length)-1;
contenutoInput = contenutoInput.substr(0, indicePerTaglioStringa);
$('#artInserito').val(contenutoInput);
//alert('tastoCanc');
margineAttualeImg = $('#cursoreImg').css('margin-left');
indicePerTaglioStringa = margineAttualeImg.indexOf('p');
margineAttualeImg = margineAttualeImg.substr(0, indicePerTaglioStringa);
margineAggiornato = parseInt(margineAttualeImg)-20;
$('#cursoreImg').css('margin-left', margineAggiornato+'px');
}
}
else {
//contenutoInput = document.getElementById('artInserito').value;
contenutoAggiornato = contenutoInput+tasto;
margineAttualeImg = $('#cursoreImg').css('margin-left');
indicePerTaglioStringa = margineAttualeImg.indexOf('p');
margineAttualeImg = margineAttualeImg.substr(0, indicePerTaglioStringa);
margineAggiornato …你能帮我理解为什么这不起作用吗？
var elementTab1 = $('#tab1 .item-media.modificato');
elementTab1[0].addClass('selezionato');
这是通过这个错误
TypeError:undefined不是函数(评估'elementTab1 [0] .addClass('selezionato')')
谢谢
