我有一个JSON格式,我不能用Alamofire解码.
这是我的json:
"data":[
{
"id":37,
"status":"A\u00e7\u0131k",
"department":"Muhasebe",
"title":"Y\u00f6netim Panelinden Deneme 4 - Mail Kontrol",
"message":"<p>Y\u00f6netim Panelinden Deneme 4 - Mail Kontrol<br><\/p>",
"file":null,
"created_at":{
"date":"2018-01-13 01:59:49.000000",
"timezone_type":3,
"timezone":"UTC"
},
"replies":[
{
"id":6,
"ticket_id":37,
"admin_id":null,
"user_id":8593,
"message":"<p>test<\/p>",
"file":"uploads\/tickets\/8593-P87wd8\/GFV6H5M94y5Pt27YAxZxHNRcVyFjD554i80og3xk.png",
"created_at":"2018-01-18 11:16:55",
"updated_at":"2018-01-18 11:16:55"
}
]
},
这是我的JSON模型:
struct TeknikDestek : Decodable {
var id: Int?
var status: String?
var title: String?
var department: String?
var message: String?
var replies: [Replies]?
}
struct Replies: Decodable {
var replyid: Int?
var ticket_id: Int?
var admin_id: …如何使用phpspreadsheet库从数组创建Excel工作表列标题？
下面是我正在尝试的代码,但它不起作用:
// $header is an array containing column headers
$header = array("Customer Number", "Customer Name", "Address", "City", "State", "Zip");
$spreadsheet = new Spreadsheet();
$sheet = $spreadsheet->getActiveSheet();
$sheet->fromArray($header, NULL, 'A1');
// redirect output to client browser
header('Content-Type: application/vnd.ms-excel');
header('Content-Disposition: attachment;filename="myfile.xlsx"');
header('Cache-Control: max-age=0');
$writer = new Xlsx($spreadsheet);
$writer->save('php://output');
我正在尝试使用此命令行按高度裁剪图像：
convert 1053257.png -gravity South -crop 2910x3312+0+0 -background black +repage image-cropped-top.png
生成的图像未正确裁剪，因为运行命令后的尺寸为2791 x 3312。宽度也被裁剪了！
有人能帮忙吗？
以下代码使用Bootstrap版本3完全正常.但是,由于升级到Bootstrap 4 Beta2,淡入淡出过渡不起作用.它只是跳转到下一个图像而不是平滑过渡:

我想从c#app从Kusto DB中检索数据,任何人都可以帮助我.我有关于编写Kusto查询的知识,但我需要一些帮助来从Azure托管的Azure Kusto数据库中提取数据.
我尝试了以下代码,但它不起作用:

var reader = client.ExecuteQuery("MyTable | count");
// Read the first row from reader -- it's 0'th column is the count of records in MyTable
// Don't forget to dispose of reader when done.

.onWrite(event => {
const commentId = event.params.commentId;
const postId = event.params.postId;
// ref to the parent document
const docRef = admin.firestore().collection('posts').doc();
// get all comments and aggregate
return docRef.collection('comments').orderBy('createdAt', 'desc')
.get()
.then(querySnapshot => {
// get the total comment count
const commentCount = querySnapshot.size
const recentComments = []
// add data from the 5 most recent comments to the array
querySnapshot.forEach(doc => {
recentComments.push( doc.data() )
});
recentComments.splice(5)
// record last comment timestamp
const lastActivity = recentComments[0].createdAt
