这是我自己的定制nuget包,我还没有发布并在本地测试.
nuget包由dll文件和nuspec文件组成,如下所示.
<?xml version="1.0"?>
<package >
<metadata>
<id>MyLib</id>
<version>1.0.0</version>
<authors>Author</authors>
<owners>Owner</owners>
<licenseUrl>license url</licenseUrl>
<projectUrl>project url</projectUrl>

<files>
<file src="bin\Debug\netstandard1.4\*.dll" target="lib" />
<file src="bin\Debug\netstandard1.4\*.pdb" target="lib" />
</files>
</package>
我已将nupkg文件复制到某个位置并将其添加到
Visual studio Tools -> Options -> Packages -> sources directory
错误:
Package MyLib 1.0.0 is not compatible with netcoreapp1.0 (.NETCoreApp,Version=v1.0). Package MyLib 1.0.0 supports: net (.NETFramework,Version=v0.0)
Package restore failed. Rolling back package changes for 'WebApplication1'.
不确定如何解决问题或查找更多信息.

dll文件是使用模板(.Net Framework 4.5.2)创建的
Templates -> Visual C# -> .NET …编辑
代码为#1.继续重试,直到诺言解决(语言的任何改进社区等？)
Promise.retry = function(fn, times, delay) {
return new Promise(function(resolve, reject){
var error;
var attempt = function() {
if (times == 0) {
reject(error);
} else {
fn().then(resolve)
.catch(function(e){
times--;
error = e;
setTimeout(function(){attempt()}, delay);
});
}
};
attempt();
});
};
使用
work.getStatus()
.then(function(result){ //retry, some glitch in the system
return Promise.retry(work.unpublish.bind(work, result), 10, 2000);
})
.then(function(){console.log('done')})
.catch(console.error);
#2的代码继续重试,直到条件then以可重用的方式满足结果(条件是变化的).
work.publish()
.then(function(result){
return new Promise(function(resolve, reject){
var intervalId = setInterval(function(){
work.requestStatus(result).then(function(result2){
switch(result2.status) { …我的iPad上安装了带有iOS 8.3的Safari 8.0.6,在我的Mac上通过Web Inspector进行调试(10.10.3)时,连接断开连接(断开时我看不到开发菜单下的设备名称)但是可以恢复如果我退出safari然后重新启动然后我能够再次远程刷新和检查.
我已经看过很多关于此的文章,但它们似乎已经过时了,例如Google Docs电子表格网址都没有关键参数.我也读过这篇文章: 来自谷歌电子表格的JSON数据
然后我阅读此内容以访问数据 https://developers.google.com/gdata/samples/spreadsheet_sample
我的电子表格位于:https: //docs.google.com/spreadsheets/d/1SKI5773_68HiSve1fsz7fr4gotjFWHB7KBuVsOlLz6I/edit#gid=0
我试过使用这段代码,我觉得我的密钥或语法有问题,请指导修复.

我已嵌套数组,我能够检索第二级数组的promise,但不知道如何实现then一次顶级结束.
result.forEach(function(entity){ // outer list ???
return Promise.all(entity.urls.map(function(item){
return requestURL(item.href);
}));
});
例如,如果results有两个或两个以上项目,每个item有10个或多个URL抓取,我们将如何实现then的[Promise.all][1]所有承诺.原生解决方案请.
基本上以正确的方式处理嵌套的promises数组.
数据结构:
var result = [
{
urls: [
{href: "link1"},
{href: "link2"},
{href: "link3"}
]
},
{
urls: [
{href: "link4"},
{href: "link5"},
{href: "link6"}
]
}
];
我正在尝试将存储在 interface[] 中的数据恢复为字符串数组。遇到意外错误。
type Foo struct {
Data interface{}
}
func (foo Foo) GetData() interface{} {
return foo.Data
}
func (foo *Foo) SetData(data interface{}) {
foo.Data = data
}
func main() {
f := &Foo{}
f.SetData( []string{"a", "b", "c"} )
var data []string = ([]string) f.GetData()
fmt.Println(data)
}
错误：main.go:23：语法错误：语句结束时出现意外的 f
是否有类似于角度的东西可以转换这种在group_header下分组的json数据.
外部列表按组排序数据,然后是该组的内部列表数据项,如果可以对这些数据进行分组,我无法理解这一点？
var data = [
{
"id":23,
"name":"Fun Run (Pre-Registration Required)",
"date":"Wednesday Nov 12",
"group_header":"Sessions from 7:00 am to 1:45 pm"
},
{
"id":24,
"name":"Breakfast",
"date":"Wednesday Nov 12",
"group_header":"Sessions from 7:00 am to 1:45 pm"
},
{
"id":25,
"name":"Opening Address",
"date":"Wednesday Nov 12",
"group_header":"Sessions from 7:00 am to 1:45 pm"
},
{
"id":25,
"name":"abc",
"date":"Wednesday Nov 12",
"group_header":"Sessions from 1:00 pm to 9:00 pm"
},
{
"id":26,
"name":"xyz",
"date":"Wednesday Nov 12",
"group_header":"Sessions from 1:00 pm to 9:00 pm"
}, …我有两个错误,
一个.不可能的类型断言.我们可以从接口类型转换为实际的类型对象
湾 不确定评估的含义是什么,但未使用
type IAnimal interface {
Speak()
}
type Cat struct{}
func (c *Cat) Speak() {
fmt.Println("meow")
}
type IZoo interface {
GetAnimal() IAnimal
}
type Zoo struct {
animals []IAnimal
}
func (z *Zoo) GetAnimal() IAnimal {
return z.animals[0]
}
测试
var zoo Zoo = Zoo{}
// add a cat
var cat IAnimal = &Cat{}
append(zoo.animals, cat) // error 1: append(zoo.animals, cat) evaluated but not used
// get the cat
var same_cat Cat = zoo.GetAnimal().(Cat) // error …它是一个仅限框架项目(SWIFT),它构建一个库(.framework模块),与项目链接以及单元测试,最终会出现以下错误.
