no-cors opaque request for html resource fetch blocked by CORB

由 a 夏天 提交于 2020-01-16 01:23:29
问题 I'm trying to fetch html file located at url https://sub.app.test/html from https://app.test using no-cors mode but the response is blocked by CORB (cross-origin read blocking). fetch('https://sub.app.test/html', { mode: 'no-cors'}) Why? 回答1: Even though no-cors mode is used (so the response doesn't need to have Access-Control-Allow-Origin to be allowed) the request is blocked by CORB because an html content is considered a data resource (it may contain sensitive data). Any resource that has

git常用命令总结

Git常用命令总结 git init 在本地新建一个repo,进入一个项目目录,执行git init,会初始化一个repo,并在当前文件夹下创建一个.git文件夹. git clone 获取一个url对应的远程Git repo, 创建一个local copy. 一般的格式是git clone [url]. clone下来的repo会以url最后一个斜线后面的名称命名,创建一个文件夹,如果想要指定特定的名称,可以git clone [url] newname指定. git status 查询repo的状态. git status -s: -s表示short, -s的输出标记会有两列,第一列是对staging区域而言,第二列是对working目录而言. git log show commit history of a branch. git log --oneline --number: 每条log只显示一行,显示number条. git log --oneline --graph:可以图形化地表示出分支合并历史. git log branchname可以显示特定分支的log. git log --oneline branch1 ^branch2,可以查看在分支1,却不在分支2中的提交.^表示排除这个分支(Window下可能要给^branch2加上引号). git log -

Fetching data in react

问题 I am new to react, so I am not sure how to call it. As a result, I apologize if this question was asked before. What I probably want to do is maping data, but I am not sure how to do it. componentDidMount() { fetch("https://reqres.in/api/users?page=3") .then(data => {return data.json()}) .then(datum => this.setState({client:datum.data})); } Above is my fetch component. The data that is taken from the API include the id, lastname, firstname. However, I want to assign id as slug instead and

SQL Server游标的使用【转】 Posted on 2011-11-26 00:33 moss_tan_jun 阅读( 206754) 评论( 53) 编辑 收藏 游标是邪恶的！ 在关系数据库中，我们对于查询的思考是面向集合的。而游标打破了这一规则，游标使得我们思考方式变为逐行进行.对于类C的开发人员来着，这样的思考方式会更加舒服。 正常面向集合的思维方式是: 而对于游标来说: 这也是为什么游标是邪恶的，它会使开发人员变懒，懒得去想用面向集合的查询方式实现某些功能. 同样的，在性能上，游标会吃更多的内存，减少可用的并发，占用宽带，锁定资源，当然还有更多的代码量…… 从游标对数据库的读取方式来说，不难看出游标为什么占用更多的资源，打个比方: 当你从ATM取钱的时候，是一次取1000效率更高呢，还是取10次100？ 既然游标这么“邪恶”，为什么还要学习游标 我个人认为存在既是合理.归结来说，学习游标原因我归纳为以下2点 1.现存系统有一些游标，我们查询必须通过游标来实现 2.作为一个备用方式，当我们穷尽了while循环,子查询，临时表，表变量,自建函数或其他方式扔来无法实现某些查询的时候，使用游标实现. T-SQL中游标的生命周期以及实现 在T-SQL中，游标的生命周期由5部分组成 1.定义一个游标 在T-SQL中，定义一个游标可以是非常简单，也可以相对复杂，取决于游标的参数

how to process fetch response from an 'opaque' type?

由 南笙酒味 提交于 2020-01-15 06:10:12
问题 I'm trying to correctly interpret the response from a fetch call to an URL, that I think is a json string. I've tried a many variations based on similar posts here, but nothing is getting me useful data to work with. Here is one attempt: fetch('http://serverURL/api/ready/', {method: "POST", mode: "no-cors"}) .then(function(response) { response.json().then(function(data) { console.log('data:' + data); }); }) .catch(function(err) { console.log('Fetch Error :-S', err); }); This returns a syntax

fetch().then() return content-type and body [duplicate]

问题 This question already has answers here : How do I access previous promise results in a .then() chain? (17 answers) Closed 2 years ago . Every fetch API example on the internet shows how to return only the body using response.json(), response.blob() etc. What I need is to call a function with both the content-type and the body as a blob and I cannot figure out how to do it. fetch("url to an image of unknown type") .then((response) => { return { contentType: response.headers.get("Content-Type")
