having multiple ajax responses for one request

问题 I have some problems with ajax responses. Everything is working okay, however I got some strange behaviours. I am making an ajax-based chat. So, I use ajax requests-responses to make the stuff work. It is working fine, albeit since I started to use 2 polling functions sometimes the responses are retrieved multiple times. In specifics: I send 1 ajax package for message polling, and 1 ajax package for userlist polling. Both of them are sent periodically! Furthermore, they are sent with same

vue笔记之ajax请求及封装

常用的ajax库 vue-resource vue插件,非官方库,vue1.x 使用广泛 在线文档 下载: npm install vue-resource --save 理解: 使用 vue-resource插件后会给 vue的实例注册一个 $http 的属性 $http 是一个对象提供 get,post 等请求方法,这些请求方法是一个 promise 参考代码: // 引入模块 import VueResource from 'vue-resource' // 使用插件 Vue.use(VueResource) // 通过 vue/组件对象发送 ajax 请求 this.$http.get('/someUrl').then((response) => { // success callback console.log(response.data) //返回结果数据 }, (response) => { // error callback axios 通用的ajax请求库,官方推荐,vue2.x使用广泛 在线文档 安装: npm install axios --save 理解: axios 是一个模块,提供了一些属性和方法。 axios 模块提供如 get 、post 等方法,这些方法是一个promise对象 对于失败的响应可以通过功 error.response

nodeJS prevent timeout on res.download

纵然是瞬间 提交于 2020-01-23 08:07:26
问题 I have a POST call to my nodeJS server that searches for some data on the mongo database and returns a CSV file with the requested data. The problem is that the data search and processing exceeds the 2 minute nodeJS default timeout. On a diferent scenario y used: res.writeHeader(200,'application/json'); res.write('starting fetch .... '); to keep alive the request and prevent the timeout from the client by sending some res.write(''); from time to time. Now Im using res.download() to download

①创建一个服务类   @Injectable()   在服务类中定义方法、数据   sendRequest ( myUrl : string ) {     return this.http.get( myUrl ).map( (response : Response) => response.json() )   } ②给服务指定提供商   providers : [ MyHttpService ] 模块、组件限定作用范围 ③调用服务   import { }   this.myHttpService.sendRequset( ' 请求的地址 ' ).subscribe ( (result : any) => { console.log (reuslt)}) 来源: https://www.cnblogs.com/shanlu0000/p/12230051.html

什么是feign? 小说网站 https://m.198200.com 来自官网的解释:Feign makes writing java http clients easier 在使用feign之前,我们怎么发送请求? 拿okhttp举例: public static void post(String url, HashMap<String, String > paramsMap){ OkHttpClient mOkHttpClient = new OkHttpClient(); FormBody.Builder formBodyBuilder = new FormBody.Builder(); Set <String> keySet = paramsMap.keySet(); for (String key:keySet) { String value = paramsMap.get(key); formBodyBuilder.add(key,value); } FormBody formBody = formBodyBuilder.build(); Request request = new Request .Builder() .post(formBody) .url(url) .build(); try (Response response = mOkHttpClient
