How to create HTTP GET request that queries a database (containing list of JSONs) and retrieves the appropriate JSON that satisfies the query?

由 自古美人都是妖i 提交于 2020-03-06 09:26:23
问题 I am working on an Angular project which involves submitting data (as a JSON) to the server using the HTTP POST/PUT request. The database is a list of JSONs which gets appended with a new, single JSON each time the POST/PUT request sends a new JSON to it. In each PUT/POST request, the JSON template looks like this: { "prop1": "123456", "prop2": "abc", "prop3": "xyz" } Let's call the above JSON to be of class Hero which has the same fields/properties. The list of JSONs in the database looks

问题 I'm trying to map through this API: https://api.nasa.gov/neo/rest/v1/neo/browse?api_key=DEMO_KEY and feed data into my state so I can make a google chart, but I'm stuck on how to do a certain part. At the moment I have this. state = { data: [ ['name', 'min estimated diameter', 'max estimated diameter'], ], } then when the page runs my CoponentDidMount() componentDidMount() { axios.get('https://api.nasa.gov/neo/rest/v1/neo/browse?api_key=DEMO_KEY',) .then((response) => { const restructuredData

问题 I'm trying to implement a simple GET request to send an Object of type SearchMessage from my Spring Boot server to my Angular client application. I run my server application and check if the relative JSON is correctly viewed on localhost:8080/greeting and it works.

MVVMCross Native Android Progressbar move element with the current progress

问题 I have a progressbar as shown in the following image. My problem is that I want to move the TextView that shows the current step of the progress, along with the progress. So in the step 3/7 it should move with the progress. The inside drawable is a styled xml shape drawable. rounded_corners_progress_bar <?xml version="1.0" encoding="utf-8"?> <layer-list xmlns:android="http://schemas.android.com/apk/res/android"> <item android:id="@android:id/background"> <shape> <corners android:radius="8dp"/

Web应用使用request对象

由 醉酒当歌 提交于 2020-02-29 14:25:40
request对象封装着一次用户请求，并且所有的请求参数都被封装在request对象中，客户端发送请求参数通常分为两种方式： GET方式的请求：直接在浏览器地址栏输入访问地址所发送的请求或提交表单发送请求时，该表单对应的form元素没有设置method属性，或设置method属性为get，这几种请求都是GET方式的请求。GET方式请求会将请求参数的名和值转换成字符串，并附加在原URL后，因此可以在地址栏中看到请求参数名和值。且GET请求传送的数据量较小，一般不能大于2KB。 POST方式的请求：这种方式通常使用提交表单的方式来发送，且需要设置form元素的method属性为post。POST方式传送的数据量较大，通常认为POST请求参数的大小不受限制，但往往取决于服务器的限制，POST请求传输的数据量总从GET传输的数据量大。而且POST方式发送的请求参数以及对应的值 放在HTML HEADER中传输，用户不能在地址栏中看到请求参数，安全性较高。 以页面request_form.jsp为例，参数传输方式为get，post方式只需要将method属性值改为post即可： <%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <!DOCTYPE html PUBLIC

How to pass boolean variable of false in a URL

由 北城以北 提交于 2020-02-27 04:28:08
问题 I cannot work out how to pass a variable with a boolean value of false through a URL string. What is the correct method? domain/page?test=false domain/page?test= domain/page?test=0 回答1: URLs are strings and all values in a URL are strings. When you see i=0 in a URL, 0 is a string. When you see b=true , true is a string. When you see s= , the value is an empty string. For those strings to take on another meaning—the integer 0 or the Boolean true , say—the server-side program must be told how

Golang Http Get Request very slow

由 送分小仙女□ 提交于 2020-02-24 17:32:06
问题 I have a very strange problem with a simple HTTP Get Request in Golang. Every request in Golang to https://www.alltron.ch/json/searchSuggestion?searchTerm=notebook needs about 6-8 seconds (!) If same request fired in Chrome, with Postman or with Powershell it needs less than a second. Does somebody has a clue why this happens? My Code: package main import ( "fmt" "io/ioutil" "log" "net/http" ) func main() { client := &http.Client{} req, _ := http.NewRequest("GET", "https://www.alltron.ch/json

Django Bounded forms in Class based views - CreateView class

由 六眼飞鱼酱① 提交于 2020-02-08 02:46:25
问题 How would I go about overriding the GET method in CreateView class based views to generate a bounded form , by which I mean it would have a preset value for some of its fields in the generated form (I need to instantiate the form with some defaults and not use the blank version of the form that CreateView uses by default). I tried looking at https://ccbv.co.uk/projects/Django/1.6/django.views.generic.edit/CreateView/ but dont quite understand the flow of the GET method in this class.
