我在项目中使用Fetch(Fetch API),为了保持一致,我想创建一个接收所有参数(如方法,url和数据)的函数,并创建正确的请求,具体取决于如果是GET或POST请求。
是否有可能使用Fetch发送一个数据对象,该数据对象用于GET请求,将数据转换为参数字符串并且如果它是POST请求,它只是在正文中发送数据对象?
看起来像这样:
fetch ('/test', {
method: 'GET',
data: {
test: 'test'
}
});
这个疑问的灵感来自于这个jQuery ajax行为:
$.ajax({
url: '/test',
method: 'GET',
data: {
test: 'test'
}
});
这会产生这个请求:
'/test/?test=test'

If I pass the data object as normal in the fetch constructor for a GET request, would it send the request like the example I gave '/test/?test=test'
If you want to add query string to a fetch request :
var url = new URL("https://a.com/method"),
params = {a:1, b:2}
Object.keys(params).forEach(key => url.searchParams.append(key, params[key]))
fetch(url)
this will produce a request :

you could either use the Url class:
var url = new URL("/test/")
Object.keys({test: 'test', a: 1}).forEach(key => url.searchParams.append(key, params[key]))
fetch(url);
or parse the string yourself, if you want wider browser support:
var params = {test: 'test', a: 1},
qs = Object.keys(params).reduce(function(_qs, k, i){ return _qs + '&' + k + '=' + params[k]; }, '').substring(1);
console.log(qs)
