你也可以尝试在你的服务中设置标题，例如:

...
import { Injectable } from "@angular/core";
import { HttpClient, HttpHeaders, HttpParams } from "@angular/common/http";
...
 @Injectable()
export class MyService {

    private headers: HttpHeaders;


    constructor(private http: HttpClient..) 
    {


        this.headers = new HttpHeaders()
                    .append("Content-Type", "application/json")
                    .append("Accept", "application/json")
                    .append("LanguageCulture", this.headersLanguage)
                    .append("Cache-Control", "no-cache")
                    .append("Pragma", "no-cache")                   
    }
}
....

你可以添加一个唯一的querystring(我相信这就是jQuery对cache: false选项所做的)到请求。

$http({
    url: '...',
    params: { 'foobar': new Date().getTime() }
})

一个可能更好的解决方案是，如果您可以访问服务器，那么您可以确保设置必要的头文件以防止缓存。如果你使用ASP。这个答案可能会有帮助。

我没有对每个GET-request都禁用缓存，而是在$httpProvider中全局禁用它:

myModule.config(['$httpProvider', function($httpProvider) {
    //initialize get if not there
    if (!$httpProvider.defaults.headers.get) {
        $httpProvider.defaults.headers.get = {};    
    }    

    // Answer edited to include suggestions from comments
    // because previous version of code introduced browser-related errors

    //disable IE ajax request caching
    $httpProvider.defaults.headers.get['If-Modified-Since'] = 'Mon, 26 Jul 1997 05:00:00 GMT';
    // extra
    $httpProvider.defaults.headers.get['Cache-Control'] = 'no-cache';
    $httpProvider.defaults.headers.get['Pragma'] = 'no-cache';
}]);

正确的服务器端解决方案:在AngularJS中防止IE缓存的更好方法?

[OutputCache(NoStore = true, Duration = 0, VaryByParam = "None")]
public ActionResult Get()
{
    // return your response
}

我所做的保证是这样的:

myModule.config(['$httpProvider', function($httpProvider) {
    if (!$httpProvider.defaults.headers.common) {
        $httpProvider.defaults.headers.common = {};
    }
    $httpProvider.defaults.headers.common["Cache-Control"] = "no-cache";
    $httpProvider.defaults.headers.common.Pragma = "no-cache";
    $httpProvider.defaults.headers.common["If-Modified-Since"] = "Mon, 26 Jul 1997 05:00:00 GMT";
}]);

为了保证所有方法的正确使用，我不得不合并上述两个解决方案，但你可以用get或其他方法替换common，即put, post, delete，以使其适用于不同的情况。

你也可以尝试在你的服务中设置标题，例如:

    private headers: HttpHeaders;


    constructor(private http: HttpClient..) 
    {


        this.headers = new HttpHeaders()
                    .append("Content-Type", "application/json")
                    .append("Accept", "application/json")
                    .append("LanguageCulture", this.headersLanguage)
                    .append("Cache-Control", "no-cache")
                    .append("Pragma", "no-cache")                   
    }
}
