Angular url plus sign converting to space

Question

I have angular application where i want to pass plus sign + in query string like:

http://localhost:3000/page?name=xyz+manwal

Answer 1

In Angular 5.2.7+ the "+" is replaced with space " " in a query string.

Here is the corresponding commit : fix(router): fix URL serialization

If you want to change this behaviour and replace the "+" with "%2B" you can create a custom url serializer and provide it in the AppModule providers.

import { DefaultUrlSerializer, UrlSerializer, UrlTree } from '@angular/router';

export default class CustomUrlSerializer implements UrlSerializer {
    private _defaultUrlSerializer: DefaultUrlSerializer = new DefaultUrlSerializer();

    parse(url: string): UrlTree {
        // Encode "+" to "%2B"
        url = url.replace(/\+/gi, '%2B');
        // Use the default serializer.
        return this._defaultUrlSerializer.parse(url);
    }

    serialize(tree: UrlTree): string {
        return this._defaultUrlSerializer.serialize(tree).replace(/\+/gi, '%2B');
    }
}

@NgModule({
    imports: [
        BrowserModule,
        BrowserAnimationsModule,
        AppRoutingModule
    ],
    declarations: [
        AppComponent
    ],
    providers: [
        { provide: UrlSerializer, useClass: CustomUrlSerializer }
    ],

    entryComponents: [],
    bootstrap: [AppComponent]
})
export class AppModule {
}

http://localhost:3000/page?name=xyz+manwal

The URL will be converted to:

http://localhost:3000/page?name=xyz%2Bmanwal

Hope this will help.
