What is the proper way to include special symbols such as "++" and "#" in a request?

I am facing an issue while trying to make a request to an ASP .NET CORE API from an Angular application using Typescript.

Upon sending the request, the API searches in an SQL database for any rows with the specified value.

The problem arises when attempting to send a request containing special characters like "C++" or "C#", as it only sends:

/FindBySyntax?Syntax=C

instead of /FindBySyntax?Syntax=C# or /File/FindBySyntax?Syntax=C++

For instance, if I try to send "Javascript", it works fine and returns rows where Syntax="Javascript".

I am seeking a solution to successfully send special characters like "++" and "#" in the request. Can anyone advise on how to achieve this?

selectSyntax(file: FileModel){
    this.service.formData = Object.assign({}, file);
    return this.http.get(this.service.BaseURL + '/File/FindBySyntax?Syntax=' + this.service.formData.Syntax)
    .toPromise()
            .then(res => this.service.list = res as FileModel[]);
}

Answer №1

To ensure that special characters are properly handled, you can use the Encode URI component

const encodedSyntax = encodeURIComponent(this.service.formData.Syntax);
return this.http.get(this.service.BaseURL + '/File/FindBySyntax?Syntax=' + encodedSyntax)

If needed, remember to decode the data on the server side using Decode URI component in the chosen programming language.

Answer №2

To ensure data security, the content held within this.service.formData.Syntax should undergo conversion using the JavaScript function encodeURIComponent().

For further information on the encodeURIComponent() function, visit the documentation available here. Additionally, for guidance on decoding within ASP .NET Core, you can refer to the following resource: here.
