Uri QueryString Composer

Have you ever needed to make an http call and had to assemble a giant query string entirely manually?

I hope you never have to. 😆

What is it?

It's a simple library that allows you to turn a class into a query string for https calls.

Usage

The implementation is available through a static class QueryStringComposer.

The two available overloads perform the same conversion.

Global configuration

You can use the method Configure provided by QueryStringComposerConfiguration in your service configuration to change the key case style globally.

QueryStringComposerConfiguration.Configure(options =>
{
    options.KeyNameCaseStyle = StringCaseStyle.TrainCase;
});

There are some supported style cases, they are:

public enum StringCaseStyle
{
    CamelCase = 1,
    PascalCase = 2,
    SnakeCase = 3,
    KebabCase = 4,
    TrainCase = 5
}

String overload

Code result: http://localhost?SomeName=Victor&SomeAge=20

const string baseUrl = "http://localhost";

var queryObject = new YourClass
{
    SomeName = "Victor",
    SomaAge = 20
};

var result = QueryStringComposer.Compose(baseUrl, queryObject);

Uri overload

Code result: http://localhost?SomeName=Victor,Juan&SomeAge=20,21

var uri = new Uri("http://localhost");

// Some Uri Changes

var queryObject = new YourClass
{
    SomeNames = new List<string> { "Victor", "Juan" },
    SomaAges = new List<int> { 20, 21 }
};

var result = QueryStringComposer.Compose(uri, queryObject);

Attributes

QueryStringKeyNameAttribute

In case you need to pass a custom value as a key and don't want to mess up your code with non-standard names. You can use the QueryStringKeyNameAttribute attribute for this.

Code result: http://localhost?user_name=Jorge

const string baseUrl = "http://localhost";

var queryObject = new YourClass
{
    UserName = "Jorge",
};

var result = QueryStringComposer.Compose(uri, queryObject);

class YourClass
{
    [QueryStringKeyName("user_name")]
    public string UserName { get; set; }
}

QueryStringIgnoreAttribute

In case you only need to ignore one property and don't want to create a new class for it. You can use the QueryStringIgnoreAttribute attribute for this.

Code result: http://localhost?Login=victorvhn

const string baseUrl = "http://localhost";

var queryObject = new YourClass
{
    Login = "victorvhn",
    Password = "d74ff0ee8da3b9806b18c8"
};

var result = QueryStringComposer.Compose(uri, queryObject);

class YourClass
{
    public string Login { get; set; }

    [QueryStringIgnore]
    public string Password { get; set; }
}

QueryStringKeyCaseStyleAttribute

In case you need to change the key case style of a single property and don't want to change it globally. You can use the QueryStringKeyCaseStyleAttribute attribute for this.

Code result: http://localhost?Key-In-Train-Case=value

const string baseUrl = "http://localhost";

var queryObject = new YourClass
{
    KeyInTrainCase = "value",
};

var result = QueryStringComposer.Compose(uri, queryObject);

class YourClass
{
    [QueryStringKeyCaseStyleAttribute(StringCaseStyle.TrainCase)]
    public string KeyInTrainCase { get; set; }
}

Attention when using

Some types are not supported for conversion:

• Complex Lists.
• Complex Dictionaries.

Providing a dictionary to compose, the values will not be converted.

Code result: http://localhost?key1=value1&key2=value2

const string baseUrl = "http://localhost";

var dic = new Dictionary<string, string>
{
    { "key1", "value1" },
    { "key2", "value2" }
};

var result = QueryStringComposer.Compose(baseUrl, dic);
