Serialise an object to URL parameter string - Including properties from nested objects

问题

I have a class which contains a property who's type is another class. For example:

public class Outer
{
    public string SomeStringProperty { get; set; }
    public Inner SomeClassProperty { get; set; }
}

public class Inner
{
    public string InnerProperty1 { get; set; }
    public string InnerProperty2 { get; set; }
}

I want to convert an instance of the Outer class to a URL query string, and include the properties from the nested Inner class.

For example, given an instance of Outer, such as:

Outer toSerialise = new Outer 
{
    SomeStringProperty = "MyOuterValue",
    SomeClassProperty = new Inner
    {
        InnerProperty1 = "MyInnerValue1",
        InnerProperty2 = "MyInnerValue2"
    }
};

I want to convert this to a string of:

&SomeStringProperty=MyOuterValue&InnerProperty1=MyInnerValue1&InnerProperty2=MyInnerValue2

How can I achieve this?

I've found answers to similar questions, however they don't seem to support nested classes.

回答1:

We had same problem with callback url's client state in Oauth2 because callback urls have ampersand & too

http://.......?param=123&param2=456&state=?id=1&name=test

We just converted callback url to Base64 encoded string and decoded at service itself.

http://.......?param=123&param2=456&state=P2lkPTEmbmFtZT10ZXN0

Fix:

Encode your class instance as json
Encode json as base64string
Send base64string in url as data param
Decode base64 and map json into your model at your api.

JSON:

 { "menu": {
  "id": "file",
  "value": "File",
  "popup": {
    "menuitem": [
      {"value": "New", "onclick": "CreateNewDoc()"},
      {"value": "Open", "onclick": "OpenDoc()"},
      {"value": "Close", "onclick": "CloseDoc()"}
    ]
  }
}}

Base64:

Url:

&data=eyJtZW51IjogewogICJpZCI6ICJmaWxlIiwKICAidmFsdWUiOiAiRmlsZSIsCiAgInBvcHVwIjogewogICAgIm1lbnVpdGVtIjogWwogICAgICB7InZhbHVlIjogIk5ldyIsICJvbmNsaWNrIjogIkNyZWF0ZU5ld0RvYygpIn0sCiAgICAgIHsidmFsdWUiOiAiT3BlbiIsICJvbmNsaWNrIjogIk9wZW5Eb2MoKSJ9LAogICAgICB7InZhbHVlIjogIkNsb3NlIiwgIm9uY2xpY2siOiAiQ2xvc2VEb2MoKSJ9CiAgICBdCiAgfQp9fQ==

Alternative :

If you must use this query format then you can also use delegate types

Outer toSerialise = new Outer 
{
    SomeStringProperty = "MyOuterValue",
    SomeClassProperty = new Inner
    {
        InnerProperty1 = "MyInnerValue1",
        InnerProperty2 = "MyInnerValue2"
    }
};

var queryObject = new { toSerialise.SomeStringProperty, toSerialise .Inner.InnerProperty1, toSerialise.Inner.InnerProperty2 }
