Web API Source Profiling default configuration (httpconfiguration)

We described the global configuration and initialization in the previous section. In this section, we will expand on the configuration read-only property of the globally configured, which is a type of httpconfiguration. It does some of the most basic work on the Web API for the entire API, such as defining default

1. routing Table (Routes)
2. Filter (Filters)
3. Default Message Handler (Messagehandlers)
4. Property Dictionary (properties)
5. Dependency Injection Decoupling (dependencyresolver)
6. Error handling policy (includeerrordetailpolicy)
7. Services (services, where the service is the interface and implementation for the services of the Web ApI framework)
8. Media Format Program (formatters)
9. The parameter binding rule (Parameterbindingrules).

The above is the configured properties. Next, you will expand on some properties.

Formatters

The default formatter, which is a mediatypeformattercollection type.

4 default formats are defined in the API:

1. Jsonmediatypeformatter: The corresponding is used to handle the request header is Application/json or Text/json format,
2. Xmlmediatypeformatter: Corresponds to the application/xml format that is used to process the request header
3. Formurlencodedmediatypeformatter: The corresponding is used to handle the request header is application/x-www-form-urlencoded,
4. Jquerymvcformurlencodedformatter

Services

The default service definition is as follows:

Public defaultservices (httpconfiguration configuration)
{
if (configuration = = null)
{
Throw Error.argumentnull ("configuration");
}

_configuration = Configuration;

          //Initialize the dictionary with all known service types, even if the list for this service type is
          //Empty , because we'll throw if the developer tries to read or write unsupported types.

           setsingle<iactionvaluebinder> (new Defaultactionvaluebinder ());
           setsingle<iapiexplorer> (New Apiexplorer ( Configuration));
           setsingle<iassembliesresolver> (new Defaultassembliesresolver ());
           setsingle<ibodymodelvalidator> (new Defaultbodymodelvalidator ());
           setsingle<icontentnegotiator> (new Defaultcontentnegotiator ());
           setsingle<idocumentationprovider> (null); Missing

Setmultiple<ifilterprovider> (New Configurationfilterprovider (),
New Actiondescriptorfilterprovider ());

Setsingle<ihostbufferpolicyselector> (NULL);
Setsingle<ihttpactioninvoker> (New Apicontrolleractioninvoker ());
Setsingle<ihttpactionselector> (New Apicontrolleractionselector ());
Setsingle<ihttpcontrolleractivator> (New Defaulthttpcontrolleractivator ());
Setsingle<ihttpcontrollerselector> (new Defaulthttpcontrollerselector (configuration));
Setsingle<ihttpcontrollertyperesolver> (New Defaulthttpcontrollertyperesolver ());
Setsingle<itracemanager> (New Tracemanager ());
Setsingle<itracewriter> (NULL);

This was a priority list. So put the most common binders at the top.
Setmultiple<modelbinderprovider> (New Typeconvertermodelbinderprovider (),
New Typematchmodelbinderprovider (),
New Keyvaluepairmodelbinderprovider (),
New Complexmodeldtomodelbinderprovider (),
New Arraymodelbinderprovider (),
New Dictionarymodelbinderprovider (),
New Collectionmodelbinderprovider (),
New Mutableobjectmodelbinderprovider ());
Setsingle<modelmetadataprovider> (New Dataannotationsmodelmetadataprovider ());
Setmultiple<modelvalidatorprovider> (New Dataannotationsmodelvalidatorprovider (),
New Datamembermodelvalidatorprovider ());

This is a ordered list,so put the most common providers at the top.
Setmultiple<valueproviderfactory> (New Querystringvalueproviderfactory (),
New Routedatavalueproviderfactory ());

Modelvalidatorcache Validatorcache = new Modelvalidatorcache (New lazy<ienumerable<modelvalidatorprovider> > (() = this. Getmodelvalidatorproviders ()));
Setsingle<imodelvalidatorcache> (Validatorcache);

Setsingle<iexceptionhandler> (New Defaultexceptionhandler ());
Setmultiple<iexceptionlogger> ();

_servicetypessingle = new hashset<type> (_defaultservicessingle.keys);
_servicetypesmulti = new hashset<type> (_defaultservicesmulti.keys);

Reset the caches and the known dependency scope
Resetcache ();
}

Default action binding rule: Parameterbindingrules

Parameterbindingrules = Defaultactionvaluebinder.getdefaultparameterbinders ();
