WCF Der Remote-Server hat eine unerwartete Antwort zurückgegeben: (400) Ungültige Anforderung

Question

Ich verwende das Protokoll basicHttpBinding für WCF.

Ich empfange große Class<T> (kein Problem).

Aber ich sende große Class<T> ich diesen Fehler

Ausnahme geworfen: 'System.ServiceModel.ProtocolException' in System.ServiceModel.Internals.dll

Zusätzliche Informationen: Der Remote-Server zurückgegeben ein unerwartet Antwort: (400) Ungültige Anforderung.

Mein Client-Code ist

Answer 1

Der Grund, warum Sie können ein großes Objekt in den Dienst nicht senden, weil Sie nie Ihre definiert zuweisen basicHttpBinding zu der Dienstendpunkt

In Ihrem Service Config, Sie haben:

<bindings> 
    <basicHttpBinding> 
    <binding name="NewBinding0"..... 

Aber dann, wenn Sie den Endpunkt definieren, können Sie nicht zuordnen "NewBinding0", um es:

<endpoint behaviorConfiguration="myHttpBindingEndPointBihaviour" 
     binding="basicHttpBinding" bindingConfiguration="".... 

Da das bindingConfiguration Element doesn Wenn Sie keine Bindungskonfiguration angeben, werden die Standardwerte für basicHttpBinding verwendet. Aus diesem Grund können Sie keine großen Objekte senden.

Weisen Sie den „NewBinding0“ zu Ihrem Endpunkt über das bindingConfiguration Attribut wie folgt aus:

<endpoint behaviorConfiguration="myHttpBindingEndPointBihaviour" 
     binding="basicHttpBinding" bindingConfiguration="NewBinding0"..... 

Und Ihre Dienstleistung sollte größere Objekte erhalten können, wenn der Kunde sie sendet.
