我正在使用 PhoneGap 开发一个移动应用程序,其中一个功能涉及将图像上传到 Web 服务进行处理。我编写了一个托管在 IIS 中的 WCF 服务来接受图像,其合同如下所示:
[ServiceContract]
public interface IImages
{
[OperationContract(Name="UploadImage")]
[WebInvoke(UriTemplate = "?file_key={fileKey}", Method = "POST", BodyStyle = WebMessageBodyStyle.Bare)]
ImageResource UploadImage(string fileKey, Stream imageStream);
}
我的 web.config 中的配置部分如下所示:
<system.serviceModel>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true">
<serviceActivations>
<add service="Services.Images" relativeAddress="images.svc" />
</serviceActivations>
</serviceHostingEnvironment>
<services>
<service behaviorConfiguration="DefaultServiceBehavior" name="Services.Images">
<endpoint behaviorConfiguration="DefaultEndpointBehavior" binding="webHttpBinding" bindingConfiguration="PublicStreamBinding" contract="Services.Contracts.IImages" />
</service>
</services>
<bindings>
<webHttpBinding>
<binding name="PublicStreamBinding"
maxReceivedMessageSize="2000000000" transferMode="Streamed">
<security mode="None" />
</binding>
</webHttpBinding>
</bindings>
<behaviors>
<endpointBehaviors>
<behavior name="DefaultEndpointBehavior">
<webHttp helpEnabled="true" />
</behavior>
</endpointBehaviors>
<serviceBehaviors>
<behavior name="DefaultServiceBehavior">
<serviceMetadata httpGetEnabled="false" />
<serviceDebug includeExceptionDetailInFaults="true" />
<serviceThrottling maxConcurrentCalls="30" maxConcurrentInstances="30" />
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
当我尝试使用 PhoneGap 的 FileTransfer 类将文件上传到端点时,从服务返回的响应是 405 Method Not Allowed。我在这里做错了什么?
更新:我的移动应用程序中上传文件的功能如下。此代码以前在指向较旧的 ASMX 服务时运行良好。
ns.UploadImage = function(){
//alert(ns.Dictionary['LocalImagePath']);
var uri = ns.Dictionary['LocalImagePath'];
try {
var options = new FileUploadOptions();
options.fileKey = uri.substr(uri.lastIndexOf('/')+1) + ".jpeg";
options.fileName = uri.substr(uri.lastIndexOf('/')+1) + ".jpeg";
options.mimeType = "image/jpeg";
var ft = new FileTransfer();
ft.upload(uri, GetServerUrl()+"images.svc?file_key="+options.fileKey, ns.UploadImageSuccess, ns.UploadImageError, options);
} catch (e) {
ns.UploadImageError(e);
}
};
