我有一個asmx web服務，它返回一個大陸的國家列表。當使用jQuery來調用Web服務使用：將asmx Web服務轉換爲WCF Web服務 - 爲什麼JSON參數需要額外的引號？
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "InternationalLookup.asmx/LoadCountries",
data: '{ continentName: "' + $(this).val() + '" }',
dataType: "json",
success: function (response) {
//..code
},
error: function (response) {
//..code
}
});
也能正常工作與ASMX代碼，但使用WCF服務時，我不得不將其更改爲：
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "InternationalLookup.svc/LoadCountries",
**data: '{ \"continentName\": "' + $(this).val() + '" }',**
dataType: "json",
success: function (response) {
//..code
},
error: function (response) {
//..code
}
});
注的區別我必須通過的數據，現在需要在大陸名稱周圍增加引號。我的WCF服務，它的配置：
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.serviceModel>
<behaviors>
<serviceBehaviors>
<behavior name="InternationalLookupBehavior">
<serviceMetadata httpGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="true" />
</behavior>
</serviceBehaviors>
<endpointBehaviors>
<behavior name="InternationalLookup">
<enableWebScript />
</behavior>
</endpointBehaviors>
</behaviors>
<services>
<service behaviorConfiguration="InternationalLookupBehavior"
name="USQ.Websites.RefreshLayout.Webservices.UsqInternationalLookup">
<endpoint address="" binding="wsHttpBinding" contract="IInternationalLookup">
<identity>
<dns value="localhost" />
</identity>
</endpoint>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
</service>
</services>
[ServiceContract]
public interface IInternationalLookup
{
[OperationContract]
[WebInvoke(Method = "POST", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)]
string LoadCountries(string continentName);
}
儘管有相當一些麻煩得到它的工作，我想知道爲什麼在WCF web服務的參數必須被包裹在額外的引號。
