我在ColdFusion中編寫了一個Web服務,它通過檢查數據庫中的輸入值來返回消息(成功/失敗)。 要運行CFC,我直接提供的參數中的URL,就像這樣: http://localhost/AimsWeb/Authenticate2.cfc?method=AuthenticateUser&returnformat=json&CustomerID=1&username=xxx&password=xxxx 但是當我運行這個頁面,它有錯誤,如下面的結尾: 執行cfc時出錯:從函數返回的值不是json類型
這是我的CFC:
<cfcomponent rest="true" restpath="/AimsWeb"> <!--- REST Service--->
<cffunction name="AuthenticateUser" access="remote" httpmethod="POST" returnFormat="JSON" returntype="json">
<!---- Defining Arguments--->
<cfargument name="Username" type="string" required="Yes">
<cfargument name="Password" type="string" required="Yes">
<cfargument name="CustomerID" type="string" required="Yes">
<!---- Setting the Form Values (which we will get from AW+) and setting it to arguments passed--->
<cfset Form.CustomerID = arguments.CustomerID>
<cfset Form.Username = arguments.Username>
<cfset Form.Password = Hash(arguments.Password)>
<cfif StructKeyExists (form, 'CustomerID') and StructKeyExists(form, 'UserName') and StructKeyExists (form, 'password')>
<cfquery name="AllUsers" datasource="#Application.GomDatasource#">
SELECT u.UserTypeID, u.UserID, u.CustomerID, u.UserName, u.Password
FROM tblUsers u
WHERE u.CustomerID = <cfqueryparam cfsqltype="cf_sql_integer" value="#Form.CustomerID#">
</cfquery>
<!--- This is to check whether provided parameters are valid by checking the same in the database--->
<cfset local.StatusStruct = StructNew()>
<cfif form.customerid EQ "" OR form.username EQ "" OR form.password EQ "">
<cfset local.StatusStruct['errorCode'] = 400>
<cfset local.StatusStruct['errorMessage'] = "Insufficient Input.">
<cfelseif AllUsers.RecordCount AND form.CustomerId EQ AllUsers.CustomerID AND form.username EQ AllUsers.UserName AND form.password EQ AllUsers.Password>
<cfset local.StatusStruct['errorCode'] = 200>
<cfset local.StatusStruct['errorMessage'] = "Success">
<cfelseif AllUsers.CustomerID NEQ form.CustomerID>
<cfset local.StatusStruct['errorCode'] = 400>
<cfset local.StatusStruct['errorMessage'] = "Customer Id doesn't exist">
<cfelseif AllUsers.UserName NEQ form.UserName>
<cfset local.StatusStruct['errorCode'] = 400>
<cfset local.StatusStruct['errorMessage'] = "User not found">
<cfelseif AllUsers.Password NEQ form.password>
<cfset local.StatusStruct['errorCode'] = 400>
<cfset local.StatusStruct['errorMessage'] = "Invalid Password">
</cfif>
<!--- Returning the status in JSON form--->
</cfif>
<cfreturn local.StatusStruct>
</cffunction>
</cfcomponent>
任何人都可以幫助我嗎?
您將local.StatusStruct轉換爲json的地方在哪裏? –
URL中的用戶名和密碼...爲什麼? – Hackerman
@DanBracuk:我相信如果我們指定returnFormat =「json」,這會自動將返回值轉換爲JSON字符串..(?) – Vasu
