从浏览器调用asmx Web服务

本文介绍了从浏览器调用asmx Web服务的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

您好b $ b 我正在使用 framework 4.0开发ASP.NET Web Forms应用程序 我想在我的应用程序中使用Web服务 - >可以从浏览器访问（通过输入URL） - >返回JSON 在我的网络配置文件中，我已经添加了

< webServices > < 协议 > < add 名称 = HttpGet / > < ; / protocols > < / webServices >

这是我的asmx服务的样子

[WebMethod] [ScriptMethod（UseHttpGet = true，ResponseFormat = ResponseFormat.Json）] public List< Department> BindDepartments（int faculty = 0，string university =，string branch =） { List< Department> departmentList = new List< Department>（）; DepartmentBL departmentBL = new DepartmentBL（）; try { JavaScriptSerializer js = new JavaScriptSerializer（）; Context.Response.Clear（）; Context.Response.ContentType =application / text; Context.Response.Write（js.Serialize（departmentBL.getDepartmentsByFaculty（faculty，university，branch）））; } catch（例外情况） { } 最后 { departmentBL = null; } return departmentList; }

使用此功能，当我从浏览器调用我的服务时，它返回XML和JSON的混合

[{DepartmentId：2，DepartmentName：Computer Science，DepartmentShortName： CS， FacultyId：3， FacultyName： 科学， 状态：假的， CreatedBy：0， CreatedTime： \ /日期（1406194645653）\ /， ModifiedBy： 0，ModifiedTime：\ / Date（-62135596800000）\ /}]<？xml version =1.0encoding =utf-8？> < ArrayOfDepartment xmlns：xsi =www.w3/2001/XMLSchema-instancexmlns：xsd =www.w3/2001/XMLSchemaxmlns = tempuri//>

如果我没有序列化并只返回我的C＃List对象，那么我将获得纯XML数据。 请在这里帮助我。我做错了什么？

解决方案

你将json结果写回响应并再次返回列表集合。 如何尝试这样做？

[WebMethod] [ScriptMethod（UseHttpGet = true ，ResponseFormat = ResponseFormat.Json） ] public string BindDepartments（ int faculty = 0 ， string university = ， string branch = ） { List< department> departmentList = new List< department>（）; DepartmentBL departmentBL = new DepartmentBL（）; 尝试 { JavaScriptSerializer js = new JavaScriptSerializer（）; Context.Response.Clear（）; Context.Response.ContentType = application / json; // json response // Context.Response.Write（js.Serialize（departmentBL.getDepartmentsByFaculty（faculty，university，branch）））; return js.Serialize（departmentBL.getDepartmentsByFaculty（faculty，university，branch））; } catch （例外情况） { } 最后 { departmentBL = null ; } // xml回复 // return departmentList; } < / department > < / 部门 >

Hi I am working on a ASP.NET Web Forms application using framework 4.0 I want to use web services in my application which will -> be accessible from a browser (by typing in the URL) -> return JSON In my web config file, I have already added

<webServices> <protocols> <add name="HttpGet"/> </protocols> </webServices>

Here is what my asmx service looks like

[WebMethod] [ScriptMethod(UseHttpGet = true, ResponseFormat = ResponseFormat.Json)] public List<Department> BindDepartments(int faculty = 0, string university = "", string branch = "") { List<Department> departmentList = new List<Department>(); DepartmentBL departmentBL = new DepartmentBL(); try { JavaScriptSerializer js = new JavaScriptSerializer(); Context.Response.Clear(); Context.Response.ContentType = "application/text"; Context.Response.Write(js.Serialize(departmentBL.getDepartmentsByFaculty(faculty, university, branch))); } catch (Exception ex) { } finally { departmentBL = null; } return departmentList; }

Using this, when I call my service from the browser, it returns a mix of XML and JSON

[{"DepartmentId":2,"DepartmentName":"Computer Science","DepartmentShortName":"CS","FacultyId":3,"FacultyName":"Science","Status":false,"CreatedBy":0,"CreatedTime":"\/Date(1406194645653)\/","ModifiedBy":0,"ModifiedTime":"\/Date(-62135596800000)\/"}]<?xml version="1.0" encoding="utf-8"?> <ArrayOfDepartment xmlns:xsi="www.w3/2001/XMLSchema-instance" xmlns:xsd="www.w3/2001/XMLSchema" xmlns="tempuri/" />

If I do not serialize and just return my C# List object, then I get pure XML data. Please help me out here. What am I doing wrong?

解决方案

You write json result to response and return list collection again. How about trying like this?

[WebMethod] [ScriptMethod(UseHttpGet = true, ResponseFormat = ResponseFormat.Json)] public string BindDepartments(int faculty = 0, string university = "", string branch = "") { List<department> departmentList = new List<department>(); DepartmentBL departmentBL = new DepartmentBL(); try { JavaScriptSerializer js = new JavaScriptSerializer(); Context.Response.Clear(); Context.Response.ContentType = "application/json"; //json response // Context.Response.Write(js.Serialize(departmentBL.getDepartmentsByFaculty(faculty, university, branch))); return js.Serialize(departmentBL.getDepartmentsByFaculty(faculty, university, branch)); } catch (Exception ex) { } finally { departmentBL = null; } //xml response //return departmentList; } </department></department>
