无法使用其他项目中的jQuery调用Web服务 [英] Unable to call webservice using jquery from another project

问题描述

下午好！

我已经在新项目中创建了Web服务
返回Json数据的公共字符串GetProductsJson(字符串前缀)
我正在通过另一个项目使用这样的jquery来调用该Webservice

Hi Good Afternoon!

I have created webservice in new project
public string GetProductsJson(string prefix)which is returning Json data
and I am calling that webservice by using jquery like this from another project

$.ajax({

    type: "POST",
    url:"http://localhost:3904/Service1.asmx/GetProductsJson",
    data: "{'prefix':'" + $(this).val() + "'}",
    contentType: "application/json; charset=utf-8",
    dataType: "json",
    crossDomain:true,
    success: function(response) {
//getting data by using (response.d)
},
error: function(request, status, error) {
                        alert(request.responseText);
                    }
});

我使用了不同的网址

http://localhost:3904/Service1.asmx/GetProductsJson
http://localhost:3904/Service1.asmx?GetProductsJson
http://localhost:3904/Service1.asmx?op = GetProductsJson

但我没有得到任何回应.


如果我把Service&单个项目中的客户端代码即可正常工作.

请帮帮我..

I have used different-different url

http://localhost:3904/Service1.asmx/GetProductsJson
http://localhost:3904/Service1.asmx?GetProductsJson
http://localhost:3904/Service1.asmx?op=GetProductsJson

but I am not getting any response.


If I put Service & Client code in single project then it works fine.

Please help me..

推荐答案

.ajax({ 类型:" ， url:" ， 数据:" +

.ajax({ type: "POST", url:"http://localhost:3904/Service1.asmx/GetProductsJson", data: "{'prefix':'" +

(此).val()+ " ， contentType:" ， dataType:" ， crossDomain: true ， 成功:功能(响应){ // 使用(response.d)获取数据 }， 错误:功能(请求，状态，错误){ alert(request.responseText); } });

(this).val() + "'}", contentType: "application/json; charset=utf-8", dataType: "json", crossDomain:true, success: function(response) { //getting data by using (response.d) }, error: function(request, status, error) { alert(request.responseText); } });

我使用了不同的网址

http://localhost:3904/Service1.asmx/GetProductsJson
http://localhost:3904/Service1.asmx?GetProductsJson

如果从另一个项目调用该Web服务，该Web服务是通过Visual Studio还是通过IIS运行?当它通过Visual Studio运行时，运行它的服务将分配一个唯一的端口(在这种情况下为3904)，但是通过IIS，您需要删除该端口(因此:http://localhost/Service1.asmx?...)

快速测试:在VS中打开Web服务项目并启动它(在窗口右侧状态栏中的下面，您将收到一条消息，表明它正在运行)离开项目，然后打开包含JQuery项目的其他项目.运行它.

希望这会有所帮助.

If you call the webservice from another project is that webservice running via Visual Studio or via IIS? When it runs via visual studio the service that runs it will assign a unique port (3904 in this case), but through IIS you need to remove the port (thus: http://localhost/Service1.asmx?...)

A quick test: open the webservice project in VS and launch it (below in the status bar on the right in window you should get a message that it is running) Leave the project runnning and open your other project containing the JQuery project. Run it.

Hope this helps.
