在 Rest Web 服务问题中使用 JSON 进行 jQuery Ajax POST 调用

jQuery Ajax POST call with JSON in Rest Web Service Issue(在 Rest Web 服务问题中使用 JSON 进行 jQuery Ajax POST 调用)

问题描述

我想将一个 JSON 对象从我的页面发布到 Rest WS.但是，当我通过 jQuery ajax 调用作为输出发布 json 时，我得到了一个 HTML 页面，其中包含HTTP Status 405 - Method Not Allowed"的 JSON 状态，这是我从 Rest Web Service 发送的.请参考以下代码片段.

我使用的是 jquery 1.11.3 版本.

经过大量谷歌搜索，我找到了一些解决方案.现在我正在使用 HTTP-Proxy-Servlet.

我用我的 html 页面创建了一个 java web 应用程序，该页面有 ajax 调用，并且从我的 ajax 调用中我调用了同一个域的 URL.请参考我的 ajax 调用.

 $.ajax({url: "rest/api/crunchifyService/jsonpost",方法:POST"，数据:JSON.stringify(jsonObj)，数据类型:'json'，内容类型:应用程序/json"，成功:函数(结果，状态，jqXHR){//做一点事},错误(jqXHR，textStatus，errorThrown){//做一点事}});

现在我已经使用 org.mitre.dsmiley.httpproxy.ProxyServlet 完成了相同的域调用映射.请参考我的 web xml.

<servlet><servlet 名称>代理</servlet 名称><servlet-class>org.mitre.dsmiley.httpproxy.ProxyServlet</servlet-class><初始化参数><param-name>targetUri</param-name><param-value><!-- 跨域 URL 到这里--></param-value></初始化参数><初始化参数><参数名称>日志</参数名称><参数值>true</参数值></初始化参数></servlet><servlet 映射><servlet 名称>代理</servlet 名称><url-pattern>/rest/*</url-pattern></servlet 映射>

现在我的 ajax 正在调用这个 Proxy Servlet，它正在重定向到 CROS 目标 Rest Web 服务.

I want to post a JSON object from my page to a Rest WS. But when I am posting json through jQuery ajax call as output I am getting a HTML page with "HTTP Status 405 - Method Not Allowed" instate of JSON, which I am sending from Rest Web Service. Please refer the following code snippet.

I am using jquery 1.11.3 version.

http://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js

jQuery Ajax Call:

 $.ajax({
        url: "http://localhost:8080/MyWebService/api/myService/jsonpost",
        method: "POST",
        data: jsonObj,
        dataType: 'application/json',
        contentType: "application/json",
         success: function(result){
              alert(result);
         },
         error(){
             console.log('Error');
         }
    });

Please note my rest web service is running in my local tomcat.

Please find my Rest Web Service POST code.

@POST
@Path("/jsonpost")
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
public String crunchifyJsonPostREST(SampleVO input) throws JSONException{
    SampleVO sampleVO = input;
    return new Gson().toJson(sampleVO);
}

VO:

public class SampleVO {

private String name;

/**
 * @return the name
 */

@XmlElement
public String getName() {
    return name;
}

/**
 * @param name the name to set
 */
public void setName(String name) {
    this.name = name;
}

}

My Maven Dependency is:

    <dependency>
        <groupId>com.sun.jersey</groupId>
        <artifactId>jersey-server</artifactId>
        <version>1.8</version>
    </dependency>

    <dependency>
        <groupId>com.sun.jersey</groupId>
        <artifactId>jersey-json</artifactId>
        <version>1.8</version>
    </dependency>

Firebug Details:

Please find my ajax request Header.

Please find my ajax response and response HTML.

Need your help to resolve this issue.

Thanks is advance.

Solution:

After lot of googling I have found some solution. Now I am using HTTP-Proxy-Servlet.

I have crated a java web application with my html page which has the ajax call and from my ajax call I am calling a URL of same domain. Please refer my ajax call.

 $.ajax({
        url: "rest/api/crunchifyService/jsonpost",
        method: "POST",
        data: JSON.stringify(jsonObj),
        dataType: 'json',
        contentType: "application/json",
         success: function(result,status,jqXHR ){
              //Do something
         },
         error(jqXHR, textStatus, errorThrown){
             //Do something
         }
    }); 

Now I have done this same domain call mapping with org.mitre.dsmiley.httpproxy.ProxyServlet. Please refer my web xml.

<servlet>
    <servlet-name>proxy</servlet-name>
    <servlet-class>org.mitre.dsmiley.httpproxy.ProxyServlet</servlet-class>
    <init-param>
        <param-name>targetUri</param-name>
        <param-value><!-- Cross domain URL goes here --></param-value>
    </init-param>
    <init-param>
        <param-name>log</param-name>
        <param-value>true</param-value>
    </init-param>
</servlet>
<servlet-mapping>
    <servlet-name>proxy</servlet-name>
    <url-pattern>/rest/*</url-pattern>
</servlet-mapping>

Now my ajax is calling this Proxy Servlet and it is redirecting to the CROS destination Rest Web Service.
