我正在使用 node.js 和 spring web 服务。我在 tomcat 服务器上部署了 spring web 服务应用程序，并且节点正在运行。我正在使用将调用节点的 Web 应用程序，并且从节点调用 Spring REST Web 服务。我能够将 JSON 数据获取到节点中，但是在从节点调用 Spring REST Web 服务时出现以下错误：

以下是我的 node.js 代码：

    var express = require("express"), 
    app = express(), 
    http = require("http").createServer(app);
    var requestObj = require('request');  

    var responseBody = "";

    app.use(express.bodyParser());

    function getSample(token){
        requestObj({
                url : "http://127.0.0.1:8080/project/sample/get",
                method : "POST",
                headers : { "Content-Type" : "application/json","pubKey":token}
            },
            function (error, response, body) {
                responseBody=body;
            }
        );
        console.log("responseBody:= "+responseBody);
    }

    function something(token,jsonbody){
        console.log("jsonbody :- "+JSON.stringify(jsonbody));
        requestObj({
                url : "http://127.0.0.1:8080/project/something/childurl",
                method : "POST",
                headers : { "Content-Type" : "application/json","pubKey":token},
                bosy : JSON.stringify(jsonbody)
            },
            function (error, response, body) {
                responseBody=body;
            }
        );
        console.log("responseBody:= "+responseBody);
    }

    app.post('/samples', function(request, response){
        console.log(request.body);
        var methodName = request.method;
        var token = request.body.pubKey;
        console.log("Called method is :-"+methodName);
        if(methodName=="POST"){
            getSample(token);
        }
        response.send(responseBody);
    });


    app.post('/something', function(request, response){
        console.log(request.body);
        var methodName = request.method;
        var token = request.body.pubKey;
        console.log("Called method is :-"+methodName);
        if(methodName=="POST"){
            something(token,request.body);
        }
        response.send(responseBody);
    });


    app.listen(8088);

在功能something()中，您缺少body:参数。同样，如果您有 json 有效负载和响应，您应该使用json:true.

requestObj({
                url : "http://127.0.0.1:8080/project/something/childurl",
                method : "POST",
                headers : { "Content-Type" : "application/json","pubKey":token},
                body : JSON.stringify(jsonbody),
                json: true
            },
            function (error, response, body) {
                responseBody=body;
            }
        );
