尝试点击以下http-auth代码:
var auth = require("http-auth");
var basic = auth.basic({
realm: "Authentication required",
file: __dirname + "/../htpasswd"
});
http.createServer(basic, onRequest).listen(port);
以下是使用request library nodejs命中上述逻辑的代码段:
var request = require('request'),
username = "username",
password = "password",
url = "http://localhost:3000/",
auth = "Basic " + new Buffer(username + ":" + password).toString("base64");
request(
{
url : url,
headers : {
"Authorization" : auth
}
},
function (error, response, body) {
console.log("body "+body);
console.log("response "+response);
console.log("error "+error);
}
);
输出:
回复:未定义
body: undefined
错误:套接字挂断

onRequest方法:
module.exports.start = function(route, handle) {
function onRequest(request, response){
// response.write("welcome "+request.user+"!");
var pathname = url.parse(request.url).pathname;
route(handle, pathname, request, response);
}// on request ends here
从app.js调用onRequest,如下所示:
var router = require("./lib/router.js");
var handle = {}
handle["/add"] = requestHandler.addMethod;
handle["/delete"] = requestHandler.deleteMethod;
handle["/edit"] = requestHandler.editMethod;
handle["/search"] = requestHandler.searchMethod;
console.log(router.route);
server.start(router.route, handle);
router.js
"use strict";
var url = require("url");
module.exports.route = function(handle, pathname, request, response) {
if(typeof handle[pathname] === 'function') {
handle[pathname](request, response);
} else {
console.log("no request handler found for "+pathname);
}// else ends here
}// route ends here
处理程序中的方法(requestHandler):
module.exports.addMethod = function (req, res) {
body = "";
req.on('data', function (chunk) {
body += chunk;
});
req.on('end', function () {
body = JSON.parse(body);
databaseConnection.collection("productList").insert(body, function(err,data) {
if(err){
res.writeHead(400, {"contentType":"application/JSON"});
var failedRes = JSON.stringify({
error : {
text : "Failed to add product"
}
});
res.end(faileRes);
return;
}// error handling
res.writeHead(200, {"Content-Type": "application/JSON"});
var finalId = data.ops[0]._id;
var successRes = JSON.stringify({
data: {
id : finalId
},
error : {
code : 0,
text : "Product added successfully"
}
});
res.end(successRes);
});
})
}
答案 0 :(得分:0)
由于服务器上出现JSON.parse
错误而发生错误。 body
对象是一个字符串,但它不是有效的JSON字符串。这导致行:
JSON.parse(body);
在服务器上抛出错误(如果没有发送数据):
SyntaxError:意外的输入结束
在Object.parse(native)
或者,如果发送了数据:
SyntaxError:意外的令牌......
在Object.parse(native)
这些错误中的任何一个都会导致服务器崩溃,从而导致客户端报告socket hang up
错误。
要解决此问题,您需要将数据作为JSON发送到服务器。要使用request
模块执行此操作:
request.post(url, {
headers: {
"Authorization" : auth
},
json: {
message: 'Hello'
}
}, function (error, response, body) {
console.log("body "+body);
console.log("response "+response);
console.log("error "+error);
});
