我尝试使用Restify和Postman发送Post数据来发送请求。
但无论我通过Post发送什么数据，都会收到以下错误：

这是我清理过的代码...... 的 API.js
const baseRouter = require('./routes/BaseRoutes');
const restify = require('restify'),
restifyPlugin = require('restify').plugins,
chalk = require('chalk'),
util = require('util'),
compression = require('compression');

const server = restify.createServer({
name: "Test API",
version: "1.0.0",
url: "localhost"
});
server.pre(restify.pre.sanitizePath()); // sanitizePath: cleans up duplicate or trailing / on the URL
server.pre(function (req, res, next) {
logger.silly(chalk.yellow.bold(`Request:\n${req}`));
return next();
});
// The "use" handler chains is executed after a route has been chosen to service the request
server.use(compression()); // compress all responses
server.use(restifyPlugin.acceptParser(server.acceptable)); // Accept header
server.use(restifyPlugin.authorizationParser()); // Authorization header
server.use(restifyPlugin.dateParser()); // expires requests based on current time + delta
server.use(restifyPlugin.queryParser({ mapParams: true })); // Parses URL query paramters into req.query
server.use(restifyPlugin.jsonp()); // parses JSONP callback
server.use(restifyPlugin.gzipResponse()); // gzips the response if client accepts it
server.use(restifyPlugin.bodyParser()); // parses POST bodies to req.body
server.use(restifyPlugin.jsonBodyParser({ mapParams: true })); // parses JSON POST bodies to req.body

// When a client request is sent for a route that exist, but has a content-type mismatch, restify will emit this event.

server.on('InvalidContent', function (req, res, err, cb) {
console.log("line 122");
logger.error(chalk.red.bold(util.inspect(err)));
res.send();
});
// Emitted after a route has finished all the handlers you registered. You can use this to write audit logs, etc. The route parameter will be the Route object that ran.
server.on('after', function (req, res, route) {

BaseRoutes.js
const chalk = require('chalk'),
util = require('util'),
_Router = require('restify-router').Router,
router = new _Router(),
errors = require('restify-errors');
function hello(req, res, next) {
if (!req.is('application/json')) {
return next(new errors.InvalidContentError("Expects 'application/json'"));
}
logger.info(chalk.yellow.bold(`Requested route: /api/v1/hello`));
res.send('ok');
next();
}
router.post({path: '/hello', version: '1.0.0'}, hello);
module.exports = router;
这是我发布的JSON
{
"name": "John Smith"
}
正如你所看到的 - 我没有做任何与众不同的事情......但是我遇到了错误的＃34;＆＃39;无效的JSON：在位置1的JSON中出现意外的令牌o＆＃ 39;＆＃34;
我错过了什么？
答案 0 :(得分：0)
您不能同时使用bodyParser和jsonBodyParser中间件 - 您必须选择其中一个。
我遇到了同样的错误消息，当我删除了bodyParser中间件并且只使用了jsonBodyParser时，错误就消失了 - 我的猜测是bodyParser正在做某事操纵请求体，以便jsonBodyParser获取它时，它不再是格式良好的JSON，并且无法正确解析。
