有时候使用webview需要查看发送的header信息是否正确发送，一般我们都是和后台配合来检验的。其实我们也可以自己来检验，自己启动一个node作为服务端，然后连接本地的node服务来查看header信息。 ``` var http = require('http'); var port = 9000; function logRequest(request) { console.log("request headers: ", request.headers) console.log("Processing request for: ", request.url) console.log('Time',new Date().toString()) } http.createServer(function(request, response) { response.writeHead(200, {"Content-Type":...

react native version mismatch

1

版本0.46升级0.51 然后使用codepush发布更新 可以检测更新也可以下载，在重启应用时报错如下 如图：   关机重启后，再次点击更新还是报这个错。 1：关掉其他项目，关掉node等其他窗口 2：执行watchman watch-del-all && react-native start --reset-cache 3：重新再这个环境下上传应用至服务器更新 然后更新成功.
