非常感谢您的光临。我刚开始使用Arduino无线传感器项目，但遇到了麻烦。如果您有任何见解或对我的项目进行故障排除，我将不胜感激。
我正在使用Arduino Mega和Wifi Shield，尝试将4个 channel (所有 float )上传到我的Xively Feed中。我正在使用基本教程脚本的修改形式(底部代码)。我验证并成功上传。当我运行电路板时，初始调试信息看起来不错。当我尝试使用Xively客户端库进行放置或获取操作时，出现错误(ret = -1，没有可用的套接字，并且获取时出现http错误)。我还在底部附加了错误的串行日志。
我已经采取了一些故障排除步骤。我已经重新下载了所有xively库和Wifi库，以确保。我认为手动设置DNS服务器(8.8.8.8)可能会有所帮助。我什至导入了整个arduino库(尽管我认为这不是必需的)以获取DNS功能。它似乎没有什么区别，所以我把它留在了故障排除过程中。另外，作为故障排除步骤，我添加了一个Xively client.get，以查看是否可以拉动但不能插入。那产生了一个HTTP错误。我还向我的项目添加了一个公共(public)开放的api key ，并尝试了该 key (而不是私有(private) key )。仍然没有喜悦。
虽然我已成功连接到wifi，但无法与任何服务建立真正的连接。我希望我错过了一些非常明显的步骤。我真的可以使用一条有用的线索使我再次走上正确的道路。谢谢!

This script was written for the MEGA 2560 with the wireless shield, connecting in to Xively's cloud graph service
The Mega 2560 with the Wireless shield and Probes uses the following pins:
* SPI bus interface
* Onboard MicroSD card reader (uses SD Lib) on digital pin 4
* Digital Pins 7, 50, 51, 52, and 53 are reserved and shouldn't be used
* Digital Pin 18 is set to OUTPUT to power the temp probe on/off
* Atlas Scientific Temp Sensor input on Analog Uno pin A4
* Phidgets Ph Sensor input on Analog Uno pin A2
* Phidgets ORD Sensor input on Analog Uno pin A0

最佳答案
感谢您为您的问题提供了如此多的背景知识，它使您可以轻松地测试并弄清楚您的问题是什么。只要您可以正常连接到wifi，就可以看到您的代码应该不错，除了所有导入。我要做的就是删除您一开始就有的多余导入。关于设置自己的DNS服务器，您可以执行此操作，但这可能是导致问题的原因。如果您担心DNS，则最好手动设置IP，而不要依赖DNS。
以下是我从您的代码中复制的内容的改编版本。希望它可以与您的网络和供稿一起使用。我在带有官方Arduino WiFi防护罩的UNO和Mega ADK(只有我拥有的Mega)上进行了测试，并且在这两者上均可使用。
