Unity3D网络通信（精编版）

1、unity3d网络通信自己写的测试demo ，一个功能一个功能测试着做的， 没有什么结构，凑合看吧。http协议，在手机平台，url必须必带http:/ 头。此脚本主要实现了分别用 pose和 get方式获取天气预报信息（ xml格式）。解析 xml获取网络图片获取网络图片（ base64格式）base64与 byte互转 byte 与 texture2d（图片）互转更多常用 webservice：using unityengine;using system.collections;using system.collections.generic;using system.xml;using

2、system.io;public class httpdemo : monobehaviourpublic string hostname = ""/ 城市天气预报服务public string urlpath ="/webservices/weatherwebservice.asmx/getweatherbycityname"/获得验证码服务（直接获得图片） private string picturename = "/webservices/validatecodewebservice.asmx/cnvalidateimage?bystri

3、ng='picture'"/获得验证码服务 （获得图片字节流）private string picturebytename = "/webservices/validatecodewebservice.asmx/cnvalidatebyte?bystring='picbyte'"private texture2d mpicture;private texture2d mpicturebyte;private texture2d mconvertpng; public string parameters = new string &q

4、uot;thecityname" ; private string xmlcontent = "null"public stringtestc = "null"void ongui()/ 显示测试信息gui.label(new rect(100, 10, 1000, 38), testc);/ 表单传值if (gui.button(new rect(10, 50, 100, 60), "post")postweatherbycityname("北京");gui.button(new rect(120, 8

5、0, 100 + getjindu() * 100, 20), (getjindu() * 100) + "%");/get传值（ android平台不支持中文参数）if(gui.button(new rect(10, 130, 100, 60), "get")getweatherbycityname("58367");/上gui.button(new rect(120, 150,海100 + getjindu() * 100, 20), (getjindu() * 100) + "%");/显示读取到的天气预报原

6、始信息（xml格式）gui.label(new rect(10, 220, 380, 500), mcontent);/解析 xmlif (gui.button(new rect(500, 200, 120, 60), "analysisxml")xmlcontent = analysisxml(); gui.label(new rect(410, 220, 380, 500), xmlcontent);/下载网络图片if (gui.button(new rect(10,750, 80, 60), "downpic")downloadpicture(pi

7、cturename);gui.label(new rect(100, 760, 200, 200),mpicture);/ 下载网络图片（ base64格式）if (gui.button(new rect(350, 750, 80, 60), "downpicbyte")downloadpicturebyte(picturebytename);gui.label(new rect(450, 760, 200, 200), mpicturebyte);public voidpostweatherbycityname(string str)/ 将参数集合封装到dictionar

8、y集合方便传值dictionary<string, string> dic = newdictionary<string, string>();/参数dic.add(parameters0, str);startcoroutine(post(hostname + urlpath , dic);public void getweatherbycityname(string str)/ 将参数集合封装到dictionary集合方便传值dictionary<string, string> dic = new dict

9、ionary<string, string>();/参数dic.add(parameters0, str);startcoroutine(get(hostname + urlpath , dic);/下载图片public void downloadpicture(string picname)testc ="picurl = " + picname;startcoroutine(gettexture(hostname + picname);/下载图片（字节流） public void downloadpicturebyte(string picn

10、ame)startcoroutine(gettexturebyte(hostname + picname);/*-helper-*/private float mjindu = 0;private string mcontent; public float getjindu()returnmjindu;/post请求 (form表单传值、 效率低、安全， )ienumerator post(string url, dictionary<string, string> post)/ 表wwwform form = new wwwform();单/从集合中取出所有参数，

11、设置表单参数（addfield().foreach (keyvaluepair<string, string> post_arg in post)form.addfield(post_arg.key, post_arg.value);/ 表单传值，就是postwww www = new www(url, form);yield return www;mjindu = gress;if (www.error != null)/post请求失败mcontent ="error :" +www.error;else/post请求成功mco

12、ntent = www.text;/get 请求（ url? 传值、效率高、不安全）ienumerator get(string url, dictionary<string, string> get)string parameters;bool first;if (get.count > 0)first = true; parameters = "?"/ 从集合中取出所有参数， 设置表单参数（addfield().foreach (keyvaluepair<string, string> post_ar

13、g in get)if (first)first = false;elseparameters += "&"parameters+= post_arg.key + "=" +post_arg.value;elseparameters = ""testc ="geturl :" +parameters;/ 直接 url传值就是getwww www = new www(url + parameters);yield return www;mjindu = gress;if (www.err

16、ad(new stringreader(www.text);/通过索引查找子节点picbyte =xmldoc.getelementsbytagname("base64binary").item(0).innertext;testc = picbyte;mpicturebyte = bttetopic(picbyte);/解析 xmlstring analysisxml()string str = ""xmldocument xmldoc = new xmldocument();xmldoc.load(new stringreader(mcontent)
