Unity3D網(wǎng)絡(luò)通信（精編版）

1、unity3d 網(wǎng)絡(luò)通信自己寫(xiě)的測(cè)試demo ，一個(gè)功能一個(gè)功能測(cè)試著做的，沒(méi)有什么結(jié)構(gòu)，湊合看吧。http 協(xié)議，在手機(jī)平臺(tái)，url 必須必帶http:/ 頭。此腳本主要實(shí)現(xiàn)了分別用 pose 和 get 方式獲取天氣預(yù)報(bào)信息（xml 格式） 。解析 xml 獲取網(wǎng)絡(luò)圖片獲取網(wǎng)絡(luò)圖片（base64 格式）base64 與 byte互轉(zhuǎn) byte 與 texture2d （圖片）互轉(zhuǎn)更多常用 webservice ：http:/ using unityengine; using system.collections; using system.collections.generic; usin

2、g system.xml; using system.io; public class httpdemo : monobehaviour public string hostname = http:/; /城市天氣預(yù)報(bào)服務(wù)public string urlpath = /webservices/weatherwebservice.asmx/getweatherbycityname; /獲得驗(yàn)證碼服務(wù)（直接獲得圖片）private string picturename = /webservices/validatecodewebservice.asmx/cnvalidateimage?bystr

3、ing=picture; /獲得驗(yàn)證碼服務(wù) （獲得圖片字節(jié)流）private string picturebytename = /webservices/validatecodewebservice.asmx/cnvalidatebyte?bystring=picbyte; private texture2d mpicture; private texture2d mpicturebyte; private texture2d mconvertpng; public string parameters = new string thecityname ; private string xmlc

4、ontent = null; public string testc = null; void ongui() /顯示測(cè)試信息gui.label(new rect(100, 10, 1000, 38), testc); /表單傳值if (gui.button(new rect(10, 50, 100, 60), post) postweatherbycityname(北京); gui.button(new rect(120, 80, 100 + getjindu() * 100, 20), (getjindu() * 100) + %); /get 傳值（ android 平臺(tái)不支持中文參數(shù)）

5、if (gui.button(new rect(10, 130, 100, 60), get) getweatherbycityname(58367);/上海 gui.button(new rect(120, 150, 100 + getjindu() * 100, 20), (getjindu() * 100) + %); /顯示讀取到的天氣預(yù)報(bào)原始信息（xml 格式）gui.label(new rect(10, 220, 380, 500), mcontent); /解析 xml if (gui.button(new rect(500, 200, 120, 60), analysisxml

6、) xmlcontent = analysisxml(); gui.label(new rect(410, 220, 380, 500), xmlcontent); /下載網(wǎng)絡(luò)圖片if (gui.button(new rect(10, 750, 80, 60), downpic) downloadpicture(picturename); gui.label(new rect(100, 760, 200, 200), mpicture); /下載網(wǎng)絡(luò)圖片（base64 格式）if (gui.button(new rect(350, 750, 80, 60), downpicbyte) down

7、loadpicturebyte(picturebytename); gui.label(new rect(450, 760, 200, 200), mpicturebyte); public void postweatherbycityname(string str) /將參數(shù)集合封裝到dictionary 集合方便傳值dictionary<string, string> dic = new dictionary<string, string>(); /參數(shù)dic.add(parameters0, str); startcoroutine

8、(post(hostname + urlpath , dic); public void getweatherbycityname(string str) /將參數(shù)集合封裝到dictionary集合方便傳值dictionary<string, string> dic = new dictionary<string, string>(); /參數(shù)dic.add(parameters0, str); startcoroutine(get(hostname + urlpath , dic); /下載圖片public void downloadp

9、icture(string picname) testc =picurl = + picname; startcoroutine(gettexture(hostname + picname); /下載圖片（字節(jié)流）public void downloadpicturebyte(string picname) startcoroutine(gettexturebyte(hostname + picname); /*-helper-*/ private float mjindu = 0; private string mcontent; public float getjindu() return

10、 mjindu; /post 請(qǐng)求 (form 表單傳值、 效率低、安全，) ienumerator post(string url, dictionary<string, string> post) /表單wwwform form = new wwwform(); /從集合中取出所有參數(shù)，設(shè)置表單參數(shù)（addfield(). foreach (keyvaluepair<string, string> post_arg in post) form.addfield(post_arg.key, post_arg.value); /表單傳值，

11、就是post www www = new www(url, form); yield return www; mjindu = gress; if (www.error != null) /post 請(qǐng)求失敗mcontent = error : + www.error; else /post 請(qǐng)求成功mcontent = www.text; /get請(qǐng)求（ url? 傳值、效率高、不安全）ienumerator get(string url, dictionary<string, string> get) string parameters; bool

12、 first; if (get.count > 0) first = true; parameters = ?; /從集合中取出所有參數(shù)，設(shè)置表單參數(shù)（ addfield(). foreach (keyvaluepair<string, string> post_arg in get) if (first) first = false; else parameters += & parameters += post_arg.key + = + post_arg.value; else parameters = ; testc =getu

13、rl : + parameters; /直接 url 傳值就是 get www www = new www(url + parameters); yield return www; mjindu = gress; if (www.error != null) /get 請(qǐng)求失敗mcontent = error : + www.error; else /get 請(qǐng)求成功mcontent = www.text; ienumerator gettexture(string picurl) www wwwtexture = new www(picurl); yield return ww

14、wtexture; if (wwwtexture.error != null) /get 請(qǐng)求失敗debug.log(error : + wwwtexture.error); else /get 請(qǐng)求成功mpicture = wwwtexture.texture; string picbyte; ienumerator gettexturebyte(string picurl) www www = new www(picurl); yield return www; if (www.error != null) /get 請(qǐng)求失敗debug.log(error : + www.error);

15、else /get 請(qǐng)求成功debug.log(picbytes text = + www.text); xmldocument xmldoc = new xmldocument(); xmldoc.load(new stringreader(www.text); /通過(guò)索引查找子節(jié)點(diǎn)picbyte = xmldoc.getelementsbytagname(base64binary).item(0).innertext; testc = picbyte; mpicturebyte = bttetopic(picbyte); /解析 xml string analysisxml() strin

16、g str = ; xmldocument xmldoc = new xmldocument(); xmldoc.load(new stringreader(mcontent); /得到文檔根節(jié)點(diǎn)的所有子節(jié)點(diǎn)集合/xmlnodelist nodes = xmldoc.documentelement.childnodes; /通過(guò)節(jié)點(diǎn)名得到節(jié)點(diǎn)集合x(chóng)mlnodelist nodes = xmldoc.getelementsbytagname(string); /通過(guò)索引查找子節(jié)點(diǎn)str += item1 = + xmldoc.getelementsbytagname(string).item(1

17、).innertext + nn; /遍歷所有子節(jié)點(diǎn)foreach (xmlelement element in nodes) if (element.name = string) str += element.innertext + n; return str; /圖片與 byte 互轉(zhuǎn)public void convertpng(texture2d pic) byte data = pic.encodetopng(); debug.log(data = + data.length + | + data0); mconvertpng = new texture2d(200, 200); mconvertpng.loadimage(data); /byte與 base64 互轉(zhuǎn)texture2d b
