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：using unityengine;using system.collections;using system.collections.generic;using system.xml;using
