這篇文章主要講解了“Java后端怎么實(shí)現(xiàn)微信小程序校驗(yàn)信息”，文中的講解內(nèi)容簡單清晰，易于學(xué)習(xí)與理解，下面請大家跟著小編的思路慢慢深入，一起來研究和學(xué)習(xí)“Java后端怎么實(shí)現(xiàn)微信小程序校驗(yàn)信息”吧！
前端只需要將圖片和內(nèi)容傳過來即可
HttpClient的依賴和json轉(zhuǎn)換的依賴
<dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>1.2.54</version> </dependency> <dependency> <groupId>org.apache.httpcomponents</groupId> <artifactId>httpclient</artifactId> <version>4.5.10</version> </dependency>
用于獲取到access_token后進(jìn)行轉(zhuǎn)換，access_token是什么就不用我多說了吧
