发送http和https请求工具类 Json封装数据

在一些业务中我们可要调其他的接口(第三方的接口) 这样就用到我接下来用到的工具类。
用这个类需要引一下jar包的坐标

       <dependency><groupId>org.jsoup</groupId><artifactId>jsoup</artifactId><version>1.11.3</version></dependency>

引好坐标后就可以使用这个工具类了；

Connection.Response post = HttpUtils.post("http://localhost:10090/Controller/httpToJson",str);
String body = post.body();
System.out.println("响应报文:"+body);

str代表你需要传的参数一般是json类型的数据

访问成功后一般会返回你一个json的数据，但是这个数据有一些问题，它会进行转译。我把这个字符串进行了一些处理。

{"result":"{\"FoodID\":\"A66J54DW9IKJ75U3\",\"FoodName\":\"桃子\",\"FoodBrand\":\"龙冠\",\"FoodPlace\":\"吉林\",\"FoodText\":\"四打击我家的娃哦哦囧\",\"FoodImg\":\"sdasdasdasd\",\"FoodProInfo\":[{\"ProjectName\":\"浇水\",\"UserName\":\"周锐\",\"OperationDescribe\":\"给桃子树浇水茁壮成长\",\"ImgUrl\":\"asdlpalplpd23\",\"OperationTm\":\"20200616103856\"}],\"FoodPackInfo\":null,\"FoodDetectionInfo\":null,\"FoodLogInfo\":null}","code":0,"message":"查询智能合约成功"}

对这个串进行替换等一些操作，然后把它转成json对象。通过json工具类把它自动封装到实体类型中，
（在进行封装实体的时候一定要注意，json串的属性和实体的属性要完全相同）否则会报错的（避免入坑）

 Connection.Response post = HttpUtils.post("http://localhost:10090/fabricController/queryChaincode",str);String body = post.body();String replace = body.replace("\\\"", "\"");String replace1 = replace.replace(":\"{", ":{");String replace2 = replace1.replace("}\",", "},");String replace3 = replace2.replace("{\"result\":", "");String replace4 = replace3.replace(",\"code\":0,\"message\":\"查询智能合约成功\"}", "");            com.alibaba.fastjson.JSONObject jsonObject = com.alibaba.fastjson.JSONObject.parseObject(replace4);FoodAllInfo foodAllInfo = JSON.parseObject(replace4, FoodAllInfo.class);
