我要评论前言
java发送请求的方法有很多，这里只介绍两种。
hutool和resttemplate
下边提供两种后端发送请求的方式，一个是基于hutool工具的，一个是基于resttemplate的，为什么要写这两种呢，因为有的时候用hutool的方式不太管用，有的时候用resttemplate也不太管用，所以就且换着用，谁能用，用谁。
hutool方式
get请求
@getmapping("/userelelist")
@responsebody
public jsonobject userelelist(@requestparam(name = "usercode") string usercode, httpservletrequest request) {
string authorization = request.getheader("authorization");
string token = request.getheader("token");
string body = httputil.createget("http://ip:8068/userelelist?usercode=" + usercode)
.header("authorization", authorization)
.header("token", token)
.execute()
.body();
return jsonobject.parseobject(body);
}
@getmapping("/getkdtoken")
@responsebody
public jsonobject userelelist(@requestparam(name = "appid") string appid,
@requestparam(name = "appsecret") string appsecret,
@requestparam(name = "granttype") string granttype) {
string post = httputil.get("http://ip:8068/getkdtoken?appid=" + appid + "&appsecret=" + appsecret + "&granttype=" + granttype);
return jsonobject.parseobject(post);
}
post请求
@postmapping("/elerechargemoneyalllist")
@responsebody
public jsonobject elerechargemoneyalllist(@requestbody map<string, object> map, httpservletrequest request) {
string authorization = request.getheader("authorization");
string token = request.getheader("token");
object elemeterid = map.get("elemeterid");
object money = map.get("money");
object selorderno = map.get("selorderno");
string post = httputil
.createpost("http://ip:8068/elerechargemoneyalllist?elemeterid=" + elemeterid + "&money=" + money + "&adds=0&selorderno=" + selorderno + "&paytype=40")
.header("authorization", authorization)
.header("token", token)
.execute()
.body();
return jsonobject.parseobject(post);
}
@postmapping("/getclientbycnumber")
@responsebody
public jsonobject getclientbycnumber(@requestbody map<string, object> map) {
string post = httputil.post("http://ip:8006/getclientbycnumber", map);
return jsonobject.parseobject(post);
}
resttemplate方式
@postmapping("/userpricepay")
@responsebody
public jsonobject userpricepay(@requestbody map<string, object> map, httpservletrequest request) {
string sign = request.getheader("sign");
resttemplate resttemplate = new resttemplate();
// 设置请求头，指定content-type为application/json
httpheaders headers = new httpheaders();
headers.setcontenttype(mediatype.application_json);
// headers.setcontenttype(mediatype.application_json_utf8);
headers.set("sign", sign);
// 将解析后的 json 对象转换为 multivaluemap
httpentity<map<string, object>> requestentity = new httpentity<>(map, headers);
responseentity<string> exchange = resttemplate.exchange("https://ip:8080/userpricepay", httpmethod.post, requestentity, string.class);
return jsonobject.parseobject(exchange.getbody());
