Uniapp Spring Boot Data Integration Guide

To achieve data interaction between uniapp and springboot, a front-end and back-end separation approach can be used to transfer data through interfaces.

  1. In Spring Boot, you can create a Controller class, annotate it with @RestController to designate it as a controller, and use @RequestMapping to define the URL path for the interface. Within the interface method, you can use @RequestParam to retrieve parameters passed by uniapp, process the business logic, and return the results back to uniapp.

Example code:

@RestController
@RequestMapping("/api")
public class ApiController {

    @RequestMapping("/getData")
    public String getData(@RequestParam("param") String param) {
        // 处理业务逻辑
        String result = "处理结果";
        return result;
    }
}
  1. In uniapp, you can use methods like uni.request or uni.ajax to send HTTP requests and call springboot interfaces to retrieve data. You can set the URL, request method, parameters, request headers, and other information in the request, and retrieve the data in the success callback function.

Example code:

uni.request({
    url: 'http://localhost:8080/api/getData',
    method: 'GET',
    data: {
        param: '参数值'
    },
    success: function (res) {
        // 获取返回的数据
        console.log(res.data);
    }
});

By following the above steps, data exchange between uniapp and springboot can be realized.
