使用RestTemplate调用第三方接口
1.RestTemplate调用第三方接口
需求:根据第三方接口提供的url、参数为String类型的data,请求方式POST,contentType为x-www-form-urlencoded,用restTemplate调用接口返回数据。
2.RestTemplate配置类
package com.xxx.config;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.client.ClientHttpRequestFactory;
import org.springframework.http.client.SimpleClientHttpRequestFactory;
import org.springframework.web.client.RestTemplate;
/**
* @Auther: xxx
* @Date:
* @Description: RestTemplate配置类
*/
@Configuration
public class RestTemplateConfig {
@Bean
public RestTemplate restTemplate(ClientHttpRequestFactory factory) {
return new RestTemplate(factory);
}
@Bean
public ClientHttpRequestFactory simpleClientHttpRequestFactory() {
SimpleClientHttpRequestFactory factory = new SimpleClientHttpRequestFactory();
factory.setReadTimeout(5000);
factory.setConnectTimeout(5000);
return factory;
}
}
3.代码实现
package com.xxx.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.HttpEntity;
import org.springframework.http.HttpHeaders;
import org.springframework.util.LinkedMultiValueMap;
import org.springframework.util.MultiValueMap;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.client.RestTemplate;
@RestController
@RequestMapping("/api/restTemplate")
public class SpringRestTemplateController {
@Autowired
private RestTemplate restTemplate;
/**
*
* @return
*/
@PostMapping(value = "/testPostApi")
public Object testPost() {
MultiValueMap<String, Object> postParameters = new LinkedMultiValueMap<>();
postParameters.add("data", "你的参数");
HttpHeaders headers = new HttpHeaders();
headers.add("Content-Type", "application/x-www-form-urlencoded");
HttpEntity<MultiValueMap<String, Object>> r = new HttpEntity<>(postParameters, headers);
return restTemplate.postForObject("你的url", r, String.class);
}
}
4.使用postman测试接口
得到第三方接口指定返回类型的数据
