本文探讨了在使用RESTful API时遇到的问题，即在调用GET方法时，URL中的参数未被正确替换。通过分析`restTemplate.exchange()`方法的执行流程，指出在`URIexpanded=this.getUriTemplateHandler().expand(url,uriVariables);`这一步，URL中的`{appId}

GET

ResponseEntity<XimoApiResult<TokenResult>> responseEntity = restTemplate.exchange(url, HttpMethod.GET, null, reference, baseRequest.getAppId(), baseRequest.getAppSecret());

执行进入execute方法后，

public <T> T execute(String url, HttpMethod method, @Nullable RequestCallback requestCallback, @Nullable ResponseExtractor<T> responseExtractor, Object... uriVariables) throws RestClientException {
    URI expanded = this.getUriTemplateHandler().expand(url, uriVariables);
    return this.doExecute(expanded, method, requestCallback, responseExtractor);
}

执行完URI expanded = this.getUriTemplateHandler().expand(url, uriVariables); url参数没有被替换

如:https://xxxx.com/app/extapi/getAccessToken?appId={}

此时需要注意应该将url改为：

https://xxxx.com/app/extapi/getAccessToken?appId={appId}
