如何从 RestTemplate postForLocation 获得 STRING 响应?

问题描述

我正在使用 Spring Framework 中的 RestTemplate 用 Ja​​va 创建一个 REST 客户端.

I'm creating a REST Client in Java with RestTemplate from Spring Framework.

一切都很好，直到我必须用 postForLocation 发帖.

Everything is fine until i have to do a post with postForLocation.

我有权访问的网络服务返回一个 json，其中包含有关 POST ACTION 的信息.

The webservice i'm having access return a json with informations about the POST ACTION.

在 PHP 中很好，但我真的不明白如何在 Java 中使用 RestTemplate.

In PHP it's fine but i really don't understand how to do in Java with RestTemplate.

public String doLogin()
    {
        Map<String, String> args = new HashMap<String, String>();

        args.put("email", AUTH_USER);
        args.put("token", AUTH_PASS);

        String result = restTemplate.postForLocation(API_URL + "account/authenticate/?email={email}&token={token}", String.class, args);

        return result;
    }

这将返回 NULL.

使用相同的代码但使用 getForObject(当然，将 URL 更改为正确的内容)我有一个完整的响应，即这有效:

With same code but using getForObject (and of course, changing the URL to something right) I have a full response, i.e. this works:

String result = restTemplate.getForObject(url, String.class);

那么...如何从 postForLocation 获得 RESPONSE?

So... how get the RESPONSE from a postForLocation?

Obs.:对不起，如果这个问题很愚蠢.我是 Java 初学者

Obs.: Sorry if this question is dumb. I'm beginner in Java

推荐答案

感谢其中一个答案，我找到了如何使用 postForObject 从带有 Spring 的 POST 获取响应

Thanks to one of answers i've figured out how get the response from a POST with Spring by using the postForObject

String result = restTemplate.postForObject(API_URL + "account/authenticate/?email="+ AUTH_USER +"&token="+ AUTH_PASS, null, String.class);

出于某种原因，我不能在 MAP 中使用参数，而必须将它们内嵌在 URL 中.但这对我来说很好.

For some reason i can't use arguments with MAP and have to put them inline in URL. But that's fine for me.
