java - 如何获取此 GET 请求的 json 正文？

Question

我正在使用 Dank Memer imgen api 来操作图像。为了执行 GET 请求，我使用了 Unirest-Java。 (https://kong.github.io/unirest-java/)

代码如下所示:

HttpResponse<JsonNode> response = Unirest.get("https://dankmemer.services/api/changemymind")
                  .header("Authorization", "tokenhere")
                  .queryString("text", "I am a human")
                  .asJson();

如果我使用 response.getHeaders() 请求 header ，它将返回:

但是我需要获取响应正文，当我请求它时它会返回 null。

response.getBody();

// returns null.
// Also returns null when i put:  response.getBody.toString();

如何显示正文？

Answer 1

我尝试将响应作为文件获取并存储它。这非常有效。

HttpResponse<File> response = Unirest.get("https://dankmemer.services/api/changemymind")
                  .header("Authorization", "tokenhere")
                  .queryString("text", "i am a human" )
                  .asFile("C:\\Users\\PC\\Some Folder\\changemymind.jpg");
