【问题描述】：

我正在使用 RestAssured 自动化 twitter API

我正在尝试从 twitter API 获取响应：

String responseTweets = given().header("Authorization", "Bearer" +" "+token)
                .queryParam("count", "5")
                .queryParam("screen_name", "twitterapi")
                .when().log().all()
                .get("https://api.twitter.com/1.1/statuses/user_timeline.json").asString();

            117,
            140
          ]
        }
      ]

注意：响应太大，无法在此处打印。如果您注意到它以 Array 开头，我在帖子末尾添加了 treehirarchy img。请参考

当我试图运行下面的代码时。

JsonPath js1 = new JsonPath(responseTweets);
        
        int len = js1.getInt("array.size()");
        System.out.println("Length of the Array " + len);
        
        System.out.println(js1.get("array[0].id"));
    
        
      for(int i=0; i<len; i++)
        {
            System.out.println(js1.get("array["+i+"].text"));
        }

它的显示输出：

Length of the Array 5
null
null
null
null
null
null

能否请您帮助我了解如何从这个 JSON 中获取值。

【解决方案1】：

我使用 JsonPath (com.jayway.jsonpath.JsonPath)。与 JsonPath(io.restassured.path.json.JsonPath) 进行比较非常容易。

List<String> list = JsonPath.read(res, "$[*].text");
System.out.println(list);

//["Today, we\u2019re launching new manage mutes into Twitter API v2.\n\n#TwitterAPI #v2 #EarlyAccess","Today, we announced the release of two new reliability features for the Twitter API v2 streaming endpoints: redunda\u2026 "]
