我可以使用json dict而不是json数组获取特定对象

Question

这个json文件：

Dictionary<string,string> tableData = new Dictionary<string, string>();
var trNodes = eachNode.FindElements(By.TagName("tr"));

foreach (var trNode in trNodes)
{
    var name = trNode.FindElement(By.CssSelector(".name")).Text.Trim();
    var value = trNode.FindElement(By.CssSelector(".value")).Text.Trim();

    tableData.Add(name,value);
}

var location = tableData["location"];

我如何解析它：

[ {
  "irc_server" : null,
  "ssh_keys" : [ ],
  "branches" : {
    "master" : {
      "running_builds" : [ ],
      "recent_builds" : [ {
        "outcome" : "no_tests",
        "status" : "no_tests",
        "build_num" : 1,
        "vcs_revision" : "748f8679cfc850582e3ada08210d8566a291328c",
        "pushed_at" : "2017-07-21T03:39:46.230Z",
        "added_at" : "2017-07-21T03:36:24.657Z"
      } ],
      "last_non_success" : {
        "outcome" : "no_tests",
        "status" : "no_tests",
        "build_num" : 1,
        "vcs_revision" : "748f8679cfc850582e3ada08210d8566a291328c",
        "pushed_at" : "2017-07-21T03:39:46.230Z",
        "added_at" : "2017-07-21T03:36:24.657Z"
      }
    }
  }]

如何从此数组中获取特定对象？每当我打电话给 projectsurl = get(API_PATH['PROJECTS'].format(self._token)) #get json data from url decodedjson = projectsurl.content.decode('utf-8') #decode to string jsondata = json.loads(decodedjson) #json obj return jsondata['vcs_revision'] 它说我需要一个int而不是一个字符串

您需要执行jsondata[0]['vcs_revision']，因为您的jsondata是一个词典列表。
