以下是我所拥有代码的摘录。
fullsrcurl = self.srcjson + format_type + '&jobname=' + joburl
srcfile = urllib2.urlopen(fullsrcurl)
if self.format_export == 'json':
srcdata = json.load(srcfile)
pprint(srcdata)
srcjobmst_id = srcdata["jobmst_id"][0]
我尝试使用上述代码的内容是从API网址中读取的，该网址会返回json并获取＆＃39; jobmst_id＆＃39;来自那个json的价值。 pprint（srcdata在下面提供了json）我想从中拉出jobmst_id值，在下面的例子中将是＆＃39; 58908＆＃39;。我很乐意将它作为一个可以转换的整数，但是就目前看来它在主题上的错误就失败了。
以下是json -

答案 0 :(得分：1)
检索数据的方法是srcdata[0]["jobmst_id"]而不是srcdata["jobmst_id"][0]。
