Question

这让我发疯，感谢您的帮助。这是我想要做的：

使用JSON文件作为输入，找到两个连续的行，如下所示：

{
     "description"

然后，如果找到该条件，请在此点上方插入其他JSON。遵循代码几乎的方法除了出于某种原因，我出于某种原因无法理解，因此跳过了一行。

代码：

with open('file.in',encoding="utf8") as in_file:
    with open('file.out','w',encoding="utf8") as out_file:

        tag_to_check_line1 = '{'
        tag_to_check_line2 = '"description"'
        tag_to_check_not_line2 = ',"description"'
        irofile = iter(in_file)
        for line in irofile:
            if tag_to_check_line1 in line:
                out_file.write(line)
                line = next(irofile)
                if tag_to_check_line2 in line and tag_to_check_not_line2 not in line:
                    out_file.write('\n')
                    out_file.write('"fields": {\n')
                    out_file.write('"project":\n')
                    out_file.write('{\n')
                    out_file.write('"key": "GID"\n')
                    out_file.write('},\n')
                    out_file.write(line)
            else:
                out_file.write(line)

输入数据如下：

 {
        "description": "<p>The description is here.</p>",
        "customfield_16818": "REQ-7591",
        "customfield_16819": "GID-1214020",
        "customfield_16815":{"self":"https://jira.com/rest/api/2/customFieldOption/20685","value":"No","id":"20685"},
        "summary": "MySQL Redundancy",
        "customfield_16816": "0",
        "customfield_16817": "0",
        "tag": "tagtext"
    }

除了缺少"summary"标签之外，结果输出看起来正确：

 {

"fields": {
"project":
{
   "key": "GID"
},
        "description": "<p>The description is here.</p>",
        "customfield_16818": "REQ-7591",
        "customfield_16819": "GID-1214020",
        "customfield_16815":{"self":"https://jira.com/rest/api/2/customFieldOption/20685","value":"No","id":"20685"},
        "customfield_16816": "0",
        "customfield_16817": "0",
        "tag": "tagtext"
    }

所以问题是：为什么缺少"summary"标签？

您缺少else:子句。可以如下所示进行固定：

with open('file.in',encoding="utf8") as in_file:
    with open('file.out', 'w', encoding="utf8") as out_file:
        tag_to_check_line1 = '{'
        tag_to_check_line2 = '"description"'
        tag_to_check_not_line2 = ',"description"'
        irofile = iter(in_file)
        for line in irofile:
            if tag_to_check_line1 in line:
                out_file.write(line)
                line = next(irofile)
                if tag_to_check_line2 in line and tag_to_check_not_line2 not in line:
                    out_file.write('\n')
                    out_file.write('"fields": {\n')
                    out_file.write('"project":\n')
                    out_file.write('{\n')
                    out_file.write('"key": "GID"\n')
                    out_file.write('},\n')
                    out_file.write(line)
                else:                           # ADD THESE
                    out_file.write(line)        # TWO LINES
            else:
                out_file.write(line)

通过“ iter”解析文件不包含字符串
