Question

我已成功拦截IIS7 / ASP.NET应用程序中的HTTP Web请求并使用HttpModule我检测到内容类型为“application / json charset = UTF-8”。

我使用Proxy tool来确定JSON内容的样子。

我正在使用HttpModule拦截此Web请求，我想修改JSON内容。

我的问题是：如何将JSON内容提取到JSON对象中，修改它，并使用我的更改更新原始Web请求？

例如，假设JSON内容类似于

{
    "glossary": {
        "title": "example glossary",
        "GlossDiv": {
            "title": "S",
            "GlossList": {
                "GlossEntry": {
                    "ID": "SGML",
                    "SortAs": "SGML",
                    "GlossTerm": "Standard Generalized Markup Language",
                    "Acronym": "SGML",
                    "Abbrev": "ISO 8879:1986",
                    "GlossDef": {
                        "para": "A meta-markup language, used to create markup languages such as DocBook.",
                        "GlossSeeAlso": ["GML", "XML"]
                    },
                    "GlossSee": "markup"
                }
            }
        }
    }
}

那我想做的是：

{
    "glossary": {
        "title": "example glossary",
        "GlossDiv": {
            "title": "S",
            "GlossList": {
                "GlossEntry": {
                    "ID": "C H A N G E   1",
                    "SortAs": "C H A N G E  2",
                    "GlossTerm": "Standard Generalized Markup Language",
                    "Acronym": "SGML",
                    "Abbrev": "ISO 8879:1986",
                    "GlossDef": {
                        "para": "A meta-markup language, used to create markup languages such as DocBook.",
                        "GlossSeeAlso": ["AAA", "BBB", "CCC"]
                    },
                    "GlossSee": "markup"
                }
            }
        }
    }
}

我正在使用C＃代码来实现HttpModule。

使用Newtonsoft.Json可以执行此操作：

dynamic json = JObject.Parse("{'glossary':{'title':'example glossary','GlossDiv':{'title':'S','GlossList':{'GlossEntry':{'ID':'C H A N G E   1','SortAs':'C H A N G E  2','GlossTerm':'Standard Generalized Markup Language','Acronym':'SGML','Abbrev':'ISO 8879:1986','GlossDef':{'para':'A meta-markup language, used to create markup languages such as DocBook.','GlossSeeAlso':['AAA','BBB','CCC']},'GlossSee':'markup'}}}}}");

json.glossary.GlossDiv.GlossList.GlossEntry.ID = 1234;
json.glossary.GlossDiv.GlossList.GlossEntry.SortAs = "abcde";

string result = json.ToString();

如何在C＃中修改JSON内容？
