我有以下http帖子正文通过chargify的web钩子发送到asp.net web api。
id=38347752&event=customer_update&payload[customer][address]=qreweqwrerwq&payload[customer][address_2]=qwerewrqew&payload[customer][city]=ererwqqerw&payload[customer][country]=GB&payload[customer][created_at]=2015-05-14%2004%3A46%3A48%20-0400&payload[customer][email]=a%40test.com&payload[customer][first_name]=Al&payload[customer][id]=8619620&payload[customer][last_name]=Test&payload[customer][organization]=&payload[customer][phone]=01&payload[customer][portal_customer_created_at]=2015-05-14%2004%3A46%3A49%20-0400&payload[customer][portal_invite_last_accepted_at]=&payload[customer][portal_invite_last_sent_at]=2015-05-14%2004%3A46%3A49%20-0400&payload[customer][reference]=&payload[customer][state]=&payload[customer][updated_at]=2015-05-14%2011%3A25%3A19%20-0400&payload[customer][verified]=false&payload[customer][zip]=&payload[site][id]=26911&payload[site][subdomain]=testsubdomain
如何使用c＃将此有效负载[customer] [address] = value等转换为json字符串？
答案 0 :(得分：0)
你当前的问题
如何使用c＃将chargify webhooks转换为json？
可以推广到
如何从字符串中提取键值对，将它们转换为相应的层次结构并以JSON格式返回？
回答你的问题：
string rawData = "id=38347752&event=customer_update&payload[customer][address]=qreweqwrerwq&payload[customer][address_2]=qwerewrqew&payload[customer][city]=ererwqqerw&payload[customer][country]=GB&payload[customer][created_at]=2015-05-14%2004%3A46%3A48%20-0400&payload[customer][email]=a%40test.com&payload[customer][first_name]=Al&payload[customer][id]=8619620&payload[customer][last_name]=Test&payload[customer][organization]=&payload[customer][phone]=01&payload[customer][portal_customer_created_at]=2015-05-14%2004%3A46%3A49%20-0400&payload[customer][portal_invite_last_accepted_at]=&payload[customer][portal_invite_last_sent_at]=2015-05-14%2004%3A46%3A49%20-0400&payload[customer][reference]=&payload[customer][state]=&payload[customer][updated_at]=2015-05-14%2011%3A25%3A19%20-0400&payload[customer][verified]=false&payload[customer][zip]=&payload[site][id]=26911&payload[site][subdomain]=testsubdomain";
ChargifyWebHook webHook = new ChargifyWebHook(rawData);
JSONNode node = new JSONNode("RootOrWhatEver");
foreach (KeyValuePair<string, string> keyValuePair in webHook.KeyValuePairs)
{
node.InsertInHierarchy(ChargifyWebHook.ExtractHierarchyFromKey(keyValuePair.Key), keyValuePair.Value);
}
string result = node.ToJSONObject();
使用指定的输入，结果如下所示（没有换行符）：

"event": "customer_update",
"payload": {
"customer": {
"address": "qreweqwrerwq",

由于您的问题不仅限于1,2或3级，您显然需要递归解决方案。因此，我创建了一个JSONNode类，它可以通过将层次结构指定为List<string>来插入子项。
如果以A.B.C为例，在开始时方法InsertIntoHierarchy检查是否需要更多级别（取决于指定条目的长度，在我们的例子中，我们将得到一个包含A，B和C的列表，如果是这样，它会插入一个具有指定name级别的子项（用作容器）并将问题传递给此儿童。当然，在该步骤中删除了当前递归级别的名称，因此根据我们的示例，将添加包含name A的容器，并且列表包含B和{{1会被传递给这个容器。如果达到最后一级递归，将插入包含C和name的节点。
要使解决方案正常运行，您需要以下两个类：
