php小编香蕉为您介绍一种常见问题：无法正确地将表单序列化为json。在开发中，我们经常需要将表单数据以json格式传递给后端处理。然而，有时候我们会遇到一些问题，比如提交的数据无法正确地转换成json格式。这可能是由于表单中包含了特殊字符或格式不正确导致的。在本文中，我们将探讨一些常见的原因和解决方案，帮助您解决这个问题，确保表单数据正确地序列化为json。
问题内容
我正在尝试在 golang 中创建一个 web 应用程序，允许您将收据的详细信息输入到不同的表单中，然后这些表单输入被序列化为 json 对象。但是，我在序列化表单时遇到了麻烦，因为每当我尝试“提交”收据时，都会收到错误消息。
这是 main.go
package mainimport ( "encoding/json" "html/template" "log" "net/http" "strconv" "github.com/gorilla/mux")type item struct { shortdescription string `json:"shortdescription"` price string `json:"price"`}type receipt struct { retailer string `json:"retailer"` purchasedate string `json:"purchasedate"` purchasetime string `json:"purchasetime"` items []item `json:"items"` total string `json:"total"` receiptid int `json:"receiptid"`}var receiptidcounter intvar receipts = make(map[int]receipt)func main() { r := mux.newrouter() r.handlefunc("/", homehandler).methods("get") r.handlefunc("/submit", submithandler).methods("post") r.handlefunc("/receipt/{id}", receipthandler).methods("get") http.handle("/", r) log.fatal(http.listenandserve(":8080", nil))}func homehandler(w http.responsewriter, r *http.request) { t, err := template.parsefiles("templates/home.html") if err != nil { log.println(err) http.error(w, "internal server error", http.statusinternalservererror) return } err = t.execute(w, nil) if err != nil { log.println(err) http.error(w, "internal server error", http.statusinternalservererror) }}func submithandler(w http.responsewriter, r *http.request) { decoder := json.newdecoder(r.body) var receipt receipt err := decoder.decode(&receipt) if err != nil { log.println(err) http.error(w, "bad request", http.statusbadrequest) return } receiptidcounter++ receipt.receiptid = receiptidcounter receipts[receipt.receiptid] = receipt jsonresponse, err := json.marshal(map[string]int{"receiptid": receipt.receiptid}) if err != nil { log.println(err) http.error(w, "internal server error", http.statusinternalservererror) return } w.header().set("content-type", "application/json") w.write(jsonresponse)}func receipthandler(w http.responsewriter, r *http.request) { vars := mux.vars(r) id, err := strconv.atoi(vars["id"]) if err != nil { log.println(err) http.error(w, "bad request", http.statusbadrequest) return } receipt, exists := receipts[id] if !exists { http.notfound(w, r) return } t, err := template.parsefiles("templates/receipt.html") if err != nil { log.println(err) http.error(w, "internal server error", http.statusinternalservererror) return } err = t.execute(w, receipt) if err != nil { log.println(err) http.error(w, "internal server error", http.statusinternalservererror) }}
