一，首先介绍一下在mac上用safari调试ios手机的移动端页面
第一步：打开iphone找到以下页面，流程是：【设置】->【Safari】->【高级】->
开启【Web检查器】 ，如图1、图2
第二步：打开Mac上Safari，流程是【选中Safari】->【偏好设置】->【高级】->【在菜单栏中显示“开发”菜单】勾选，如图3，4
第三步：用数据线将iphone和mac连接起来，在手机app上打开一个web网页，在电脑的safari中按照流程执行：【开发】->【手机名称】->【正在调试的网站】如图5，6
第四步：点击上图的192.168.100.116-rechargelist web页面，出来当前页面的资源，时间线，存储空间等。如图5，6
二，正式说今天遇到的问题，方法一json存不进去，方法二可以存进去
方法一：
let data = try JSONSerialization.data(withJSONObject: ["id":GlobalData.shared.logInModel.userId, "phone":GlobalData.shared.logInModel.mobile], options: .prettyPrinted)
let userJson = String(data:data, encoding: .utf8) ?? "{}"
let script = WKUserScript(source:"localStorage.setItem('wrongUserJson','\(userJson)') ;", injectionTime: .atDocumentStart, forMainFrameOnly:false)
configuration.userContentController.addUserScript(script)
userJson = "{\n \"id\" : \"376AA08A44F613A5960BBA9708DE6E057318626B4961F35A6632E2F9140A33E60031043B73978C1344010d16\",\n \"phone\" : \"18616655261\"\n}"
之所以userJson串是这种带\n的格式，是因为JSONSerialization.data(withJSONObject: ["id":GlobalData.shared.logInModel.userId, "phone":GlobalData.shared.logInModel.mobile], options: .prettyPrinted)中的options是NSJSONWritingPrettyPrinted的原因，苹果官网资料是这样说的“为了使打印出来的json串格式标准一些，添加了一些空格和\n符号”,这样的json字符串存不进去cookie和localStroge。
方法二：
let data = try JSONSerialization.data(withJSONObject:["id":GlobalData.shared.logInModel.userId ,"phone":GlobalData.shared.logInModel.mobile], options:JSONSerialization.WritingOptions(rawValue:0))
let userJson = String(data:data, encoding: .utf8) ?? "{}"
let script = WKUserScript(source:"localStorage.setItem('rightUserJson','\(userJson)') ;", injectionTime: .atDocumentStart, forMainFrameOnly:false)
configuration.userContentController.addUserScript(script)
userJson = "{\"id\":\"376AA08A44F613A5960BBA9708DE6E057318626B4961F35A6632E2F9140A33E60031043B73978C1344010d16\",\"phone\":\"18616655261\"}"
这种格式的json字符串能存进去，如下图
fileprivate func creatUserCookie() -> HTTPCookie? {
let data = try JSONSerialization.data(withJSONObject: ["id":GlobalData.shared.logInModel.userId, "phone":GlobalData.shared.logInModel.mobile], options:JSONSerialization.WritingOptions(rawValue:0))
let userJson = String(data: data, encoding: .utf8) ?? "{}"
let properties: [HTTPCookiePropertyKey:Any] = [
HTTPCookiePropertyKey.name: "rightUserJson",
HTTPCookiePropertyKey.value: userJson,
HTTPCookiePropertyKey.domain: "https://www.baidu.com",
HTTPCookiePropertyKey.path: "/"
]
returnHTTPCookie(properties: properties)
}
if let userCookie = creatUserCookie(), let cookieStr = HTTPCookie.requestHeaderFields(with: [userCookie])["Cookie"] {
// 设置页面请求的cookie
request.addValue(cookieStr, forHTTPHeaderField:"Cookie")
let cookieScript = WKUserScript(source:"document.cookie = '\(cookieStr)' ;", injectionTime: .atDocumentStart, forMainFrameOnly:false)
configuration.userContentController.addUserScript(cookieScript)
}
json字符串存cookie,也成功存进去，如下图
写得比较匆忙，如有错误请指正，谢谢。
