iOS 和 H5 页面交互（WKWebview 和 UIWebview cookie 设置）

主要记录关于cookie相关的坑

1. uiwebview

1. uiwebview 相对比较简单直接通过 nshttpcookiestorage 设置cookie就能实现。

代码部分

```
  nsurl *cookiehost = [nsurl urlwithstring:self.domain];
// 设定 cookie
nshttpcookie *cookie = [nshttpcookie cookiewithproperties:
                        [nsdictionary dictionarywithobjectsandkeys:
                         [cookiehost host], nshttpcookiedomain,
                         [cookiehost path], nshttpcookiepath,
                         self.cookiekey,  nshttpcookiename,
                         self.cookievalue, nshttpcookievalue,
                         nil]];
// 加入cookie
[[nshttpcookiestorage sharedhttpcookiestorage] setcookie:cookie];
```

2. 如果在第一次请求的时候需要在httprequest 通过setvalueforkey设置 headervalue

2. wkwebview

在使用wkwebview的时候也是需要分两种情况传递：

1.httprequest 请求url的时候携带如后端php获取 cookie
2.注入js 目的是让前端从页面里边获取到cookie 可以通过在document.cookie 设置通过wkwebview 初始化时候把js传递过去

`wkuserscript * cookiescript = [[wkuserscript alloc] initwithsource: cookievalue injectiontime:wkuserscriptinjectiontimeatdocumentstart formainframeonly:no];
3.nshttpcookiestorage 似乎不携带没问题，因为我们目前没有通过这个传递cookie

网上参考别人的方法是要实现下面几个步骤，但是我们项目并没有按照这三种必要方式，但是可以做个参考：

wkwebview三个处理步骤：（1）ios11，wkhttpcookiestore 直接传递。（如果是只支持ios11，下面两步可以不做）；（2）ios8-ios10， js注入；（3）php携带cookie方式

#pragma mark - wkwebview
// ios11

    nsurl *cookiehost = [nsurl urlwithstring:self.domain];
    // 设定 cookie
    nshttpcookie *cookie = [nshttpcookie cookiewithproperties:
                            [nsdictionary dictionarywithobjectsandkeys:
                             [cookiehost host], nshttpcookiedomain,
                             [cookiehost path], nshttpcookiepath,
                             self.cookiekey,  nshttpcookiename,
                             self.cookievalue, nshttpcookievalue,
                             //                             [nsdate datewithtimeintervalsincenow:30*60*60],nshttpcookieexpires,
                             nil]];
    
    // 加入cookie
    //发送请求前插入cookie；
    if (@available(ios 11.0, *)) {
        wkhttpcookiestore *cookiestore = wkwebview.configuration.websitedatastore.httpcookiestore;
        [cookiestore setcookie:cookie completionhandler:^{
            
            comple?comple():nil;
        }];
    } else {
        
        
    }

}

// js携带cookie的形式
- (void)setwkjscookie:(wkusercontentcontroller *)usercontentcontroller {
    // 单个cookie，多个的话，再加上document.cookie ='%@=%@';一次
    nsstring *cookiestr = [nsstring stringwithformat:@"document.cookie ='%@=%@';",self.cookiekey,self.cookievalue];
    wkuserscript * cookiescript = [[wkuserscript alloc] initwithsource: cookiestr injectiontime:wkuserscriptinjectiontimeatdocumentstart formainframeonly:no];
    [usercontentcontroller adduserscript:cookiescript];
}

// php携带cookie的形式
- (void)setwkphpcookie:(nsmutableurlrequest *)request {
    //通过host关联cookie。
    nsmutabledictionary *cookiedic = [nsmutabledictionary dictionary];
    nsmutablestring *cookievalue = [nsmutablestring stringwithformat:@""];
    nshttpcookiestorage *cookiestorage = [nshttpcookiestorage sharedhttpcookiestorage];
    for (nshttpcookie *cookie in [cookiestorage cookies]) {
        [cookiedic setobject:cookie.value forkey:cookie.name];
    }
    if ([cookiedic objectforkey:[cookiemanager shareinstance].cookiekey]) {
        [cookiedic removeobjectforkey:[cookiemanager shareinstance].cookiekey];
    }
    
    // cookie重复，先放到字典进行去重，再进行拼接
    for (nsstring *key in cookiedic) {
        nsstring *appendstring = [nsstring stringwithformat:@"%@=%@;", key, [cookiedic valueforkey:key]];
        [cookievalue appendstring:appendstring];
    }
    
    [cookievalue appendstring:[nsstring stringwithformat:@"%@ = %@;",self.cookiekey,self.cookievalue]];
    [request addvalue:cookievalue forhttpheaderfield:@"cookie"];
}
