ApolloNetworkManager
ApolloNetworkManager 是 Swift 语言的一个 GraphiQL 工具
Graphql
官方文档： https://apollo.graphql.net.cn/docs/ios/installation.html#adding-build-step
中文文档： http://graphql.cn
线上调试：https://www.graphqlbin.com
请先阅读官方的文档
安装
pod ‘ApolloNetworkManager’
使用
调用逻辑
ApolloNetworkManager.shared.apiurl = "https://dev.api.xxxxx.com/graphql" // 自己服务器的端点地址
ApolloNetworkManager.shared.httpHeader = [:] // 自己服务器的httpHeader信息
/*调用完登录接口再去调用第二个接口*/
ApolloNetworkManager.shared.performMutation(mutation: UsersMutation.init(username: "13500000000", password: "123456"), client: StoreManager.shared.apollo){ (result,error) in
if let err = error{
print(err)
}else{
if let data = result?.data?.createUserToken {
UserDefaults.standard.set(data.token, forKey: "token")
UserDefaults.standard.set(data.token, forKey: "studentid")
}
}
}
ApolloNetworkManager.shared.performFetch(fetch: AppSettingQuery(), client: StoreManager.shared.apolloClientWithToken) { (result,error) in
if let err = error{
print(err)
}else{
if let data = result?.data?.appsetting {
print(data.cdnUrl)
}
}
}
写在前面： 项目 项目运行 项目运行不起来 项目运行不起来的 项目运行不起来的， 项目运行不起来的，主要 项目运行不起来的，主要看 项目运行不起来的，主要看逻辑 项目运行不起来的，主要看逻辑， 项目运行不起来的，主要看逻辑，供参考
首先说的是我们项目的大概逻辑，我们这边有两个端点地址，一个是noauth的，一个是auth的，一开始就有两个 scheme.json 文件。
所以我这边设置了两个脚本分别在两个目录里面的 graphql 文件生成对应的 swift 文件
如下两个图所示
