使用AFNetworking框架传x-www-form-urlencode数据服务器一直返回参数不存在的错误。

let manager = AFHTTPSessionManager()
manager.requestSerializer = AFHTTPRequestSerializer()
manager.requestSerializer.setValue(token, forHTTPHeaderField: "Authorization")
manager.requestSerializer.setValue("5", forHTTPHeaderField: "beId")
manager.requestSerializer.setValue("application/x-www-form-urlencode", forHTTPHeaderField: "Content-Type")
manager.post(url, parameters: dict, progress: nil, success: { task, responseObject in

    if let anObject = responseObject {
        print("上传成功 === \(anObject)")
    }
}, failure: { task, error in
    print("上传错误 == error == \(error)")
})

看了这篇https://stackoverflow.com/questions/35239506/afnetworking-3-x-www-form-urlencoded-post-data才找到解决的办法。

对比之后发现他没加manager.requestSerializer.setValue("application/x-www-form-urlencode", forHTTPHeaderField: "Content-Type")这句代码，试着去掉果然能正常返回。
修改后完整代码：

let manager = AFHTTPSessionManager()
manager.requestSerializer = AFHTTPRequestSerializer()
manager.requestSerializer.setValue(token, forHTTPHeaderField: "Authorization")
manager.requestSerializer.setValue("5", forHTTPHeaderField: "beId")
//        manager.requestSerializer.setValue("application/x-www-form-urlencode", forHTTPHeaderField: "Content-Type")
manager.post(url, parameters: dict, progress: nil, success: { task, responseObject in

    if let anObject = responseObject {
        print("上传成功 === \(anObject)")
    }
}, failure: { task, error in
    print("上传错误 == error == \(error)")
})

想要post x-www-form-urlencode数据反而不能加请求头声明Content-Type为x-www-form-urlencode。
