Alamofire 使用通用键和多个值传递参数? [英] Alamofire Passing Parameter With Common Keys and Multiple Values?

问题描述

我需要在我的项目中这样做:

如果我在 Alamofire 中手动将字符串附加到我的 URL，我可以轻松地做到这一点，但我不想要那样.我希望参数作为 Parameter 对象.

参数的一个公用键中的多个值

我一直在做什么:

public func findCreate(tags: [String], withBlock completion: @escaping FindCreateServiceCallBack) {/* http://baseurlsample.com/v1/categories/create_multiple?category_name[]=fff&category_name[]=sss */让 findCreateEndpoint = CoreService.Endpoint.FindMultipleCategories让参数:参数 = [category_name[]""；: 标签]Alamofire.request(找到创建端点，方法:.post，参数:参数，编码:URLEncoding(目的地:.queryString)，标头:无).responseJSON {(响应)中打印(响应)}//....}

如果我运行它，当前结果是可以的，但是发送到服务器的值有 [";"].例如:

[巧克力"]

再次，问题是，我整个代码的哪一部分是错误的?如何发送具有一个公共键和多个值的上述参数?

我也尝试将 encoding 选项添加到 Alamofire.request() 如果我添加 encoding: JSONEncoding.prettyPrinted 或 编码:JSONEncoding.default 我得到状态码 500.

一些具有相同问题但没有确切答案的链接，我总是看到有使用自定义编码等答案的帖子，仅此而已.

• https://github.com/Alamofire/Alamofire/issues/570

• Moya/Alamofire - 具有相同密钥的 URL 编码参数

附加信息:

这有效，但我需要发送多个字符串:

let 参数:[String : Any] = [category_name[]";:标签.首先！]

这也有效:

Alamofire.request("http://baseurlsample.com/v1/categories/create_multiple?category_name[]=fff&category_name[]=sss", method: .post).responseJSON { (data)在打印(数据)}

解决方案

您不需要为此格式自定义编码.

您可以发送这样编码的参数:

category_name[]=rock&category_name[]=paper

通过使用 URLEncoding(您已经在这样做)并在数组中包含应该具有相同键的多个值:

let 参数:Parameters = ["category_name": ["rock", "paper"]]

它会在category_name之后为你添加[]，所以当你声明参数时不要包含它.>

I need to do this in my project:

I can do this easily if I manually append strings to my URL in Alamofire, but I don't want that. I want the parameters as Parameter object.

multiple values in one common key for parameter

What I've been doing:

public func findCreate(tags: [String], withBlock completion: @escaping FindCreateServiceCallBack) {
    
    /* http://baseurlsample.com/v1/categories/create_multiple?category_name[]=fff&category_name[]=sss */
    
    let findCreateEndpoint = CoreService.Endpoint.FindMultipleCategories
    
    let parameters: Parameters = ["category_name[]" : tags]
    
    Alamofire.request(
        findCreateEndpoint,
        method: .post,
        parameters: parameters,
        encoding: URLEncoding(destination: .queryString),
        headers: nil
        ).responseJSON { (response) in
            print(response)
    }
//....
}

The current result if I run this is okay but the values sent to the server has [" "]. For example:

["chocolate"]

Again, the questions are, in which part of my whole code I'm wrong? How can I send parameters like the above that have one common key and multiple values?

I also have tried adding encoding option to the Alamofire.request() If I add encoding: JSONEncoding.prettyPrinted or encoding: JSONEncoding.default I get status code 500.

Some links that have the same question but no exact answers, I always see posts that have answers like using a custom encoding and that's it.

• https://github.com/Alamofire/Alamofire/issues/570

• Moya/Alamofire - URL encoded params with same keys

Additional info:

This works, but I need to send multiple String:

let parameters: [String : Any] = ["category_name[]" : tags.first!]

And this works as well:

Alamofire.request("http://baseurlsample.com/v1/categories/create_multiple?category_name[]=fff&category_name[]=sss", method: .post).responseJSON { (data) in
    print(data)
}

解决方案

You don't need a custom encoding for this format.

You can send parameters encoded like this:

category_name[]=rock&category_name[]=paper

By using URLEncoding (which you're already doing) and including the multiple values that should have the same key in an array:

let parameters: Parameters = ["category_name": ["rock", "paper"]]

It'll add the [] after category_name for you, so don't include it when you declare the parameters.
