Question

我正在尝试使用以下代码创建对第三方API的请求链：

import Vapor

final class APIController: RouteCollection {

    private let baseULR = "..."

    func boot(router: Router) throws {
        router.post("login", use: validate)
    }

    func validate(_ req: Request) throws -> Future<Response> {
        // Get the phone number of the user
        let phoneNumber = try req.content.syncGet(String.self, at: "phone_number")
        return try req.client().post("\(baseUrl)/...", beforeSend: { post in
            try post.content.encode(json: ["phone_number": phoneNumber])
        })
    }
}

但是在测试请求时，出现错误：

[ ERROR ] Abort.415: Unsupported Media Type (ContentCoders.swift:95)
[ DEBUG ] Suggested fixes for Abort.415: Register an `DataDecoder` using `ContentConfig`. Use one of the decoding methods that accepts a custom decoder. (ErrorMiddleware.swift:26)

不幸的是，我不知道如何解决。

Answer 1

您可以尝试提供Content-Type的有效载荷

func validate(_ req: Request) throws -> Future<Response> {
    // Get the phone number of the user
    return req.content.get(String.self, at: "phone_number").flatMap { phoneNumber in
        return try req.client().post("/...") {
            try $0.content.encode(["phone_number": phoneNumber], as: .json)
        }
    }
}

蒸气3：

向public func configure(_ config: inout Config, _ env: inout Environment, _ services: inout Services) throws文件中的configure.swift函数添加代码

var contentConfig = ContentConfig()
//same to request content-type
contentConfig.use(decoder: URLEncodedFormDecoder(), for: .urlEncodedForm)
services.register(contentConfig)

访问`Request`主体参数
