如何在 Android 中的改造响应中添加多个标头

Question

在我的应用程序中，我想从服务器获取一些数据，为此我使用了改造。
我应该添加一些标题，但运行应用程序后显示ForceClose错误！

Api服务代码：

interface ApiServices {
    @Headers(
        "Accept: application/json",
        "Content-Type : application/json"
    )
    @POST("user/get-password")
    fun sendPhoneNumber(@Body body: LoginSendPhoneBody): Single<Response<LoginSendPhoneResponse>>

    @Headers(
        "Accept: application/json",
        "Content-Type : application/json"
    )
    @POST("addresses")
    fun newAddress(@Header("Authorization") userToken: String, @Body body: NewAddressBody):
            Single<Response<NewAddressResponse>>
}

我的Retrofit版本是2.5.0！

在改造文档中，我阅读了设置多个标头的内容，我应该将其用于{}标头，例如@Headers({...})，但添加后{}显示错误，我无法使用{}！

日志猫错误：

java.lang.IllegalArgumentException: Unexpected char 0x20 at 12 in header name: Content-Type 
    at okhttp3.Headers.checkName(Headers.java:261)
    at okhttp3.Headers$Builder.add(Headers.java:311)

    at $Proxy2.sendPhoneNumber(Unknown Source)
    at com.app.app.data.network.ApiUseCase.getSendPhoneNumber(ApiUseCase.kt:42)

我该如何修复它？

Answer 1

改变

"Content-Type : application/json"

到

"Content-Type: application/json"

只需删除后面的空白即可Content-Type:)

Answer 2

您可以使用 HeaderMap，同样

val header = HashMap<String, String>()
    header["Accept"] = "application/json"
    header["Content-Type"] = "application/json"
    header["Authorization"] = "userToken"



@POST("addresses")
    fun newAddress(@HeaderMap headers: Map<String, String>, @Body body: NewAddressBody): Single<Response<NewAddressResponse>>

Answer 3

在 Kotlin API 接口中：

 @Headers(
        "Accept: application/json",
        "User-Agent : PostmanRuntime/7.29.0",
        "Accept : */*",
        "Accept-Encoding : gzip, deflate, br",
        "Connection : keep-alive"
    )
