改造 - @Body 参数不能与表单或多部分编码一起使用 [英] Retrofit - @Body parameters cannot be used with form or multi-part encoding

问题描述

我正在尝试发出一个请求，其中我想包含一个 Header 、一个 form-urlencoded 字段和一个 json 正文.我的改造界面如下

I m trying to make a request in which I want to include a Header , a form-urlencoded field and a json body. My Retrofit interface is as follows

@FormUrlEncoded
@POST("/api/register")
Observable<RegisterResponse> register(
    @Header("Authorization") String authorization, 
    @Field("grant_type") String grantType, 
    @Body RegisterBody body
);

当我发出此请求时，我返回异常@Body 参数不能与表单或多部分编码一起使用.
我也尝试过使用 @Multipart 注释:

When I make this request I get back exception @Body parameters cannot be used with form or multi-part encoding.
I have also tried with the @Multipart annotation:

@Multipart
@FormUrlEncoded
@POST("/api/register")
Observable<RegisterResponse> register(
    @Header("Authorization") String authorization, 
    @Part("grant_type") TypedString grantType, 
    @Body RegisterBody body
);

并且我得到一个 IllegalArgumentException 并且只允许一个编码注释.

and I get an IllegalArgumentException and only one encoding annotation is allowed.

推荐答案

这篇文章为我指明了正确的方向 https://stackoverflow.com/a/21423093/1446856.我附加了正文中的所有内容并将其作为 TypedInput 发送.
所以界面看起来像这样

This post pointed me to the right direction https://stackoverflow.com/a/21423093/1446856. I attached everything in the body and send it as a TypedInput.
So the interface looks something like this

@POST("/api/register")
@Headers({ "Content-Type: application/json;charset=UTF-8"})
Observable<RegisterResponse> register(
    @Header("Authorization") String authorization,
    @Body TypedInput body
);

身体看起来像这样

String bodyString = jsonBody + "?grant_type=" + 
    grantType + "&scope=" + scope;
TypedInput requestBody = new TypedByteArray(
    "application/json", bodyString.getBytes(Charset.forName("UTF-8")));
