改造 2 - POST 请求变成了 GET? [英] Retrofit 2 - POST request became GET?

问题描述

我的 POST 请求不断发送为 GET &被 API 端点拒绝

My POST request keeps sending as GET & got rejected by API endpoint

MyService 类

@FormUrlEncoded
@POST("api/users/")
Call<List<User>> getUsers(@FieldMap HashMap<String, String> parameters);

请求代码

Gson builder = new GsonBuilder().setLenient().create();
Retrofit client = new Retrofit.Builder()
        .baseUrl(Constants.API_ENDPOINT_TEST_URL)
        .addConverterFactory(GsonConverterFactory.create(builder))
        .build();
mApiService = client.create(MyService.class);
Call<List<User>> call = mApiService.getUsers(mParameters);
call.enqueue(new Callback<List<User>>() {
    @Override
    public void onResponse(Call<List<User>> call, Response<List<User>> response) {
        mResponse = response.body();
        mResponseObserver.onFinish(mResponse);
    }

    @Override
    public void onFailure(Call<List<User>> call, Throwable t) {
        mResponseObserver.onFailure();
    }
});

但是当它以 GET 请求形式到达服务器时，服务器拒绝了它！?用调试器检查后，我看到:

But server rejects it as it reached the server in GET request form !? Having checked with debugger, I saw that:

rawResponse.request.method = GET

这是显示改造请求对象的监视窗口的屏幕截图:

Here is screenshot of watch window showing the retrofit's request object:

如您所见，请求方法是 GET.但奇怪的部分是在 tag 中，它显示了一个带有 POST 方法的请求对象?

As you can see, the request method was GET. But the weird part is in the tag, it shows a request object with POST method?

我错过了什么吗?

更新

我添加了日志拦截器 &这是日志:

I added logging interceptor & here is the log:

D/OkHttp: --> POST http://***/api/users/ http/1.1
D/OkHttp: Content-Type: application/x-www-form-urlencoded
D/OkHttp: Content-Length: 56
D/OkHttp: --> END POST
D/OkHttp: <-- 200 OK https://***/api/users/ (388ms)
D/OkHttp: Date: Thu, 01 Sep 2016 11:50:23 GMT
D/OkHttp: Server: Apache
D/OkHttp: X-Powered-By: PHP/5.4.34
D/OkHttp: Cache-Control: max-age=2592000
D/OkHttp: Expires: Sat, 01 Oct 2016 11:50:23 GMT
D/OkHttp: Vary: Accept-Encoding
D/OkHttp: Content-Type: application/json; charset=UTF-8
D/OkHttp: Set-Cookie: SESSION_DEFAULT=***; expires=Sun, 04-Sep-2016 11:50:24 GMT; path=/; HttpOnly
D/OkHttp: Set-Cookie: COOKIE[***]=***; path=/; httponly
D/OkHttp: Connection: close
D/OkHttp: <-- END HTTP

看起来请求是一个POST.但是，服务器仍然以错误消息响应，说请求方法是 GET

looks like the request is a POST. But, the server still responds with error message, saying that the request method is a GET

嗯，我会深入研究一下.

Hmm, I'll dig a little bit more into it.

推荐答案

其实问题在于两个因素的结合:

Actually, the issue is the combination of 2 factors:

1. 发出了错误的请求协议(http 而不是 https)
2. 服务器回复了一条关于错误协议的奇怪消息:不支持 GET".

无论如何，感谢@nshmura 的帮助.
