Question

null

呼叫代码：

//code that calls it
        apiClientFactory = new ApiClientFactory();
        apiClientFactory.credentialsProvider(credentialsProvider);
        accountApiClient = apiClientFactory.build(DevsupercoolsoftwareClient.class);
...
    public static InviteCodeResponseModel createInviteCode(InviteCodeRequestModel request) {
        //request has one value, which is set to "USER"
        InviteCodeResponseModel response = accountApiClient.accountInviteCodeGet(request);
        return response;
    }

错误：

对AccountInvitEcodeGet的调用试图使用方法体执行HTTP GET调用。看来这是不允许的。一旦我把它改成一个帖子，一切都很好。

我将尝试找到一些描述这种行为的文档。如果可以的话，我会编辑这个或者把它放在评论中。

编辑：我和AWS支持部门谈过了。下面是他们向我指出的是，不可能将消息主体包含在HTTP get请求中。
