Google云端点生成的iOS客户端无法运行

问题描述

我有一个使用GAE Python SDK 1.8.3在本地运行的python webservice。使用Google Cloud Endpoints服务生成器注释API并生成iOS客户端类后，我试图调用使用它的远程过程。

I have a python webservice running locally using GAE Python SDK 1.8.3. After annotating the API and generating iOS client classes using Google Cloud Endpoints Service Generator I'm trying to call a remote procedure using it.

如果我使用API​​ Explorer测试API ，一切正常。

If I test my api using API Explorer, everything works just fine.

当我使用iOS客户端进行呼叫时，该呼叫被web服务接收，但是该请求无法正确解码。这是我第一次使用Endpoints API，所以我不知道什么是错的。

When I call using the iOS client, the call is received by the webservice, however the request cannot be decoded correctly. This is my first time using the Endpoints API so I don't know what is wrong.

似乎发生的事情是，我的请求对象被包装在查询JSON中的资源键中。现在，当我的web服务尝试解码它时，它会产生一条警告，提示无法识别无法识别的字段：资源。而且，由于我的对象被封装在这个键中，所以它被跳过并且不会解码为消息。

What seems to be happening is that my request object is being wrapped in a "resource" key in the query JSON. Now, when my webservice tries to decode it, it yields a warning saying "No variant found for unrecognized field: resource". And, as my object is wrapped inside this key, it is skipped and never decoded to a message.

当使用API​​ Explorer进行调用时，对象不会被包装，所以一切正常。

When the call is made using the API Explorer the object is not wrapped, so everything works.

这就是我在我的web服务中所做的：

This is what I'm doing in my webservice:

@endpoints.method(SearchRequest,
                  ContactListResponse,
                  path='search', http_method='post',
                  name='api.search')
def search(self, request):
    user = request.user
    number = request.number

这就是我如何从iOS调用它：

This is how I call it from iOS:

GTLMyAPIMessagesSearchRequest * request = [[GTLMyAPIMessagesSearchRequest alloc] init];
request.user = @"[phone]";
request.number = @"[phone]";


GTLQueryMyAPI *query = [GTLQueryMyAPI queryForApiSearchWithObject:request];
[service executeQuery:query completionHandler:^(GTLServiceTicket *ticket,
                                                GTLMyAPIMessagesContactListResponse* object,
                                                NSError *error)
{
    NSArray* contacts = object.contacts;
}

我在这里做了什么令人难以置信的错误？

Am I doing anything incredibly wrong here?

推荐答案

这不是一个好的解决方案，而是现在的补丁。在进行iOS端点本地主机测试时遇到同样的问题。但是，当我使用已部署的后端时，我删除了这一行，并且一切正常。

This is not a great solution but a patch for now. I have the same problem when doing iOS endpoints localhost testing. However when I use the deployed backend I remove this line and everything is fine.

    auth.shouldAuthorizeAllRequests = YES;

仅当我添加上面的行以使用localhost时，才会发生资源密钥包装问题。所以今天早上我没有使用localhost，只是部署版本。让我知道你是否解决了这个问题。 :)显然指向部署的版本并不是首选的测试。

The "resource" key wrapping issue only happens when I add the line above to use localhost. So this morning I'm not using localhost, just the deployed version. Let me know if you fix the issue. :) Obviously pointing to the deployed version is not preferred for testing.
