RCTBatchedBridge.m 错误:无效的数据消息 - 全部长度必须为:%zd.React Native，iOS 模拟器 [英] RCTBatchedBridge.m Error: Invalid data message - all must be length:%zd. React Native, iOS simulator

问题描述

我正在使用 react-native-oauth 并在尝试授权时收到此错误(请参阅底部的红色图像).我搜索并发现只有这个

当我尝试提醒 config 对象时，我收到一个关于无法将其子对象字符串化的错误.

在 chrome 调试器中查看控制台时，我得到无法读取未定义的属性 'configureProvider'"并且 configureProvider() 是 react-native-oauth 使用的内容看起来经理设置不正确，所以也许我没有很好地链接库.已检查链接是否有效.

我正在深入研究这些错误，这似乎是 NativeModules.OAuthManager 中与承诺/回调相关的问题.捕获的错误是:TypeError:无法读取未定义的属性授权".当我跳入堆栈跟踪时，我发现:

非常感谢任何帮助，谢谢.

解决方案

所以对我来说，无论出现什么问题，都是 react-native-oauth 的设置问题，因为自从我回滚到我的代码没有其他依赖项的程度(我还安装了 Firestack)并按照 react-native-oauth 的文档从头开始重新设置.我意识到我错过了 iOS/XCode 方面的一个步骤，因为当我最初尝试时我找不到文件，所以跳过了这一步:

来自 react-native-oauth 自述文件

<块引用>

接下来，导航到项目设置的相邻Build Phases"部分，找到Link Binary with Library"下拉菜单，将其展开，然后单击+"将 libOAuthManager.a 添加到列表中.

我得到的错误是从中删除了几步，但我确定以某种方式连接.经验教训:不要尝试一次做太多事情，也不要跳过必要的步骤.

I'm using react-native-oauth and getting this error (see red image at bottom) when trying to authorise. I've searched and found only this similar unanswered question. I looked into the source and found where the error is raised on line 954 and it seems it's because moduleIDs.count should equal methodIDs.count and paramsArrays.count :

  if (RCT_DEBUG && (moduleIDs.count != methodIDs.count || moduleIDs.count != paramsArrays.count)) {
RCTLogError(@"Invalid data message - all must be length: %zd", moduleIDs.count);

So, still in the source, I look for these objects and find them defined just above, on lines 943-945 and they are using RCTConvert, whose functions "...all accept a JSON value as input and map it to a native Objective-C type or class." - React's docs

So it seems like this is a transpiling and/or networking related error. But I have basically 0 knowledge on those fields and feel I've hit a barrier to investigating and wondered if anybody had any ideas on moving forward. Being new to React Native and never having done any Objective-C can't be helping me.

Also, here's my code generating the errors.

import OAuthManager from 'react-native-oauth';
import {
Alert
} from 'react-native'
var env = require('../environment.js')
const config =  {
  facebook: {
    client_id: env.getKey("FB_ID"),
    client_Secret: env.getKey("FB_SECRET")
  }
}
const manager = new OAuthManager('myAppName')
manager.configure(config);
exports.authWithFb = () => {
   manager.authorize('facebook')
     .then(resp => Alert.alert('response!' + resp))
     .catch(err => Alert.alert('error msg here: ' + err));
}

I am guessing this undefined error is related to the RCTBridge error but not sure. You can below see when I Alert the manager.authorize's caught error. TypeError: undefined is not an object (evaluating 'fn'):

Edit:

When I try to Alert the config object, I get an error about not being able to stringify it's sub-object.

When looking in console in chrome debugger, I get "Cannot read property 'configureProvider' of undefined" and configureProvider() is what react-native-oauth uses so it looks like the manager is not set up right so maybe I didn't link the library well. Have checked the linking worked.

Im digging into the errors a bit and it seems like a promise/callback related problem from NativeModules.OAuthManager. The error caught is: TypeError: Cannot read property 'authorize' of undefined. When I jump into the stack trace I find:

Any help is much appreciated, thanks.

解决方案

So for me whatever was going wrong was a setup issue with react-native-oauth because everything has fixed itself since I've rolled back to a point where my code had no other dependencies (I also had Firestack installed) and set up from scratch again following react-native-oauth's docs. I realised that there was a step on iOS/XCode's side that I had missed out because when I originally tried I couldn't find the file so just skipped that step:

From react-native-oauth readme

Next, navigate to the neighboring "Build Phases" section of project settings, find the "Link Binary with Library" drop down, expand it, and click the "+" to add libOAuthManager.a to the list.

The errors I were getting were a few steps removed from this but I'm sure connected somehow. Lessons learnt: don't try to do too many things at once and don't skip required steps.
