Question

您好，这可能是一个愚蠢的问题，但是我真的很困惑如何使用rn-fetch-blob发送带有内容的POST请求！ https://github.com/joltup/rn-fetch-blob

这是我下面的POST请求代码，但抛出“无法符号化堆栈：堆栈为空”

const data = 'guid='+guid+'&username='+username+'&pass='+password;

let response = await RNFetchBlob.config({ trusty: certificate })
                .fetch('POST', httpOrhttps + "://" + ipAddress + ":" + portNumber + 
                  "/setup/", RNFetchBlob.base64.encode(data))
                .catch(async (error) => { console.error(error); });

但是我的GET帖子运行得很好

let response = await RNFetchBlob.config({ trusty: certificate})
               .fetch('GET', httpOrhttps + "://" + ipAddress + ":" + httpPort + "/setup/guid=" + guid 
                             + "&username=" + username + "&pass=" + password)
              .catch(async (error) => { console.error(error); });

Ciao，很难理解为什么，但最重要的是发生此错误的位置（我的意思是肯定会在rn-fetch-blob中发生，但准确地在何处发生）。我之所以这样说，是因为看着react native ExceptionsManager.js code，在函数reportException中，如果未接收到The stack is null（因此我们没有要分析的堆栈），它将返回prettyStack。

我找到了this，但是它很旧，没有解决方案，除了3个众所周知的命令：

rm -rf ~/.rncache
watchman watch-del-all
npm start -- reset-cache

您可能已经尝试过了。

另一件事：您拥有rn-fetch-blob的最新版本。您可以尝试将其降级到10或11（可以这样做，因为您的本地反应值为0.63）。

就是这样。如果找到其他线索，我将在此答案中添加评论。
