RJSONIO包中fromJSON中的奇怪行为 [英] Strange behaviour in fromJSON in RJSONIO package
本文介绍了RJSONIO包中fromJSON中的奇怪行为的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
好的，我正在尝试将以下JSON数据转换为R数据帧.
Ok, I'm trying to convert the following JSON data into an R data frame.
出于某种原因，RJSONIO软件包中的fromJSON仅读取大约380个字符，然后停止正确转换JSON.
For some reason fromJSON in the RJSONIO package only reads up to about character 380 and then it stops converting the JSON properly.
这是JSON:-

(我将输出截断了一点).
(I've truncated the output a little).
已正确读取R输出，直到"callConversionPerc"为止，此后JSON解析似乎已中断.我错过了一些默认参数可能会引起这种现象吗?我已经检查了未遮盖的语音标记和类似的东西，但我没有看到.
The R output has been read properly up until "callConversionPerc" and after that the JSON parsing seems to break. Is there some default parameter that I've missed that could couse this behaviour? I have checked for unmasked speechmarks and anything obvious like that I didn't see any.
肯定不是不久之后就会出现的换行符吗?
Surely it wouldn't be the new line operator that occurs shortly after, would it?
所以这似乎是换行问题.
这是我拉到R中的另一个'JSON'字符串，再次将双引号都转义了
Here's another 'JSON' string I've pulled into R, again the double quote marks are all escaped
"{\"modelId\":\"7\",\"igrp\":\"1\",\"modelName\":\"Equally Weighted\",\"modelType\":\"spread\",\"status\":200,\"matchCriteria\":\"\",\"lookbackDays\":90}\n{\"modelId\":\"416\",\"igrp\":\"1\",\"modelName\":\"First and Last Click Weighted \",\"modelType\":\"spread\",\"status\":200,\"matchCriteria\":\"\",\"lookbackDays\":90,\"firstWeight\":3,\"lastWeight\":3}\n{\"modelId\":\"5\",\"igrp\":\"1\",\"modelName\":\"First Click\",\"modelType\":\"first\",\"status\":200,\"matchCriteria\":\"\",\"lookbackDays\":90}\n{\"modelId\":\"8\",\"igrp\":\"1\",\"modelName\":\"First Click Weighted\",\"modelType\":\"spread\",\"status\":200,\"matchCriteria\":\"\",\"lookbackDays\":90,\"firstWeight\":3}\n{\"modelId\":\"128\",\"igrp\":\"1\",\"modelName\":\"First Click Weighted across PPC\",\"modelType\":\"spread\",\"status\":200,\"matchCriteria\":\"\",\"lookbackDays\":90,\"firstWeight\":3,\"channelsMode\":\"include\",\"channels\":[5]}\n{\"modelId\":\"6\",\"igrp\":\"1\",\"modelName\":\"Last Click\",\"modelType\":\"last\",\"status\":200,\"matchCriteria\":\"\",\"lookbackDays\":90}\n{\"modelId\":\"417\",\"igrp\":\"1\",\"modelName\":\"Last Click Weighted \",\"modelType\":\"spread\",\"status\":200,\"matchCriteria\":\"\",\"lookbackDays\":90,\"lastWeight\":3}\n\r\n"
当我尝试使用fromJSON进行解析时，我遇到了同样的问题，它到达第一行的最后一项，然后停止正确地进行解析.请注意，在这种新情况下，输出与为最后一项返回NULL之前的输出略有不同(而不是前一个示例中的凌乱字符串.
When I try to parse this using fromJSON I get the same problem, it gets to the last term on the first line and then stop parsing properly. Note that in this new case the output is slightly different from before returning NULL for the last item (instead of the messy string from the previous example.
$modelId
[1] "7"
$igrp
[1] "1"
$modelName
[1] "Equally Weighted"
$modelType
[1] "spread"
$status
[1] 200
$matchCriteria
[1] ""
$lookbackDays
NULL
如您所见，这些组件现在使用"$"约定，就好像它们在命名组件一样，最后一项为空.
As you can see, the components now use the "$" convention as if they are naming components and the last item is null.
我想知道这是否与fromJSON解析字符串的方式有关，并且当要求创建与已经存在的变量同名的变量时，它会失败并仅返回一个字符串或NULL.
I am wondering if this is to do with the way that fromJSON is parsing the strings, and when it is asked to create a variable with the same name as a variable that already exists it then fails and just returns a string or a NULL.
我本以为处理这种情况会被编码到RJSONIO中，因为这是JSON数据具有重复名称的相当标准.
I would have thought that dealing with that sort of case would be coded into RJSONIO as it's pretty standard for JSON data to have repeating names.
我很困惑如何解决此问题.
I'm stumped as to how to fix this.
推荐答案
JSON的两个方面似乎引起了麻烦.第一个是结尾的"\ n \ r \ n"，因此请消除它
There are two aspects of the JSON that seem to be causing trouble. The first is the trailing "\n\r\n", so get rid of that
contJSON = sub("\n\r\n$, "", contJSON)
第二个是该字符串实际上是一系列有效的JSON行，而不是单个JSON对象.因此，要么将其拆分为有效的JSON对象，然后分别进行处理
The second is that the string is actually a series of valid JSON lines rather than a single JSON object. So either split it into valid JSON objects and process each individually
lapply(strsplit(contJSON, "\n"), fromJSON, asText=TRUE)
或创建一个表示单个有效JSON对象的字符串并对其进行处理
or create a string representing a single valid JSON object and process that
fromJSON(sprintf("[%s]", gsub("\n", ",", contJSON)), asText=TRUE)
这两个都依赖于数据的详细信息，因此通常没有用.
Both of these rely on details of the data so are not generally useful.
很明显，asText是fromJSON
> args(RJSONIO::fromJSON)
function (content, handler = NULL, default.size = 100, depth = 150L,
allowComments = TRUE, asText = isContent(content), data = NULL,
maxChar = c(0L, nchar(content)), simplify = Strict, nullValue = NULL,
simplifyWithNames = TRUE, encoding = NA_character_, stringFun = NULL,
...)
NULL
因此，如果R抱怨一个未使用的参数，则可能是您实际上正在访问其他函数，尤其是rjson::fromJSON.也许search()表明rjson出现在RJSONIO之前?
So if R is complaining about an unused parameter it's likely that you're actually accessing a different function, in particular rjson::fromJSON. Perhaps search() shows that rjson appears before RJSONIO?
这篇关于RJSONIO包中fromJSON中的奇怪行为的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
