（出力を少し切り捨てました）。

R 出力は「callConversionPerc」まで適切に読み取られ、その後 JSON 解析が壊れているようです。この動作を引き起こす可能性がある、見逃したデフォルトのパラメーターはありますか? マスクされていないスピーチマークと、そのような明白なものを確認しました。

確かに、直後に発生するのは改行演算子ではないでしょうか?

編集:したがって、これは改行の問題のようです。

これは、私が R に取り込んだ別の「JSON」文字列です。ここでも、二重引用符はすべてエスケープされています

"{\"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"

を使用してこれを解析しようとするとfromJSON、同じ問題が発生します。最初の行の最後の用語に到達し、適切に解析を停止します。この新しいケースではNULL、最後の項目を返す前とは出力が少し異なることに注意してください (前の例の乱雑な文字列ではありません。

$modelId
[1] "7"

$igrp
[1] "1"

$modelName
[1] "Equally Weighted"

$modelType
[1] "spread"

$status
[1] 200

$matchCriteria
[1] ""

$lookbackDays
NULL

ご覧のとおり、コンポーネントは、コンポーネントに名前を付けて最後の項目が null であるかのように "$" 規則を使用するようになりました。

これが文字列を解析する方法に関係しているかどうか疑問に思ってfromJSONおり、既に存在する変数と同じ名前の変数を作成するように求められた場合、それは失敗し、文字列または NULL を返します。

JSONデータが繰り返し名前を持つことは非常に標準的であるため、そのようなケースを処理することはRJSONIOにコード化されると思っていました。

これを修正する方法に困惑しています。

JSON には、問題を引き起こしていると思われる 2 つの側面があります。最初は末尾の「\n\r\n」なので、それを取り除きます

contJSON = sub("\n\r\n$, "", contJSON)

2 つ目は、文字列が実際には単一の JSON オブジェクトではなく、一連の有効な JSON 行であることです。したがって、それを有効な JSON オブジェクトに分割し、それぞれを個別に処理します

lapply(strsplit(contJSON, "\n"), fromJSON, asText=TRUE)

または、単一の有効な JSON オブジェクトを表す文字列を作成し、それを処理します。

fromJSON(sprintf("[%s]", gsub("\n", ",", contJSON)), asText=TRUE)

これらはどちらもデータの詳細に依存するため、一般的には役に立ちません。

asTextの主張であることは明らかです。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

したがって、R が未使用のパラメーターについて不平を言っている場合は、実際には別の関数、特に にアクセスしている可能性がありますrjson::fromJSON。おそらくsearch()、rjson が RJSONIO の前に表示されることを示していますか?
