Re: Error in call to API function "files/upload": HTTP header "Dropbox-API-Arg":
good you are available
Said so, pls let me know How to fix it.
to recap:
a) my ap is written in swift, NO other components (neither official dropbox library, too big and too messy)
b) it did work since 2 month ago. now I got error
c) if I cannot see WHAT has been broken, pls sent me HINTS about, OR let mr speak with some tech guy of upper level, to get some helpful tips.

seems working !

I used a reduced version for simple string, as path:
func DB_utf8Decode(_ data: Data) -> String {
return NSString(data: data, encoding: String.Encoding.utf8.rawValue)! as String
}
func DB_asciiEscape(_ s: String) -> String {
var out: String = ""
for char in s.unicodeScalars {
var esc = "\(char)"
if !char.isASCII {
esc = NSString(format:"\\u%04x", char.value) as String
} else {
if (char == "\u{7F}") {
esc = "\\u007f"
} else {
esc = "\(char)"
}
}
out += esc
}
return out
}
as a last side note:
you had to write:
- C# (2 cersions)
- java
- JavaScript
Objective-C
Python
PHP
Swift
So 8 versions when simply accepting binary JSON on server would have prevented all this stuff? and / or fixing on server directly?
seems, as minimum, suboptimal.

Thanks for following up. I'm glad to hear you got this working, and thanks for the feedback!
a more "swift" solution for string with a copiale of Unit test:
func DB_asciiEscape(_ s: String) -> String {
let out = s.unicodeScalars.reduce("", { (partialResult: String, char: UnicodeScalar) -> String in
if !char.isASCII {
return partialResult + String(format:"\\u%04x", char.value)
} else {
if (char == "\u{7F}") {
return partialResult + "\\u007f"
} else {
return partialResult + "\(char)"
}
}
}
)
return out
}
//------ UNIT TESTS:
func testUtf8Decode(){
let unescaped = "/OUT/aaaaa＿000.jpg"
let escaped = DB_asciiEscape(unescaped)
print(escaped)
let contains = escaped.contains("uff3f000.jpg")
XCTAssert(contains, "not ecaped")
}
func testUtf8Decode2(){
let unescaped = "αβγ.jpg"
let escaped = DB_asciiEscape(unescaped)
print(escaped)
let contains = escaped.contains("\\u03b1\\u03b2\\u03b3")
XCTAssert(contains, "not ecaped")
}
