I am trying to send the following parameters to a server through HTTP POST:

["my_session_id","{this=that, foo=bar}"]

But the server is returning a parse error because of the quotes around the hash.

I am trying to remove them with a regex like so:

params.replaceAll("\\\"\\{", "\\{");
params.replaceAll("\\\"\\}", "\\}");

In all honestly I have no idea what I'm doing. Please help.

Thanks in advance!

    send value as JSONobject because you will get values from jsonobect on service side easy without using replace or split functions – ρяσѕρєя K Jan 19 '13 at 04:27

There's two issues here: First, you're not re-assigning the string. Strings are immutable in Java (cannot be changed), so you must assign the result. Second, you're replacing "} instead of }".

Here's what I used:

String params = "[\"my_session_id\",\"{this=that, foo=bar}\"]";
params = params.replaceAll("\\\"\\{", "\\{");
params = params.replaceAll("\\}\\\"", "\\}");
System.out.println(params);

Which prints out:

["my_session_id",{this=that, foo=bar}]

PS: Bit of advice, use JSON. Android has excellent JSON handling, and it is supported in PHP as well.

  • Are the `/`'s in `params` created by `toString()` ? – Nathan McCallum Jan 19 '13 at 04:46
  • @TheVasari Those are there to escape the `"`s when I created the string. In my code, `params` is initially equal to `["my_session_id","{this=that, foo=bar}"]`, just like yours. – Cat Jan 19 '13 at 04:47

Is there a reason you are using the regular expression replaceAll? Alternatively, you might try:

 String parameters = parameters.replace("{", "\\{").replace("}", "\\}");
