Ok2Curl

Convert OkHttp requests into curl logs.

Usage

Add library to project dependencies. Library is hosted on jcenter.

repositories {
    jcenter()
}

dependencies {
    implementation 'com.github.mrmike:ok2curl:0.7.0'
}

To start logging requests with Ok2Curl add interceptor to OkHttp client.

OkHttpClient okHttp = new OkHttpClient.Builder()
    .addInterceptor(new CurlInterceptor(new Loggable() {
            @Override
            public void log(String message) {
                Log.v("Ok2Curl", message);
            }
        }))
    .build();

Result

With Ok2Curl set up correctly every executed request will be transformed into curl log e.g.

adb logcat -s "Ok2Curl"
curl -X GET -H "Cache-Control:max-stale=2147483647, only-if-cached" https://api.github.com/repos/vmg/redcarpet/issues?state=closed

Network interceptors

By default Ok2Curl uses application interceptors from OkHttp which is adequate for most cases. But sometimes you may want to use network interceptor e.g. to log Cookies set via CookieHandler. In such a case add interceptor the same way as below:

OkHttpClient okHttp = new OkHttpClient.Builder()
    .addNetworkInterceptor(new CurlInterceptor())
    .build();

Header modifiers

Ok2Curl allows you to modify any header before creating curl command. All you have to do is create your own modifier that implements HeaderModifier and add this modifier to CurlInterceptor. See sample for reference.

final BasicAuthorizationHeaderModifier modifier = new BasicAuthorizationHeaderModifier(new Base64Decoder());
final List<HeaderModifier> modifiers = Collections.<HeaderModifier>singletonList(modifier);

final CurlInterceptor curlInterceptor = new CurlInterceptor(new AndroidLogger(), modifiers);

Options

Ok2Curl supports basic Curl options. In order to use options use the following code:

final Options options = Options.builder()
                .insecure()
                .connectTimeout(120)
                .retry(5)
                .build();

final CurlInterceptor interceptor = new CurlInterceptor(logger, options);

Since now every Curl command will start with curl --insecure --connect-timeout 120 --retry 5...

Supported options

• --insecure
• --max-time seconds
• --connect-timeout seconds
• --retry num
• --compressed
• --location

If would like to support any new options please feel free to open PR. Full list of curl options is available here.
