问题 i have url with this simple JSON {"result":true,"data":[{"Position":"135"}]} I tried to read it with this: $json = file_get_contents('https://...link/here..'); $obj = json_decode($json); echo $obj->result[1]->data->Position; but it not works. Where i do a mistake? Thanks for helping! 回答1: You are incorrectly addressing the data in the PHP object created from the JSON String $json = file_get_contents('https://...link/here..'); $obj = json_decode($json); echo $obj->data[0]->Position; Or if

问题 Using Swift4, iOS11.1, Xcode9.1, The following parseData method almost works. Everything seems to work fine (and a correct JSON-data set is fetched by this URLSession and JSONDecode). However, what is really surprising to me is the fact that a normal Browser shows different JSON-data (i.e. 20x as much is fetched than compared to this iOS-URLSession approach). Why is that ?? In the code below, you can find two print statements. The first showing the actual URLRequest-string (including all

问题 Does anyone know a solution to decode a base 64 format string in JMeter? I have to decode the a response, but i don't want to reinvent the wheel... Do i have to write the code by myself (hope not)? Thanks 回答1: Your solution is pretty good. However you can use Beanshell Post Processor and refer previous sampler response data as data (see JMeter Pre-defined Beanshell variables section) import org.apache.commons.codec.binary.Base64; vars.put("decoded_response", new String(Base64.decodeBase64

问题 I am using Preon to encode enum fields in a byte array. The fields of the first byte (example-byte: 0xf7=1111 01 11) are set up as this: @BoundNumber(size="2") //Corresponds to 11 private byte b1_1_notUsed; @BoundNumber(size="2") //Corresponds to 01 private ParkingBrakeSwitch parkingBrakeSwitch; @BoundNumber(size="4") private byte b1_3_notUsed; //Corresponds to 1111 Decoding works fine, thus I expect encoding the decoded object back to a byte array will yield the same byte array that I had

问题 I'm creating an application for video conferencing using media foundation and I'm having an issue decoding the H264 video frames I receive over the network. The Design Currently my network source queues a token on every request sample, unless there is an available stored sample. If a sample arrives over the network and no token is available the sample is stored in a linked list. Otherwise it is queued with the MEMediaSample event. I also have the decoder set to low latency. My Issue When

问题 There are a lot of questions and documentation about converting HTML entities and special characters to UTF8 text in PHP. And also there is the PHP documentation itself, such as this htmlspecialchars_decode() and this html_entity_decode(). However, I could not find any function/solution that clearly describes how to convert any HTML characters and special entities to UTF-8 text. All of them state something like "if you want to do this, then do that", etc. But no solution ever states " to have

问题 Simply trying to decode frames from videos. While working with Android 4+ (<5), it worked just fine. I'm using parts of the example that can be found here: http://bigflake.com/mediacodec/ "ExtractMpegFramesTest.java (requires 4.1, API 16)" The problem is - it extracts a frame, but the result Bitmap is as can be seen here (Saved an image right after decoding it): The real video of course has "real" frames, and not "stretched" 1 column. I've saved this image right after the code line: bmp
