What should I do when the interface encounters jsonstring

For test students who have not been exposed to interface testing , It's a new thing , R & D can skip .

Interface test returns jsonString strand , How to parameterize ？

1、 adopt IE or Chrome browser , Intercept the request content .

IE as follows , This Json take + / = And other symbols are encoded into % start %2B(+) %2F(/) %3D(=), So use Base64 Can't decode .Chrome There is no such problem , Recommended non IE Browser .

Base64 Online decoding tools ：http://tools.jb51.net/tools/base64_decode-utf8.php

Interface encountered jsonString What to do with _json

Chrome Json

Interface encountered jsonString What to do with _ clock _02

2. Use the decoding tool to decode Json Decode to get the original

Interface encountered jsonString What to do with _ clock _03

3. Parameterized original

I won't say much about this , Let's talk about it Json Three transmission formats , They are clear text Standards 、 With escape and base64 Code of .

send out , If the server standard takes precedence , If there is verification, it needs to be done first base64 After encoding, it will be sent to the server .

Tool introduction

Base64 Coding requirements 3 individual 8 Bit byte （3*8=24） Turn into 4 individual 6 Bytes of bits （4*6=24）, After the 6 Fill in two in front of the bit 0, formation 8 Bits in the form of a byte . If there are not enough characters left 3 Bytes , Then use 0 fill , Output characters using ‘=’, So the end of the output text after encoding may appear 1 or 2 individual ‘=’.

In order to ensure that the output encoding bit can read characters ,Base64 A coding table was made , For unified transformation . The size of the encoding table is 2^6=64, This is also Base64 The origin of the name .
