json.dumps结果不要空格

json.dumps()函数中的separators参数是一个元组，用于指定生成的 JSON 字符串中不同部分的分隔符。元组中包含两个字符串，分别表示键值对之间的分隔符和项之间的分隔符。

默认情况下，separators参数设置为( ",", ":")，即生成的 JSON 字符串中键值对之间使用逗号,分隔，键和值之间使用冒号:分隔。

如果要去掉生成的 JSON 字符串中的空格，可以将separators参数设置为( ",", ":")

python 复制代码

    import json

    input_object = {
"accId": "2023101613595110268484",
"clientId": "2023101613595110268",
"signType": "SHA256",
"sign": "64723141643f5ed6dd1e4e8e698ca822ba8683dd3fb01152656a0f94df23f8b0",
"version": "1.0",
"bizContent": "{\"captureDelayHours\":0,\"amount\":1000,\"currency\":\"TWD\",\"merchantTransactionId\":\"65a501807018de895ad4c7aa\",\"payResultUrl\":\"https://pay.9longe.net/redirect.html\",\"payCancelUrl\":\"https://pay.9longe.net/redirect.html\",\"notificationUrl\":\"http://sit-yao.sit-set:8881/thirdpart/pingpong/notify/104\",\"language\":\"ru\",\"tradeCountry\":\"RU\",\"shopperIP\":\"http://127.0.0.1\",\"merchantUserId\":\"aDT5CUq1Fb3P06MM\",\"payment_methods\":[\"VISA\",\"Mastercard\",\"NSPKMIR\",\"QIWIWALLET\"],\"goods\":[{\"name\":\"testgoods\",\"number\":\"1\",\"unitPrice\":1000}]}"
}


    # 将Python字典转换为JSON格式的字符串，并进行转义，去掉空格
    output_str = json.dumps(input_object, separators=(",", ":"))
    print(output_str)

结果
