How to implement Alipay interface in php?
php实现支付宝接口的方法:首先下载支付宝接口包;然后在项目中调用支付宝接口,并对支付宝相关参数进行配置;最后新建一个PayAction控制器即可。
php实现支付宝接口的方法:
一、下载支付宝接口包
下载地址:
https://doc.open.alipay.com/doc2/detail?treeId=62&articleId=103566&docType=1
二、在项目中调用支付宝接口
调用分两步:
1、在配置文件中Conf/Config.php
文件中对支付宝相关参数进行配置:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 |

2、新建一个PayAction
控制器代码如下:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 138 139 140 141 142 143 144 145 146 147 148 149 150 151 152 153 154 155 156 157 158 159 160 161 162 163 164 165 166 167 168 169 170 171 172 173 174 175 176 177 178 179 180 181 182 183 184 185 186 187 188 189 190 191 192 193 194 195 196 197 198 199 200 201 202 203 204 205 206 207 208 209 210 211 212 213 214 215 216 217 218 219 220 221 222 223 224 225 226 227 228 229 230 231 232 233 234 235 236 237 238 239 240 241 242 243 244 245 246 247 248 249 250 251 252 253 254 255 256 257 258 259 260 261 262 263 264 265 266 267 268 269 270 271 272 273 274 275 276 277 278 279 280 281 282 283 284 285 286 287 288 289 290 291 292 293 294 295 296 297 298 299 300 301 302 303 304 305 306 307 308 309 310 311 312 313 314 315 316 317 318 319 320 321 322 323 324 325 |

3、这里有几个支付处理过程中需要用到的函数,我把这些函数写到了项目的Common/common.php
中,这样不用手动调用,即可直接使用这些函数,代码如下:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 |

三、总结几点
1、接口包中lib文件中的文件复制到Vendor后,重命名为TP规范的命名规则,为的是调用方便,当然你要改成其他名称也可以;
2、把执行支付操作(doalipay),处理异步返回结果(notifyurl),处理跳转返回结果(returnurl)三个支付接口的核心页面写到一个PayAction控制器中。
3、提交支付的页面中,可以在提交之前先把一些参数要传递的内容先通过隐藏域的方法组合好,比如金额先计算好,订单名称,订单描述等先用字符串组合好。然后提交表单,这样,在doalipay方法中只要直接构造传递参数,直接进行提交就行过了。
4、支付返回后的处理因为要在异步和跳转两个方法中都要进行相应的判断和处理,所以,把这些判断和处理写到一个自定义函数中,这样只要调用函数即可,使得代码更加清晰明了。
5、notify_url
和return_url
两种模式的返回url必须使用http://xxxxxxx这样的绝对路径,因为里是从支付宝平台返回到你的项目页面。不能使用相对路径。

When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
